11. Five-roll traction system, the traction is stable, the equipment runs smoothly, the failure rate is reduced, and the maintenance cost is reduced by 60%.
12. High-precision special embossing and pressing device, adjustable pressure, clear and beautiful embossing, improved product quality, comparable to Europe, America, Japan and South Korea.
13. Constant force winding system, unique design parameters, in line with high output, excellent tape winding effect, flat and beautiful section.
14. Wheel and shaft parts are made of high-strength alloy steel. The gears are processed by carburizing, quenching and grinding, and the equipment failure rate is reduced by 60%.
15. Using computer programming control system, automatic memory strapping production specification data, easy to operate, easy to debug.
16. The PP production line has four belts, and the stable production volume reaches 5-6 tons per day! The latest product PP production line has six belts, which is the first in the industry.
17. Optional no-stop automatic screen changer! Maximize benefits.
Production process
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 controled by Pue pressure closed loop control system The pressure sensewi tansmit signals, and Pic is used to control the speed of melt pumnp aneextruder, 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
First five rollers puller
It is working to take the materials out of cooling tank before annealing oven
The stretching oven
The oven is heated by electric power, Heating air is spread evenly by fansin the oven the PeT and Pp strap will be stretched frst 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 and with

1. PET plastic steel strip is a packaging material with good tensile strength and excellent fusion performance.
2. It has excellent tightening and holding ability, and does not loosen for a long time after packaging, thus ensuring excellent impact resistance of goods during long-distance transportation.
3. It can be directly packaged with PET plastic steel strips, and the goods will not be damaged or corroded.
4. Good flexibility, easy and safe operation. PET plastic steel strips do not have sharp edges on the steel strip, which will not scratch the packaging or hurt hands. There is no need for special tools when cutting, and even if tied tightly, they will not hurt people when cut.
5. Excellent weather resistance, maintained between -50 ºC and 100 ºC, with good stability.
6. Beautiful appearance, environmentally friendly, recyclable.
