Application of thermal cellophane roll in printing and packaging industry
Thermal cellophane are thin plastics made on the basis of polypropylene, which have a low melting temperature. It can be said that this type of cellophane is considered one of the important and practical equipments and necessities in the printing and packaging industry. Thermal cellophane roll is known as one of the most widely used cellophanes. This cellophane has high resistance to high temperature and with The increase in temperature does not tear.
Thermal cellophane with a thickness of 25 microns acts as a protective layer in the printing and packaging industry.
Types of thermal cellophane according to their material and structure
PVC-based thermal cellophane: The suitable temperature for this cellophane to shrink is above 20 degrees. This cellophane is drier and brighter than other types of thermal cellophane. The use of thermal cellophane rolls based on PVC is in the packaging of bottles and small containers and electronic components.
thermal cellophane based on pof or polyolefin: the material of this type of thermal cellophane is compared to thermal cellophane based on The PVC base is softer and has more elasticity. Also, this type of thermal cellophane has a higher price than PVC-based thermal cellophane. This cellophane can be used to package items that are in direct contact with food. can't These products also have matte, glossy, patterned, velvet, embossed and metallized samples and are produced in different widths. Since this cellophane is known as an industrial product, it is produced in high quantities. Following this feature, the overhead costs of printing houses for buying matte and glossy thermal cellophane rolls will be reduced.
