Aluminum foil sheet is a packaging material that has not yet been replaced. It has many advantages such as non-toxicity, heat conduction, shading, moisture barrier and fragrance preservation. The appearance of aluminum foil for food packaging has greatly improved the level of food processing.
Aluminum foil is made of electrolytic aluminum with a purity of more than 99.5% and is made by rolling. Its reflectivity can reach 95%. It is stable no matter it is at high temperature or low temperature. It is an excellent middle-layer substrate film for high-grade retort packaging.
Aluminum foil for food packaging is widely used for high-grade packaging for chocolate,sealing film for instant noodle bowls, sealing labels for beer and champagne, compound packaging for milk and dairy products and fruit juices, etc. Due to its low strength, it is rarely used alone. The aluminum foil thickness for food can be 0.007~0.009mm, which is also more economical.
At present, thinner aluminum foil has five to six hundred pinholes per square meter, and if its necessary strength is neglected, it can only be moisture-proof. If its thickness is more than 20μm, it can meet the requirements of no holes and moisture resistance.
In actual use, in addition to packaged foods and medicines, the thickness selection should be based on different contents. There is a reference for you:
Alloy | Thickness | Major Applications | Features |
1085 | 12 μm-200 μm | Electrolytic capacitors, etc. | 99.85% (or greater) pure aluminum |
3003 | 12 μm-200 μm | Ornamental panels, etc. | Highly strong and durable |
3004 | 30 μm-200 μm | Ornamental panels, etc. | Highly strong and durable |
8021 | 6 μm-200 μm | Food, pharmaceuticals, etc. | High-performance aluminum foil |
