How to distinguish the advantages and disadvantages of plastic packaging bags? I believe that many people are still ignorant of this matter. They feel that the vest bag is just an insignificant thing, whichever you choose is good, and the product itself is not expensive, only a few cents a piece. This idea is hugely wrong. Because for some big sellers, they will buy large quantities of goods every time. If they pick a product that is not very good, it is not a problem of two or three bad products at this moment, but a large number of large quantities, and the loss is also large. Next, biodegradable plastic bag manufacturers explain the difference between good and bad packaging plastic bags.

At present, some high-quality plastic vest bags on the market usually include three aspects. Simply put, they are the alkali resistance level, the stretch level, and the ability to withstand cracking. Among them, the most critical is of course the alkali resistance level. The reason is that on the basis of alkalinity, if the stretch becomes larger, the strength of the packaging plastic bag will become weaker during use, and the anti-crack function will be useless. When it comes to the alkali resistance of plastic vest bags, it is mainly determined by the raw materials processed so far and the neutralizing agent added.

The plastic vest bags of counterfeit and shoddy products usually have the following conditions: first, it may be made again from those secondary packaging plastic bags that have already been used; , the product itself has been added some harmful chemical raw materials, such packaging plastic bags have a very low safety factor; however, consumers cannot distinguish the above with the naked eye, so they still need to pay more attention. However, it is very fortunate that the supervision of fake and inferior plastic products has been tightened in the market, and high-quality plastic packaging bags are still the mainstream of the market.
