8021 wide aluminum foil plays a key role as a barrier material. 8021 aluminum foil has excellent electrical conductivity and light-shielding properties, and has high moisture resistance, gas barrier properties and taste retention properties. It is widely used in soft-pack batteries, food packaging and pharmaceutical packaging.
Soft-pack batteries have multiple advantages such as good safety performance, light weight, large battery capacity, good cycle performance, small internal resistance, and flexible design. Four major factors, including increased penetration in the digital field, increased applications in the field of new energy vehicles, growing demand in high-rate fields such as drones, and the ready development of the energy storage field, will become the driving force for the increasing market share of soft-pack batteries. With the pull of the downstream market, the need for the 8021 and 8079 aluminum foil is very strong.
As one of the 8 series aluminum foils, 8021 aluminum foil is the most commonly used aluminum foil packaging product. It is inseparable from its good alloy properties. The surface of 8021 aluminum foil is extremely clean and hygienic. No bacteria or microorganisms can grow on the surface. It is a non-toxic packaging material that can be in direct contact with food without any danger to human health.
In addition, 8021 aluminum foil is an opaque packaging material. It is a good packaging material for products that need to be protected from sunlight. For example, margarine is commonly packaged in aluminum foil. In terms of food packaging, 8021 aluminum foil is mainly used in the kitchen for cooking, holding food, or for making some materials that can be easily cleaned.
8011 aluminum foil has a wider range of uses and can be used in many fields such as pharmaceutical packaging, food packaging, food container, tape foil, cable foil, bottle cap materials, etc., and the price is relatively favorable. 8021 aluminum foil is mostly used in the packaging of soft aluminum-plastic films for lithium batteries and blister medicines that require relatively high requirements, and the price is more expensive.
Pharmaceutical packaging is the continuation of pharmaceutical production and the last process applied to pharmaceuticals. As packaging materials and containers that directly contact pharmaceuticals, it is an organic component of pharmaceuticals. Therefore, medicinal aluminum foil has higher physical and mechanical properties, among which it requires the bursting strength shall not be less than 98Kpa.
With the development of society, the quality requirements of medical aluminum foil are getting higher and higher. Nowadays, some high-end drugs mostly use cold-formed medical foil. Cold-formed medical foil is generally based on 8021 aluminum foil. Haomei Aluminum has 8021 h14 aluminum foil in stock and can produce according to the customer requirements.
