Description

生物可分解防水复合纸及其制造方法 技术领域
本发明是有关于一种复合纸及其制造方法，且特别是有关于一种生物可分 解防水复合纸及其制造方法。 背景技术
随着环保意识逐渐提升，对于食品包装纸材的所衍生的食品安全问题及垃 圾处理问题等的要求也日益严格，目前的趋势是使用生物可分解的纸材取代塑 料、 保利龙等材质， 以减少地球环境的负担。
由于纸材本身不具备防水、防油等功能， 因此作为食品包装的纸材在与食 物接触面通常会附有一隔绝材料层， 例如使用 PE淋膜纸、 蜡纸等， 即是在原 纸上再加上可防水防油的材料层， 以达到防水防油的目的。
目前已发展出以生物可分解高分子材料（例如淀粉、聚乳酸等）作为淋膜 胶剂， 与纸张压合后附着在纸材表面， 可形成一耐热且防水防油的薄膜。
请参照图 1， 其为已知应用聚乳酸胶剂制造淋膜纸的方法示意图。 首先将 无纺布纸 10先予以预热， 以滚轮输送， 并夹介在硅利康滚轮 41及冷却滚轮 42之间受其滚压及同步传送； 再将聚乳酸原料 200加温成液状， 应用淋膜机 30垂直输出呈源源不断的生物可分解薄膜层 20位在硅利康滚轮 41及冷却滚 轮 42间；令生物可分解薄膜层 20在无纺布纸 10进入硅利康滚轮 41及冷却滚 轮 42前的冷却滚轮 42的侧上方，使无纺布纸 10与生物可分解薄膜层 20同时 通过两滚轮进行辗压，令生物可分解薄膜层 20披覆于无纺布纸 10—表层结合 成一体纸制品， 并以卷收轮 50卷收制成的纸制品。 请参照图 2， 其为图 1所 示的淋膜纸的侧视图。 由图 2可看出， 已知的聚乳酸淋膜纸具有两层结构， 聚 乳酸薄膜 20附着于无纺布纸 10表面。
由于已知的应用聚乳酸胶剂制造淋膜纸的方法是直接将聚乳酸原料加热 成液状后， 以淋膜机垂直输出在冷却滚轮上，使生物可分解薄膜层披覆于无纺 布纸的表层结合成一体纸制品， 因此，主要是由淋膜机来控制聚乳酸原料液的 输出，故常需使用较多的上胶量来达到均匀涂布的效果，也因此造成聚乳酸原 料的浪费及制成的纸制品薄膜厚度较厚；此外， 以此已知方法制成的聚乳酸淋 膜纸， 其淋膜仅附着于纸材表面， 应用在非一次性使用包装材上， 例如药袋、 水果防水套袋等用途上，又因为纸材与聚乳酸淋膜附着度不够而容易有被破损 脱落的缺点。 发明公开
因此本发明一方面就是在提供一种生物可分解防水复合纸制造方法，用以 改良传统淋膜方法上胶量过多， 上胶后的胶膜厚度较厚的缺点。
本发明另一方面就是在提供一种生物可分解防水复合纸，用以解决传统淋 膜纸的胶膜仅附着于纸材表面、 容易被撕除脱落的缺点。
本发明实施例提出一种生物可分解防水复合纸制造方法，包含提供一走纸 装置及一上胶装置,其中走纸装置是用以拉撑一基材，上胶装置包含一胶水槽、 一第一滚轮及一第二滚轮，其中第一滚轮转动时可沾附胶水槽中的生物可分解 胶水， 第二滚轮则可依需要调整不同位置。
将走纸装置上的基材的第一外表面与第一滚轮接触，基材的第二外表面与 第二滚轮接触，通过调整第二滚轮的位置来决定第一外表面与第一滚轮的接触 面积，并利用第一滚轮的转动及走纸装置的卷动将胶水均匀涂布至基材的第一 外表面，使胶水嵌入基材的纸浆纤维中与基材结合成一体，最后再通过一烘干 装置将胶水中的水分及溶剂等成分挥发去除，形成本发明的生物可分解防水复 合纸。
依照本发明的实施例，可进行一刮涂步骤除去或回收多余的胶水，通过刮 除部分沾附于第一滚轮上或第一外表面上的胶水以控制基材的上胶量，不但能 达到降低上胶量、 胶水再回收的目的， 上胶后的成品更具有极薄的薄膜厚度。 此外，可配合不同的使用需求或纸基材的纤维密度，调整胶水的浓度及干燥成 膜速度， 来防止胶水拉丝或残胶再结晶速度过快的现象。
本发明实施例提出一种生物可分解防水复合纸，包含一基材及一生物可分 解胶水层。基材是由纸浆纤维所构成， 具有二外表面； 生物可分解胶水层实质 上由含 1~85%重量比的聚乳酸溶液及至少 15%重量比的溶剂制成的原液， 依 浓度需要以水稀释而成的聚乳酸胶水所组成。生物可分解胶水层可部分嵌入基 材的至少一外表面的纸浆纤维中，与基材结合成一体，并在基材表面形成保护 性薄膜，而制成具有防水、抗油及高生物可分解性的复合纸材， 适用于制作各 种食品的包装纸、 一次性使用容器， 兼具环保、 食用安全性及耐用性。
根据上述可知，本发明实施例的生物可分解防水复合纸制造方法，可通过 上胶装置的独特设计及调整胶水的浓度配方来控制高结晶速度的聚乳酸溶液 在基材的上胶量，得到具有极低薄膜厚度的生物可分解防水复合纸，更可回收 多余的胶水再利用， 具有降低成本的效果。此外， 以本发明实施例的方法制成 的生物可分解防水复合纸，胶膜可嵌入纸材纤维而无法被撕除脱落， 附着度优 于一般传统淋膜纸， 可依照不同使用需求扩大纸材的应用范围。 附图简要说明

请参照图 4，其绘示依照本发明一实施例的一种制造图 3所示的生物可分 解防水复合纸的示意图。生物可分解防水复合纸的制造方法包含提供一走纸装 置及一上胶装置， 上胶装置包含一胶水槽 310、 一第一滚轮 312、 一第二滚轮 314及一烘干装置 350; 走纸装置包含至少一组放料滚轮 332及卷收滚轮 334。
将一胶水 320盛装于胶水槽 310中， 胶水 320可为以含 1〜85%重量比的 聚乳酸溶液及至少 15%重量比的溶剂制成的原液，依浓度需要以水稀释而成的 聚乳酸胶水， 依照本发明的实施例， 聚乳酸胶水的溶剂可包含醇、酮、醚或酯 类。
将第一滚轮 312部分浸置于胶水 320中，使第一滚轮 312在转动的同时可 沾附胶水 320。 一纸基材 340设置于走纸装置的放料滚轮 332及卷收滚轮 334 之间， 箭头所示方向为纸基材 340的行进方向。
纸基材 340的一外表面 342与第一滚轮 312接触，另一外表面 344与第二 滚轮 314接触，第二滚轮 314可依需要调整不同位置，通过第二滚轮 314的位 置来决定外表面 342与第一滚轮 312的接触面积，例如将第二滚轮 314往下压 可使外表面 342与第一滚轮 312的接触面积较大。第一滚轮 312的转动及走纸 装置的卷动可将胶水 320均匀涂布至纸基材 340的外表面 342上， 使胶水 320 嵌入纸基材 340的纸浆纤维中与纸基材 340结合成一体。
多余的胶水 320可进行一刮涂歩骤，利用刮涂装置 316刮除沾附于纸基材 340上的多余胶水 320以控制纸基材 340的上胶量； 最后再通过烘干装置 350 将胶水 320中的水分及溶剂等成分挥发去除，形成本发明的生物可分解防水复 合纸， 并由卷收辊轮 334收集其。
请参照图 5，其绘示依照本发明另一实施例的一种制造图 3所示的生物可 分解防水复合纸的示意图。包含提供一走纸装置及一上胶装置，上胶装置包含 一胶水槽 410、 一第一滚轮 412及一第二滚轮 414; 走纸装置包含至少一组放 料滚轮 432及卷收滚轮 434。
胶水 420盛装于胶水槽 410中，将第一滚轮 412部分浸置于胶水 420中以 沾附胶水 420。 多余的胶水 420可进行一刮涂步骤， 利用刮涂装置 416刮除沾 附于第一滚轮 412上的多余胶水 420以控制纸基材 440的上胶量。
一纸基材 440设置于走纸装置的放料滚轮 432及卷收滚轮 434之间，箭头 所示方向为纸基材 440的行进方向。 纸基材 440的一外表面 442与第一滚轮 412接触， 另一外表面 444与第二滚轮 414接触， 第二滚轮 414设置于第一滚 轮 412正上方， 使第一滚轮 412、纸基材 440及第二滚轮 414三者的接触在同 一点上， 可使第一滚轮 412与纸基材 440仅有小面积的接触。 利用第一滚轮 412的转动及走纸装置的卷动将胶水 420均匀涂布至纸基材 440的外表面 442， 使胶水 420嵌入纸基材 440的纸浆纤维中与纸基材 440结合成一体；最后再通 过烘干装置 450将胶水 420中的水分及溶剂等成分挥发去除，形成本发明的生 物可分解防水复合纸， 并由卷收辊轮 434收集其。 虽然本发明已以多个实施例公开如上，然其并非用以限定本发明，任何熟 悉此技术的人员，在不脱离本发明的精神和范围内，当可作各种的更动与润饰， 因此本发明的保护范围当视后附的权利要求书所界定的范围为准。
