In solventless lamination workshop, there are two solventless laminators, which support an annual production capacity of 20,000T. Meanwhile, products manufactured with solventless laminator enjoy high lamination strength and no residual solvent. Therefore, diverse materials could be laminated here, especially for food packaging bags.

7-layer cast stretch film co-extrusion line could be used to co-extrude diverse resins, such as EVOH (Ethylene vinyl alcohol), PA (polyamide), PP (Polypropylene), PE (Polyethylene) and so on. With the equipment, the strengths from diverse plastic materials are combined together, which well avoids the generation of residual solvent during lamination of two materials with glues.
