What is the meaning of how many strands of pvc bags, and what factors are related to the strength of
What does pvc bag how much silk mean
The number of threads in PVC bags is a description of the strength of PVC bags. In the process of producing PVC bags, the thickness of the PVC bag is measured and described as several strands. Each filament is equivalent to 0.01 mm, so the higher the filament, the thicker and stronger the PVC bag. For example, the thickness of a 5-wire PVC bag is 0.05 mm, and the thickness of an 8-wire PVC bag is 0.08 mm.
What factors are related to the strength of pvc bags?
The strength of PVC bags is affected by many factors, including the type of material, the quality of raw materials, the production process, the size and shape.
Material type: Different types of plastic materials have different molecular structures and physical properties, resulting in differences in tensile strength. For example, the tensile strength of polyethylene bags and polypropylene bags of the same size will be different.
Raw material quality: Even if it is the same kind of plastic material, the quality of raw materials produced by different manufacturers is different, and the better quality raw materials can ensure the tensile strength of plastic bags is higher.
Production process: Processing methods, temperature, pressure and other factors in the production process will also affect the tensile strength.
Size and shape: plastic bags of different sizes will have different tensile strength under the same stretching conditions. In addition, the shape and processing method of the bag mouth will also affect the tensile strength.
To sum up, manufacturers should strengthen quality control and strictly abide by the test standards to ensure that the tensile strength of plastic bags meets the relevant standards.
