How much do you know about PET vacuum packaging bags?

How much do you know about PET vacuum packaging bags? PET vacuum packaging bags have good transparency and high glossiness; Has excellent gas barrier sealing performance and fragrance retention performance; Moderate moisture resistance, with a decrease in moisture permeability at low temperatures. After being compounded with different materials, it can be used for low-temperature and high-temperature cooking. For example, PET/PE is suitable for low-temperature use, while PET/CPP is suitable for high-temperature cooking. Next, Jinde Packaging will give you a detailed introduction:

1. Vacuum packaging bags made of PET material have excellent mechanical properties, with good strength and toughness compared to thermoplastic materials. Their tensile strength and impact strength are much higher than those of general films; And it has good rigidity and stable size, suitable for secondary processing such as printing and bag making.

2. PET vacuum packaging bags also have excellent heat and cold resistance, as well as good chemical and oil resistance. The combination of PET can achieve good chemical stability against acid, alkali, and common organic solvents. PET vacuum bags can maintain their excellent physical and mechanical properties over a wide temperature range.

3. The composite structure of PET vacuum packaging bags generally includes:

PET/PE，

In order to increase the texture and performance of vacuum packaging bag materials, three-layer and four layer composite materials are also used,

PET/PA/PE

PET/AL/CPP

PET/PA0/AL/CPP
