Advantages of Plastic Strapping

PET strap is recognized a new environment protective strapping material to substitute for Steel Strap &PP Strap in the ruling international market. They are not only the aggregation of the intensity and the tenacity of steel strap, but also overcome the disadvantage of the tradition packing material such as insufficient intensity, brittle and so on. At present, they have been applied in wood, steel and so on.
Adopts advanced dehumidify dryer system. It makes sure the material humidity at 80PPM at 50PPM dew point. Meanwhile, it compact material and increase the viscidity.
Adopts closed cycle transport system after dryer to avoid contact with outside air and make sure the material drying continuously.
Extruder adopts special screw for PET. The screw has unique separate and mix property to make sure uniform plasticizing. The screw is suitable for recycled PET bottle flakes, PET mixture and original PET material. And the extruder adopts ration forced feeding to make sure the stable extruding. It makes sure the product uniform.
Produce different model product at one die and mould, adopting hydraulic screen exchanger without material leak.
Static cooling roller replaces the water cooling tank. The roller will cool the strap at the constant temperature. It improves the product's stretch intensity.
The strap after formed will be warm and anneal treated to wipe off the part stress remained after stretch. It makes molecule tropism be steady to avoid strap distortion caused by storage.
The winder adopts double work position and auto-meter. It is easy operation and convenient coil change.
Centralized electrical control, PLC self-correcting control make it is easy operate.

PET and PP strap making machine introduction

• Pre crystallization drying unit

As PET is easy to absorb moisture in the air, it must be fully dried. At the same time, in order to prevent bonding during drying, crystallization equipment needs to be configured. PP strap not need it.

• Single Screw Extruder

Always PET two straps extrusion needs 90/30 single screw extruder.
PP two straps extrusion needs 75/30 single screw extruder.
Special design screw structurer could extrude PET PP materials smoothl,it does not create excessive shear molecular structure, and ensures the strength of the packing belt

• Filter, Melt Pumb, Exrusion Die Unit

It is controlled by PLC pressure closed loop control system. The pressure sensor will transmit signals, and PLC is used to control the speed of melt pump and extruder, so as to stabilize the extrusion of PET or PP materials

• Water tank with first haul off rollers

PET is Length 4000mm, PP 2000mm.
It is stainless steel materials.
The water is heated by water tank heating unit
The haul off rollers is five rollers, working to take PET or PP strap materials out of water tank

• The stretching oven

The oven is heated by electric power. Heating air is spread evenly by fans.
In the oven, the PET and PP strap will be stretched first time.

• Stretching rollers

This device is working for PET strap second time stretching.
PP strap not need stretching.

• Embossing Roller

This 38Crmoal materials, high surface hardness rollers do embossing

• Annealing oven and cooling tank

As PET and PP materials has high deformation prestress after stretching. It has to do annealing and water cooling to fix the size.

• Three rollers puller

It is working to take the materials out of annealing oven and cooling tank before winders

• Automatic Winder

The winder could be designed into servo motor unit, inverter motor unit and torque motor according PET or PP materials.

The unique back tooth shaft is used to make the packing belts neatly arranged without overlapping and no horn shape, so that the packing belts maintain a good straightness, which is more suitable for the use of automatic packing machines, and ensures that the automatic equipment conveyor belts are in place. Do not drop the belt.
