The use of aluminum foil in food packaging bags is due to the good barrier properties of aluminum foil. The oxygen transmission rate of aluminum foil is extremely low, which can effectively block the gases in the air that are easy to deteriorate food, such as oxygen and gas. Moreover, the aluminum foil is opaque and has good shading properties to prevent certain foods from being discolored or deteriorated due to exposure to light. The aluminum foil itself has extremely poor corrosion resistance and is easily corroded by acidic or alkaline substances. 8011-O aluminum foil is mostly used. The 8011 aluminum foil produced by MC Aluminum has clean surface, uniform color, no spots, flat and no holes.
The 8011 moisture-proof aluminum foil bag has metallic luster, good light-proof performance, and high reflection ability to heat and light. The metal luster and reflection ability can improve the brightness of printing colors; it has good insulation, strong protection, airtight gas and water vapor, and prevents The content absorbs moisture and vaporizes, and is not easy to be attacked by bacteria and insects; it has good shape stability and is not affected by humidity changes. It is easy to process, and can be printed, colored, embossed, surface coated, glued and painted on the aluminum foil bag; the composite aluminum foil bag also has the advantages of insulation.
Moisture-proof aluminum foil bag production process:
Aluminum ingot smelting—casting and rolling—cold rolling—intermediate annealing—cold rolling—aluminum foil wool—rough rolling—intermediate rolling—finish rolling (double combination)—slitting—annealing of finished aluminum foil— Compounding - bag making - finished aluminum foil bag - packaging.
MC Aluminum provides aluminum foil substrates for raw materials of moisture-proof aluminum foil bags, and does not produce finished products.
The main advantages of food packaging bags made of aluminum foil are as follows:
1. High temperature resistance (up to 121 degrees), low temperature resistance (minus 50 degrees), some food packaging bags used for high temperature cooking can use this material;
2. Good oil resistance and outstanding fragrance retention performance;
3. Excellent barrier performance, strong air barrier performance, anti-oxidation, waterproof and moisture-proof;
4. Good heat sealing performance and high softness;
5. Food packaging bags made of aluminum foil are non-toxic, tasteless, healthy and safe in line with national health standards.
MC Aluminum is a large-scale aluminum foil manufacturer, which can undertake orders of 1-200 tons, with stable product quality and affordable prices. The 8011 aluminum foil produced can not only be used as food packaging materials, but also can be used in the production of aluminum bottle caps, food, pharmaceutical packaging and radiators, etc. It has excellent performance and is not easy to oxidize to produce chemical reactions. raw materials.
