Guangzhou food vacuum bag size can be customized
Also known as aluminum plastic composite bag
Vacuum bags, also known as close fitting moisture-proof bags, aluminum foil bags, and aluminum plastic composite bags, are generally made of PET/AL/CPE or PET/NY/AL/CPE. PET - good printing effect, NY - low oxygen permeability, AL - strong barrier and opaque, and CPE - inner layer of packaging.
Glue: water soluble glue (more hygienic, environmental protection, no solvent residue) This product has good anti-static, oxygen isolation, shielding, moisture-proof, shading functions and excellent heat sealing. Shanghai Food Vacuum Bag Customization Factory
After the food is vacuum packed, the pressure inside the packaging bag is greater than the pressure outside the packaging bag, which can effectively prevent the food from being crushed and deformed under pressure without affecting the appearance of the packaging bag and the printing decoration. The vacuum inflatable package is filled with nitrogen, carbon dioxide, oxygen or a mixture of two and three gases after vacuum. Guangzhou Coarse Grain Vacuum Bag Customization Factory
The nitrogen is an inert gas, which plays a filling role to keep the positive pressure inside the bag, so as to prevent the air outside the bag from entering the bag and protect the food. Its carbon dioxide can be dissolved in various fats or water, leading to weak acid carbonic acid, and has the activity of inhibiting mold, putrefactive bacteria and other microorganisms. Its oxygen can inhibit the growth and reproduction of anaerobic bacteria, maintain the freshness and color of fruits and vegetables, and high concentration of oxygen can keep fresh meat bright red.

High barrier: co extrusion film with high barrier performance of different plastic materials is used to achieve high barrier effect on oxygen, water, carbon dioxide, odor, etc.
Stable performance: oil resistance, moisture resistance, low temperature freezing resistance, quality assurance, fresh-keeping, odor protection, can be used for vacuum packaging, aseptic packaging, inflatable packaging. Shanghai cereals vacuum bag size can be customized
Low cost: compared with glass packaging, aluminum foil packaging and other plastic packaging, co extrusion film has greater advantages in cost to achieve the same barrier effect.
