Which medical plastic bottle is low? Welcome to inquire + 86-15916785363. Our factory specializes in the production of pharmaceutical plastic bottles, pharmaceutical plastic bottles, etc. Based on the use of medicinal plastic bottles, consider the use of convenient use, the appearance of the medicinal plastic bottle is getting more and more diverse, and various bottles shape constantly appear. It enrichs the market, but plastic surrounding equipment manufacturers have challenged. The first challenge comes from the blowing machine industry, from the large to dozens of small 1 ml of medicinal plastic bottles, the blowing machine must meet the needs of processing, combined with a diversified bottle shape, to ensure the quality of medicinal plastic bottles, and how Increasing production efficiency is a prioritized blower manufacturer.
The second challenge comes from blowing molds, various special shapes of pharmaceutical plastic bottles, blowing mold manufacturing is a big challenge, requires a process of continuous improvement of blowing machines, of course, this is also an opportunity. Reimbura businesses, from traditional surface labeling machine types increasing. Medicinal plastic bottles typically thermosetting plastic materials include phenolic resins, epoxy resins, amino, unsaturated polyesters, furan, materials such as silica ethers, and new EPS diethyl acrylate plastics, etc., their advantages are highly resistant, heat Not easily deformed.
At present, the growth rate of polyester produced in the world, polyester fiber of pharmaceutical plastic bottles is the main raw material, no matter from the appearance, gloss, it is still the ideal packaging product in terms of chemistry and physical functions and quality assurance. Pharmaceutical plastic bottle packaging processing technology, polyester raw material for raw material blown bottle polyester (PET) saturated linear thermoplastic polyester, main application function index: inherent viscosity (IV) should be controlled at 70 ~ 85 ML / g, the blow molded bottle has high mechanical strength and transparency. PET pharmaceutical plastic bottles are used in a large number of (greater than 2 liters), and the viscosity of polyester raw materials is 70 ~ 75 mL / g.
The high viscosity index yield of the characteristics of the material is preferably selected by the drug volume small injection molded bottle. Because the choice of raw material varieties is accurate, the process of the production process parameter selection is related to the quality of the body. Therefore, it is especially important to produce a pharmaceutical plastic bottle, the characteristics of the raw materials, crystallization temperature, cooling speed, and direction of the process.
This is because the polyester material is the crystallization of the polymer, and the crystallization rate is small.
