State-of-the-art Multilayer Technology Realizing Desired Colors and Shapes.
This product is co-extruded functional blown film with a wide range of grade designs and specific functionalities (high strength and coloration) to meet customers' specific requests.
Films used as a sealant base material in bag-in-box or liquid packaging need to have especially strong anti-pinhole properties to prevent bursting and leakage. The Gelbo tester (pictured right) is used for testing these strict requirements. The Gelbo tester applies thousands of horizontal torsions to films and sprays them with dyeing liquid to check the film strength and anti-pinhole properties. This helps provide a stable and high-quality product design.
