▎ 摘　　要

NOVELTY - High density polyethylene medical device packaging high temperature turnover antibacterial film comprises a three-layer structure, the outer layer is DuPont Tyvek, middle layer made by blending high density polyethylene and linear low-density polyethylene, the inner layer made by mixing GO-Ag in polyethylene terephthalate glycol. The polyethylene terephthalate glycol is polyethylene terephthalate-1,4-cyclohexanedimethanol, and the thickness ratio of the outer layer, middle layer and inner layer is 3:1:3.. USE - Used as high density polyethylene medical device packaging high temperature turnover antibacterial film. ADVANTAGE - The film adapts high temperature conditions of sterilization, and has sterilization ability, fewer side chains, and more densely compressed chains, higher crystallinity, molecular weight and density, better toughness, tear resistance, high mechanical strength and strong tear resistance.
