Problems solved by technology

[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

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the drawings.

[0019] Such as figure 1 As shown, a permanent antistatic high-barrier functional film includes an EVOH high-barrier layer. The upper and lower surfaces of the EVOH high-barrier layer are respectively provided with a PA anti-piercing layer. The PA anti-piercing layer has a high barrier to EVOH. One side of the layer is provided with an anti-release layer, and the side of the anti-release layer opposite to the PA puncture-resistant layer is provided with a permanent antistatic layer.

[0020] The permanent antistatic high-barrier functional film of the present invention, in which the EVOH high-barrier layer can make the film achieve the most obvious barrier effect, and the PA anti-piercing layer can improve the piercing resistance of the film and enhance the barrier effect, preventing release The layer is used to firmly connect the PA anti-piercing layer and the permanent antistatic laye...

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 present invention relates to the technical field of functional film manufacturing, and in particular to a permanent antistatic high barrier functional film and a manufacturing method thereof. Background technique [0002] For antistatic functional films, there are two main manufacturing processes for antistatic films in the current production process. One is to add oily antistatic agents to achieve the antistatic effect of the film. The disadvantage is that oil will appear on the surface and can only be used for a short period of time. The second is to apply the antistatic agent on the surface of the film to achieve the antistatic effect. However, 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 existing technology, how to add permanent antistatic materials in production while ensuring that the film...
