彩印双向拉伸聚丙烯膜与瓦楞纸复合 制成的包装箱及其制造方法 技术领域  Packaging box made of color printing biaxially stretched polypropylene film and corrugated paper and manufacturing method thereof

本发明与彩印双向拉伸聚丙烯膜与瓦楞纸复合制成的包装箱 及其制造方法有关。  The invention relates to a packaging box made of color printing bidirectionally stretched polypropylene film and corrugated paper and a manufacturing method thereof.

背景技术 Background technique

纸箱包装是所有商品都离不开的包装，为了提高商品的价值， 性， 增加强度， 扩大使用和应用范围以及提高效率：进 了不少 的研究和改进。  Carton packaging is indispensable for all goods. In order to improve the value, sex, strength, expand the scope of use and applications, and improve efficiency: a lot of research and improvement have been made.

在传统的全纸瓦楞箱的印刷制作上已经形成了自动化程度较 高的全套生产装备， 他们是多层瓦楞形纸板的成型机及纸板切断 机， 纸箱面层纸及纸板的单张纸印刷机或纸卷连续印刷机， 瓦楞 纸板裱纸机， 瓦楞纸板印刷开槽机， 纸箱糊箱（盒）机或订箱机。  In the traditional full-paper corrugated box printing production, a full set of highly automated production equipment has been formed. They are a multi-layer corrugated cardboard forming machine and a cardboard cutting machine, a carton surface paper and a paper sheet printing machine. Or paper roll continuous printing machine, corrugated paperboard laminating machine, corrugated cardboard printing slotting machine, carton gluer (box) machine or stapler.

一般的制箱生产过程是纸卷连续印刷， 在瓦楞形纸板的成型 机上将多层纸板成型为瓦楞形以增加纸板强度， 同时打淀粉胶使 多层瓦楞纸与多层纸板贴合， 在此同时与连续印刷的纸卷粘贴形 成表层有印刷图案的瓦楞形增强的纸板， 此瓦楞纸板被纸板切断 为规格规定的尺寸后， 放入瓦楞纸板印刷开槽机按纸箱规格对其 切口开槽（这里因表层已成卷印刷， 不再印刷， 若没有成卷印刷， 瓦楞纸板就在此机上印刷表层图案）。 切口开槽后的瓦楞纸板在 纸箱糊箱机或钉箱机上装钉为规定的纸箱。  The general production process of box making is continuous printing of paper rolls. The multi-layer cardboard is formed into a corrugated shape on a corrugated cardboard forming machine to increase the strength of the cardboard. At the same time, starch glue is used to make the multi-layer corrugated paper and multi-layer cardboard affixed. A corrugated reinforced cardboard with a printed pattern on the surface is pasted with a continuous printed paper roll. This corrugated cardboard is cut to the size specified by the cardboard, and then placed in a corrugated cardboard printing slotter to slot the cutouts according to the carton specifications (here Because the surface layer has been printed in rolls, it will not be printed anymore. If there is no roll printing, the corrugated cardboard will print the surface layer pattern on this machine). The cut corrugated cardboard is nailed into a prescribed carton on a carton gluer or stapler.

目前传统的纸箱都是这样制取的， 只是设备的的大小和自动 化程度不一样， 以及印刷机器的进步， 可以更快、 更方便的生产 各种纸箱， 提高纸箱的印刷美观性和大型化。 但传统的纸箱使用 范围受到很大限制， 比如冷藏食品、 海产品、 果蔬的包装， 由于 纸箱不防潮， 要在冷库使用不得不对纸箱用浸蜡来防潮， 造成纸 箱成本太高而受到推广限制。 在纸箱表层的印刷以及卷紙的连续 印刷， 由于瓦楞纸板的厚度公差太大以及卷纸的表面太粗糙、 不 光洁、 没有光泽， 印刷的精美性和光泽、 光洁度达不到商品的需 求， 现在人们开始使用流延聚丙烯膜、 聚酯膜、 双向拉伸聚丙烯 膜在其表面用涂复方法涂一层粘结剂后去一张一张的复合或复盖 上述的切断的纸板的纸箱表层的印刷图案， 使印刷图案更光泽、 光洁和美观， 同时也增加了纸箱的强度和防潮的性能， 也扩大了 使用范围， 在纸板上及表层上印刷图案， 利用塑料膜涂复粘结剂 将一张一张纸板及表层复合或复盖主要是利用了现有传统装备和 工艺比如 OPP覆膜机或 CPP覆膜机， 也确实获得了提高装璜水 平和提高包装箱价值及商品价值的作用。 At present, traditional cartons are made in this way, but the size and automation of the equipment are different, and the advancement of printing machines can produce various cartons faster and more conveniently, improving the aesthetics and large-scale printing of cartons. However, the use of traditional carton boxes is greatly limited, such as the packaging of refrigerated food, seafood, fruits and vegetables. The carton is not moisture-proof. If it is used in a cold storage, the carton must be impregnated with wax to prevent moisture, which causes the cost of the carton to be too high and is restricted by promotion. The printing on the surface of the carton and the continuous printing of the roll paper, because the thickness tolerance of the corrugated cardboard is too large, and the surface of the roll paper is too rough, matte, and non-glossy. The exquisite printing, gloss, and finish do not meet the needs of the products. Now People began to use cast polypropylene film, polyester film, and biaxially oriented polypropylene film to apply a layer of adhesive on the surface of the film, and then go to the carton compound or cover the cut cardboard one by one. The printed pattern on the surface layer makes the printed pattern more shiny, smooth and beautiful. At the same time, it also increases the strength and moisture resistance of the carton. It also expands the scope of use. Printing patterns on cardboard and the surface layer, using plastic film to coat the adhesive. The lamination and covering of a piece of cardboard and its surface is mainly by using the existing traditional equipment and technology such as OPP laminating machine or CPP laminating machine, and it has indeed achieved an increase in the level of decoration and the value of the packaging box and the value of the goods effect.

但是若将印刷图案印刷在塑料膜上， 特别是欢向拉伸聚丙烯 膜上， 不论图案印在膜的外表面还是里表面， 由于其印刷油墨的 光洁和饱和度加上膜的光洁度和膜的折射作用， 无疑会比在纸上 的印刷更精美、 更富商品价值， 但若利用现有的纸箱的印刷机来 一张一张的印汉向拉伸聚丙烯膜， 由于膜有较强的静电作用， 根 本无法印刷及套印准确， 若用现有的塑料凹印机或柔性凸板印刷 机成卷印刷 向拉伸聚丙烯膜， 再将其按印刷图案和设计定长切 断再来利用前述的 OPP覆膜机或 CPP覆膜机等干式复合机涂粘 结剂后与切断的瓦楞纸板复合， 因加热涂复粘结剂， 膜有一定伸 长或缩短， 而影响到印刷图案的严格重复及长短不一， 若以膜上 的印刷图案为定长因前述的膜有可能在加热涂复粘结剂而产生长 短不一与已切断为定长的瓦楞纸板复合对不整齐， 加之膜有严重 的静电影响， 更不易在复合操作时与纸板对齐， 使后边纸板的切 口开槽更无法准确定位， 使纸箱 8个折边和 6个面都与设计规定 印刷图案无法对齐， 反而使各个面的印刷图案互相干扰。 若将上述成卷印刷的双向拉伸聚丙烯膜， 成卷连续的利用前 述的 OPP覆膜机或 CPP覆膜机等干式复合机涂粘结剂的同时与 切断的瓦楞纸板复合， 也仍然会因对膜加热涂复粘结剂造成膜有 一定伸长或缩短而影响到印刷图案的严格重复及长短不一进而与 切断为定长的瓦楞纸板无法准确复合和定切薄膜， 若降低加热温 度使印刷图案尽力不伸长或缩短， 虽然可能正常生产但又大大降 低复合效率和速度从而成本升高， 不经济。 However, if a printed pattern is printed on a plastic film, especially on a stretched polypropylene film, whether the pattern is printed on the outer or inner surface of the film, the smoothness and saturation of the printing ink plus the smoothness and film of the film The refraction effect will undoubtedly be more exquisite and more valuable than printing on paper. However, if you use the existing carton printing machine to print one-by-one stretched polypropylene film one by one, because the film has a stronger The electrostatic effect cannot be printed and overprinted at all. If the existing plastic gravure printing machine or flexible convex printing machine is used to roll print the stretched polypropylene film, then cut it according to the printing pattern and design to a fixed length and then use the foregoing. The dry laminating machine such as OPP laminating machine or CPP laminating machine is combined with the cut corrugated cardboard after applying the adhesive. Due to the heating and coating of the adhesive, the film is stretched or shortened, which affects the strictness of the printed pattern. Repeated and different lengths. If the printed pattern on the film is a fixed length, the aforementioned film may be coated with an adhesive during heating, resulting in uneven lengths and irregularities of the corrugated cardboard composite that has been cut to a fixed length. Have The heavy electrostatic effect makes it harder to align with the cardboard during the compound operation, making the incision of the cardboard on the back side more difficult to accurately locate, making the 8 folding edges and 6 sides of the carton unable to align with the design printing pattern, but making each side The printed patterns interfere with each other. If the above-mentioned printed biaxially stretched polypropylene film is continuously rolled into a roll and coated with an adhesive using a dry laminating machine such as the OPP laminating machine or CPP laminating machine, and it is compounded with the cut corrugated board, It will affect the strict repetition and different length of the printed pattern due to the film being stretched or shortened by applying the adhesive to the film. If the film is cut to a fixed length, the film cannot be accurately compounded and cut. If the heating is reduced, The temperature makes the printed pattern do not stretch or shorten as much as possible. Although it may be normally produced, it greatly reduces the compounding efficiency and speed, which increases the cost and is uneconomical.

因此至今我们在市场上仍只能看到预先在瓦楞纸板的面层纸 上尽力印刷精美的图案而用一层透明的双向拉伸膜或流延膜经过 涂复粘结剂后与纸板面层纸复合的彩印包装箱及盒， 而无法获得 在双向拉伸聚丙烯膜或聚丙烯合成纸上印刷精美的图案后与包装 箱的面层纸复合而制得包装箱及盒。  So far we can only see in the market that we have tried to print exquisite patterns on the surface paper of corrugated cardboard in advance and use a layer of transparent biaxially stretched film or cast film to coat the surface of the cardboard after applying adhesive Paper composite packaging boxes and boxes cannot be obtained by printing exquisite patterns printed on biaxially stretched polypropylene film or polypropylene synthetic paper with the cover paper of the packaging boxes to obtain packaging boxes and boxes.

发明内容 Summary of the Invention

本发明的目的是为了提供一种有立体感、 层次感、 精美的外 表和耐应力、 抗撕裂能力强的彩印的双向拉伸聚丙烯膜与瓦楞纸 复合制成的包装箱。  The purpose of the present invention is to provide a packaging box made of a bidirectionally stretched polypropylene film and corrugated paper with a three-dimensional impression, a layered feel, an exquisite appearance, and a color printing biaxially stretched polypropylene film with strong resistance to tearing.

本发明的另一个目的是提供一种在双向拉伸聚丙烯膜或聚丙 烯合成纸上印刷精美的彩色图案后， 再将它复合到瓦楞纸包装箱 及盒面上成为现实， 彩印的欢向拉伸聚集丙烯膜与瓦楞纸复合制 成的包装箱及制造方法。  Another object of the present invention is to provide an exquisite color pattern printed on a biaxially stretched polypropylene film or polypropylene synthetic paper, and then compound it on a corrugated packaging box and box surface to become a reality. Packaging box made by stretching and collecting acrylic film and corrugated paper and manufacturing method thereof.

本发明是的目的是这样来实现的：  The purpose of the present invention is to achieve this:

本发明包装箱包括包装箱板， 包装箱板是由默向拉伸聚丙烯 膜和通过树脂层与双向拉伸聚丙烯膜粘结的纸板复合形成的面 层、 里层、 位于面层与最里层之间的至少一层的瓦楞形纸板制成 的增强层构成，其特征是在双向拉伸聚丙烯膜的外表面和 /或里表 面有彩印的图案印刷层， 图案印刷层在膜的外表面有立体感、 有 饱和度、 有层次、 增加精美和实物感， 这种情况使用聚丙烯合成 纸印刷最好， 因膜是珠光膜， 呈纸白色， 纸板可用回收料纸板。 图案印刷层在膜的里表面， 图案更有光泽、 光洁、 可以不受磨损、 耐久并更符合卫生要求， 这种情况一般用透明聚丙浠膜； 若在透 明膜的里表面印刷底色比如瓷白、 银灰、 金色， 在膜的外表面印 刷图案， 可以获得更特别印刷效果， 若采用传统的印刷方法在纸 板表面先印刷然后再复盖一层透明膜 ，就一定没有采用这种印刷 的彩印效果，双向拉伸聚丙烯膜本身有不耐应力、 易撕裂等缺陷， 但电暈处理后特别是处理为珠光合成纸后有比其它膜更好的印刷 性能， 再与纸板复合， 耐应力、 抗撕裂的性能也得到了改善， 成 为了一种合成材料， 它们有了更高的强度。 The packaging box of the present invention includes a packaging box board. The packaging box board is a surface layer, an inner layer, a surface layer, and an outer layer formed by compositely forming a polypropylene film and a cardboard bonded by a resin layer and a biaxially oriented polypropylene film. The reinforcing layer made of at least one layer of corrugated cardboard between the inner layers is characterized in that a color printing pattern printing layer is provided on the outer surface and / or the inner surface of the biaxially oriented polypropylene film, and the pattern printing layer is on The outer surface has a three-dimensional effect, saturation, layering, increased exquisiteness and physical sense. In this case, polypropylene is used for synthesis. Paper printing is best, because the film is pearlescent film, paper white, cardboard can be recycled cardboard. The pattern printing layer is on the inner surface of the film. The pattern is more shiny, smooth, can be free from abrasion, durable and more in line with sanitary requirements. In this case, a transparent polypropylene film is generally used; if the inner color of the transparent film is printed on the inner surface, such as porcelain White, silver gray, gold, printing patterns on the outer surface of the film can obtain a more special printing effect. If the traditional printing method is used to print on the surface of the cardboard first and then cover a layer of transparent film, the color printing of this printing must not be used. Effect, biaxially oriented polypropylene film itself has defects such as resistance to stress and easy tearing, but it has better printing performance than other films after corona treatment, especially after being processed into pearlescent synthetic paper. The tear resistance has also been improved to become a synthetic material, which has higher strength.

上述的包装箱板的最里层是汉向拉伸聚丙烯膜与纸板通过树 脂粘结复合形成的， 且默向拉伸聚丙烯膜在最里层， 面层和最里 层都有默向拉伸聚丙烯膜后包装箱的纸板有比传统纸箱的纸板有 更高的承压能力， 包装箱堆高可比传统箱高 30% ~ 50%, 纸板的 防潮、 防水能力大大提高， 解决了冷冻物品的包装存储难题， 若 在里层聚丙烯膜上也彩印图案， 可以提高其商业价值， 提高包装 箱的制造难度， 有益防伪， 在里层制成这层复合彩印层， 其方法 也类同面层的成型方法。  The innermost layer of the aforementioned packaging box board is formed by resin bonding of the Chinese-oriented stretch polypropylene film and cardboard, and the silent-oriented polypropylene film is at the innermost layer, and the surface layer and the innermost layer have silent orientation. The cardboard of the packing box after stretching the polypropylene film has higher pressure bearing capacity than the cardboard of the traditional carton. The packing height of the packing box can be 30% ~ 50% higher than that of the traditional box. The moisture and water resistance of the cardboard is greatly improved, which solves the freezing problem. The problem of packaging and storage of articles. If there is also a color printing pattern on the polypropylene film on the inner layer, it can increase its commercial value, increase the difficulty of manufacturing the packaging box, and be beneficial to anti-counterfeiting. The method of making this composite color printing layer on the inner layer is similar. Surface layer forming method.

上述的包装箱板面层的双向拉伸聚丙烯膜是透明的单层膜结 构， 彩印的图案印刷层在双向拉伸聚丙烯膜的外表面和 /或里表 面， 默向拉伸的聚丙烯若没有加入无机填料或少加无机填料如碳 酸钙、 二氧化钛， 其拉伸后膜有更好的透明度， 膜更光洁， 若要 在膜的里表面印刷图案， 必须使用透明膜才能突出印刷图案的效 果， 但使用透明膜可以保护印刷图案不受磨损， 图案因膜的光折 射作用显得更光泽、 光洁、 更艳丽， 能增加箱的商业价值。  The above-mentioned biaxially oriented polypropylene film of the surface of the packaging board is a transparent single-layer film structure. The color printing pattern printing layer is on the outer surface and / or the inner surface of the biaxially oriented polypropylene film. If no inorganic filler is added or inorganic fillers such as calcium carbonate and titanium dioxide are added, the stretched film will have better transparency and the film will be smoother. To print the pattern on the inner surface of the film, a transparent film must be used to highlight the printed pattern. Effect, but the use of a transparent film can protect the printed pattern from abrasion, and the pattern appears more shiny, smooth, and more beautiful due to the light refraction of the film, which can increase the commercial value of the box.

上述的包装箱板的欢向拉伸聚丙烯膜是含无机填料单层结构 的仿纸的珠光膜， 膜表面以无机填料为核的周边有因膜的默向拉 伸形成的微孔， 彩印的图案印刷层在膜的外表面， 在膜中加入无 机填料碳酸钙、 二氧化钛， 当对膜进行双向拉伸时， 膜中的聚合 物被拉伸， 但以无机填料为核的周边会产生很多微孔， 加上用电 晕对膜表面进行电暈处理， 膜表面会产生大量粗糙的凹凸， 结合 微孔， 膜就获得了纸面的印刷性能， 可以快速快干的在膜上印刷 各种精美的图案， 印刷质量和效率都提高了， 这种膜加上二氧化 钛的分散折射作用使纸呈珠光白色， 因产生大量微孔， 膜的比重 也降低了， 膜的比重一般在 0.8 以下， 我们称这种膜为聚丙烯合 成珠光纸， 当然这种膜也可以制成有颜色的珠光膜， 相对透明膜 而言节约了材料， 获得了纸的印刷性能， 与纸板复合后而提高了 强度， 还因膜本身具有遮蔽性呈纸白色， 与膜复合的纸板可以不 用白色铜板纸作底色， 可以用一般的纸， 甚至可以用回收纸造的 纸板， 因此采用这种加有无机填料的欢向拉伸的呈纸白色的珠光 膜， 与用透明膜更节约材料成本。 The above-mentioned stretch-oriented polypropylene film of packaging box board is a pearlescent film of imitation paper containing a single-layer structure containing an inorganic filler. The micropores formed by stretching are printed on the outer surface of the film. The inorganic filler calcium carbonate and titanium dioxide are added to the film. When the film is stretched in both directions, the polymer in the film is stretched, but the inorganic filler is used. There are many micropores around the nucleus. In addition, corona treatment of the film surface with corona will generate a lot of rough unevenness on the surface of the film. Combined with the micropores, the film will obtain the printing performance of the paper surface, which can quickly and quickly dry. Various exquisite patterns are printed on the film, and the printing quality and efficiency are improved. This film plus the titanium dioxide's dispersed refraction effect makes the paper pearly white. Due to the large number of micropores, the specific gravity of the film is also reduced. The specific gravity is generally below 0.8. We call this film a polypropylene synthetic pearl paper. Of course, this film can also be made into a colored pearl film. Compared with transparent films, it saves material and obtains the printing performance of paper. After the compounding, the strength is improved, and the film itself is white because the film has shielding properties. The paperboard compounded with the film can be used without the white copper paper as the background color, and ordinary paper can be used. Even recycled paper can be made of cardboard, so using this paper was added with a white pearl film inorganic filler Huan stretched, the film is more transparent material cost savings.

上述的包装箱板的双向拉伸聚丙烯膜是三层膜结构的仿纸的 珠光膜， 每层膜中都分别加入无机填料， 膜表面以无机填料为核 的周边有因膜的汉向拉伸形成的微孔， 彩印的图案印刷层在膜的 外表面， 如同前述膜中因加入无机填料且双向拉伸后形成微孔， 加之电暈处理有了纸的印刷性能， 但又仍具有膜的强度， 与纸板 复合后提高了包装箱的强度和扩大了用途， 我们称之为合成纸， 这种膜是一种很好的材料， 上述单层珠光膜仍然有些缺陷， 因是 单层膜， 因拉伸工艺的限制， 加入的无机填料比例不能高， 高了 后， 一是单层膜双向拉伸膜时易破膜使膜的合格率不高， 因此生 产 20 μ ιη以下的膜有难度， 二是因加入无机填料不够多， 拉伸后 的制品比重虽然比透明膜低， 但还是在 0.75以上， 加之单层膜结 构无机填料易暴露在膜面，印刷时易落粉也影响印刷质量和效率， 为了有更低比重， 有更薄的珠光膜能在包装箱上应用而降低这种 包装箱的成本，我们采用了三层膜结构的汉向拉伸聚丙烯珠光膜， 采用这种膜， 可在中间层加更多比例的无机填料， 而两个面层加 入少量无机填料只要能满足拉伸后的微孔加电暈处理后的凹凸能 满足印刷性能即可， 这样保证了印刷性能后， 可以因中间层的大 量无机物的加入， 拉伸后珠光膜可以有低于 0.7 比重， 更节约材 料， 同时三层共挤双向拉伸也可获得 30 μ πι至 20 μ ιη以下的珠 光膜， 用这种珠光膜印刷更精美、 效率也高， 材料成本更低， 增 加包装箱的竟争力。 The biaxially oriented polypropylene film of the packaging box board is a three-layer film-like pearlescent film of imitation paper. Each layer of the film is separately added with an inorganic filler. The surface of the film is made of inorganic filler as the core. The micropores formed by stretching are printed on the outer surface of the film, as in the aforementioned film, the micropores are formed after the inorganic filler is added and bidirectionally stretched. In addition, the corona treatment has the printing performance of the paper, but it still has the film. After being combined with cardboard, the strength of the packing box is increased and the use is expanded. We call it synthetic paper. This film is a good material. The single-layer pearlescent film still has some defects because it is a single-layer film. Due to the limitation of the stretching process, the proportion of the inorganic filler added cannot be high. After it is high, the first is that the single-layer film is easy to break when the film is bidirectionally stretched, so that the qualification rate of the film is not high. Therefore, the production of films below 20 μm has Difficulty, because the inorganic filler is not added enough, although the specific gravity of the stretched product is lower than that of the transparent film, it is still above 0.75. In addition, the single-layer film structure of the inorganic filler is easy to expose on the film surface, and it is easy to fall powder when printing. Printing quality and efficiency, in order to have a lower specific gravity, there are thinner pearlescent films that can be applied to packaging boxes to reduce this. For the cost of the packaging box, we have adopted a three-layer film structure of the Chinese-oriented stretch polypropylene pearlescent film. With this film, a larger proportion of inorganic filler can be added to the middle layer, and a small amount of inorganic filler can be added to the two surface layers as long as it can It can meet the printing performance after the micropores and corona treatment after stretching can meet the printing performance. After the printing performance is guaranteed, the pearlescent film after stretching can have a specific gravity of less than 0.7 due to the addition of a large amount of inorganic substances in the intermediate layer. It is more material-saving. At the same time, a three-layer co-extrusion biaxial stretching can also obtain a pearlescent film below 30 μm to 20 μm. With this pearlescent film, printing is more exquisite, the efficiency is higher, the material cost is lower, and the packaging box is increased. Be competitive.

用这种方法制取的包装箱， 关健是利用了瓦楞纸板要复合一 层面层纸板， 利用这层面层纸板作双向拉伸膜的载体， 将很容易 随温度和环境条件发生伸长或缩短变化的欢向拉伸薄膜在印刷有 精美图案后， 及时的将其与这层面层纸复合成为合成材料使其减 少变化， 只要适当保持合成材料的存储温度 (最好在 16°C ~ 23 °C 之间）， 特别注意保持对纸的变化影响大的相对湿度 (最好是在 60 ~ 70 %之间），合成材料的变化就基本不影响后工序的加工和制 作， 就可以使我们发明的目的可以实现。 因为采用了彩印的双向 拉伸聚丙烯膜或聚丙烯合成纸作面层材料， 不仅增加了美观和商 品价值， 还增加了纸箱的承压及各种强度， 扩大了使用范围， 特 别是冷冻食品的包装应用， 由于采用了默向拉伸膜特别是聚丙烯 珠光合成纸， 使纸箱面层纸的使用等级由从前的白色铜板纸板变 成了普通回用纸制成的纸板，可以大大降低成本。 由于采用了双向 拉伸聚丙烯合成纸， 不仅印刷性能提高， 图案更精美、 光洁， 而 且与在纸箱面层纸上印刷精美图案比较节约了油墨费用， 类似的 应用合成材料的复合技术， 还可以将纸箱包装的里层也用合成材 料代替， 这将为果蔬食品、 海产品的冷冻运输和存储提供更好的 防水、 防湿、 防潮的包装产品。 For the packaging box made by this method, Guan Jian uses corrugated cardboard to compound a layer of cardboard, and uses this layer of cardboard as a carrier for the biaxially stretched film, which will easily expand or contract with temperature and environmental conditions. After changing the exquisite stretch film with a beautiful pattern, it can be compounded with this layer of paper in time to become a synthetic material to reduce the change. As long as the storage temperature of the synthetic material is properly maintained (preferably at 16 ° C ~ 23 ° C), pay special attention to maintaining the relative humidity that has a great impact on the change of the paper (preferably between 60 ~ 70%), the change of the synthetic material will not substantially affect the processing and production of the subsequent process, which can make us invent The purpose can be achieved. Because the color printed biaxially stretched polypropylene film or polypropylene synthetic paper is used as the surface layer material, it not only adds beauty and quotient The product value also increases the pressure and various strength of the carton, and expands the scope of use, especially for frozen food packaging applications. Due to the use of a stretch film, especially polypropylene pearlescent synthetic paper, the carton surface paper The use grade has been changed from the former white copper board to ordinary recycled paper, which can greatly reduce costs. Due to the use of biaxially stretched polypropylene synthetic paper, not only the printing performance is improved, the patterns are more exquisite and smooth, but also the ink cost is saved compared with the exquisite patterns printed on the carton surface paper. Similar composite technology using composite materials can also be used. The inner layer of the carton packaging is also replaced with synthetic materials, which will provide better waterproof, moisture-proof and moisture-proof packaging products for the frozen transportation and storage of fruit and vegetable food and seafood.

采用了上述方法制取的包装箱， 与传统的纸箱印刷和目前看 到的纸塑复合的方法制取包装箱比较，提高了效率 10倍以上，有 很好的经济效益和社会效益。  Compared with the traditional carton printing and the paper-plastic composite method used to make packaging boxes, the packaging boxes made by the above method have improved the efficiency by more than 10 times, and have good economic and social benefits.
