Due to the working environment of the heat shrinking machine, it is required to withstand high temperature and high gas permeability. Therefore, the PTFE (Teflon) mesh belt has been widely used due to its own advantages. PTFE (Teflon) mesh belt can be called a heat shrinkable mesh belt or a film wrapping machine belt.

Application and attention of PTFE (Teflon) mesh belt on heat shrink packaging machine

The normal size of mesh: 1*1mm, 2*2.5mm, 4*4mm, 10*10mm; The normal color: brown and black. Comprehensive comparison, we recommend to choose our 4*4mm mesh belt, because we are using the double-twisted double-grain fiberglass mesh to impregnate the PTFE (Teflon) emulsion, the color is brown, the quality is good, and the price is relatively cheap.

Another point of attention related to the use of the mesh belt is that the machine must be installed horizontally, otherwise the service life of the electric heating tube will be shortened; for the machine with the conveyor belt, the inclined installation will cause the conveyor belt to deviate from the center and shorten the service life of the mesh belt.

PTFE (Teflon) mesh belt is made of PTFE emulsion and impregnated with high-performance glass fiber mesh. It is a high performance, multi-purpose composite product, and it’s widely used in paper, food, environmental protection, printing and dyeing, clothing, chemicals, glass, medicine, electronics, insulation, grinding wheel slicing, machinery and other fields.

Teflon mesh belt features

1. Temperature resistance -70℃ to 260℃, weather resistance and anti-aging. After 200 days at 250℃, the strength and weight of the belt are kept the same.
2.Non stick: not easy to stick any substance. It is easy to clean, all adhesive substances such as paste, resin, paint, etc. can be easily removed.
3. Chemical corrosion resistance, which can withstand the corrosion of strong acid, alkali, aqua regia and other organic solvents.
4. Good dimensional stability (extension coefficient less than 5‰) and high strength.
5. Anti-bending fatigue.
6. Non-toxic.
7. Fire retardant.
8. Reducing the heat source cost and improving the drying efficiency.
