普通包装袋一方面给公众带来了很多方便,另一方面又污染了环境,一些包装袋不能用来盛装食品,对人体健康的危害不容低估。生物降解材料随着人类保护环境意识的提高,石油资源的不断减少,生物降解聚合物取代传统石油基聚合物已经成为发展的趋势。

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 can not be used to hold food, and the harm to human health can not be underestimated. With the improvement of people's awareness of environmental protection and the continuous decrease of petroleum resources, biodegradable polymers have become the development trend to replace traditional petroleum based polymers.
pbat属于热塑性生物降解塑料,是己二酸丁二醇酯和对苯二甲酸丁二醇酯的共聚物,兼具PBA和PBT的特性,既有较好的延展性和断裂伸长率,也有较好的耐热性和冲击性能;此外,还具有优良的生物降解性,是生物降解塑料研究中非常活跃和市场应用降解材料之一。
PBAT is a kind of thermoplastic biodegradable plastics. It is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of PBA and PBT. It has good ductility, elongation at break, heat resistance and impact resistance; In addition, it has excellent biodegradability, and is one of the most active biodegradable materials in the research and market application of biodegradable plastics.
生物降解颗粒原料在适当和可表明期限的自然环境条件下,能够被微生物完全分解变成低分子化合物的材料。生物降解陶瓷和生物降解性塑料两类。专家指出,食品,特别是熟食,用普通袋包装容易变质,吃这种变质食品容易引起呕吐、腹泻等食物中毒症状。此外,塑料本身也会释放出有害气体,在密封袋的长期积累中,随着密封时间的增加,食品袋受到不同程度的污染,对儿童健康和发育的影响尤为明显。
Biodegradable granular materials can be completely decomposed into low molecular weight compounds by microorganisms under appropriate and demonstrable natural environmental conditions. There are two kinds of biodegradable ceramics and biodegradable plastics. Experts pointed out that food, especially cooked food, is easy to deteriorate when packed in ordinary bags. Eating this kind of deteriorated food is easy to cause food poisoning symptoms such as vomiting and diarrhea. In addition, the plastic itself will 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, especially for children's health and development.
常见的可生物降解塑料袋,在摊位上常用的颜色特别暗,可能会造成极大的伤害。再处理回收的废塑料制品,对人体危害很大,不能直接用于装载进口食品。此外,聚乙烯塑料制品不能用于储存酒精食品、油类食品。否则,袋子里的铅会溶解在食物中。同时,这个普通的袋子不能放在超过50度的食物。
Common biodegradable plastic bags, the color commonly used in stalls is particularly dark, which may cause great harm. The recycled waste plastic products do great harm to human body and cannot be directly used for loading imported food. In addition, polyethylene plastic products can not 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 can't be placed in food over 50 degrees.
环保袋一般是指其生产材料能够自然分解,分解时间不会太长,而且可以反复使用的袋子,可以称为环保袋。这就是概念。
Environmental protection bag generally refers to the bag whose production materials can decompose naturally, the decomposition time is not too long, and can be used repeatedly, which can be called environmental protection bag. That's the concept.
