All countries are controlling and banning the use of plastic bags. The reason is that the pollution of the environment has caused harm to animals and land, but it has not stopped. Take China as an example, plastic bags are still popular. Although plastic bags are charged in supermarkets, customers still can afford to pay a few cents. It doesn't matter.

再者塑料袋的批發很便宜，廉價的塑料袋更是許多小商販的選擇，不管健康不健康，更別說環保了。禁止塑料袋并不是方法，既然屢禁不止，為什么不找個更合適的方法替代呢？自封袋就是很不錯的替代品。

Moreover, the wholesale of plastic bags is very cheap, and cheap plastic bags are the choice of many small traders, no matter whether they are healthy or not, let alone environmental protection. Banning plastic bags is not a way. Since it has been banned repeatedly, why not find a more suitable way to replace it? Self sealing bag is a good substitute.

一些大的塑料袋可以使用，但是包裝食物散貨的，衣服的，都可以使用自封袋來替代，這樣可以循環使用，一個質量好的自封袋相信很多人都不是隨便丟棄的，重復使用率很高。

Some large plastic bags can be used, but self sealing bags can be used to replace food, bulk goods and clothes. In this way, they can be recycled. I believe that a good quality self sealing bag is not discarded casually by many people, and the reuse rate is very high.

而且讓商家的產品顯得檔次也很高，也為顧客著想，提升了體驗度。這樣的例子還有很多，覺得問題在于商家，需要商家們自覺改變，來帶動顧客改變這種觀念，才能逐漸的減少劣質塑料袋，更多的使用自封袋。

Moreover, it makes the products of the merchants appear to be of high grade, and it also takes care of the customers and improves the experience. There are still many such examples. I think the problem lies in the merchants. They need to consciously change to drive customers to change this concept. Only in this way can they gradually reduce inferior plastic bags and use more self sealing bags.
