如今越來越多的客戶和消費(fèi)者開始注重塑料袋的環(huán)保性，開始了解綠色降解塑料袋，但其實(shí)降解可分為“可降解”和“全降解”兩種。如何區(qū)分二者呢？可降解顆粒生產(chǎn)廠家為您講解。

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產(chǎn)過程中加入一定量的添加劑使其穩(wěn)定性下降，比較容易在自然環(huán)境中降解。這種塑料制品雖然可以降解，但是并不能完全降解。并且這種石油基制品是通過化學(xué)反應(yīng)而不是微生物有機(jī)分解，所以并不能完全分解成有機(jī)物，相反會(huì)分解成微小的碎片進(jìn)入環(huán)境，這些微塑料被動(dòng)物攝入進(jìn)入食物鏈，可通過生物圈回到人類社會(huì)引起重大問題。

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與二氧化碳。這種全降解材料的主要來源是由玉米、木薯等經(jīng)過加工變成乳酸，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條件下完全降解，終生成二氧化碳和水，不污染環(huán)境，對(duì)保護(hù)環(huán)境非常有利，是公認(rèn)的環(huán)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.

如何區(qū)分：

How to distinguish:

1.觀察外觀：全降解塑料袋的原材料是PLA、PBAT、淀粉或礦粉材料，在外袋上會(huì)有專門的標(biāo)志，比如常見的“PBAT+PLA+MD”，而對(duì)于可降解塑料袋，原料是PE等材料，常見的包括”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.用手觸摸：由于原料不同兩者的手感也有很大的差異。不同于塑料感的可降解塑料袋，全降解塑料袋摸起來手感絲滑柔軟。

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.聞其氣味：可降解塑料袋通常是無味或者塑料氣味，而全降解塑料袋尤其是淀粉基的袋子會(huì)有一點(diǎn)淡淡的糧食香味，材料本身也會(huì)帶有一些玉米、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.燃燒測試：傳統(tǒng)塑料袋焚燒中會(huì)產(chǎn)生黑煙，同時(shí)會(huì)有刺鼻的氣味，后還會(huì)留下燃燒過后的顆粒。而全降解塑料袋焚燒中無濃煙，不會(huì)有刺鼻的氣味，燃燒后只剩下有機(jī)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.區(qū)別：受到材料產(chǎn)能和成本的限制，目前質(zhì)量較好的生物全塑料袋在大型的售價(jià)基本在0.5-2元每只，相對(duì)于僅0.2元左右的傳統(tǒng)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.
