识别全生物降解垃圾袋知识

降解材料因为殊降性，很多为淀粉和纤维素类的可生化材料，通常自然条件下，堆肥降解时间约180天自然条件下也不会超过1年的时间。也就是说，可降解塑料袋保质期仅有1年以内，即使不用，1年后也期本上无法使用了，也会出现自然降解现象。

Due to their unique degradability, many biodegradable materials are starch and cellulose based. Under natural conditions, the degradation time of compost is usually about 180 days, and under natural conditions, it does not exceed one year. That is to say, the shelf life of biodegradable plastic bags is only within one year. Even if they are not used, they will no longer be usable after one year, and natural degradation will occur.

降解包装袋的标志，可降解塑料袋上有统一的环境标志，为清山、绿水、太阳及十个环组成的绿色标志，如果是食品用塑料袋，还需印有食品许可QS标识，并标注“食品用”。如下图所示：

The logo of the degradable packaging bag has a unified Chinese environmental logo on the degradable plastic bag, consisting of a green logo consisting of clear mountains, green water, sun, and ten rings. If it is a plastic bag used for food, it must also be printed with a food safety permit QS logo and labeled as "for food use". As shown in the following figure:

降解包装袋的储存，全生物降解垃圾袋保质期短，所以在储存上也需要特别的留意，需要避免阳光直晒，包装要好。

The storage of biodegradable packaging bags has a short shelf life, so special attention should also be paid to storage, avoiding direct sunlight, and ensuring good packaging.

为什么要使用全生物降解垃圾袋，可降解塑料袋、塑料餐具是生物可降解的新型材料。普通塑料袋、塑料餐具涉及到“白色污染”问题，在地底不分解，对农作物、水源、畜牧以及人类本身都有危害。而全生物降解垃圾袋埋在土壤里以后，因为周围的环境可以满足分解要求，会完全分解为二氧化碳和水，属于有机循环，对人体和环境无害。

Why use fully biodegradable garbage bags? Biodegradable plastic bags and plastic tableware are new types of biodegradable materials. Ordinary plastic bags and tableware involve the problem of "white pollution", which does not decompose underground and poses a threat to crops, water sources, animal husbandry, and humans themselves. After fully biodegradable garbage bags are buried in the soil, because the surrounding environment can meet the decomposition requirements, they will completely decompose into carbon dioxide and water, belonging to the organic cycle and harmless to human health and the environment.
