The Production of Plastic Strapping

There are various types of plastic strapping.the diagrams contain the production process of  the two most important kinds,namely PP 

and PET.in the case of PP the most important componenet is a granulate of polypropylene;in the case of PET this is a recycled PET material

( for example from PET - bottles or cassettes) .

The raw materials are loaded by a hopper,after which it is forced through a worm wheel.this changes the raw material into a syrup-like substance.

the substance exits a mold as a flat strip,or in multiple strips and is guided through a water bowl for cooling.the material is then reinforced through a water bowl for cooling.the material is then reinforced throug heating.this streching ensures that the molecule are oriented in one direction and is thus the deciding factor for stretch and strength properties of the material.in case of PET,a second stretching is conducted without heating. finally, before rolling up,the strip may be shaped and heated and cooled one last time.this is also called annealing which serves to homogenize the material and to relieve tensions.

Plastic Strapping
 
Plastic strappping materials are made from Polyester,Polypropylene and are available in a variety of strengths,
styles,and finishes.Unlike steel strapping,elongation and recovery are a key factor for deciding which type of
plastic strap to use.
 
Polypropylene Strapping
 
Polypropylene strapping is an economical strapping material compared to other materials.it's designed for light to 
medium duty unitizing,palletizing and bundling.Consistent pressure to polypropylene strapping can result in 
unrecoverable dead stretch and inability to return to its original length.
 
Features and Benefits of Polypropylene Strapping:

•  Economic
• Highest Level of Elongation
• Little Recovery
• Low Strength

PP strap making machine is mainly for producing PP strap.
 
The raw material can be 100% recycled material, which can reduce the produce cost and get a good profit.
 
And The PP bale is the substitution of the steel strap and has a lot of advantages such as good extension, high temperature
resistant, easy use.
 
It is mainly suitable for packaging for various trades.
 
 
Advantage of our machine

•  PP raw materials do not need to separate the dry and water treatment . There are automatic circulation on preheating and

drying that save a large number of equipment investment and reduce the production cost by 30%;
 

• Utilizing the retrieving bottle slice as raw materials that reducing the cost to a great extent;

• With the multi-purpose machine, produce the PP PET straps in different specifications directly and don not need to change the mould head;

•  Comparing with new polyester slice, the transparency of products is just the same, but the tensile strength and shock

resistance are up to the international grade;
 

• Low Energy consumption, but high production capability;

• Easy to operate, save the manpower and two persons for one production line on average
