Look at the practical characteristics of heat shrinkable film labels for beverage bottles

Heat shrinkable film labels: film labels are widely used in food, beverage, cosmetics, packaging and other fields in shopping malls. The plastic film is stretched in a highly elastic state, and the stretch is frozen after cooling. When heated, the plastic film has a tendency to restore the size before stretching. This so-called 'elastic memory' is a heat shrinkable film. Many customers have adopted our heat shrinkable film labels for beverage bottles, and all have used them. Among them, there is a lot of demand for beverage shrinkable film, you can come and see. The most common material used for heat shrinkable film labels is PVC resin. Heat shrinkable film PVC characteristics: (1) PVC resin is a colorless, bromine-free, odorless white powder. (2) The glass transition temperature is 87°C, and the melting temperature is 210°C. It starts to decompose at 100°C, and decomposes rapidly when the temperature is u003e130°C. (3) PVC itself is non-toxic, but its monomer vinyl chloride is very toxic. The US FDA stipulates that in PVC resin, the content of VCM is less than 1mg/kg as non-toxic PVC, which can be directly contacted with food and medicine. (4) It is a typical heat-sensitive thermoplastic. (5) Excellent chemical resistance. (6) Self-extinguishing, self-extinguishing away from the fire. (7) Excellent electrical insulation performance. (8) Excellent transparency. The use temperature of PVC is below 80℃, and it can withstand any concentration of hydrochloric acid at room temperature, resistant to less than 90% of sulfuric acid, 50% to 60% of nitric acid and less than 20% of caustic soda; it has excellent oil resistance and can withstand various alcohols; Soluble in ketone solutions. (9) Not resistant to γ-ray irradiation.
