可降解塑料与全降解塑料的区别

如今越来越多的客户和消费者开始注重塑料袋的环保性，开始了解绿色降解塑料袋，但其实降解可分为“可降解”和“全降解”两种。如何区分二者呢？可降解颗粒生产厂家为您讲解。

Nowadays, more and more customers and consumers begin to pay attention to the environmental protection of plastic bags and begin to understand the green degradable plastic bags. However, degradation can be divided into "degradable" and "fully degradable". How to distinguish the two? The manufacturer of degradable particles will explain it to you.

可降解塑料袋是指在塑料生产过程中加入一定量的添加剂使其稳定性下降，比较容易在自然环境中降解。这种塑料制品虽然可以降解，但是并不能完全降解。并且这种石油基制品是通过化学反应而不是微生物有机分解，所以并不能完全分解成有机物，相反会分解成微小的碎片进入环境，这些微塑料被动物摄入进入食物链，可通过生物圈回到人类社会引起重大问题。

The degradable plastic bag means that a certain amount of additives are added in the plastic production process to reduce its stability, and it is easier to degrade in the natural environment. Although this plastic product can be degraded, it cannot be completely degraded. Moreover, this petroleum based product is decomposed organically through chemical reaction rather than microorganism, so it cannot be completely decomposed into organic matter, instead, it will be decomposed into tiny fragments and enter the environment. These micro plastics are ingested by animals and enter the food chain, which can cause major problems through the biosphere back to human society.

全降解塑料袋是指塑料袋可以全部降解成水与二氧化碳。这种全降解材料的主要来源是由玉米、木薯等经过加工变成乳酸，也就是PLA，其具有良好的生物可降解性，使用后能被自然界中微生物在特定条件下完全降解，终生成二氧化碳和水，不污染环境，对保护环境非常有利，是公认的环境友好材料。

Fully degradable plastic bag means that the plastic bag can be completely degraded into water and carbon dioxide. The main source of this fully degradable material is lactic acid, that is, PLA, which is processed from corn and cassava. It has good biodegradability. After use, it can be completely degraded by microorganisms in the nature under specific conditions, eventually generating carbon dioxide and water. It does not pollute the environment and is very beneficial to protect the environment. It is recognized as an environmentally friendly material.

如何区分：

How to distinguish:

1.观察外观：全降解塑料袋的原材料是PLA、PBAT、淀粉或矿粉材料，在外袋上会有专门的标志，比如常见的“PBAT+PLA+MD”，而对于可降解塑料袋，原料是PE等材料，常见的包括”PE-HD“等。

1. Observe the appearance: the raw materials of fully degradable plastic bags are PLA, PBAT, starch or mineral powder materials, and there will be special marks on the outer bags, such as the common "PBAT+PLA+MD", while for degradable plastic bags, the raw materials are PE and other materials, including the common "PE-HD".

2.用手触摸：由于原料不同两者的手感也有很大的差异。不同于塑料感的可降解塑料袋，全降解塑料袋摸起来手感丝滑柔软。

2. Touch with hands: Due to different raw materials, their hand feel is also very different. Unlike the degradable plastic bag with plastic feeling, the fully degradable plastic bag feels silky and soft.

3.闻其气味：可降解塑料袋通常是无味或者塑料气味，而全降解塑料袋尤其是淀粉基的袋子会有一点淡淡的粮食香味，材料本身也会带有一些玉米、木薯等香味。

3. Smell the smell: degradable plastic bags are usually tasteless or plastic, while fully degradable plastic bags, especially starch based bags, will have a slight smell of grain, and the materials themselves will also have some smell of corn, cassava, etc.

4.燃烧测试：传统塑料袋焚烧中会产生黑烟，同时会有刺鼻的气味，后还会留下燃烧过后的颗粒。而全降解塑料袋焚烧中无浓烟，不会有刺鼻的气味，燃烧后只剩下有机粉末，可被分解吸收。

4. Combustion test: The burning of traditional plastic bags will produce black smoke, with a pungent smell, and will leave burning particles. There is no smoke and pungent smell in the incineration of fully degradable plastic bags. After burning, only organic powder is left, which can be decomposed and absorbed.

5.区别：受到材料产能和成本的限制，目前质量较好的生物全塑料袋在大型的售价基本在0.5-2元每只，相对于仅0.2元左右的传统塑料袋要高上不少。

5. Price difference: Due to the limitation of material capacity and cost, the current price of biological full plastic bags with good quality in supermarkets is basically 0.5-2 yuan per bag, which is much higher than the traditional plastic bags with only 0.2 yuan.
