What about the packaging and recycling of medical plastic bottles?

It is understood that medicinal plastic bottles have become the symbol of innovative development in pharmaceutical packaging industry and have been successfully listed. There is a steady rise in the demand for the packaging of medicinal plastic bottles around the world.
Pharmaceutical plastic bottles are mainly made of medical compound packaging materials, and the plastic bottles are mostly high-density polyethylene plastic products. The global demand for the packaging of medicinal plastic bottles is increasing every year, and the packing growth rate of medical plastic bottles is the top. In the medical plastic bottle, the performance of the high end is the medicinal PET plastic bottle.
Pharmaceutical PET plastic bottles have excellent chemical resistance. Made of medicinal PET plastic food packaging conform to the requirements of the food hygiene, because PET resin is not only a harmless resin, but also a kind of pure resin without any additives, is considered to be a qualified and safe medicine and food packaging materials.
The medicinal PET bottle has good gas barrier property. In the commonly used plastic, the PET bottle has the best barrier of water vapor and oxygen, which can fully meet the special storage requirements of drug packaging. PET has excellent chemical resistance, can be used for all items except part of alkali and organic solvent of packaging, PET recycling utilization rate is higher than other plastic resin, as the combustion of waste processing, due to its heat of combustion of low caloric value and inflammable, and does not produce harmful gases.
Made of PET food packaging is in line with food hygiene requirements, because the PET resin is not only a harmless resin, but also a kind of pure resin without any additives, it passed the plastic bottles, including the u.s., Europe and Japan fairly strict inspection of food hygiene law, is considered to be a qualified and safe medicine and food packaging materials.
At present, the production of PET in the world to double-digit rate of growth, a medicinal plastic bottles made of polyester as the main raw material both from the appearance, luster, and the physical and chemical performance, from the quality assurance is one of the most ideal varieties.
Plastic bottles are made from polyethylene or polypropylene and are added with a variety of organic solvents. Most of the beverage bottles are plastic products, polyethylene and polypropylene, which are non-toxic and tasteless, and can be used to fill drinks and so on. But once polyethylene is exposed to high temperature or acid corrosion, it will dissolve slowly and release organic solvents, which can cause harm to human body. Plastic bottles melt spinning, dissolving unsaturated resins or reproducing grains, but making transparent products can easily be found with poor transparency and opaque particles.
Polyethylene property
Polyethylene odourless, non-toxic, feel like wax, has good low temperature resistance (the lowest temperature can reach 70 ~ 100 ℃), chemical stability is good, most of acid and alkali erosion (acid) with characteristics of oxidation resistance, temperature does not dissolve in solvents, small water imbibition, excellent electrical insulation properties; But polyethylene is very sensitive to environmental stress (chemical and mechanical), and it has a poor aging resistance.
The properties of polyethylene vary from breed to breed, depending on the molecular structure and density.
It is mainly used for making film, container, pipe, single wire, wire and cable, daily necessities, etc., and can be used as high frequency insulation material for TV, radar and so on.
