Description
本技術係關於一種包裝用膜。更詳細而言，關於一種可容易地開封包裝體之包裝用膜及使用該膜之膜包裝體與使用該膜之膜包裝方法。The present technology relates to a packaging film. More specifically, the present invention relates to a packaging film that can be easily unsealed, a film packaging body using the film, and a film packaging method using the film.
作為商品之包裝方法，已知一種被稱為收縮包裝之包裝方法。收縮包裝係使熱收縮性膜密接於被包裝物之形狀，並藉由熱封而密封之方法。As a packaging method of a product, a packaging method called shrink packaging is known. Shrink packaging is a method in which a heat-shrinkable film is brought into close contact with the shape of a packaged object and sealed by heat sealing.
收縮包裝用於例如光碟等記錄媒體之包裝。此種製品多數情況下係將光碟等記錄媒體收容於塑料外殼等後收縮包裝，但由於外殼之形狀中凹凸較少，故有膜密接於外殼，難以開封之問題。Shrink packaging is used for packaging of recording media such as optical discs. In many cases, such a product is a shrink-wrapped package in which a recording medium such as an optical disc is housed in a plastic case. However, since the shape of the case is small, there is a problem that the film is tightly attached to the case and it is difficult to open it.
於專利文獻1，揭示一種疊膜之包裝構造，該疊膜係為了便於開封箱形狀之被包裝物，將被包裝物包裹並將端部重合進行密封，且於密封部之一部分設置有由滿版印刷形成之開封口部，且特徵在於，在開封口部之一部分，設置有由網點印刷或無印刷形成之弱接著部分。

以下，一面參照圖式，一面對用以實施本技術之較佳之實施形態進行說明。再者，以下說明之實施形態係表示本技術之代表性實施形態或變化形態者，不應藉此狹義地解釋本技之範圍。
說明按照如下順序進行。Hereinafter, a preferred embodiment for implementing the present technology will be described with reference to the drawings. In addition, the embodiments described below represent representative embodiments or variations of the technology, and the scope of the technology should not be interpreted in a narrow sense.
The explanation is performed in the following order.
1.關於本技術之包裝用膜之基本構造
2.關於第一實施形態例之構成
3.關於第二實施形態例之構成1. Basic structure of the packaging film of this technology
2. Configuration of the first embodiment
3. Structure of the second embodiment
＜1.關於本技術之包裝用膜之基本構造＞
使用圖1～圖3，對本技術之包裝用膜之基本構造進行說明。
圖1係表示本技術之包裝用膜之基本構造之圖。圖2係圖1中以虛線表示之部分A之放大圖。圖3係自本技術之包裝用膜之切割部向相鄰之切割部撕裂膜時之放大圖。<1. Basic structure of packaging film of the present technology>
The basic structure of the packaging film of this technology is demonstrated using FIGS. 1-3.
FIG. 1 is a diagram showing a basic structure of a packaging film of the present technology. FIG. 2 is an enlarged view of a portion A indicated by a dotted line in FIG. 1. FIG. 3 is an enlarged view when a film is torn from a cutting portion of a packaging film of the present technology to an adjacent cutting portion.
於本技術之包裝用膜中，設置有如圖1所示之切斷預定線1。切斷預定線1由排列之複數個切割部2構成。切割部2具備第1切割線2a與自第1切割線2a朝開封方向D1側彎曲之第2切割線2b。The packaging film of the present technology is provided with a planned cutting line 1 as shown in FIG. 1. The planned cutting line 1 is constituted by a plurality of cutting sections 2 arranged. The cutting section 2 includes a first cutting line 2a and a second cutting line 2b that is bent from the first cutting line 2a toward the unsealing direction D1.
第1切割線2a與第2切割線2b之彎曲部2r亦可彎折成大致直角，較佳為彎曲形狀。藉由將彎曲部2r設為彎曲形狀，可防止開封時膜朝意外之方向撕開，例如朝第1切割線2a之延長方向撕開等。The curved portion 2r of the first cutting line 2a and the second cutting line 2b may also be bent at a substantially right angle, and is preferably a curved shape. By setting the curved portion 2r to a curved shape, it is possible to prevent the film from tearing in an unexpected direction during opening, such as tearing in the direction in which the first cutting line 2a extends.
如圖2所示，切割部2構成為位於開封方向D1之近前側之切割部21之第2切割線21b之延長線與位於開封方向D1之裏側之相鄰之切割部22之第1切割線22a相交。即便如圖3之T1
或T3
般，裂縫自第2切割線21b向左右方向裂開，但由於能夠以相鄰之切割部22之第1切割線22a阻止，故亦可使膜朝所期望之方向開裂。
再者，於本說明書中「與切割線相交」不僅指切割線彼此交叉之構成，亦包含一條切割線之端部與另一條切割線相接之構成。As shown in FIG. 2, the cutting portion 2 is configured as an extension line of the second cutting line 21 b of the cutting portion 21 located near the front side in the unsealing direction D1 and a first cutting line of the adjacent cutting portion 22 located inside the unsealing direction D1. 22a intersect. Even if the crack is split from the second cutting line 21b to the left and right as shown by T 1 or T 3 in FIG. 3, the film can be directed toward the surface because it can be stopped by the first cutting line 22a of the adjacent cutting portion 22. Crack in the desired direction.
Moreover, in the present description, "intersecting with the cutting line" means not only a configuration in which the cutting lines cross each other, but also a configuration in which the ends of one cutting line are in contact with another cutting line.
於圖2中，切割部21之第1切割線21a之尺寸a與第2切割線21b之尺寸b之比並未特別限定，但於將尺寸b設為1時，尺寸a較佳為1以上，更佳為2以上。藉由使尺寸a大於尺寸b，認為更能發揮圖3所示之相鄰之切割部22之第1切割線22a阻止裂縫T1 至T3 之效果。In FIG. 2, the ratio of the size a of the first cutting line 21 a of the cutting portion 21 to the size b of the second cutting line 21 b is not particularly limited, but when the size b is set to 1, the size a is preferably 1 or more. , More preferably 2 or more. By making the dimension a larger than the dimension b, it is considered that the effects of preventing the cracks T 1 to T 3 by the first cutting lines 22 a of the adjacent cutting portions 22 shown in FIG. 3 are more exhibited.
進而，於圖2中，切割部21之第2切割線21b之延長線與相鄰之切割部22之第1切割線22a之交點P至第1切割線22a之前端的間隔c較佳為0以上且尺寸a以下，更佳為大於0且小於尺寸a。若使間隔c大於0且小於尺寸a，則由於交點P位於較第1切割線22a之兩端部更內側，故即便裂縫自第2切割線21b向左右任一方向裂開，亦可利用相鄰之切割部22之第1切割線22a阻止。又，若使間隔c大於0且小於尺寸a，則如圖1所示，切斷預定線1相對於開封方向D1成為傾斜方向。因此，於先前之包裝構造或設置有打孔眼線之膜中難以如設想般開封，容易朝相對於開封方向傾斜之方向開封。Further, in FIG. 2, the interval c from the intersection P between the extension line of the second cutting line 21 b of the cutting portion 21 and the first cutting line 22 a of the adjacent cutting portion 22 to the front end of the first cutting line 22 a is preferably 0 or more. And the dimension a or less is more preferably larger than 0 and smaller than the dimension a. If the interval c is larger than 0 and smaller than the dimension a, the intersection point P is located more inward than both ends of the first cutting line 22a. Therefore, even if the crack is split from the second cutting line 21b to either left or right, the phase can be used. The first cutting line 22a of the adjacent cutting portion 22 is blocked. When the interval c is larger than 0 and smaller than the dimension a, as shown in FIG. 1, the planned cutting line 1 is inclined with respect to the unsealing direction D1. Therefore, it is difficult to open the seal in the previous packaging structure or the film provided with the perforated eyeliner, and it is easy to open the seal in a direction inclined to the opening direction.
再者，自切割部21之第2切割線21b之前端至交點P之間隔e於將尺寸b設為1時，較佳為0.5～1.75。藉由將間隔e設為上述範圍，可縮小如圖3之T1 或T3 般裂縫自第2切割線21b向左右裂開之範圍，可更確實地開封。The distance e from the front end of the second cutting line 21b of the cutting portion 21 to the intersection point P is 0.5 to 1.75 when the dimension b is set to 1. By the above range interval e, can be reduced as shown in the T 1 or T 3 cracks from the second cut line 21b to the range of about 3 split like, can be more reliably opened.
＜2.關於第一實施形態例之構成＞
使用圖4，對第一實施形態之構成進行說明。圖4係表示利用本技術之包裝用膜4包裝被包裝物3之包裝體之立體圖。於第一實施形態之包裝用膜4，設置有以開封開始部5為起點間隔逐漸擴大之一對切斷預定線1a及1b。<2. Configuration of First Embodiment Example>
The configuration of the first embodiment will be described using FIG. 4. FIG. 4 is a perspective view showing a package body using the packaging film 4 of the present technology to package a package 3. The packaging film 4 according to the first embodiment is provided with a pair of planned cutting lines 1 a and 1 b which gradually expands with a gap gradually starting from the unsealing start portion 5.
使用本技術時，被包裝物3之形狀並無特別限定，例如為長方體狀、圓柱狀等。尤其，於被包裝物3為如收容記錄媒體之塑料外殼之平板狀且有稜角之長方體之情形時，由於外殼之形狀中凹凸較少，故包裝用膜4密接於外殼，於先前之包裝構造中難以如設想般開封，故可更有效地使用本技術。When using this technique, the shape of the packaged object 3 is not particularly limited, and is, for example, a rectangular parallelepiped or a cylindrical shape. In particular, in the case where the packaged object 3 is a flat and angular rectangular parallelepiped, such as a plastic case for recording media, the packaging film 4 is closely adhered to the case because there are fewer irregularities in the shape of the case, which is in the previous packaging structure It is difficult to open as expected, so this technology can be used more effectively.
包裝用膜4可使用具有熱收縮性及熱接著性之素材，可使用例如聚丙烯。被包裝物3藉由將包裝用膜4之端部熱密封被收縮包裝。於被包裝物3之正面設置有密封部41，於被包裝物3之兩側側面設置有密封部42。The packaging film 4 can be made of a material having heat shrinkability and thermal adhesiveness, and for example, polypropylene can be used. The packaged object 3 is shrink-wrapped by heat-sealing the end of the packaging film 4. Sealing portions 41 are provided on the front surface of the packaged object 3, and sealing portions 42 are provided on both side surfaces of the packaged object 3.
又，於密封部41之一部分，設置有於兩側具有切口之開封開始部5。該開封開始部5較佳為與密封部41之其他部分相比為弱黏著或非黏著。例如，若於包裝用膜4之密封面之內側實施箭頭形狀之印刷，且於包裝步驟之加熱處理時使其熱熔接，則於被實施有印刷之部分，形成黏著力較未實施印刷之部分弱之弱黏著部或非黏著部。可將如此形成之弱黏著部或非黏著部設為開封開始部5。於開封時，用手指抓住該開封開始部5，可自切斷預定線1a及1b容易地開封包裝用膜4。再者，開封開始部5之兩側之切口之寬度並未特別限制，但為了容易抓住開封開始部5，較佳為50 mm。Further, a part of the sealing portion 41 is provided with an unsealing start portion 5 having cutouts on both sides. The unsealing start portion 5 is preferably weakly adhered or non-adhered compared to other portions of the seal portion 41. For example, if an arrow-shaped printing is performed on the inside of the sealing surface of the packaging film 4 and it is thermally welded during the heat treatment of the packaging step, the portion where the printing is performed will have a lower adhesion than the portion where the printing is not performed. Weak adhesion or non-adhesion. The weakly adhered portion or the non-adhered portion thus formed may be set as the unsealing start portion 5. At the time of unsealing, the unsealing start portion 5 is grasped with a finger, and the packaging film 4 can be easily unsealed by cutting the planned lines 1a and 1b. In addition, the width of the cuts on both sides of the unsealing start portion 5 is not particularly limited, but in order to easily grasp the unsealing start portion 5, it is preferably 50 mm.
本技術之包裝用膜4中，藉由切斷預定線1a及1b之各者具有上述1.所示之基本構造，即便開封方向D1與切斷預定線之方向D2不一致，亦可容易地開封。藉由將切斷預定線1a及1b設置成向被包裝物3之端部傾斜，可於沿切斷預定線1a及1b剝開包裝用膜4時擴大開口，而能夠容易地取出其中之製品。再者，上述1.中說明之圖1至圖3表示切斷預定線1b側之切割部2，切斷預定線1a之切割部2之方向與切斷預定線1b左右對稱。即，構成為切斷預定線1a之第1切割線2a之前端與切斷預定線1b之第1切割線2a之前端均朝向被包裝物3之中央方向。In the packaging film 4 of the present technology, each of the planned cutting lines 1a and 1b has the basic structure shown in 1. above, and even if the unsealing direction D1 does not match the direction D2 of the planned cutting line, it can be easily opened. . By setting the planned cutting lines 1a and 1b to be inclined toward the ends of the packaged object 3, the opening can be enlarged when the packaging film 4 is peeled off along the planned cutting lines 1a and 1b, and the products therein can be easily taken out. . In addition, FIGS. 1 to 3 described in 1. above show the cutting portion 2 on the side of the planned cutting line 1b, and the direction of the cutting portion 2 of the planned cutting line 1a is symmetrical to the planned cutting line 1b. That is, both the front end of the first cutting line 2a and the front end of the first cutting line 2a of the planned cutting line 1a are directed toward the center of the packaged object 3.
又，於調節本技術之包裝用膜之切割部之尺寸a及b、間隔c及e之後，進而亦可使切斷預定線1a及1b之角度變化。於該情形時，切斷預定線1a及1b之角度θ較佳為21～65度。若角度θ未滿21度，則有膜於開封中途朝與切斷預定線不同之方向裂開之可能性。藉由使切斷預定線之角度θ變化，可避開印刷於包裝用膜4之說明文字等而設置切斷預定線。In addition, after adjusting the dimensions a and b, the intervals c, and e of the cutting portion of the packaging film of the present technology, the angles of the planned cutting lines 1a and 1b can also be changed. In this case, the angle θ of the cut-off lines 1a and 1b is preferably 21 to 65 degrees. If the angle θ is less than 21 degrees, there is a possibility that the film is cracked in a direction different from the planned cutting line in the middle of opening. By changing the angle θ of the planned cutting line, it is possible to provide the planned cutting line, avoiding the explanatory text printed on the packaging film 4 and the like.
＜3.關於第二實施形態例之構成＞
使用圖5～圖7，對第二實施形態之構成進行說明。圖5及圖7係自上方觀察以包裝用膜4包裝之包裝體之圖。圖6係圖5中以虛線B表示之部分之放大圖。<3. Configuration of Second Embodiment Example>
The configuration of the second embodiment will be described with reference to Figs. 5 to 7. 5 and 7 are views of a packaging body packaged with the packaging film 4 as viewed from above. FIG. 6 is an enlarged view of a portion indicated by a broken line B in FIG. 5.
如圖5所示，可將切斷預定線1a及1b之起始端側11a及11b與切斷預定線1a及1b之終端側12a及12b之斜率於例如B部分變化。該等預定線如圖6所示，起始端側11b之自第2切割線211b之前端至交點P1 之間隔e1 較終端側12b之自第2切割線212b之前端至交點P2 之間隔e2 更窄。再者，切斷預定線1a及1b之起始端側11a及11b之長度方向之距離X-1較佳為5～15 mm，間隔e1 於將尺寸b設為1時較佳為0.5，間隔e2 於將尺寸b設為1時較佳為1～1.75。As shown in FIG. 5, the slopes of the start end sides 11 a and 11 b of the planned cut lines 1 a and 1 b and the terminal ends 12 a and 12 b of the planned cut lines 1 a and 1 b may be changed, for example, in part B. Such a line shown in Figure 6, the distal end 11b of the distal end side from the second cut line 211b to the intersection P of the interval 1 e 1 side than the terminal 12b of the second cut line 212b from the interval 2 to the intersection of the starting end P e 2 is narrower. Further, the cutting start end side 1a and 1b of a predetermined length 11a and 11b from the direction of X-1 is preferably 5 ~ 15 mm, a size in the interval e 1 b is preferably 0.5 to 1:00, the spacing e 2 is preferably 1 to 1.75 when the dimension b is set to 1.
由於切斷預定線1a及1b之起始端側11a及11b位於接近開封開始部5之位置，故需沿切斷預定線11a及11b更確實地開封。又，於用手指抓住開封開始部5進行開封時，朝開封方向D1之力會較大地施加於起始端側11a及11b。因此，起始端側11a及11b之間隔e1 較佳為較終端側12a及12b之間隔e2 窄。又，藉由改變間隔e之大小，可微調整切斷預定線1a及1b之斜率，可避開印刷於包裝用膜4之說明文字等而設置切斷預定線。Since the starting end sides 11a and 11b of the planned cutting lines 1a and 1b are located close to the unsealing start portion 5, it is necessary to open the seal more reliably along the planned cutting lines 11a and 11b. Further, when the unsealing start portion 5 is grasped with a finger for unsealing, a large force in the unsealing direction D1 is applied to the start end sides 11a and 11b. Therefore, the interval e 1 between the leading end sides 11 a and 11 b is preferably narrower than the interval e 2 between the terminal end sides 12 a and 12 b. In addition, by changing the size of the interval e, the slope of the planned cutting lines 1a and 1b can be finely adjusted, and the planned cutting line can be set away from the explanatory text printed on the packaging film 4.
再者，上述中說明了使間隔e以2階段變化之例，但亦可採用使間隔e以3階段、4階段或其以上變化之構成。於該情形時，亦較佳為如下構成：切斷預定線之起始端側之長度方向之距離X-1較佳為5～15 mm，起始端側之間隔e1 於將尺寸b設為1時較佳為0.5，間隔e隨著朝向開封方向裏側而於1～1.75之範圍內逐漸變大。Although the example in which the interval e is changed in two steps has been described above, a configuration in which the interval e is changed in three steps, four steps, or more may be adopted. In this case, it is also preferable to have the following configuration: The distance X-1 in the length direction of the starting end side of the cut-off line is preferably 5 to 15 mm, and the interval e 1 at the starting end side is set to size b. The time is preferably 0.5, and the interval e gradually increases in a range of 1 to 1.75 as it goes toward the back side in the unsealing direction.
例如，如圖7所示，藉由自切斷預定線之起始端側至終端側，使圖2所示之間隔e逐漸變大，可使切斷預定線13a及13b呈曲線狀。間隔e於將尺寸b設為1時較佳為於0.5～1.75之範圍內變化。
[實施例]For example, as shown in FIG. 7, the interval e shown in FIG. 2 is gradually increased from the start end side to the end side of the planned cutting line, so that the planned cutting lines 13 a and 13 b can be curved. The interval e is preferably changed within a range of 0.5 to 1.75 when the dimension b is set to 1.
[Example]
以下，基於實施例，對本發明進一步詳細說明。再者，以下說明之實施例係表示本發明之代表性實施例之一例者，不應藉此而狹義地解釋本發明之範圍。說明按以下之順序進行。Hereinafter, the present invention will be described in further detail based on examples. In addition, the embodiment described below is an example of a representative embodiment of the present invention, and the scope of the present invention should not be narrowly interpreted by this. The explanation is performed in the following order.
1.對切割部之尺寸之研究
2.對切割部之間隔e之研究1. Study on the size of the cutting part
2. Study on the interval e of the cutting part
＜1.對切割部之尺寸之研究＞
準備5張光碟用塑膠外殼(長度124 mm、寬度142 mm、高度5 mm)(索尼股份有限公司製、商品名5NE1VJPS2)。又，作為包裝用膜，準備聚丙烯。＜ 1. Study on the size of cutting part ＞
Prepare five plastic disc cases (length 124 mm, width 142 mm, height 5 mm) (manufactured by Sony Corporation, trade name 5NE1VJPS2). Moreover, polypropylene was prepared as a packaging film.
首先，使用雷射打標機(松下設備SUNX股份有限公司製造)，於背面施有印刷之包裝用膜之端部切開2條成為開封開始部之寬度50mm之切口，以各切口為起點排列切割部，形成2條間隔逐漸擴大之切斷預定線。First, a laser marking machine (manufactured by Panasonic Equipment SUNX Co., Ltd.) was used to cut two 50 mm wide incisions at the end of the packaging film with the printed film on the back side to form the unsealing start portion. Part, forming two planned cut lines with gradually increasing intervals.
繼而，使用雷射打標機(松下設備SUNX股份有限公司製造)，將5張上述塑料外殼整個用包裝用膜包裝，藉由將包裝用膜之端部重疊之部分熱熔接，而獲得收縮包裝體。Then, a laser marking machine (manufactured by Panasonic Equipment SUNX Co., Ltd.) was used to pack the entire five plastic casings with a packaging film, and heat-welded the overlapping portions of the packaging film to obtain a shrink-wrapped package. body.
將第1切割部之尺寸a設為3.0mm，將第2切割部之尺寸b設為1.0 mm，使圖2之間隔c、間隔e變化，研究包裝之開封性。
再者，開封性之評價按以下之基準進行。
＜評價方法＞
A撕開效果非常好(切割部按照切割預定線連續撕開)
B撕開效果較好(不經由切割部撕開之部位很少，但沿切斷預定線撕開)
C撕開(不經由切割部撕開之部位較少，但沿切斷預定線之方向撕開)
D撕開有點困難(於切斷預定線之中途朝其他方向裂開，但大致於切斷預定線之方向撕開)
E難以撕開(於切斷預定線之中途朝其他方向裂開，未按照切斷預定線撕開)The size a of the first cutting portion was set to 3.0 mm, and the size b of the second cutting portion was set to 1.0 mm. The interval c and the interval e in FIG. 2 were changed, and the openability of the package was examined.
The evaluation of the openability was performed based on the following criteria.
＜ Evaluation method ＞
A tearing effect is very good (the cutting part tears continuously according to the planned cutting line)
B tear effect is better (few parts do not tear through the cutting part, but tear along the planned cutting line)
C tearing (fewer parts are not torn through the cutting part, but tearing in the direction of the intended cutting line)
D It is a bit difficult to tear (split in other directions in the middle of cutting the planned line, but roughly in the direction of cutting the planned line)
E Difficult to tear (split in other directions in the middle of the planned cutting line, not torn in accordance with the planned cutting line)
於表1表示開封性之研究結果。又，作為例子，於圖8表示實施例6之切割部之放大圖，於圖9表示比較例6之切割部之擴大圖。
再者，表1之比較例4～7中間隔c為負值。此係表示於圖2中相鄰之切割部22之第1切割線22a之端部位於較第2切割線21b之延長線更外側，第2切割線21b之延長線與相鄰之切割部22之第1切割線22a不相交之狀態。因此，以負值表示自第2切割線21b之延長線與相鄰之切割部22之第1切割線22a之延長線之交點至第2切割線21b之前端的間隔。Table 1 shows the results of the study on the openability. As an example, an enlarged view of the cutting portion of Example 6 is shown in FIG. 8, and an enlarged view of the cutting portion of Comparative Example 6 is shown in FIG. 9.
In addition, in Comparative Examples 4 to 7 of Table 1, the interval c is a negative value. This is shown in FIG. 2. The end of the first cutting line 22 a of the adjacent cutting portion 22 is located more outward than the extension of the second cutting line 21 b. The extension of the second cutting line 21 b is adjacent to the adjacent cutting portion 22. The state where the first cutting lines 22a do not intersect. Therefore, the interval from the intersection of the extension line of the second cutting line 21b and the extension line of the first cutting line 22a of the adjacent cutting portion 22 to the front end of the second cutting line 21b is represented by a negative value.
[表1]
根據表1及圖8，可知於間隔c大於0之實施例1～8中，可自切割部朝相鄰之切割部大致連續撕開膜，開封性較好。
又，根據表1之實施例9、比較例1～3，可知於間隔c為0之情形時，只要間隔e較窄即可於切斷預定線之方向開封，但隨著間隔e擴大會朝與切斷預定線不同之方向撕開，開封性變差。認為其原因在於，間隔e越窄，越可抑制裂縫向切割部21與相鄰之切割部22之間之左右方向裂開。
進而，根據表1及圖9，可知間隔c為負值之比較例4～7之開封性較差。認為其原因在於，若較相鄰之切割部22之第1切割線22a略微向內側裂開，則相鄰之切割部22之第1切割線22a無法完全阻止裂縫。According to Table 1 and FIG. 8, it can be seen that in Examples 1 to 8 in which the interval c is greater than 0, the film can be roughly torn from the cutting portion to the adjacent cutting portion, and the opening performance is good.
In addition, according to Example 9 and Comparative Examples 1 to 3 in Table 1, it can be seen that when the interval c is 0, as long as the interval e is narrow, the seal can be opened in the direction of cutting the predetermined line. Tearing in a direction different from the intended cutting line results in poor openability. The reason is considered that the narrower the interval e, the more the cracks can be prevented from cracking in the left-right direction between the cutting portion 21 and the adjacent cutting portion 22.
Furthermore, according to Table 1 and FIG. 9, it can be seen that Comparative Examples 4 to 7 in which the interval c is a negative value have poor sealing properties. The reason is considered to be that if the first cutting line 22a of the adjacent cutting portion 22 splits slightly inward, the first cutting line 22a of the adjacent cutting portion 22 cannot completely prevent cracks.
＜2.對切割部之間隔e之研究＞
除了如圖5所示於切斷預定線之中途使切割部之間隔e變化以外，還可利用與上述1.所示之包裝方法同樣之方法獲得收縮包裝體。
於各實施例中，將第1切割部之尺寸a統一為3.0 mm，將第2切割部之尺寸b統一為1.0 mm，將間隔c統一為1.0 mm。將切斷預定線之長邊方向之距離X設定為98 mm，且將切斷預定線於長度方向上分成2部分、分成3部分或分成4部分，自切斷預定線之起始端部起設為X-1、X-2、X-3、X-4。又，將切斷預定線之起始端部X-1之間隔e1
設為0.5 mm，之後以間隔e逐漸擴大之方式設定為e2
、e3
、e4
。
對表2所示之實施例10～18研究包裝之開封性，均可實現良好之開封性。＜ 2. Study on the interval e of the cutting section ＞
A shrink-wrapped body can be obtained by the same method as the packaging method shown in 1. above, except that the interval e of the cutting portion is changed in the course of cutting the predetermined line as shown in FIG. 5.
In each embodiment, the size a of the first cutting portion is unified to 3.0 mm, the size b of the second cutting portion is unified to 1.0 mm, and the interval c is unified to 1.0 mm. Set the distance X in the longitudinal direction of the planned cutting line to 98 mm, and divide the planned cutting line into 2 parts, 3 parts, or 4 parts in the longitudinal direction, and set from the starting end of the planned cutting line. X-1, X-2, X-3, X-4. Further, the interval e 1 of the starting end portion X-1 of the planned cutting line is set to 0.5 mm, and thereafter, the interval e is gradually set to e 2 , e 3 , and e 4 .
With regard to the unsealing properties of the packages of Examples 10 to 18 shown in Table 2, good unsealing properties were achieved.
