在包装工业发展的基础上,物品的包装也得到相应的发展。从简单纸包装,到单层塑料薄膜包装,发展到复合材料的广泛使用。复合膜能使包装内含物具有保湿、保香、美观、保鲜、避光、防渗透、延长货架期等特点,因而得到迅猛发展。

On the basis of the development of packaging industry, the packaging of goods has also been developed accordingly. From simple paper packaging, to single-layer plastic film packaging, to the extensive use of composite materials. The composite film can make the contents of the package have the characteristics of moisturizing, fragrance preserving, beauty preserving, fresh-keeping, light avoiding, impermeability, and extending the shelf life, so it has developed rapidly.

复合塑料包装袋比传统包装袋实用性要更好一些,防水性、耐热性都要远远超过普通包装袋。下面就让我们来看看复合包装袋的组成材料有什么吧。

Composite plastic packaging bags are more practical than traditional packaging bags, and their water resistance and heat resistance are far more than ordinary packaging bags. Now let's take a look at the constituent materials of composite packaging bags.

复合塑料包装袋是由两种或两种以上塑料原材料,经过一次或多次复合工艺而组合在一起,从而构成具有特定功能的塑料复合袋。一般可分为基层、功能层和热封层。基层主要起美观、印刷、阻湿等作用。如BOPP、BOPET、BOPA、MT、KOP、KPET等;功能层主要起阻隔、避光等作用,如VMPET、AL、EVOH、PVDC等;热封层与包装物品直接接触,起适应性、耐渗透性、良好的热封性,以及透明性、开口性等功能,如LDPE、LLDPE、MLLDPE、CPP、VMCPP、EVA、EAA、E-MAA、EMA、EBA等。

Composite plastic packaging bag is a plastic composite bag with specific functions, which is composed of two or more plastic raw materials through one or more composite processes. Generally, it can be divided into base course, functional layer and heat sealing layer. The base course mainly plays the role of aesthetics, printing, moisture resistance, etc. Such as BOPP, BOPET, BOPA, MT, Kop, kpet, etc; The function layer is mainly used to block and avoid light, such as VMPET, Al, EVOH, PVDC, etc; The heat sealing layer is in direct contact with the packaging, which has the functions of adaptability, permeability resistance, good heat sealing, transparency, openness and so on, such as LDPE, LLDPE, mLLDPE, CPP, VMCPP, EVA, EAA, e-maa, EMA, EBA, etc.


复合塑料包装袋所牵涉的原材料种类较多,性质各异,哪些塑料材料可以结合或不能结合,用什么东西黏合等,问题比较多而复杂,所以必须对塑胶袋原材料精心选择,方能获得理想的效果。推荐选择的原则如下:

There are many kinds of raw materials involved in composite plastic packaging bags, with different properties, which plastic materials can be combined or not, and what things are used to bond, etc. there are many and complex problems, so we must carefully select the raw materials of plastic bags in order to obtain the ideal effect.
