塑料袋原料知识你知道多少？

What do you know about plastic bag raw materials?

塑料袋，可谓是一项令人又爱又恨的发明，因为塑料袋的使用为人们提供了非常大的便利，但同时，塑料袋又是污染环境的一大杀器，因为它一旦生产出来就很难自然降解。塑料袋到底是怎么生产的呢？接下来塑料袋生产厂家就给大家介绍一下它的原料知识。

Plastic bags can be described as a love hate invention, because the use of plastic bags provides great convenience for people, but at the same time, plastic bags are a big killer of polluting the environment, because once they are produced, they are difficult to degrade naturally. How are plastic bags produced? Next, the plastic bag manufacturer will introduce its raw material knowledge to you.

塑料袋的原材料是塑料，塑料是从石油或煤炭中提取的化学石油产品，它是一种很轻的物质，用很低的温度加热就能使它变软，随心所欲地做成各种形状的东西。用它制成的塑料袋色彩鲜艳，重量轻，不怕摔，经济耐用，它的使用不仅给人们的生活带来了诸多方便，也很大程度上推动了工业的发展。

The raw material of plastic bag is plastic. Plastic is a chemical petroleum product extracted from oil or coal. It is a very light substance. Heating at a very low temperature can make it soft and make things of various shapes at will. The plastic bag made of it has bright color, light weight, no fear of falling, economy and durability. Its use not only brings a lot of convenience to people's life, but also promotes the development of industry to a great extent.

塑料袋在制造生产过程中往往要加入各种物质。其中高分子聚合物是塑料的主要成分。此外，为了改进塑料的性能，还要在聚合物中添加各种辅助材料。合成树脂在塑料中的含量一般在40～100，树脂的性质决定了塑料的性质。填充剂可以提高塑料的强度和耐热性能，并降低成本。增塑剂可增加塑料的可塑性和柔软性，降低脆性，使塑料易于加工成型。

Various substances are often added to plastic bags in the manufacturing process. High polymer is the main component of plastics. In addition, in order to improve the properties of plastics, various auxiliary materials should be added to the polymer. The content of synthetic resin in plastics is generally 40 ~ 100. The properties of resin determine the properties of plastics. Fillers can improve the strength and heat resistance of plastics and reduce costs. Plasticizers can increase the plasticity and softness of plastics, reduce brittleness and make plastics easy to process and shape.

由于塑料袋所造成的环境危害是巨大的，世界上各个都陆陆续续地颁布了相关的塑料袋管理法令，也在其中。限塑令中规定了塑料袋的生产标准，禁止生产销售厚度小于0.025毫米的超薄塑料袋。塑料袋的厚度是以丝为单位，一丝就是0.01毫米。我们日常生活中常用的塑料袋一般是双层5丝、单层12丝和双层7丝，标准要求是塑料袋的厚度是双层5丝的厚度，若小于这个厚度则为劣质的不合格塑料袋。

As the environmental harm caused by plastic bags is huge, all countries in the world have successively promulgated relevant plastic bag management laws, including China. The plastic restriction order stipulates the production standards of plastic bags and prohibits the production and sales of ultra-thin plastic bags with a thickness of less than 0.025 mm. The thickness of the plastic bag is in silk, and one silk is 0.01 mm. The commonly used plastic bags in our daily life are generally double-layer 5 silk, single-layer 12 silk and double-layer 7 silk. The national standard requires that the thickness of the plastic bag is the thickness of double-layer 5 silk. If it is less than this thickness, it is an inferior unqualified plastic bag.

了解了塑料袋的相关原料知识，日后若是购买塑料袋，一定要选购符合标准的质量合格的塑料袋，塑料袋生产厂家也应该遵守塑料袋生产标准，生产合格的塑料袋。

After knowing the relevant raw material knowledge of plastic bags, if you buy plastic bags in the future, you must buy qualified plastic bags that meet the standards. Plastic bag manufacturers should also abide by the plastic bag production standards and produce qualified plastic bags.
