There are two types of fresh-keeping bags we use in our daily lives, one is PE fresh-keeping bags, and the other is PVC fresh-keeping bags. The former is mainly used for food packaging, and the latter is different from the material itself. It is related to the reasons, so it can only be used for the packaging of some perishable foods such as vegetables and fruits. It is rarely used for the packaging of greasy foods, and it cannot be used for heating in microwave ovens.

As for the plastic bags used in the bulk and fruit and vegetable sections of supermarkets, they are not fresh-keeping bags but ordinary plastic bags. Although they are similar in length to fresh-keeping bags, they are all rolled up. In fact, they have another name called tear bags or supermarket roll bags. In terms of material, tear-off bags can be divided into roll bags for cooked food and roll bags for non-food items. The former is required to meet the prescribed food safety standards, while the latter is generally made of PE material and can be added inside. Some calcium carbonate, so in this case the cost is very low and the price will be very cheap, but this type of supermarket roll bags cannot be used for food packaging. I hope everyone can distinguish these two aspects when using them in life.

I don’t agree with supermarket bag charges, because supermarkets have always taken the price difference from retail goods, so it is inappropriate to charge shopping bags. You transfer the profit from the product. When others buy the product, you should look for packaging. Our bag charging business is much worse. This is what customers say, and they charge packaging fees when buying things.

We know that the starting point for charging for shopping bags is to limit plastics and reduce pollution. But when consumers have not developed the habit of carrying a basket and a bag for shopping, is charging useful? He will still use it when it's time to use it. The only good thing is that the supermarket has added another income-increasing project.

It is not a question of whether to support charging for shopping bags. The provision of plastic shopping bags should be completely eliminated and replaced with environmentally friendly and reusable paper bags. The harm of plastic products to the ecology is obvious, and some African countries are banning the use of plastic shopping bags, and as a country that uses a lot of plastic bags, shouldn’t we stop using them? Reducing white pollution starts with each of us. I believe our ecological environment will be better! ?
