Heat Shrink Tubes ---- Dual Wall Heat Shrink Tubes

The inner wall of the plastic double-wall heat-shrinkable tube has a layer of hot-melt adhesive, and after heating, the hot-melt adhesive rapidly melts, fills the space of the packaged object, and then the outer polyolefin tightly shrinks, so that the thickness of the heat-shrinkable tube after shrinking obviously increases. , The degree of wear is strengthened. The ordinary heat shrink tube is only a single layer, the inner layer without hot melt adhesive.

General heat-shrink tubing usually only 2:1, with adhesive double-wall heat shrinkable tube with 3:1 and 4:1

The double-wall heat shrinkable tube is more suitable for some irregular products in addition to the sealing and waterproof properties.

Shrinking tools are generally recommended in two ways: 1, choose the oven; 2. use industrial hot air cylinder
