Embodiment Construction

[0020] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments:

[0021] Such as figure 1 as shown, figure 1 It is a schematic cross-sectional structure diagram of a three-layer medical liquid drug packaging film proposed by the present invention.

[0022] refer to figure 1 , a three-layer medical liquid pharmaceutical packaging film proposed by the present invention is used to manufacture flexible packaging bags for packaging and using medical liquid. The medical liquid pharmaceutical includes: saline solution, glucose solution, cleaning solution, dialysate and various other medicines liquid. The above-mentioned three-layer medical liquid drug packaging film has an ABC three-layer composite structure, wherein:

[0023] Layer A: It constitutes the outer surface of the film. Layer A is a weather-resistant layer with temperature stability and high barrier properties. Its comp...

Abstract

The invention discloses a three-layer medical liquid medicament packaging film which has a composite structure with three layers A, B and C, wherein the layer A forms the outer surface of the film and comprises the ingredients of homo-polypropylene or a mixture of homogeneous propylene and SEBS (Thermoplastic Elastomer); the layer B comprises the ingredients of polypropylene random copolymer, SEBS, POE (Polyolefin Elastomer), mPE (Metallocene Polyethylene) or the mixture of two or more than two of the materials; the layer C forms the inner surface of the film and comprises the ingredients of polypropylene random copolymer and / or a mixture of ethylene-propylene-butene terpolymer and SEBS, wherein the SEBS is 8-24wt% in weight percent. The medical liquid medicament packaging film has comprehensive properties of excellent weather resistance, good heat sealability, high transparency, high tenacity, high barrier property and the like, and has wide adaptability to a full-automatic filling sealing production line in the pharmacy process.

Description

technical field [0001] The invention relates to the technical field of medical films, in particular to a three-layer medical liquid drug packaging film and a manufacturing method thereof. Background technique [0002] At present, the packaging methods for intravenous injection mainly include glass bottles, plastic bottles and PVC soft bags. Glass bottle or plastic bottle infusion packaging, in clinical operation, needs to be suspended and inserted into the air inlet needle, in order to complete the infusion with the help of external air pressure, which belongs to an open infusion, and the liquid medicine is easily polluted by the air. Therefore, in mines and other special It cannot be used in medical emergencies under environmental conditions. PVC soft bag infusion packaging solves this problem. The bag body of PVC soft bag has flexibility and good transparency. During clinical infusion, it can form a fully closed infusion system with the human body, relying on the shrinkag...
