Abstract

The invention provides a material for a transfusion hose and an application of the material. The material is obtained by coextruding at least one outer layer material, a middle layer material and an inner layer material, wherein the outer layer material is prepared from the following components in percentage by weight: 50-99 percent of PP and 1-50 percent of SEBS, totally 100 percent; the middle layer material is prepared from the following components in percentage by weight: 30-70 percent of PP and 30-70 percent of SEBS, totally 100 percent; the inner layer material is prepared from the following components in percentage by weight: 10-45 percent of PP and 55-90 percent of SEBS, totally 100 percent. The material is high in weldability, soft, high in transparency, high in elasticity and suitable for coextrusion.

Description

technical field [0001] The invention relates to the field of materials used for infusion, in particular to a material for infusion hose and its application. Background technique [0002] The main packaging methods currently used in large infusion packaging are glass bottles, plastic bottles, and co-extruded infusion films, and the interfaces used are also very different. The glass bottle interface is molded together with the bottle body, both are single-mouth systems, and the lid is sealed with a rubber stopper and an aluminum cap, which is the most traditional packaging method. The mouth tube of the plastic bottle is also plasticized together with the bottle body, and the cap is sealed with an injection-molded composite cap. The raw material is single and the required technology is simple. At present, domestic infusion manufacturers widely use it. Co-extruded transfusion membranes mainly use PP single-port injection tube system in China. The material is relatively simple a...
