复合袋的材质是聚对苯二甲酸乙二醇酯与高压聚乙烯,习惯简写为PET/PE复合袋,其具有透明度高,阻氧性好的特点,所以特别适合象面包和蛋糕类食品的充气包装。而且由于这种复合膜的耐热和耐寒性也都很好,也可以作为速冻食品和蒸煮食品的包装袋。

The material of the composite bag is polyethylene terephthalate and high-pressure polyethylene, commonly abbreviated as PET/PE composite bag. It has the characteristics of high transparency and good oxygen resistance, making it particularly suitable for inflatable packaging of foods such as bread and cake. Moreover, due to its excellent heat and cold resistance, this composite film can also be used as a packaging bag for frozen and steamed foods.

复合膜的材质是双向拉伸聚丙烯与未拉伸聚丙烯,习惯称为OPP/CPP复合膜袋,在所有的复合膜中,这种复合膜是透明度最高的。与单膜塑料袋相比,同样厚度下,成本要高于单膜塑料袋,但手感要好于单膜袋;又由于这种膜的阻湿性能好,用在食品方面,主要用于包装一些干燥食品和快餐食品,如饼干,方便面等。缺点是耐高温和耐寒性能差,不宜包装冷藏和高温灭菌食品。

The material of the composite film is biaxially stretched polypropylene and non stretched polypropylene, commonly known as OPP/CPP composite film bags. Among all composite films, this composite film has the highest transparency. Compared with single film plastic bags, under the same thickness, the cost is higher than that of single film plastic bags, but the feel is better than that of single film bags; Due to its good moisture resistance, this film is mainly used for packaging dry and fast food products, such as biscuits and instant noodles, when used in food. The disadvantage is poor resistance to high temperature and cold, making it unsuitable for packaging refrigerated and high-temperature sterilized food.

复合袋是由双向拉伸聚丙烯与高压聚乙烯复合膜袋构成,一般简写为OPP/PE复合袋,这种复合袋的阻气和阻湿性非常好,所以特别适合象绿茶这样产品的包装,它的耐油性效果也不错,所以熟食品和一些油制品也用这种复合袋包装。
Composite bags are composed of biaxially stretched polypropylene and high-pressure polyethylene composite film bags, commonly abbreviated as OPP/PE composite bags. This type of composite bag has excellent air and moisture resistance, making it particularly suitable for packaging products like green tea. Its oil resistance effect is also good, so cooked food and some oil products are also packaged with this composite bag.
