Nylon (NY) vacuum bags have good comprehensive properties, including mechanical properties, heat resistance, abrasion resistance, etc. The nylon vacuum bags made with it are not only waterproof, lightweight and tough, but also waterproof, lightweight and tough. Advantages, practical performance is extremely wide. Nylon film can be produced by tube film stretching method or flat biaxial stretching method. Nylon film is divided into two types: printing grade and composite grade. The printing grade can be used for printing and composite processes. The composite grade is only recommended for composite processes that do not require printing. Thickness generally has 12μm , 15μm , 25μm specifications. When used for intermediate layer compounding, and when used for boiling and cooking, double-sided corona film must be used.
PE is polyethylene, which has excellent low temperature resistance (the minimum operating temperature can reach -70 ~ -100 ℃ ), good chemical stability , can withstand the erosion of most acids and alkalis ( not resistant to acids with oxidizing properties ), insoluble at room temperature In general solvents , it has low water absorption , excellent electrical insulation performance, and poor heat aging resistance. Most of the plastic bags commonly used in life are made of PE film, which is non-toxic, so it can be used to hold food and the like. The plastic bag has indeed brought great convenience to people's lives since it was invented more than 100 years ago, but in the long run, the disadvantages it brings to society far exceed the convenience of the moment. In daily life, plastic bags are basically disposable, thrown away after use, and used up to two times on garbage bags. We all know that plastic structures are stable and are not easily degraded by natural microorganisms in the natural environment, so they become pollutants in the environment and exist for a long time, which ultimately causes great harm to the environment.
Nylon vacuum bag, also known as close-fitting moisture-proof bag and aluminum foil bag. Its material is generally NY / PE or PET / NY / AL / PE. Among them, PET -good printing effect, NY -low oxygen permeability, AL -barrier Strong, opaque, PE -the inner layer of the package. Glue: Water-soluble glue (more hygienic, environmentally friendly, without solvent residue) has good anti-static, oxygen barrier, shielding, moisture-proof, shading functions and excellent heat sealability.
