識別全生物降解垃圾袋知識

降解材料因為殊降性，很多為淀粉和纖維素類的可生化材料，通常自然條件下，堆肥降解時間約180天自然條件下也不會超過1年的時間。也就是說，可降解塑料袋保質(zhì)期僅有1年以內(nèi)，即使不用，1年后也期本上無法使用了，也會出現(xiàn)自然降解現(xiàn)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.

降解包裝袋的標志，可降解塑料袋上有統(tǒng)一的環(huán)境標志，為清山、綠水、太陽及十個環(huán)組成的綠色標志，如果是食品用塑料袋，還需印有食品許可QS標識，并標注“食品用”。如下圖所示：

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:

降解包裝袋的儲存，全生物降解垃圾袋保質(zhì)期短，所以在儲存上也需要特別的留意，需要避免陽光直曬，包裝要好。

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.

為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”問題，在地底不分解，對農(nóng)作物、水源、畜牧以及人類本身都有危害。而全生物降解垃圾袋埋在土壤里以后，因為周圍的環(huán)境可以滿足分解要求，會完全分解為二氧化碳和水，屬于有機循環(huán)，對人體和環(huán)境無害。

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.
