General description of PET strap making machine

Process flow of PET packaging belt production line:

① feeding→② mixing raw materials→③ raw material pre-drying→④ vacuum dehumidification of raw materials→⑤ raw materials melting extrusion→⑥ material embryo expression(with embryo) cooling molding→⑦oven preheating→⑧first stretching→⑨second stretching→⑩embossing→⑪ oven tempering to set the shape→⑫ cooling → ⑬winding(finished product)

Features of PET packing strap production line

1. Better tensile strength: the PET strap production line has the tensile strength of the steel belt, and the ductility is good, and the anti-impact performance is better. It is not easy to break, and it can ensure the safety of product transportation.
2. Small extension: Although PET strap is one kind of plastics, its extension of change is very small, its elongation is only 1/ 6 of polypropylene, it can maintain tension force, after the packing make the expansion no longer change.
3. Strong temperature resistance: the experiment proved that the melting point of PET packing belt at about 260 ℃, can be used under the environment of 120 ℃ for a long time not to distort,it has a good stability.
4.  Good economic benefit: the density of PET packaging belt is 1.30 ~ 1.38 g/cm3, which is only 1/6 of the steel belt density (7.8 g/cm3), which is equivalent to the length of the 6-ton steel belt, and the price of the same unit length is relatively low.
5. Environmentally friendly: the steel belt will rust due to exposure to the air, and the rust is highly permeable to the packaging. PET packing tape is beautiful and not rusted, but avoid unnecessary worry. It can also be recycled.
6. Good flexibility and safe operation: the PET packing strip has no sharp edge with steel belt, it will not scratch the package, and it will not hurt the hand. You don't need a special tool when you cut it, even if it's tight, it doesn't hurt when you cut it.
7. High quality packaging ideal products: PET packaging with all kinds of bright colors, shiny, high quality, the most ideal packaging products of high-end packaging
