Embodiment 1

[0011] A plastic film includes a base layer and a glass flake layer, the base layer is PET, PBT or acrylic polymer, and the glass flake accounts for 20% of the total weight of the film. The thickness of the glass flake layer is 50-60 nm. The average particle size of the glass flakes in the glass flake layer is 10-15 nm. The glass flakes are silicate glass.

Embodiment 2

[0013] A plastic film includes a base layer and a glass flake layer, the base layer is PET, PBT or acrylic polymer, and the glass flake accounts for 30% of the total weight of the film. The thickness of the glass flake layer is 100 nm. The average particle size of the glass flakes in the glass flake layer is 20 nm. The glass flakes are phosphate glass.

Abstract

The invention discloses a plastic film, which comprises a base layer and a glass flake layer, the base layer is PET, PBT or acrylic polymer, and the glass flake accounts for 5-30% of the total weight of the film. The glass flake layer has a thickness of 50-100 nm. The average particle size of the glass flakes in the glass flake layer is 5-20 nm. The glass flakes are silicate glass or phosphate glass. A benefit of the present invention is that the incorporation of glass flakes into suitable polymeric or other films can reduce or inhibit the permeation of said films by a variety of materials including gases, vapors, chemicals or odors. In addition, the glass flakes can enhance properties including mechanical strength, stiffness or flexural modulus, heat distortion temperature, and tear strength. In addition, the nucleation properties and refractory properties of the film can be improved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a plastic film. Background technique [0002] Thermoplastic materials are widely used in packaging due to their low cost and ease of forming them into various shapes and packaging capabilities. However, such materials often suffer from the drawback of providing only relatively poor barriers to gas and vapor diffusion and to chemical and / or odor contamination. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a plastic film with filler added. [0004] The technical solution of the present invention is realized in the following way: a plastic film includes a base layer and a glass flake layer, the base layer is PET, PBT or acrylic polymer, and the glass flake accounts for 5-30% of the total weight of the film. [0005] The glass flake layer has a thickness of 50-100 nm. [0006] The average particle size of the glass flak...
