Abstract

本发明涉及饮料包装技术，特别是牛奶等饮料或其它液体物的灌装包装时一种饮料包装盒包材纵向密封新工艺。其特征是将纸基材在还没有涂复塑料膜之前，先将纸割开一条6-16mm宽的缝，然后再在纸上复合塑料膜与铝箔，再在缝的中心线位置割开，使缝的两边都有3-8mm宽的塑料边；将两条塑料边的一边在下面，另一边在上面叠合后，加热压焊形成有可靠密封的纵向密封包装盒包材；所说的纸基材割开一条缝的宽度是10-12mm。改变了以往多层复合工艺，先开缝后复合，确保了包材的纵向密封，省去昂贵的密封条和用专门做密封条的设备，也省去专门用来贴密封条的机构。

Description

一种饮料包装盒包材纵向密封新工艺
技术领域
本发明涉及饮料包装技术，特别是牛奶等饮料或其它液体物的灌装包装时一种饮料包装盒包材纵向密封新工艺。
背景技术
以往的饮料包装盒，一般都是以塑料、纸、铝箔、塑料或经塑料、纸、塑料各自经多层复合后作为包材来制作包装盒，包材在折合成砖型包或屋顶包型时，纵向接缝必须保证密封，其纵向接缝内侧必须贴上用另外塑料做成的密封条，否则在接缝处有露纸的地方会渗漏包装液。现有贴密封条的工艺有以下两点缺陷：一是需要另外做密封条，这种密封条的价格十分昂贵，是普通塑料价格的十多倍，还要用专用的设备来做密封条；二是需要专门用来贴密封条的设备加工，其工艺十分复杂，即使这样制作也难以保证百分之百密封。因此，包材纵向密封是制作包装盒的关键问题。
发明内容
本发明的目的是针对上述缺陷，提供一种饮料包装盒包材纵向密封新工艺。
本发明的技术方案是一种饮料包装盒包材纵向密封新工艺，包装盒包材采用以纸作为基材，其纸的两面多层复合有塑料膜与铝箔作为包材或以纸作基材其两面复合塑料膜作为包材，包材折合成两头开口的砖型或屋顶包型时需纵向密封，其特征是：
A、将纸基材在还没有涂复塑料膜之前，先将纸割开一条6-16mm宽的缝，然后再在纸上复合塑料膜与铝箔，再在缝的中心线位置割开，使缝的两边都有3-8mm宽的塑料密封边；
B、将两条塑料密封边的一边在下面，另一边在上面叠合后，加热压焊形成有可靠密封的纵向密封包装盒包材。
所说的纸基材割开一条缝的宽度是10-12mm。
本发明的优点是改变了以往多层复合工艺，先开缝后复合，在末涂复第一层塑料之前，先在复合机上将纸基材割开一条缝，缝的宽度比原工艺的密封条宽一些，然后再将纸的两面复合以塑料、铝箔等，而后沿这条缝的中心线割开包材，有5mm左右宽塑料边，包材折合后进行接缝时，将对边压在这条边上，然后在搭接的地方依次加热，把两塑料边压焊在一起，确保了包材的纵向密封，从而也保证了包材折合成包装盒后的纵向可靠密封。
附图说明
图1是原有包材的结构示意图。
图2是图1的左视图。
图3是本发明已带密封边的包材结构示意图。
具体实施方式
以下结合附图进一步说明本发明的实施例。
参照图1、图2，1-包材、2-纵向缝隙、3-接缝形式、4-密封条。如图示，这是原有用密封条纵向密封的情况。原来的包装盒包材横截面为长方形或正方形且两头开口，经折合后呈砖型或屋顶包型包装盒。其纵向接缝2的接缝形式3，其内侧整个纵向必须贴上用另外塑料做成的密封条4加热压焊进行密封，否则，在接缝处如有露纸的地方就会渗漏包装液。
参照图3，是本发明的密封工艺示意图。1-已带密封塑料边的包材、3接缝形式。本发明的创新之点是改变了原先多层复合包材的复合工艺，在末涂复第一层塑料之前，先在复合机上将纸割开一条缝，缝的宽度比原来密封条的宽度大一些，然后将纸的两面复以塑料、铝箔等，再沿这条缝的中心线割开包材使包材在缝的两边都有5mm宽且中间没有纸只有塑料和铝箔的边。包材折合进行接缝时，将一边压在另一边上，使塑料边处在里面而另一边处在多点面，然后在搭接的地方依次加热，把塑料边压焊地另一边上，得到一条密封可靠整齐美观的纵向密封区域。省去昂贵的密封条和用专门做密封条的设备，也省去专门用来贴密封条的机构。
