We found that some ziplock bags have a red line on the seal, and some are still green. What is this for?
In fact, the multi-colored lines on the seal of my ziplock bags are to distinguish the quality of the ziplock bags. Most of the ziplock bags are the same size, but the thickness and quality are different, so it is not very obvious to distinguish them with the naked eye. We have said before that the self-sealing bag is divided into 20 wires, 12 wires, etc., which is the thickness index of the self-sealing bag, so the weight of the self-sealing bag with different thicknesses is also different. The red and green lines are to distinguish the weight of the ziplock bag, so that it is not easy to confuse.
How to calculate the price of ziplock bags?
The price of a ziplock bag is determined by its quality and size. The size of the ziplock bag is different, the small one can only hold one opening, and the large one can hold clothes, etc. Naturally, the price is different. There are also different thicknesses of ziplock bags and different prices. Another situation is that the production materials of the ziplock bags will also be different and affect the price. The price of the ziplock bag should be judged according to the real object.
