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.
