Abstract

The invention relates to a membrane material for a transfusion soft bag and application of the membrane material. The membrane material is obtained by at least co-extruding an outer layer material, a middle layer material and an inner layer material, wherein the outer layer material comprises PP (Polypropylene), PE (Polyethylene) and SEBS (Styrene-Ethylene-Butadiene-Styrene segmented copolymer), wherein the PP accounts for 60wt%-99wt%, the PE accounts for 0.5wt%-30wt% and the SEBS accounts for 0.2wt%-20wt%; the middle layer material comprises PP, PE and SEBS, wherein the PP accounts for 20wt%-90wt%, the PE accounts for 0.5wt%-20wt% and the SEBS accounts for 0.2wt%-65wt%; and the inner layer material comprises PP, SEBS, TPO (Thermoplastic Polyolefin) and polyolefin wax, wherein the PP accounts for 37wt%-99wt%, the SEBS accounts for 0.1wt%-30wt%, the TPO accounts for 0.2wt%-9wt% and the polyolefin wax accounts for 0.1wt%-7wt%. The membrane material for the transfusion soft bag does not contain PVC (Polyvinyl Chloride) or DEHP (Diethylhexyl Phthalate) and a heat transfer film can be used for printing words or coating colors and printing; the membrane material for the transfusion soft bag has good low-temperature resistance falling performance and separation performance; and a false welding connection part can be formed in the inner layer to prepare the multi-chamber transfusion soft bag.

Description

technical field [0001] The invention relates to the field of transfusion packaging materials, in particular to a film material for transfusion soft bags and its application. Background technique [0002] The current infusion packaging mainly includes glass bottles, polyvinyl chloride (PVC) soft bags, polypropylene (PP) or polyethylene (PE) hard plastic bottles, polyethylene acetate (EVA) soft bags and non-PVC soft bags. [0003] The glass bottle is fragile and precipitates. During the infusion process, it is necessary to continuously introduce air into the solution through the ventilation line to generate pressure, and the dust and microorganisms (such as bacteria, fungi, etc.) in the air can enter the glass bottle through this, causing contamination of the infusion. Mixing is required, and glass bottles are gradually being phased out. [0004] Although the PVC soft bag has solved the air pollution problem of the original bottled semi-open infusion clinically, the organochl...
