How to distinguish the quality of plastic bags? How to remove the label on the plastic bag?

How to distinguish the quality of plastic bags? It is believed that many people still have no idea about this. They think that the vest bag is nothing but a trifle. It is good to choose it any way, and the product itself is not expensive. A few cents will not make them feel trapped even if they buy it badly. This idea is a big mistake.
Because for some big sellers, they will purchase in large quantities every time. If they pick out bad products, they will not be bad for one or two, but will lose a lot in batches. Therefore, Xiao Bian believes that it is necessary to introduce some skills to distinguish between good and bad vest bags here.
Some good plastic vest bags on the market generally include three aspects: alkali resistance, tensile strength and crack resistance. Of course, alkali resistance is the core.
The reason is that on the basis of alkalinity, if the tensile strength is large, the strength of the plastic bag will be reduced during use, so the crack resistance function is useless.
When it comes to the alkali resistance of plastic vest bags, it is mainly determined by the raw materials processed and auxiliary agents added.
Fake and shoddy plastic vest bags generally have the following conditions:
First of all, it may be re manufactured from those used secondary packaging plastic bags;
Secondly, it is also possible that some toxic chemicals are added to the product itself during the processing of plastic packaging bags, so the safety of such plastic packaging bags is very low; However, it is difficult for consumers to distinguish the above with the naked eye, so they still need to pay more attention.
Fortunately, the market has stepped up the monitoring of low-quality plastic products, and good plastic bags are still the mainstream of the market.

2. Soak the daily necessities with labels in water, and wipe them off after the labels are soaked. This method is also applicable to metal and plastic tools, but it is time-consuming.
3. Directly use a lighter to burn on the other side of the metal product label for a while, and the glue on the label will quickly melt. This method is fast and effective, but it can only be applied to metal products.
4. Apply the essential balm on the label, and then open the label after a few minutes. The label will fall off together with the adhesive. Even if the stubborn sticker traces are smeared with essential balm and then picked with fingernails, the traces can usually be cleaned up quickly.
