Medicinal composite packaging materials, mainly medicinal PVC plastic bottles. It has the advantages of light weight and low price, easy to form large-scale production, and can be made into bottles of various specifications and various colors. The printing performance of plastic bottles is very good, so it has become the most important packaging container for medicines. Medicines packaged in plastic bottles are mainly solid tablets, pills, capsules and powders for oral preparations, as well as liquid solutions and emulsions.

Plastic bottles used for medicine packaging are mainly made of polyvinyl chloride (PVC), polyethylene, polypropylene, polystyrene and other materials. Medicinal polyvinyl chloride sheet (PVC) is the bottom material of aluminum-plastic blister packaging. In order to improve the barrier properties of the PVC hard film, you can choose PVC/PVDC composite hard film, or use cold aluminum “lunch box” packaging and add desiccant and aluminum-plastic composite bag packaging. The forms of medicinal composite films and bags can be described as various. The material structures are: paper/plastic, plastic/aluminized plastic, paper/aluminum foil/plastic and plastic/aluminum foil/plastic, etc., and their barrier properties increase in order.

Among them, the material of plastic itself is divided into PE, CPP, BOPE, BOPET, BOPA, etc. Due to its strong comprehensive advantages and incomparable superiority of its materials, although it will cause certain harm to the environment, it is still widely welcomed. Its consumption has increased rapidly and has partially replaced other materials such as glass infusion bottles. Pharmaceutical manufacturers can choose appropriate pharmaceutical packaging according to the barrier properties of the pharmaceutical packaging materials and the packaging form of the pharmaceuticals, as well as other factors such as transparency, aesthetics, ease of taking medicines, and economy.

The sheet used for blister packaging is called rigid film or film. Commonly used are: PET (polyethylene terephthalate) rigid film, PVC (polyvinyl chloride) rigid film, and PS (polystyrene) rigid film. PS hard film has low density, poor toughness, and is easy to burn. It will produce styrene gas (a harmful gas) when burned, so it is generally used.
Production of various industrial blister trays. PVC hard film has moderate toughness and is not easy to burn. It will produce chlorine when burned, which will have a certain impact on the environment. PVC is easy to heat and can be sealed with a sealing machine and a high-frequency machine. It is the main raw material for the production of transparent blister products. PET hard film has good toughness, high transparency, easy to burn, and does not produce harmful gas when burned. It is an environmentally friendly material, but the price is high, and it is suitable for high-end blister products. The blister blister of European and American countries generally requires the use of PET hard film, but It is not easy to heat seal, which brings great difficulties to packaging. In order to solve this problem, people compound a layer of PVC film on the surface of PET, named PETG rigid sheet, but the price is higher
