With the development of society and the improvement of people's living standards, food packaging has shown a diversified trend, and the types of packaging materials are increasing day by day. It is very necessary to pay attention to and improve the safety of food packaging materials. Food packaging materials refer to products used to package and hold food or food additives, and coatings that are in direct contact with food or food additives.
Metal packaging mostly uses aluminum foil, iron foil and tin-plated cans. When using aluminum foil, it is rarely used alone and is mostly used together with plastic film. 8011 aluminum foil is a commonly used packaging material.
8011 aluminum foil introduction:
8011 is a series of aluminum plates. It belongs to the 8××× series of alloy aluminum plates. It is added with Al-Fe-Si elements. It has higher advantages when it exceeds 1% of the total alloy elements. 8011 is commonly used to make aluminum foil. Its performance is better than that of pure aluminum foil, and it is widely used in aluminum foil.
8011 aluminum foil is one of the key products of GNEE Company. The thickness range of production is 0.018mm-0.2mm. The width can be controlled at 1650mm according to customer requirements. It has excellent moisture-proof performance, light-shielding and is extremely non-toxic, tasteless, safe and hygienic. Aluminum foil after lamination, printing, and gluing is widely used as packaging material.
The difference between 8011 aluminum foil and 8021 aluminum foil:
1. 8011 aluminum foil contains Mn and Mg elements, while 8021 aluminum foil does not contain these two elements, so the strength and corrosion resistance of 8011 aluminum foil are higher.
2. Aluminum foil 8011 has high strength, but its elongation and puncture resistance under the same conditions are lower than those of 8021 aluminum foil. Therefore, in pharmaceutical packaging, pharmaceutical aluminum foil coatings are mostly 8021 aluminum foil, but the requirements for sealing and elongation are Higher blister aluminum and tropical aluminum mostly use 8021 aluminum foil and 8079 aluminum foil;
3. Aluminum foil 8011 has a wider range of uses and can be used for pharmaceutical packaging, food packaging, lunch box materials, tape foil, cable foil, milk cap materials, bottle cap materials, etc. 8021 aluminum foil is relatively expensive and is mostly used for relatively high requirements. Lithium batteries are soft-packed in aluminum-plastic film and blister pharmaceutical packaging.
