Description of 8021 aluminum foil
Our 8021-O state aluminum foil base material, etc., are the source of aluminum foil raw materials for various lithium battery soft-package aluminum-plastic films and cold-formed medicinal aluminum foil packaging.
Advantages of 8021 aluminum foil:
1. Safe and non-toxic, water brushing is Grade A, and the cup convexity is high;
2. Strong mechanical performance;
3. Excellent moisture resistance, shading and high barrier ability;
4. The surface is clean, the color is uniform, no spots, no oil stains, smooth and no voids;
5. Bacteria, mold and other tests, heavy metals do not exceed 0.25% per million, strictly implement industry standards to ensure safety and health.
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 is higher than that of 8021 aluminum foil;
2. Aluminum foil 8011 has high strength, but the corresponding elongation and puncture resistance performance are lower than 8021 aluminum foil in the same state. Therefore, in drug packaging, the aluminum foil coating on the back of the drug capsule plate is mostly 8021 aluminum foil, and it is sealed 8021 aluminum foil and 8079 aluminum foil are mostly used for blister aluminum and tropical aluminum with higher requirements for performance and elongation;
3. Aluminum foil 8011 is more widely used. It can be used in many fields such as medicine packaging, food packaging, lunch box material, tape foil, cable foil, milk cap material, bottle cap material, etc., while 8021 aluminum foil is relatively expensive and is mostly used for requirements. Relatively high lithium battery soft pack aluminum plastic film and blister medicine packaging.
Export Wooden Case
Suitable for export and high-end customers, strong protection, moisture-proof and anti-collision:
Structure: The aluminum foil roll is first wrapped with moisture-proof materials (such as plastic film, kraft paper), and then placed in a wooden box with lining. Advantages: Suitable for long-distance transportation, moisture-proof, dust-proof and anti-collision.Commonly used for: food foil, medicine foil, household foil, electronic foil and other high-requirement products
Vertical Suspension
Suitable for thinner and heavier aluminum foil rolls: The aluminum foil roll is hung vertically in the wooden box, and the roll core is fixed to the box body by a steel rod or sling. Advantages: Reduce the risk of pressure or deformation of the edge of the aluminum foil during transportation.Commonly used for: high-precision electronic foil, lithium battery foil and other products with high edge requirements
Packaging for narrow strip aluminum foil
Plastic film wrapping + carton or wooden box
Method: Each roll or several rolls is wrapped with moisture-proof plastic film (PE);
The outer layer is protected with kraft paper or foam cushioning material;
Multiple rolls are concentrated in a carton or wooden box;
Suitable for: general industrial foil, such as cable foil, capacitor foil
Pyramid-shaped Packaging
For smaller reels aluminum foil but longer width foil ,we will use Pyramid-shaped Packaging to save the space and shipping cost .
