Permanent-antistatic high-barrier functional film and manufacturing method thereof

Abstract

The invention discloses a permanent-antistatic high-barrier functional film and a manufacturing method thereof. The technical solution is that the permanent-antistatic high-barrier functional film comprises an EVOH high-barrier layer; PA anti-piercing layers are respectively arranged on the upper and lower surfaces of the EVOH high-barrier layer; anti-delamination layers are arranged on the surfaces, opposite to the EVOH high-barrier layer, of the PA anti-piercing layers; and permanent-antistatic layers are arranged on the surfaces, opposite to the PA anti-piercing layers, of the anti-delamination layers. The permanent-antistatic high-barrier functional film provided by the invention has permanent-antistatic property which is 8-9 power of 10, so that dust particles in the air are permanently not collected on the surface layer and the inner layer of the film; and the permanent-antistatic high-barrier functional film has ultrahigh anti-piercing and high barrier properties, so that the micro-organisms in the air and the separation of rays such as infrared rays and ultraviolet rays for the packages during direct sunlight can be blocked. According to the permanent-antistatic high-barrier functional film and the manufacturing method thereof, the reliability and safety of packaging products such as food, medicines and medical devices are ensured.

Description

Technical field [0001] The invention relates to the technical field of functional film manufacturing, in particular to a permanent antistatic high barrier functional film and a manufacturing method thereof. Background technique [0002] For anti-static functional films, there are mainly two anti-static effect film manufacturing processes in the current production process. One is to add oily antistatic agents to achieve the antistatic effect of the film. The disadvantage is that there will be oil on the surface, which can only be short. Turnover use within time; the second is to coat 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 shortcomings of the prior art, how to add permanent antistatic materials in the production, while ensuring that the film is not greasy, a...
