Heat shrinkable film label transportation and storage stability

Heat shrinkable film label transportation and storage stability Release time: 2019-06-20 Since PET hardly shrinks below 60°C, its transportation stability is very high, and it is more stable than PVC, and there is no problem with long-distance shipping. . However, OPS has a certain natural shrinkage rate, so its transportation process generally requires thermal insulation measures, such as foam insulation, or refrigerated trucks, and generally the width of OPS film when leaving the factory requires a deviation of 2mm to prepare for it. Natural shrinkage. According to Coating Online, at present, the storage period of the film promised by the PET supplier is 6 months from the date of production, while the storage period promised by the OPS supplier is 3 months from the date of delivery. The PET film is stored for a long time. Later, it will lead to unstable fastness of the palms together and decrease of physical and chemical indicators such as tensile strength; OPS will cause the film to become brittle and unable to be printed at high speed, and the shrinkage rate will decrease or be unstable. At present, PVC and OPS are required to be stored in air-conditioned warehouses in summer, while PET does not have such mandatory requirements.
