Abstract

The invention discloses a high-density and high-barrier polyethylene plastic thin film and a making method thereof. The high-density and high-barrier polyethylene plastic thin film comprises a thin film body and waterproof layers; an upper thin film layer is arranged above the thin film body, a first thickening layer is connected under the upper thin film layer, a reinforcing layer is fixed on thefirst thickening layer, a second thickening layer is connected under the reinforcing layer, a lower thin film layer is arranged under the second thickening layer, the waterproof layers are arranged on the surfaces of the upper thin film layer and the lower thin film layer, the first thickening layer and the second thickening layer are symmetrically distributed about the reinforcing layer, the first thickening layer comprises a first layer body, an absorbing layer and a second layer body, and the absorbing layer is arranged between the first layer body and the second layer. The high-density and high-barrier polyethylene plastic thin film and the making method thereof disclosed by the invention have the benefit that the high-density and high-barrier polyethylene plastic thin film is improved aiming at the defects of the conventional polyethylene plastic thin film technology so as to be high in density and strong in barrier effect and have the function of absorbing odor, thereby being more convenient to use.

Description

technical field [0001] The invention relates to the technical field of polyethylene plastic film, in particular to a high-density and high-barrier polyethylene plastic film and a production method thereof. Background technique [0002] With the improvement of people's living standards, the awareness of product packaging quality assurance and hygiene assurance continues to increase. It is difficult for existing single packaging materials to meet multiple special needs, so composite materials have emerged as the times require, and polyethylene plastic film is the One of the most important film bags in packaging. [0003] For the existing polyethylene plastic film, there are still a lot of problems, such as the existing polyethylene plastic film has low density and poor barrier effect, which affects the use effect of polyethylene plastic film, while the existing polyethylene plastic film Plastic film does not have adsorption function, so we propose a high-density high-barrier ...
