Borong 8021 aloi aluminium foil

apa yang 8021 aloi aluminium foil？

8021 kerajang aluminium aloi mempunyai rintangan kelembapan yang sangat baik, teduhan, dan keupayaan penghalang yang sangat tinggi: pemanjangan, rintangan tusukan, dan prestasi pengedap yang kuat.

The aluminum foil after compounding, percetakan, dan gluing digunakan secara meluas sebagai bahan pembungkusan. Terutamanya digunakan untuk pembungkusan makanan, pembungkusan ubat lepuh, pek bateri lembut, dan lain-lain.

Kelebihan Daripada 8021 kertas aluminium

(1) The surface is clean and hygienic, dan tiada bakteria atau mikroorganisma boleh tumbuh di permukaannya.
(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, tetapi kekuatan koyakannya kecil, jadi mudah koyak.
(6) As an opaque packaging material, it is a good packaging material for products exposed to sunlight, seperti marjerin.
(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.
