How Shrink Film Restores Shrinkage
When manufacturing heat shrink film, the pre-row heating well is stretched in that direction, and then the inkstone becomes cold and the chain molecules are aligned in the direction of stretching. This film will be heated to the claustrophobic state when stretched again, the chain molecules will return to the original disorderly state, and the thin size will return to the size before stretching, thus the shrinkage recovery phenomenon occurs. Heat-shrinkable sets are mainly printed by gravure, and the printing book is brightly colored and well-saturated. Can be done to stick on the packaging container decoration, highlight the appearance of goods, improve the appearance of decorative goods, and produce a very good shelf effect.
Add melt extrusion on the extruder, cast through the die cold roller, then heat the die in the appropriate temperature range above the glass transition temperature and below the melt temperature, and stretch under external force for one-way or two-way drainage, which generally requires a lateral 3.5 to 4.0 times stretching. The stretching causes the PET polymer chains to face in the direction of the external force and then cools to freeze the oriented PET molecular structure.
