There are two kinds of fresh-keeping bags we use in our daily life, one is PE fresh-keeping bag, and the other is PVC fresh-keeping bag. The former is mainly used for food packaging, and the latter can only be used for packaging some perishable foods such as vegetables and fruits because of the material itself, and it is rarely used for packaging oily foods, let alone for heating in microwave ovens.

For the plastic bags used in bulk areas and fruit and vegetable areas in supermarkets, they are not fresh-keeping bags but ordinary plastic bags, although they are almost the same as fresh-keeping bags, and they are all rolled up. In fact, they have another name called hand-torn bags or supermarket roll-up bags. Hand-torn bags can be divided into two types according to the material: rolled bags for cooked food and rolled bags for non-food. The former is required to meet the prescribed food safety standards, while the latter is generally made of PE, and some calcium carbonate can be added to it, so the cost is very low and the price will be very cheap. However, this kind of supermarket rolled bags can not be used for food packaging. I hope everyone can distinguish these two aspects when using them in life.

I don't agree with the supermarket bag charge, because the supermarket has taken the difference in retail goods, so it is not appropriate to charge shopping bags again. You have diverted profits from the goods, and you should look for packaging when others buy products. We charge for bags here, and his business is much worse. That's what customers say, and they charge for packaging when they buy things.

We know that the starting point of charging for shopping bags is to limit plastics and reduce pollution. But when consumers haven't got into the habit of bringing a basket and a bag to shop, is it useful to charge? He can still use it if he should. The only advantage is that the supermarket has added another item to increase income.

It's not a question of whether we support the charging of shopping bags. We should completely cancel the provision of plastic shopping bags and replace them with environmentally-friendly reusable paper bags. The harm of plastic products to the ecology is obvious to all. Some African countries are banning the use of plastic shopping bags, but as a big country using plastic bags, shouldn't we stop using them? Less white pollution starts from each of us, and I believe our ecological environment will be better! ?
