　　1、高壓聚乙烯塑料袋

　　1. High pressure polyethylene plastic bag

　　高壓聚乙烯又稱低密度聚乙烯（LDPE），程半透明狀態(tài)，塑料購物袋制品透明性一般較低壓聚乙烯好。其主要用途有3類：

　　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、食品包裝：糕點、糖果、炒貨、餅干、奶粉、鹽、茶葉等；

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

　　B、纖維品包裝：襯衫、服裝、針棉品、化纖制品；

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

　　C、日化用品包裝.

　　C、 Packaging for daily chemical products

　　2、低壓聚乙烯塑料袋低壓聚乙烯又稱高密度聚乙烯（HDPE），由于其有較高的結(jié)晶度，透明度不好，一般呈半透明狀態(tài)，透明度較HDPE高壓聚乙烯塑 料袋制品差。其主要用途有4類：

　　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、菌種袋；B、方便袋、塑料購物袋、手提袋、背心袋；C、保鮮袋；

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

　　D、編織袋內(nèi)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對于聚乙烯，其結(jié)晶能了會弱化需要，尤其是無規(guī)聚丙烯，結(jié)晶性弱，其塑料袋制品的透明度很想對 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.

　　主要用于包裝紡織品、針棉品、服裝、襯衫等.

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

　　前三者塑料袋由于本身物質(zhì)結(jié)構(gòu)的非極性原因，不易染色或印刷，需要進(jìn)行表面印刷處理。

　　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，由聚氯乙烯樹脂吹塑加工而來，相對于前三者塑料袋，其物質(zhì)結(jié)構(gòu)中引入了氯元素這種物質(zhì)，使得其結(jié)晶效果很弱，制品的透明度較高，同時由于氯元素的加入，使得材料本身帶有一定極性，容易印刷著色。其主要用途為2個方面：

　　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、禮品袋；B、箱包袋、針棉品包裝袋、化妝品包裝袋；

　　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類生物降解塑料袋的簡稱，隨著科技的發(fā)展，各類可替代傳統(tǒng)PE塑料的材料出現(xiàn)，包括PLA，PHAs，PBA，PBS等高分子材料。均可替代傳統(tǒng)PE塑料袋。塑料袋廠家定做V信：408039448，現(xiàn)在應(yīng)用已經(jīng)較為廣泛：購物袋，門店購物袋，連卷保鮮袋，地膜等在國內(nèi)均有大規(guī)模應(yīng)用的范例。目前常見的生物降解塑料主要有聚乳酸（PLA）、聚己內(nèi)酯（PCL）、局二酸丁二醇酯（PBS）、聚羥基丁酸酯（PHB）和聚碳酸亞內(nèi)酯（PPC）、聚對苯二甲酸-己二酸丁二酯（PBAT）等。降解塑料購物袋使用現(xiàn)狀塑料污染治理政策規(guī)定，不可降解塑料購物袋屬于禁止使用的塑料制品名錄范疇，降解塑料購物袋是其替代產(chǎn)品之一。但是通過此次采樣，發(fā)現(xiàn)降解塑料購物袋產(chǎn)品使用現(xiàn)狀不容樂觀，基本現(xiàn)狀如下：成本較高。降解塑料購物袋售價多在0.8-1.8元/個，和普通塑料購物袋相比翻倍。主要是由于降解塑料原材料成本較高，現(xiàn)PLA原料售價為1.5-3萬元/噸，PBAT原料售價為1.4-2.5萬元/噸，而PE原料售價僅為0.8-1.0萬元/噸。

　　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.
