Abstract

The invention discloses a coextruded permanent antistatic high-barrier film and a production technology thereof. The coextruded permanent antistatic high-barrier film comprises an EVOH high-barrier layer, the upper surface and the lower surface of the EVOH high-barrier layer are respectively provided with an anti-piercing PA layer, a bonding layer is arranged at one side, opposite to the EVOH high-barrier layer, of the anti-piercing PA layer, a PE layer is arranged at one side, opposite to the anti-piercing PA layer, of the bonding layer, and a permanent antistatic layer is arranged at one side, opposite to the bonding layer, of the PE layer. The coextruded permanent antistatic high-barrier film of the invention have a higher structural strength and a lower production cost than permanent high-barrier films in the prior art.

Description

technical field [0001] The invention relates to the technical field of functional film manufacturing, in particular to a co-extruded permanent antistatic high-barrier film and a production process thereof. Background technique [0002] For antistatic functional films, there are mainly two manufacturing processes for antistatic film in the current production process. One is to add oily antistatic agent to achieve the antistatic effect of the film. The disadvantage is that oil will appear on the surface, which can only be shortened. The second is to apply the antistatic agent on the surface of the film to achieve the antistatic effect, but this process can only guarantee the effective antistatic effect within 6 months, and there will be no antistatic characteristics after more than 6 months. Therefore, in view of the deficiencies in the prior art, how to add permanent antistatic materials in production and ensure that the film is not oily, and the manufacturing process with pe...
