China Flexo Printing Machine

High polymer materials such as rubber, plastic and fiber will have a certain shrinkage under a certain temperature. Most products are required to have a good thermal stability and small shrinkage, but some products ate required to have a large shrinkage when heated. The performance that high polymer materials will shrink by heating is opposite to that of metal materials. Taking advantage of this performance. We make the high polymer materials into heat-shrinkable rubber boot, heat-shrinkable membrane plastic, heat-shrinkable fiber and fiber-knitting which will be used for packging.
The heat-shrinkable membrane plastic is widely used recent years with the advantage of its transpatency, multiple variety, abound raw materials, ease of producing and using, The table 1 shows the main performance and the application of the heat-shrinkable membtane plastic.
Besides the variety in table 1, , PA, PA, PET, PVCD, EVA etc also can be made into the heat-shrinkable membrane plastic, it is requirded that the hea-shrinkable membrane plastic be stable under normal temperature and shrink when heated. The characteristics of the heat-shrinkable membrane plastic: The transpatency help to present the figure of the product. Intensive and firm, prevent from the flowability. Small package capacilty reduce the storage and shipment cost. Shower-proof, damp-proof and anti-fungus. Healthy and ease of clearing. Nonrelease, ensure the prevention of fake and burglary. Various specification of membrane and wide choices. Recycle used and do no harm to the environment.
