Vacuum compression bag material difference

The vacuum compression bags currently on the market are mainly made of two materials, one is PA+PE. PA is an abbreviation for polyamide, commonly known as nylon, and PE is an abbreviation for polyethylene, which is ordinary plastic. The vacuum compression bag of PA+PE is made of a new plastic compounded with nylon and plastic. The vacuum compression bag of this material is relatively soft, and does not change the trait when it is cold, and is relatively durable. The other is PET+PE. PET is an abbreviation for polyethylene terephthalate, commonly known as polyester polyester. PET+PE is a combination of polyester polyester and ordinary plastic. The vacuum compression bag made of PET+PE is not soft enough, especially hard and crack at low temperature. It is better for friends in the north to use vacuum compression bags of this material.

So how do you identify these two different materials? To be honest, a friend who has never used a vacuum compression bag is like a counterfeit banknote. A high-simulation counterfeit banknote is difficult to distinguish between true and false, but the original shape is contrasted with the real banknote. Therefore, to identify two different materials, it is best to compare the two together. The method is: one touch, the softer feel is PA material, the harder one is PET material. Second, listen to it by hand, the sound is more blunt is PA material, the sound is sharp and harsh is PET material. The third is to put the two materials in the freezer of the refrigerator for a while, and the harder one is PET.

Nowadays, many branded compression bags on the Internet are sold very cheaply, and they are also said to be PA+PE. This vast consumer can be wary of shackles. Many merchants will make some PA+PE recycled materials into compressed bags, and they will be very thick, 9 wires, 12 wires, etc. (1 wire is equal to 0.01mm) to reduce costs and thus carry out low-cost promotions. Distinguish the recycled material mainly depends on the transparency of the bag and the purity of the light transmission of the bag.

Purchase

First, look at the material: There are two main composite materials on the market today, one is PET+PE; the other is PA+PE. So what is the difference between these two materials? In terms of cost, PA is higher than PET, technical indicators are different, and quality is better. In terms of appearance, the material of the PA material is softer than the PET product.
Second, look at the thickness, this is the reason for the large price difference, in general, there are three main types on the market, 0.06MM, 0.08MM, 0.10MM, for the home, the most suitable is still 0.08MM.
Third, look at the appearance: must look at the appearance of the product is not obvious defects, mainly hard wrinkles, damage, dirt, etc., if these are not good, indicating poor production conditions. Then the quality will not be too good!
Fourth, the most important point is that the basic purpose of our purchase of this product is to maintain a vacuum. Just don't have a leak, if there is a leak, then this product is useless!
