Multi-layer co-extrusion transfusion bag rubber plug puncture force monitoring solution

multi-layer co-extruded infusion bag because it does not use plasticizers and adhesives and other raw materials, and the material stability is not easy to occur with the liquid chemical adsorption, dissolution and other reactions, to avoid the fine particles mixed with the liquid on the human body cause some damages. However, whether or not the rubber plug used in the mouth of the infusion bag has a problem of desquamation due to the inability to pierce the bag is an issue of great concern for infusion bag manufacturers.
1, detection significance

At present, the infusion bag mainly adopts a composite film formed by a co-extrusion process as a packaging material, a three-layer coextruded composite film mainly composed of polypropylene (PP) and elastic material (SEBS), and an ester copolymer and ethylene methacrylate. The main material structure is a five-layer coextruded composite film consisting mainly of polymer, polyethylene, and modified ethylene-propylene polymer. This type of co-extruded infusion bag does not contain any plasticizers, does not use adhesives, and only generates water and carbon dioxide oxides after incineration; it is also made of PP, PE, which is not easily degraded or peeled off. The stability of the polymer, packaging material and the liquid contact without any reaction, no adsorption phenomenon, no glass bottle Alkali phenomenon, will not cause the packaging material particles dissolved into the liquid, to avoid harm to the human body, is currently the most secure One of the premium infusion packaging materials.
