普通包裝袋一方面給公眾帶來(lái)了很多方便，另一方面又污染了環(huán)境，一些包裝袋不能用來(lái)盛裝食品，對(duì)人體健康的危害不容低估。生物降解材料隨著人類(lèi)保護(hù)環(huán)境意識(shí)的提高，石油資源的不斷減少，生物降解聚合物取代傳統(tǒng)石油基聚合物已經(jīng)成為發(fā)展的趨勢(shì)。

On the one hand, ordinary packaging bags bring a lot of convenience to the public, on the other hand, they pollute the environment. Some packaging bags cannot be used to contain food, and the harm to human health cannot be underestimated. With the improvement of human awareness of environmental protection and the continuous reduction of petroleum resources, biodegradable polymers have become the trend of development to replace traditional petroleum-based polymers.

PBAT屬于熱塑性生物降解塑料，是己二酸丁二醇酯和對(duì)苯二甲酸丁二醇酯的共聚物，兼具PBA和PBT的特性，既有較好的延展性和斷裂伸長(zhǎng)率，也有較好的耐熱性和沖擊性能；此外，還具有優(yōu)良的生物降解性，是生物降解塑料研究中非?；钴S和市場(chǎng)應(yīng)用降解材料之一。

PBAT is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of PBA and PBT. It has good ductility and elongation at break, as well as good heat resistance and impact properties; In addition, it has excellent biodegradability, and is one of the most active biodegradable materials in the research of biodegradable plastics and market application.

生物降解顆粒原料在適當(dāng)和可表明期限的自然環(huán)境條件下，能夠被微生物完全分解變成低分子化合物的材料。生物降解陶瓷和生物降解性塑料兩類(lèi)。指出，食品，特別是熟食，用普通袋包裝容易變質(zhì)，吃這種變質(zhì)食品容易引起嘔吐、腹瀉等食物中毒癥狀。此外，塑料本身也會(huì)釋放出有害氣體，在密封袋的長(zhǎng)期積累中，隨著密封時(shí)間的增加，食品袋受到不同程度的污染，對(duì)兒童健康和發(fā)育的影響尤為明顯。

Biodegradable granular raw materials can be completely decomposed by microorganisms into materials with low molecular weight compounds under natural environmental conditions that are appropriate and can indicate the duration. Biodegradable ceramics and biodegradable plastics. Experts pointed out that food, especially cooked food, is easy to deteriorate when packaged in ordinary bags, and eating such deteriorated food is easy to cause vomiting, diarrhea and other food poisoning symptoms. In addition, plastic itself will also release harmful gases. In the long-term accumulation of sealed bags, with the increase of sealing time, food bags will be polluted to varying degrees, and the impact on children's health and development is particularly obvious.

常見(jiàn)的可生物降解塑料袋，在攤位上常用的顏色特別暗，可能會(huì)造成大的傷害。再處理回收的廢塑料制品，對(duì)人體危害很大，不能直接用于裝載進(jìn)口食品。此外，聚乙烯塑料制品不能用于儲(chǔ)存酒精食品、油類(lèi)食品。否則，袋子里的鉛會(huì)溶解在食物中。同時(shí)，這個(gè)普通的袋子不能放在超過(guò)50度的食物。更多相關(guān)產(chǎn)品事項(xiàng)就來(lái)我們網(wǎng)站http://www.qylxschool.cn咨詢(xún)！

The common biodegradable plastic bags are particularly dark in color at the booth, which may cause serious damage. Recycled waste plastic products are harmful to human health and cannot be directly used to load imported food. In addition, polyethylene plastic products cannot be used to store alcoholic food and oil food. Otherwise, the lead in the bag will dissolve in the food. At the same time, this ordinary bag cannot be placed in food with temperature higher than 50 ℃. Come to our website for more relevant product matters http://www.qylxschool.cn consulting service
