    With the aggravation of aging and the improvement of people's consumption level, the market demand for medicines shows a growing trend

    .

    In 2021, the global pharmaceutical packaging industry market scale will reach 100 billion US dollars, and China's pharmaceutical packaging industry will exceed 100 billion yuan
    .

       Pharmaceutical packaging refers to a processing process that uses appropriate materials or containers and packaging technology to divide (fill), package and other semi-finished or finished pharmaceutical preparations to provide quality assurance, identification of trademarks and descriptions for drugs
    .

       In addition to the strong development of medical supplies themselves, the packaging of medical supplies is also developing rapidly.
    According to a survey by Freedonia, a US market research company, the demand for pharmaceutical blister packaging will reach US$4.
    4 billion in 2021

    .

       Several trends in the development of drug packaging Drugs are a special commodity whose efficacy and quality are directly related to human health and safety.
    The packaging materials used not only ensure drug efficacy, but also ensure the reliability and convenience of drug use.
    effect

    .

       It is an industry with increasingly stringent quality requirements, and several trends are expected in the future: Green: Development of new degradable packaging materials
    .

       Environmental adjustment: Change the gas state in the package to ensure the quality of the packaged product for a long time
    .

    For example, there are packages that enclose a desiccant (oxygen absorber) to extend the shelf life of medicines
    .

       Flexible packaging: Thermoformed squeeze blister packs for controlled doses, alternatives to bulk or bottled pharmaceuticals will grow
    .

       High barrier: Use materials with excellent barrier properties to prevent gas, water vapor, odor, light, etc.
    from entering the package to ensure the effectiveness of the drug

    .

    The application of high-barrier packaging has become very common in Europe and Japan
    .

       Sterility: In a sterile environment, instant ultra-high temperature sterilization technology is used to sterilize packaged drugs, and multi-purpose composite materials are packaged through different forms of extrusion and compound molding
    .

       From the performance point of view, medicines are special commodities, and the sealing of the packaging is very important, which can protect the medicines from moisture, ensure the quality and efficacy of the medicines, and also affect the storage period of the medicines
    .

       Moisture is one of the common reasons for unqualified medicines, which is generally caused by poor packaging of medicines and moisture in the process of storage and circulation
    .

    The blister packaging of medicines is one of the most important packaging methods for medicines because of its good airtightness and easy to use and carry
    .

       The materials used in blister packaging are mainly PTP medicinal aluminum foil and plastic hard sheets
    .

    Plastic rigid sheet materials are usually selected from polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) or composite materials
    .

       Polyvinylidene chloride film (PVDC) is a kind of film with good barrier properties, which has barrier properties and chemical stability to oxygen, water vapor, carbon monoxide and organic compounds
    .

    Among the many polymer pharmaceutical packaging materials, only PVDC has high barrier properties to both water vapor and oxygen, and has been widely used in pharmaceutical packaging
    .

       In high-barrier pharmaceutical packaging, it is usually used as a coating material, coating 2-4m PVDC composite film on PP, CPE, PET film, which can play the role of moisture resistance, taste preservation, and moisture resistance
    .

    PVDC is the most common coating in blister packs, it can reduce the breathability and moisture permeability of PVC blister packs by 5-10 times
    .

    The PVDC coating composite film for medicine is used to make high-temperature retort sterilization bags and fresh-keeping antiseptic bags in China
    .

       In the plastic composite film bag packaging of granules, powders, powders, and capsules of traditional Chinese medicine, one of the four main varieties developed is PVDC
    .

       In addition, PVDC also has the properties of acid resistance, alkali resistance, grease resistance, and chemical resistance.
    It can be used under high humidity conditions and is convenient for transportation and storage

    .

       At present, PVDC coating film has been widely used in the packaging of meat products, cakes, tea, and solid beverages, and plays the role of preventing water loss, blocking gas, maintaining fragrance, anti-corrosion, and preserving freshness
