　　1、高压聚乙烯塑料袋

　　1. High pressure polyethylene plastic bag

　　高压聚乙烯又称低密度聚乙烯（LDPE），程半透明状态，塑料购物袋制品透明性一般较低压聚乙烯好。其主要用途有3类：

　　High pressure polyethylene, also known as low-density polyethylene (LDPE), is in a semi transparent state. Plastic shopping bag products generally have better transparency than low-pressure polyethylene. There are three main uses of it:

　　A、食品包装：糕点、糖果、炒货、饼干、奶粉、盐、茶叶等；

　　A、 Food packaging: pastries, candies, stir fried goods, biscuits, milk powder, salt, tea, etc;

　　B、纤维品包装：衬衫、服装、针棉品、化纤制品；

　　B、 Fiber packaging: shirts, clothing, needle cotton products, synthetic fiber products;

　　C、日化用品包装.

　　C、 Packaging for daily chemical products

　　2、低压聚乙烯塑料袋低压聚乙烯又称高密度聚乙烯（HDPE），由于其有较高的结晶度，透明度不好，一般呈半透明状态，透明度较HDPE高压聚乙烯塑 料袋制品差。其主要用途有4类：

　　2. Low pressure polyethylene plastic bags, also known as high-density polyethylene (HDPE), have high crystallinity and poor transparency. They are generally semi transparent and have lower transparency than HDPE high-pressure polyethylene plastic bag products. Its main uses are divided into four categories:

　　A、垃圾袋、菌种袋；B、方便袋、塑料购物袋、手提袋、背心袋；C、保鲜袋；

　　A、 Garbage bags, bacterial bags; B、 Convenience bags, plastic shopping bags, tote bags, vest bags; C、 freshness protection package;

　　D、编织袋内袋

　　D、 Woven bag inner bag

　　3、聚丙烯塑料袋

　　3. Polypropylene plastic bag

　　聚丙烯塑料袋的聚丙烯相对于聚乙烯，其结晶能了会弱化需要，尤其是无规聚丙烯，结晶性弱，其塑料袋制品的透明度很想对 高很多。

　　Compared to polyethylene, the crystallization energy of polypropylene in polypropylene plastic bags will weaken, especially for random polypropylene, which has weak crystallinity and much higher transparency in plastic bag products.

　　主要用于包装纺织品、针棉品、服装、衬衫等.

　　Mainly used for packaging textiles, needle cotton products, clothing, shirts, etc

　　前三者塑料袋由于本身物质结构的非极性原因，不易染色或印刷，需要进行表面印刷处理。

　　The first three types of plastic bags, due to their non-polar material structure, are not easy to dye or print and require surface printing treatment.

　　4、聚氯乙烯塑料袋

　　4. Polyvinyl chloride plastic bag

　　聚氯乙烯塑料袋，由聚氯乙烯树脂吹塑加工而来，相对于前三者塑料袋，其物质结构中引入了氯元素这种物质，使得其结晶效果很弱，制品的透明度较高，同时由于氯元素的加入，使得材料本身带有一定极性，容易印刷着色。其主要用途为2个方面：

　　Polyvinyl chloride plastic bags are blow molded from polyvinyl chloride resin. Compared with the previous three types of plastic bags, the material structure introduces chlorine element, which makes its crystallization effect weak and the transparency of the product high. At the same time, due to the addition of chlorine element, the material itself has a certain polarity, making it easy to print and color. Its main purposes are twofold:

　　A、礼品袋；B、箱包袋、针棉品包装袋、化妆品包装袋；

　　A、 Gift bag; B、 Luggage bags, needle cotton packaging bags, cosmetics packaging bags;

　　5、可降解塑料袋可降解塑料袋是各类生物降解塑料袋的简称，随着科技的发展，各类可替代传统PE塑料的材料出现，包括PLA，PHAs，PBA，PBS等高分子材料。均可替代传统PE塑料袋。塑料袋厂家定做V信：408039448，现在应用已经较为广泛：购物袋，门店购物袋，连卷保鲜袋，地膜等在国内均有大规模应用的范例。目前常见的生物降解塑料主要有聚乳酸（PLA）、聚己内酯（PCL）、局二酸丁二醇酯（PBS）、聚羟基丁酸酯（PHB）和聚碳酸亚内酯（PPC）、聚对苯二甲酸-己二酸丁二酯（PBAT）等。降解塑料购物袋使用现状塑料污染治理政策规定，不可降解塑料购物袋属于禁止使用的塑料制品名录范畴，降解塑料购物袋是其替代产品之一。但是通过此次采样，发现降解塑料购物袋产品使用现状不容乐观，基本现状如下：成本较高。降解塑料购物袋售价多在0.8-1.8元/个，和普通塑料购物袋相比翻倍。主要是由于降解塑料原材料成本较高，现PLA原料售价为1.5-3万元/吨，PBAT原料售价为1.4-2.5万元/吨，而PE原料售价仅为0.8-1.0万元/吨。

　　5. Degradable plastic bags are environmentally friendly. Degradable plastic bags are the abbreviation for various types of biodegradable plastic bags. With the development of technology, various materials that can replace traditional PE plastics have emerged, including PLA, PHAs, PBA, PBS and other polymer materials. Can replace traditional PE plastic bags. Environmentally friendly plastic bag manufacturer customized V letter: 408039448, now widely used: supermarket shopping bags, brand store shopping bags, continuous roll fresh-keeping bags, plastic film and other large-scale application examples in China. The commonly used biodegradable plastics currently include polylactic acid (PLA), polycaprolactone (PCL), polybutylene succinate (PBS), polyhydroxybutyrate (PHB), polycarbonate (PPC), and polybutylene terephthalate adipate (PBAT). According to the national plastic pollution control policy, non degradable plastic shopping bags belong to the list of plastic products prohibited by the country, and degradable plastic shopping bags are one of their alternative products. However, through this sampling, it was found that the current usage status of biodegradable plastic shopping bags is not optimistic, and the basic situation is as follows: the price and cost are relatively high. The selling price of biodegradable plastic shopping bags is mostly between 0.8-1.8 yuan per bag, which is twice the price compared to ordinary plastic shopping bags. Mainly due to the high cost of biodegradable plastic raw materials, the current selling price of PLA raw materials is 15000-30000 yuan/ton, PBAT raw materials is 14000-25000 yuan/ton, and PE raw materials is only 8000-10000 yuan/ton.
