Packaging and storage of polyester masterbatch

Polyester masterbatch products are packaged in double layers, the inner layer is a waterproof and moisture-proof polyethylene film bag, and the outer layer is a paper-plastic composite bag. The standard packaging is 25 kg/bag. Please store it in a ventilated and dry place with a cushion under it to avoid sun and rain. The color quality of the polyester masterbatch can be up to 5 years. After opening the package, the remaining part should be sealed again to prevent dust pollution and moisture absorption.
