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 are 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 packaging.
The heat-shrinkable membrane plastic is widely used recent years with the advantage of its transparency, multiple variety, abound raw materials ease of producing and using. It is required that the heat_shrinkable membrane plastic be stable under normal temperature and shrink when heated.
The characteristics of the heat-shrinkable membrane plastic:
1. The transparency help to present the figure of the product.
2. Intensive and firm, prevent from the flow ability.
3. Small package capacity reduce the storage and shipment cost.
4. Shower-proof, damp-pre of and anti-fungus.
5. Healthy and ease of cleaning.
6. Non-prevention of fake and burglary.
7. Various specification of membrane and wide choices.
8. Recycle.
