Abstract

The invention discloses an environment-friendly high-barrier multi-layer coextrusion medical transfusion film. The medical transfusion film adopts a seven-layer film compound structure and comprises an A layer, a B layer, a C layer, a D layer, an E layer, an F layer and a G layer which are successively arranged from outside to inside, wherein the A layer is a mixed resin outer layer prepared from PCCE and PEN by reacting, blending and esterification; the B layer is a first bonding layer composed of an ethylene methyl acrylate copolymer; the C layer is a secondary-core layer composed of metallocene linear polyethylene; the D layer is a core layer composed of a high-temperature resistant ethylene-vinyl alcohol copolymer; the E layer is a secondary-core layer composed of the metallocene linear polyethylene; the F layer is a second bonding layer composed of metallocene linear polyethylene grafted maleic anhydride; and the G layer is an inner layer composed of an ethylene-propylene copolymer. The medical transfusion film has the characteristics of environmental friendliness, good transparency, excellent thermal weldability, high-temperature resistance, chemical resistance, high barrier property, etc., and can be extensively applied to the field of high-barrier medical transfusion packaging.

Description

technical field

[0001] The invention belongs to the field of medical polymer materials, and in particular relates to an environment-friendly high-barrier multilayer co-extrusion medical transfusion film. Background technique

[0002] The annual demand for infusion solution in my country has reached more than 10 billion (bottle) bags, and it is increasing at an annual rate of 15-20%, ranking first in the world. Due to many defects, glass bottles and plastic bottle infusion packaging materials will be gradually replaced by new products, resulting in a downward trend in usage rate. However, a large number of PVC infusion soft bags currently on the market contain the plasticizer DEHP. This plasticizer will be dissolved from the infusion soft bags and mixed into the liquid medicine. Many patients have pyrogenic reactions due to this, and damage the reproductive function of boys. , and even cause harm to the fetus in the pregnant woman's womb. The State Drug Administration once ...
