According to the vacuum compressed bags product model, it is divided into four types: hanger bag, garment bag, and quilt bag and box compression bag. There are two types of polyethylene (PE), composite film (PET/PE, composite film PA/PE) depending on the material.

Polyethylene (PE) is very sensitive to environmental stresses (chemical and mechanical effects) and has poor heat aging resistance.The composite (PET+PE) bag has better adhesion and is also a material used in the bag. However, the disadvantage of such a vacuum compression bag is that it is relatively brittle. Composite (PA + PE), the bag of this material is better in flexibility, high in adhesion, not easy to leak, so the cost is relatively high.

Material determines the quality of the product. For the above two different types of material combinations, we can see that PET + PE bags, the adhesion is better, but also the more materials used in the bag, also known as high-strength composite film. However, everyone should note that the disadvantage of this vacuum compression bag is that it is very brittle. In addition, it is the common MOPE and PVC compression bag in the supermarket. The bag of this material has poor adhesion.

Although it feels softer than other compression bags, it feels better, but the material determines that it is easy to leak. I suggest everyone Be cautious when purchasing. Combining the characteristics of various types of products, it is obvious that PA+PE is the best choice for everyone to vacuum-compress bags, because the bag of this material has better flexibility and higher adhesion, and it is not easy to leak. Perhaps the higher cost of PA+PE itself may be relatively higher, but the quality is not normal.
