Description

PP plastic packing strip belt making machines, PP PET strapping band extrusion machine

PET packing strip is widely used in packing applications, it can replaced the steel strap for packing application, as its good tensile strength, flexible, low prolongation rate, good performance of high temperature resistant, non-rustiness, and low use-cost, etc, it is used in steel, construction material, chemical fiber, paper making, tobacco, agriculture, election, etc.

PP PET packing strap band extrusion machine features
Screw with compression ratio especially for PP/PET, gradually changing diameter and deeper thread groove at the melting part;

Gearbox with hardened gears; Die can be precisely adjusted to ensure stable production and smooth surface of straps;

Stainless steel cooling trough with four thermo treatment processes displaces the traditional one;

Haul off rollers with bigger size ensure the quality of products;

New rolling technology overcomes the shortcomings of traditional rolling machine like high gradient and bending delection;

Laser embossing roller makes clear and even patterns.

Advantage of Wedo PP PET packing strip belt making machine

1.Special design of the screw extrusion technology can be choosing as per customer needs.

2.Can process 100% recycled PP/PET bottle flakes or pellets.

3.Plasticization and stable extrusion can with PLC automatic control for the full line.

4.According different requirements, changing materials for make strap have better and special function. For example, the strap for packing cotton can be from enhancing the breaking strength and joint strength when welding strap.

5.Melt filter with two pistons with air venting design and back flushing.

6.Number of strap:1,2,4,6,Width: 5mm-22mm,Thickness: 0.5mm-1.5mm

7.Workers: 2 -3 workers per shift, 12 hours/shift.

PP PET packing strap belting extrusion machine include:
1, The raw material will be dried by the dehumidifier, and the below 40 dew point make the material humidity less than 40PPM, and condensation polymerization(this is for PET straping line);
2, The conveyor of the raw is in a enclosed and circular mode, and without contacting with the air, in order to made perfect effect of drying;
3, Special designed extruder screw for PP/PET production, bear the better performance of material separating and mixing. Automatic material feeding provide the smooth environment for the PP/PET strap production.
4, Special designed extrusion die & mould; And the improved screen changer realize non-stop screen changing, and without material leakage; Wedo also equitp the melting pump to ensure the packing strap material out more everage.
5, Water tank cooling the PET strap band. The steady water temperature enhance of the molecular tension strength(better equip water chiller);
6, Heating cabinet is used for thermal annealing, relief the band distortion after long-time storage;
7, Double-station automatic winder, easy operation; We provide our worldwide customer the turn-key project. We will assist our customer from the installation to the final production of this line.
