生物降解顆粒材質(zhì)袋子中，原材料有些來自于玉米、木薯、蔗糖等農(nóng)作物，因此與民爭糧成為一種擔憂。目前一些反饋是，材料充足，玉米淀粉使用的是儲備糧陳玉米。另外利用廢紙、竹子粉、玉米秸稈、木屑、稻草等材料的生物降解顆粒材質(zhì)袋子也在被研發(fā)出來，或正在研發(fā)。

Some of the raw materials in the biodegradable granular bags come from corn, cassava, sugar and other crops, so it is a concern to compete with the people for food. At present, some feedback is that the materials are sufficient, and the corn starch is used to store the aged corn. In addition, biodegradable granular bags made of waste paper, bamboo powder, corn straw, sawdust, rice straw and other materials are also being developed or under development.

現(xiàn)在，大部分塑料袋很少被重復使用，主要是因為塑料袋便宜，因此，想推廣塑料袋重復使用，需要塑料袋企業(yè)聯(lián)合建立押金回收體系，也不被丟棄，做不到押金回收，推廣重復使用、回收再造，都不能解決一部分塑料袋被隨意丟棄到海洋、山谷里的問題。

At present, most plastic bags are rarely reused, mainly because they are cheap. Therefore, if you want to promote the reuse of plastic bags, you need plastic bag enterprises to jointly establish a deposit recycling system, which will not be discarded. There is no way to recycle the deposit. The promotion of reuse and recycling can not solve the problem that some plastic bags are discarded into the ocean and the valley at will.

在分階段禁塑的階段，生物降解顆粒材質(zhì)袋子與不可降解袋同時在使用，就只有可堆肥的塑料袋了，中間這個交錯階段不能跳過，也不能因此而成為放棄的理由。即使可降解都進填埋場或者焚燒廠，與不可降解袋還是有差別的。

In the stage of staged plastic prohibition, biodegradable granular bags and non degradable bags are used at the same time, and only compostable plastic bags are available. The interlaced stage cannot be skipped, nor can it be a reason to give up. Even if degradable bags are put into landfills or incineration plants, they are different from non degradable bags.

伴隨著全球經(jīng)濟的發(fā)展壯大和科技創(chuàng)新的不斷進步，人民群眾對玉米的需求已向許多的新領域開拓。筆者得知，某省一個公司研制生產(chǎn)加工塑料吸管、餐具、餐墊等各類塑膠制品，主要是用玉米淀粉制成。

With the development of the global economy and the continuous progress of scientific and technological innovation, the people's demand for corn has expanded to many new areas. The author learned that a company in a certain province developed, produced and processed plastic straw, tableware, meal mats and other plastic products, mainly made of corn starch.

通過玉米淀粉和其他植物來源化合物制成的生物降解樹脂為特征的微生物塑料薄膜，實現(xiàn)95到240天的生物降解，降低環(huán)境污染。

Microbial plastic film characterized by biodegradable resin made of corn starch and other plant derived compounds can achieve biodegradation for 95 to 240 days and reduce environmental pollution.

生物降解袋主要是PBAT共聚酯和玉米提煉物PLA聚乳酸制造成的，無塑料成分添加，但是這種植物性成分的確實能全部降解，效果的自己試用下，生物降解不是市面上的可降解塑料袋哦，不要弄混了，因為是植物性成分，在承重方面要差些，畢竟這樣的新技術(shù)還不成熟，但普通的袋子用的話還是沒問題，在防水和拉伸性還可以。

Biodegradable bags are mainly made of PBAT copolyester and PLA polylactic acid, a corn extract. No plastic ingredients are added. However, this kind of vegetable ingredients can indeed be completely degraded. With its own trial effect, biodegradation is not a degradable plastic bag on the market. Don't mix it up. Because it is a vegetable ingredient, it is inferior in terms of weight bearing. After all, this new technology is not mature, but it is OK to use ordinary bags, The waterproof and tensile properties are OK.

現(xiàn)在技術(shù)還跟不上，比如小袋子的塑料降解袋，因為承重不需要那么重就可以替代，如果太重的話就需要更高的技術(shù)了，還有就是因為塑料袋有很多弊端如難處理，難分解等等，但是便宜，所以真的替代還需要一段時間！更多相關(guān)內(nèi)容就來我們網(wǎng)站http://m.qylxschool.cn進行咨詢吧！

The technology is not up to date. For example, the plastic degradable bags of small bags can be replaced because they do not need to be so heavy. If they are too heavy, they need higher technology. There are also many disadvantages of plastic bags, such as difficult to handle, difficult to decompose, etc., but they are cheap, so it will take a while to replace them!
