With the frequent use and universality of plastic packaging bags, we all pay special attention to the composition of plastic packaging bags? Which can put food and which can't? Let's talk about the composition of plastic packaging bags with you?

一、PVDC涂覆薄類的塑料包裝袋組：PVDC聚偏氯乙烯樹脂,常作為復(fù)合物質(zhì)或單體物質(zhì)及共擠薄膜片，PVDC涂覆薄膜是運用聚丙烯、聚對苯二甲酸乙二醇脂等作為基材的。純的PVDC軟化溫度高，且與其分化溫度挨近，又與通常增塑劑相溶性差，故加熱成型艱難而難以直接運用。實際上運用的PVDC薄膜多為偏氯乙烯和氯乙烯的共聚物，以及和丙烯酸甲脂共聚制成的隔絕性格外好的薄膜。

1、 PVDC coated thin plastic packaging bag group: PVDC polyvinylidene chloride resin, often as a composite or monomer material and co extruded film sheet, PVDC coated film is based on polypropylene, polyethylene terephthalate, etc. Pure PVDC has high softening temperature, close to its differentiation temperature, and poor solubility with common plasticizers, so it is difficult to use directly. In fact, most PVDC films used are copolymers of vinylidene chloride and vinyl chloride, as well as films made by copolymerization with acrylic acid methyl ester.

二、尼龍類塑料包裝袋：尼龍類塑料包裝袋的特點是隔絕性不隨濕度的上升而降低?，F(xiàn)在所用的尼龍類塑料包裝袋是一種從間二甲基胺和已二酸縮聚而成的尼龍MXD6，有杰出的透明性和耐穿刺性，經(jīng)常被用于隔絕性要求很高的食物軟包裝。

2、 Nylon plastic packaging bags: nylon plastic packaging bags are characterized by insulation not decreasing with the increase of humidity. Now the nylon plastic packaging bag is a kind of nylon MXD6 condensed from m-dimethylamine and adipic acid, which has outstanding transparency and puncture resistance, and is often used in the soft packaging of food with high isolation requirements.
