Abstract
The utility model provides a novel three-layer co-extrusion composite packaging film for transfusion, which adopts a three-layer film composite structure, and comprises a polyamide layer, an ethylene methyl acrylate copolymer layer and a modified polypropylene layer which are sequentially distributed from the inner part to the outer part, wherein the modified polypropylene layer has the effect of improving the heat sealing strength, and the polyamide layer has the effect of enhancing the strength. The novel three-layer co-extrusion composite packaging film has the benefits that the film improves the barrier property, has high strength, is not easy to break, and reduces the production cost.
Description
Technical field
The utility model relates to a kind of composite package film based on medical, particularly relates to a kind of novel three-layer co-extruded transfusion composite package film.
Background technology
In numerous curable products, transfusion goods are one of classifications of wherein consumption maximum, in Europe, the United States and economically developed country, the soft bag rate of infusion products generally reaches more than 95%, and still less than 6% of the utilization rate of China, disposable use multi-layer co-extrusion infusion can be used for making the soft bag of multi-layer co-extrusion infusion with composite package film, it is environmentally friendly packing material, represent the highest level of current transfusion package material, it is genuine new high-tech product, the main product of world today's transfusion package material, for developed country extensively adopts.
But the three-layer co-extruded transfusion composite package film using at present both at home and abroad, exists that barrier is bad, intensity is not high, easily breaks and problem that production cost is high.
Utility model content
The purpose of this utility model is to solve that existing three-layer composite packaging film barrier is bad, intensity is not high, easily break and problem that production cost is high.
To achieve these goals, the utility model provides a kind of novel three-layer co-extruded transfusion composite package film, adopts trilamellar membrane composite construction, comprises aramid layer, ethylene methyl acrylate copolymer layer and modified polypropene layer that ecto-entad is arranged in order.
Wherein said aramid layer thickness is 80-100um, and ethylene methyl acrylate copolymer layer thickness is 15-20um, and modified polypropene thickness is 80-100um.
Wherein, modified polypropene layer plays the effect that improves heat seal strength, and aramid layer plays the effect of gaining in strength.
The beneficial effects of the utility model are: improve barrier, the intensity of three-layer composite packaging film high, be difficult for breaking and reducing production cost.
Accompanying drawing explanation
Fig. 1 is layer structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe preferred embodiment of the present utility model in detail.
As shown in Figure 1, the present embodiment provides a kind of novel three-layer co-extruded transfusion composite package film to embodiment, adopts trilamellar membrane composite construction, comprises aramid layer, ethylene methyl acrylate copolymer layer and modified polypropene layer that ecto-entad is arranged in order.
Wherein said aramid layer thickness is 100um, and ethylene methyl acrylate copolymer layer thickness is 20um, and modified polypropene thickness is 100um.
Wherein, modified polypropene layer plays the effect that improves heat seal strength, and aramid layer plays the effect of gaining in strength.
The beneficial effect of the present embodiment is: improve barrier, the intensity of three-layer composite packaging film high, be difficult for breaking and reducing production cost.
