Venta al por mayor 8021 papel de aluminio de aleación

qué es 8021 papel de aluminio de aleación？

8021 El papel de aluminio de aleación tiene una excelente resistencia a la humedad., sombreado, y capacidad de barrera extremadamente alta: alargamiento, resistencia a la perforación, y un fuerte rendimiento de sellado.

The aluminum foil after compounding, impresión, y el pegado se utiliza ampliamente como material de embalaje. Utilizado principalmente para envasado de alimentos., embalaje de medicamentos en ampolla, paquetes de baterías blandas, etc..

Las ventajas de 8021 papel de aluminio

(1) The surface is clean and hygienic, y ninguna bacteria o microorganismo puede crecer en su superficie.
(2) It is a non-toxic packaging material, which can be in direct contact with food without any danger of harming human health.
(3) It is an odorless and odorless packaging material, which will not make the packaged food have any peculiar smell.
(4) No matter whether in high temperature or low temperature, there will be no oil penetration phenomenon.
(5) High hardness and high tensile strength, pero su fuerza de desgarro es pequeña, entonces es fácil de romper.
(6) As an opaque packaging material, it is a good packaging material for products exposed to sunlight, como margarina.
(7) It has good plasticity, so it can be used for packaging products of various shapes. Various shapes of containers can also be arbitrarily formed.

Battery Soft Package Aluminum Foil

The commonly used specification of battery soft-pack aluminum foil is 0.035-0.055mm.

8021’s plain aluminum foil material has good performance and extensibility, and the commonly used thickness is 0.04mm. The main advantage is that it is used in deep-drawing packaging materials.

aluminum foil battery Have The Following Advantages:

1. High energy density. The general battery capacity can be about 2200mAh, so the energy density is about 500Wh/L, and the energy density of the polymer battery is now
   Stage mass production can be close to 600Wh/L.
2. Good safety. Polymer batteries do not have this problem. Even in the same situation, due to the low strength of the packaging film, as long as the e-air pressure is slightly higher, it will rupture and will not explode.
   Explosion, the worst case is burning.
