The storage conditions of PVC for blister packaging mainly include the following aspects:
Temperature: PVC materials should be kept in a cool and dry environment during storage, and the temperature should be below 30℃. Excessive temperature will cause the PVC material to soften and deform, affecting its performance and service life.
Humidity: PVC materials should be stored in an environment with a relative humidity of 45%-75% to prevent the material from hygroscopic expansion or drying and brittleness. Excessive humidity will cause water mist, mildew spots and other problems on the surface of PVC, while low humidity will make PVC dry and brittle.
Light: PVC materials should avoid direct sunlight, because the ultraviolet rays in the sun will accelerate its aging process, causing the material to discolor and become brittle. Therefore, it should be stored in a dark place to prevent direct exposure to sunlight.
Ventilation: PVC materials should be stored in a well-ventilated environment, keep air circulation, avoid moisture and deformation. Poor ventilation will cause the material to become damp and moldy, affecting its physical properties and service life.
Moisture-proof: PVC materials should be stored in an environment with moisture-proof measures. Double-layer packaging bags or desiccant can be used to prevent moisture from affecting the materials.
Keep away from heat and fire sources: PVC materials should be kept away from heat and fire sources, and avoid direct contact with high-temperature objects to prevent fire or material deformation.
Avoid contact with sharp objects and strong acids and alkalis: PVC materials should avoid contact with sharp objects and strong acids and alkalis to prevent scratches or corrosion.
