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.

再者塑料袋的批发很便宜，廉价的塑料袋更是许多小商贩的选择，不管健康不健康，更别说环保了。禁止塑料袋并不是方法，既然屡禁不止，为什么不找个更合适的方法替代呢？自封袋就是很不错的替代品。

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，但是包装食物散货的，衣服的，都可以使用自封袋来替代，这样可以循环使用，一个质量好的自封袋相信很多人都不是随便丢弃的，重复使用率很高。

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.

而且让商家的产品显得档次也很高，也为顾客着想，提升了体验度。这样的例子还有很多，觉得问题在于商家，需要商家们自觉改变，来带动顾客改变这种观念，才能逐渐的减少劣质塑料袋，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.
