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
技术领域
本发明涉及一种塑料膜,用于包装产品,尤其用于包装方块状产品,例如汤料块,其中塑料膜由聚烯烃,优选地由PE或者PP组成。
背景技术
由EP-A-0870695公知一种这类型的塑料膜。
此外,EP-A-0891930说明了一种类似的塑料膜。
为上述目的迄今大多采用铝-纸复合物,这种复合物不论是生产还是回收利用都存在困难。
发明内容
本发明的目的在于,提出一种很适用于上述用途的塑料膜。
根据本发明,如此地达到上述目的,提供一种塑料膜,用于包装产品,特别是方块状产品,例如汤料方块,其中塑料膜由一种聚烯烃组成,优选地由PE或PP组成,且所述塑料膜的至少一侧设有封合层,其特征在于,在所述塑料膜外侧设有封合层,该封合层以1至15g/m2的密度涂覆。
这里还通过简单地折合和热压达到可靠地封闭的包装。
这里,根据本发明的一个优选的扩展设置热火漆作为封闭层。
可以特别简单地把所述热火漆涂覆在塑料膜上。
本发明的一个优选的进一步扩展在于,塑料膜由OPP或OPE组成。
由这两种材料制造的塑料膜都能够良好地被折叠。
如果按照本发明的另一个扩展塑料膜的厚度是10至100μm,合时特别有利的。
这样厚度范围的塑料膜证明是非常有利的。
本发明的另一个优选的扩展的特征在于,所述塑料膜至少一侧金属化。
如果按照本发明塑料膜的外侧设胶合层或封合层,在此证明是特别有优越性的。
如果按照本发明的一个进一步扩展,造型地安排至少设在塑料膜的外侧的胶合层或封合层,证明是特别地有利的。
如果在塑料膜上设有彩色涂层也是非常有利的。
根据本发明的一个进一步扩展所述彩色涂层可以设有罩漆。
由此使颜色受到附加的保护。
根据本发明的一个进一步扩展,如果用印刷法涂覆罩漆是特别有利的。
根据本发明的一个进一步扩展,所述罩漆可以用0.1至10.0g/m2的密度涂覆。
附图说明
下面参照附图所示的两个实施例说明本发明。
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。
具体实施方式
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。
