Ton bag base fabric is one of the main materials used to make flexible container bags.The following is a detailed introduction to the ton bag base fabric:
1.Material
There are two main materials for ton bag base fabric:polypropylene and polyethylene.
Polypropylene:Polypropylene is a thermoplastic resin made by polymerizing propylene,which is non-toxic,odorless,and tasteless.It has a light density and is currently one of the lightest varieties among all plastics.It has good heat resistance,can be disinfected and sterilized at temperatures above 100℃,and does not deform at 150℃without external force.In addition,polypropylene is particularly stable to water and has a low water absorption rate.
Polyethylene:Polyethylene is generally a thermoplastic resin made by polymerizing ethylene,which also has the characteristics of odorless and non-toxic,and feels like wax.Polyethylene has excellent low temperature resistance,with low operating temperatures ranging from-100℃to-70℃.High density polyethylene also has high temperature resistance,oil resistance,steam permeability resistance,and environmental stress cracking resistance.In addition,it has good electrical insulation,impact resistance,and cold resistance.
2.Production process
The production process of ton bag fabric mainly includes raw material preparation,drawing,weaving,and finished fabric processing.
Raw material preparation:Mix polypropylene or polyethylene raw material particles with auxiliary materials evenly.
Drawing:Melt and extrude plastic film from evenly mixed raw materials through an extruder,and cut it into silk.
Weaving:Stretching the cut silk to produce high-strength,low elongation raw silk through heat setting,and then weaving,coating,and other processes to make the base fabric of plastic woven fabric.
Finished fabric processing:Conduct tensile and elongation tests on the woven ton bag fabric to ensure quality compliance.
3、Purpose:
Ton bag base fabric is mainly used to make flexible container bags,which have the characteristics of large volume,light weight,and easy loading and unloading.They are commonly used for transporting bulk powder and block materials,such as grains,beans,dry goods,mineral sands,chemical products,etc.In addition,depending on the material,there are different requirements for the sealing of the container bag.Therefore,when designing the container bag,it is necessary to fully consider the influence of the base fabric laminating process and sewing process on the sealing.
In summary,as a key material for making flexible container bags,ton bag base fabric has strict requirements and standards in material selection,production process,and application.
