纯原料和再生原料制作的塑料袋有哪些不一样?

发布日期:2021-09-09 作者:www.jnsuliao.com 点击:

其实差别就出在原料上,塑料原料有两个来源:纯原料和再生原料,纯原料价格高于再生原料,所以纯原料生产出来的产品就比再生原料生产出的产品高,辨别塑料原料好坏是每个生产商所掌握的基本能力之一,下面就简单介绍这两种原料的不同
In fact, the difference lies in the raw materials. There are two sources of plastic raw materials: pure raw materials and recycled raw materials. The price of pure raw materials is higher than that of recycled raw materials, so the products produced by pure raw materials are higher than those produced by recycled raw materials. Distinguishing the quality of plastic raw materials is one of the basic abilities mastered by each manufacturer. Here is a brief introduction to the differences between the two raw materials
1、纯原料
1. Pure raw material
纯原料来源于从石油提炼出来的,没有经过任何的再加工,其特点是颗粒为乳白色、晶莹透明,没有任何杂质,物理特性特别好,非常容易加工,我国使用的纯原料有两个途径,一是国内各大石化公司,二是通过进口。纯原料生产出来的产品一般无色无异味,有较好的光泽,弹性好,手感非常柔软,主要是卫生安全,纯原料一般用于食品袋的、连卷袋等食品相关包装袋

Pure raw materials are extracted from petroleum without any reprocessing. Its characteristics are that the particles are milky white, crystal clear, free of any impurities, especially good physical properties and very easy to process. There are two ways to use pure raw materials in China, one is the major petrochemical companies in China, and the other is through import. The products produced from pure raw materials are generally colorless and odorless, with good luster, good elasticity and very soft feel, mainly for health and safety. Pure raw materials are generally used in food bags, roll bags and other food related packaging bags
2、再生原料
2. Recycled raw materials
再生原料来源非常广泛,也非常杂,主要来源为生产方便袋的废料、生活废塑料、各种包装袋等等,这些废料通过回收后进行分拣,然后再切割、高温熔化后做成塑料颗粒,由于回收的废料复杂多样,颜色各异,所以生产出的颗粒带有各种颜色,没有任何光泽,与纯原料颗粒相比有天壤之别,而且生产出来的产品不能卫生安全,产品而且都带有颜色,没有任何光泽,手感粗糙,一般用于生活日用和工业,不能用于食品包装。
The sources of recycled raw materials are very wide and miscellaneous. The main sources are the waste from the production of convenience bags, domestic waste plastics, various packaging bags, etc. these wastes are sorted after recycling, then cut and melted at high temperature to make plastic particles. Due to the complexity and diversity of recycled wastes and different colors, the produced particles have various colors and no luster, Compared with pure raw material particles, it is very different, and the products produced can not be hygienic and safe. The products have color, no luster and rough feel. They are generally used for daily life and industry, not for food packaging.
