    PVDC Plastic Film Performance Introduction and Testing Equipment PVDC is an ideal packaging material
    with high barrier, high toughness, low temperature heat sealing, heat shrinkage and chemical stability.

    Due to its moisture resistance, oxygen resistance, moisture resistance, acid and alkali resistance, oil resistance and resistance to various chemical solvents, it has been widely used in food, medicine, military (separation) packaging in the field of packaging
    for more than 50 years.

    PVDC is a thermoplastic polymer with a softening temperature of 160-200 °C, with a linear relationship polymer chain structure
    connected from end to end.

    Its intermolecular cohesion is strong, the crystallinity is high, the chlorine atom in the PVDC molecule is hydrophobic, it will not develop to form a hydrogen bond, and it is difficult to move in the oxygen molecule and the water molecule PVDC molecule, thus making it have excellent oxygen resistance and moisture resistance, and the oxygen resistance performance is not affected by the relative humidity of
    the surrounding living environment.

    That is to say, under any operating temperature or humidity control conditions, PVDC has both excellent ability to block water vapor, oxygen, odor and fragrance, and is currently recognized by society as a comprehensive packaging design material in terms
    of barrier.

    The use of PVDC's gas barrier can effectively delay the occurrence of food oxidation and deterioration problems, greatly increase the shelf life of the extended product, and at the same time avoid the loss of fragrance of the contents and prevent the intrusion of external bad odors; Using its moisture resistance, it can prevent the phenomenon of water loss and drying, poor taste, and will not damage the packaging prototype
    due to water absorption of the product.

    The gas resistance will not change with the change of humidity in the surrounding environment, and even the high humidity environment will not directly cause the deterioration of related products; With its low permeability, it prevents loss of fragrance and does not absorb residual odors and abnormal tastes, providing guaranteed odor integrity
    .

    And can withstand 125 °C/ 30min cooking
    .

    Excellent weather resistance, even if exposed to the outdoors for a long time, direct sunlight, will not be due to the occurrence of packaging fading and aging phenomenon
    .

    , and meets the requirements
    of the national food production sanitation service.

    The main application areas of PVDC plastic film include: cheese, soup, snacks, cooking bags, medical packaging, dry food industry packaging, biscuits and cereals, pet health food, stretched upper and lower film, sauces, meat products, liquid packaging, soy product packaging, e-commerce product brand packaging, chemical packaging and other fields
    .

    Labthink Languang is committed to helping customers cope with packaging problems through packaging testing technology improvement and testing instrument research and development, and helping the quality and safety
    of packaging-related industries.

    Focusing on the field of packaging testing, constantly exploring technological innovation, with more than 200 specialized (separation) technologies, has made a major breakthrough in "independent core sensor technology", and formed a product group with C series as the core, covering performance tests such as oxygen permeability, breathability, moisture permeability, mechanics, heat sealing, heat viscosity, heat shrinkage, friction coefficient, thickness measurement, impact, sealing leakage, top air analysis, viscosity, rubbing and other performance tests
