Problems solved by technology

[0004] The three-layer co-extrusion film for infusion has a simple structure and low manufacturing cost, but the heat resistance of the film is not high, the heat sealing range is narrow, and the requirements for bag making equipment are high. At the same time, it is limited by the performance of polypropylene materials. It is not soft enough, especially in the alpine region, this kind of infusion packaging method is prone to leakage, which has great safety hazards; the five-layer co-extrusion film for infusion has good weather resistance, low bag leakage rate, and processing adaptability Good, but the materials used in the outer and sub-outer layers are expensive, which greatly increases the packaging cost of the liquid medicine

Embodiment Construction

[0024] Such as figure 1 Shown is a schematic structural view of a five-layer medical liquid medicine packaging film in the present invention.

[0025] refer to figure 1 , a five-layer medical liquid pharmaceutical packaging film proposed by the present invention can be used to manufacture flexible packaging bags for packaging and using medicinal liquids. The medicinal liquids that can be packaged and used include: saline solution, glucose solution, cleaning solution, dialysate and Various other liquid medicines.

[0026] The film has a five-layer composite structure of an outer layer A, a sub-outer layer B, a core layer C, a sub-inner layer D and an inner layer E, wherein:

[0027] Outer layer A: its composition is homopolypropylene or high-density polyethylene, adding 0wt%-50wt% antioxidant, ethylene bisstearamide, poly-4-methylpentene, SEBS, calcium stearate , polyethylene and other processing aids or one or more materials in modified materials.

[0028] Sub-outer layer ...

Abstract

The invention provides a five-layer medical liquid reagent packaging film and a preparation method thereof. The film has excellent optical property, mechanical property and heat stability, is safe, environment-friendly and non-toxic, does not has side effects, has the advantages of both a five-layer film and a three-layer film and also the advantages of lower preparation cost of the three-layer film as well as has the characteristics of good heat sealability, good weatherability, good safety and the like of the five-layer film.

Description

technical field [0001] The invention relates to the technical field of medical films, in particular to a five-layer medical liquid drug packaging film and a manufacturing method thereof. Background technique [0002] The packaging methods for intravenous injection mainly include glass bottles, plastic bottles, PVC soft bags, three-layer co-extruded infusion films and five-layer co-extruded infusion films. 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 c...
