Abstract

一种塑料膜(1,41)用于包装产品,尤其用于包装最好是块状的产品,例如汤料块,其中,该塑料膜(1,41)由聚烯烃,最好是PE或PP组成。

Description

塑料膜
本发明涉及一种塑料膜，用于包装产品，尤其用于包装最好是方块状产品，如汤料块。
为了上述目的，到目前为止大都采用铝-纸复合体，它们不论在生产方面，还是在回收利用方面都难以实行。
本发明的目的在于，提出一种很适合上述用途的塑料膜。
按照本发明，上述目的将通过以下方式达到，即该塑料膜由一种聚烯烃，最好是PE或PP组成，它可容易拆开。
借助易拆开性，该包装膜可可精确适配所要求的形状。
本发明的其它优先实施形式在于，塑料膜由0PP或OPE组成。
由两种材料组成的塑料膜尤其易于折叠。
按照本发明的另一实施形式，塑料膜厚度为0至100μm时，被证明是尤其具有优点的。
在该厚度范围内的塑料膜被证明是尤其适合的。
本发明的另一优先实施形式的特征为，该塑料膜的至少一侧被金属化。
此外，按照本发明的实施形式，该塑料膜至少一侧设有胶合层或封合层。
因此，使用该塑料膜的包装是密封的。
按照本发明，当封合层的密度为至15g/m2时，被证明是非常具有优点的。
本发明的另一优先实施形式是，作为封合层采用热火漆。
按照本发明，当采用压敏胶作为胶合层时，被证明是非常具有优点的。
由此，包装的密封可尤其简单地实现。
在此被证明尤其具有优点的是，按照本发明，塑料膜的外侧设有胶合层或封合层。
如果按照本发明的另一实施形式，把至少塑料膜外侧上的胶合层或封合层造型地安排，被证明是尤其适合的。
在此，胶合层或封合层仅放在需要它们的地方。
同样适合的是，塑料膜上设有漆层。
按照本发明的另一实施形式，漆层设有保护漆。
由此，颜色受到额外保护。
在此尤其适合的是，按照本发明的另一实施形式，保护漆用压力法被涂覆。
按照本发明能够的另一实施形式，保护漆的密度为0.1至10.0g/m2。
下面将参照图中所示两个实施例对本发明说明。
图1.塑料膜的截面图；
图2.塑料膜的管形截面；
图3.用图1或2所示塑料膜包装的汤料块；
图4.经过另一种塑料膜的截面；
图5.图4中塑料膜的管形截面；
图6.在图4和5所示塑料膜内的汤料块。
在图1中，用1表示由OPE制成的塑料膜。OPE膜1的一侧涂覆有热火漆2，而另一侧具有一层彩色印刷3。
彩色印刷3此外设有一层套印漆4。
塑料膜1的一侧还要金属化(层5)。
塑料膜1的一段沿纵向缝21形成一段软管20。如图3所示，为形成汤料块包装，软管20的一端首先被叠合并随后装入待装入料。此后，塑料膜1的软管段的另一端同样被叠合。由于塑料膜良好的可叠合性，叠合的楔角很小。因此，即使在没有附加的封闭情况下，也能获得密封包装。
除软管式包装外，处理块状待装入料时，也可借助一段平面的膜包起它们。
对于特别敏感的待装入料，在两种实施形式中都可以把各个叠合的末端段彼此封合。
除OPE外，也可采用OPP或PP作为塑料膜材料。该膜的厚度为约50μm，不过，可根据需要在10至100μm之间变化。
在图4所示实施例中，用41表示另一由OPE制成的塑料膜。OPE膜41在一侧涂覆有压力敏感的粘合物42。在该粘合物下方设有彩色印刷43，它还有一层压制漆44。
在此，胶合层可造型地涂覆，这对内侧及对外侧都有意义。
附加于，或者取代彩色印刷34，还可以单侧地金属化塑料膜41(层45)。
塑料膜41的一段相对于上面的实施例沿一纵向缝21形成一段软管50。如图5所示，为形成汤料块包装，软管50的一端首先被叠合并随后装入待装入料。此后，塑料膜41的软管段的另一端同样被叠合。由于塑料膜良好的可叠合性，叠合的楔角很小。此外，楔角借助胶合层紧贴在包装的外侧。对于相应的层，也可以封合。
除软管式包装外，处理块状待装入料时，也可借助一段平面的膜包起它们。
除OPE外，也可采用OPP或PP作为塑料膜材料。该膜的厚度为约50μm，不过，可根据需要在10至100μm之间变化。
