The even thickness control on the Polystar extruders make sure that the fi lm rolls produced are well-prepared for the process that follow – it makes the bag making/converting and printing process much easier. “The bag making ma- chines can seal better, and we have less defected prod- ucts as a result,” Mr. Bai added. “When our customers are happy, we are happier.” 100% export, 100% Polystar The public-listed company located in Dong Nai province, who has invested in more than 30 sets of Polystar since 2016, has designed its new factories for 100% export pur- poses. It focuses on various products including draw tape garbage bags, star-sealed, bag-on-roll, T-shirt and shop- ping bags, exporting 100% to Europe, Australia and the US. “We are very proud to show our international buyers the machines when they visit our factory,” said Ms. Thao, marketing manager of the draw-tape garbage bag pro- ducer. “Polystar is a global brand that is also well known in the countries where we export our products to. During the factory tours, our customers recognize that we have invested in quality machines, this helps them understand our commitment in product quality and why we should be their valuable long-term partner and supplier,” she added. “The machines cover a wide range of products that we need to produce,” said Mr. Su, technical director of the factories dedicated for export products. “HDPE, LDPE, LLDPE, virgin, recycled or CaCO 3 , you name it, we use only Polystar extruders for our export products because it produces the quality our customers need,” he explained.
