Problems solved by technology

[0008](4) The particle dissolution is extremely low, which is lower than any glass.
These technologies have high energy and low selectivity, and the free radicals generated are easy to react with oxygen in the air to form polar groups of alcohols, acids, and esters, thereby forming polar hydrophilic ends and non-polar hydrophobic ends surface active molecule
[0015] Non-PVC multi-layer co-extruded infusion drug packaging films irradiated by electron beams have similar problems to PVC packaging materials: 1. A large amount of surfactants produced potential hazard to human health
2. After electron beam irradiation, an insoluble and infusible network structure is formed, which is not easy to decompose and cannot be recycled. It can only be solved by burning, which will cause great harm to the environment

Abstract

The invention relates to a five-layer coextrusion transfusion medicine packing film. The five layers have the materials and the structure that the layer A is the outer layer of a product and is made of polyester or copolyester with the thickness of 10-30 Mum, the layer B is the secondary outer layer of the product and is made of acid modified polyolefin copolymer or the mixture thereof with the thickness of 3-15 Mum, the layer C is the middle layer of the product and is made of the mixture of polyethylene, polypropylene and SEBS with the thickness of 30-80 Mu m, the layer D is the secondary inner layer of the product and is made of the mixture of polyethylene, polypropylene and SEBS with the thickness of 40-110 Mu m, and the layer E is the inner layer of the product and is made of the mixture of co-polypropylene and SEBS with the thickness of 10-40 Mu m. The transfusion medicine packing film is transparent and highly flexible, can be sterilized at high temperature, the outer layer can be printed permanently with conventional pigments and has the functions of impact resistance and abrasion prevention. The inner layer can simply be bonded via heat seal without electron beam irradiation or any additives, and has lower water vapor permeability and oxygen and nitrogen penetration amount. The invention also discloses a manufacturing method of the film.

Description

technical field [0001] The invention relates to a packaging film for transfusion medicine, in particular to a five-layer co-extruded film for packaging transfusion medicine, and a manufacturing method thereof. technical background [0002] With the continuous advancement of science and technology, the materials and containers used for pharmaceutical packaging are also undergoing tremendous changes. The packaging materials used for large-capacity injections have gradually developed from glass decades ago to plastics such as polypropylene and polyethylene. And their various combinations, the packaging form has also developed from a single type to the coexistence of bottle type and bag type, and new packaging forms are also being developed. Plastic flexible packaging for infusion has the advantages of light weight, not easy to break, easy to form and convenient for various designs, etc., which is more in line with the requirements of modern industrial production, and meets the ...
