Applications

PET/PP Strap extrusion machine is used for producing pet and pp strap from recycled material. With the characteristics of high anti-tension force 、small elongation and low cost, pet and pp are recognized the new environmental strapping material to substitute for steel strap in the international market.

Characteristics

» PET raw materials do not need dry and water treatment separately. There is an automatic circulation on preheating and drying, which saves lots of equipment investment and reduces the production cost by 30%

» Uses the recycling bottle slices as raw materials directly, which reduces the course of raw material-making.

» With the multi-purpose machine, it can produce straps in different specifications directly and doesn't need to change the mould head.

» The products has the same transparency as made from new polyester slices, but the tensile strength and shock resistance are stronger.

» Low energy consumption, high production capability.

» Easy to operate, saves manpower: 2 people for one production line on average.
