RE:If woven bags use filler material ,how to pay attention to

The implementation of the new national standard, cancel the requirements of the weight of woven bags, replaced by the assessment of its strength (tensile load), the use of filling the masterbatch when the strength to ensure that the flat wire of the premise of the standard, and extensive use of filled masterbatch or use Low-grade filling of the masterbatch is bound to the quality of woven bags have an impact, and even affect the strength of flat silk and the overall strength of woven bags.

The new national standard in the appendix on the technical specifications of the flat wire is recommended for the elongation at break 15-30%, linear density deviation of + -10%, but the elimination of the relative tensile load, the strength of the requirements of the bag to focus on the The overall performance requirements of woven bags. At present, we use a lot of filling masterbatch, choose which is suitable, which is not suitable, but also need to pass our practice test, but also hope that many manufacturers of woven bags to pay more attention.

Functional masterbatch and modified masterbatch on the impact of woven bags are different, according to their own needs to choose different types and nature of the masterbatch is very critical, pay attention to the relevant matters is inevitable.
