The medical care kit is made of three layers of co-extruded film. No adhesive is used. The cleaning of the film and the molding of the soft bag are all completed in the 100-level clean workshop. There is no pyrogen and no particles. For its structure, we should Learn about.
The medical care kit is a three-layer plastic material with different melting points such as polypropylene (PP), polyethylene (PE), polyamide (PA) and various elastic materials (SEBS), which are coextruded under 100 clean conditions. .
Inner layer: It is a completely non-toxic inert polymer. It is chemically stable and does not fall off or degrade foreign matter. Polypropylene (PP) and polyethylene (PE) are usually used.
Middle layer: It is a dense material with excellent water and gas barrier properties. Such as polypropylene (PP), polyamide (PA).
Outer layer: Mainly to improve the mechanical strength of medical care kits. The materials used in soft bags on the market today are usually polypropylene (PP), polyamide (PA) and the like.
In addition, from the production process of medical care kits, the melting point of the three layers of materials is different, gradually increasing from the inside to the outside, which facilitates heat sealing from the inside to the outside, making it more tight and firm, which is also superior to PVC materials (high frequency welding from the outward direction One aspect of doing it inside.
In recent years, medical care kits use the latest international packaging materials, which are highly practical and suitable for people's use under aseptic conditions.
