hvað er 8021 álpappír？

8021 álpappír hefur framúrskarandi rakaþol, skygging, og afar mikil hindrunargeta: lenging, gataþol, og sterkur þéttingarárangur.

The aluminum foil after compounding, prentun, og lím er mikið notað sem umbúðaefni. Aðallega notað fyrir matvælaumbúðir, þynnupakkning lyfja, mjúkir rafhlöðupakkar, o.s.frv.

Kostir 8021 álpappír

(1) The surface is clean and hygienic, og engar bakteríur eða örverur geta vaxið á yfirborði þess.
(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, en rifstyrkur hans er lítill, svo það er auðvelt að rífa það.
(6) As an opaque packaging material, it is a good packaging material for products exposed to sunlight, eins og smjörlíki.
(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.
