Problems solved by technology

[0003] At present, the infusion products in medical plastic packaging in the Chinese market are composed of soft bags made of non-PVC materials and hard plastic bottles made of polypropylene raw materials. These two medical plastic packagings are characterized by their light weight, good toughness, unbreakable, It is easy to transport and is not easy to produce harmful particles. At the same time, soft bags made of non-PVC films are gradually replacing polypropylene hard plastic bottles and becoming the mainstream packaging for infusion in the future. However, the above two plastic packaging forms have different weaknesses. For example, at present, most of the molding materials used in non-PVC soft bags manufactured in China are imported from the United States, which is expensive and high in production costs, making the cost of domestic non-PVC soft bag infusion bags high.
For example, the patent numbers applied by our company are: 200720080240.2, 200720080241.7 utility model patents, the materials used are non-PVC mold materials imported from the United States, but the price is expensive, the production cost is high, and the economic benefits are small

Abstract

The invention relates to a non-PVC material for medical infusion products and a preparation method thereof. The non-PVC material is characterized by comprising the following components by weight percent: 25-30% of SEBS, 45-49% of filling oil, 17-20% of PP, 6-7% of filler and 0.4-0.6% of antioxidant 1076. A disposable bag infusion set or a medical infusion product produced by the invention has the advantages of less precipitate, low drug adsorption, high transparency, light weight, more convenient treatment after use, environmental protection and the like. The non-PVC material does not react with paclitaxel and other fat emulsion anti-cancer drugs.

Description

technical field [0001] The invention relates to the technical field of plastic packaging materials for medical infusion products, in particular to a non-PVC material for medical infusion products and a preparation method thereof. Background technique [0002] In the past, soft polyvinyl chloride (PVC) was widely used as a packaging material for large infusion solutions. Due to the addition of various additives during the processing of PVC, the migration of small molecule additives and the chlorine element contained in PVC itself make it difficult to recover from processing to recycling. During the process, harmful components will be released. Clinically, the liquid reaction between PVC materials and drugs (such as paclitaxel, etc., fat emulsion anticancer drugs, etc.) often endangers the health of patients. According to the requirements of environmental protection, in recent years, international The world is working to limit or prohibit the use of PVC. Since the 1990s, devel...
