復(fù)合卷膜塑料袋的材質(zhì)及用途

來源:http://m.ssxx10.com/ 日期:2023-10-13

復(fù)合袋的材質(zhì)是聚對苯二甲酸乙二醇酯與高壓聚乙烯,習(xí)慣簡寫為PET/PE復(fù)合袋,其具有透明度高,阻氧性好的特點(diǎn),所以特別適合象面包和蛋糕類食品的充氣包裝。而且由于這種復(fù)合膜的耐熱和耐寒性也都很好,也可以作為速凍食品和蒸煮食品的包裝袋。

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.

復(fù)合膜的材質(zhì)是雙向拉伸聚丙烯與未拉伸聚丙烯,習(xí)慣稱為OPP/CPP復(fù)合膜袋,在所有的復(fù)合膜中,這種復(fù)合膜是透明度的。與單膜塑料袋相比,同樣厚度下,成本要高于單膜塑料袋,但手感要好于單膜袋;又由于這種膜的阻濕性能好,用在食品方面,主要用于包裝一些干燥食品和快餐食品,如餅干,方便面等。缺點(diǎn)是耐高溫和耐寒性能差,不宜包裝冷藏和高溫食品。
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.

復(fù)合袋是由雙向拉伸聚丙烯與高壓聚乙烯復(fù)合膜袋構(gòu)成,一般簡寫為OPP/PE復(fù)合袋,這種復(fù)合袋的阻氣和阻濕性非常好,所以特別適合象綠茶這樣產(chǎn)品的包裝,它的耐油性效果也不錯,所以熟食品和一些油制品也用這種復(fù)合袋包裝。
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.
