Production for blowing film / bag

Raw material and additive mixtures are melted through high-temperature, then the machine blows out the product through T-Die just like blowing a chewing gum. Production operator controls airflow to decide film thickness and minimize thickness tolerance, also control width and length. PE bag / film cools down through guiding roller and finally winding on to PVC tube to become a finished product.

During production and Examination

Production operator conducts inspection during production regularly to make sure product is within our in-plant standards. Before shipping, QC executes a final check-up on thickness, width, length, and appearance according to ISO 9001:2015 standard.
