A large portion of woven sacks – 30 to 40 percent – is produced with coating, because coated sacks provide much better protection of the contents from dust and especially from moisture. Coated fabric also offers better printability. However, uncoated sacks are preferred for some applications, especially for filling goods that require breathable fabric.
HEAVEN multi-function Extrusion coating laminating machine is developed continuously by ourselves, based on our production experience of more than Fifteen years. It is characterized by advanced technique, reliable quality, easy to operate, and high automation, which is used widely in the industries of chemical, petrochemical, cement, sugar , salt, Grain and wheat, Animal feed, Commodity items, metallurgy and mining and general purpose packaging, storage and transportation of many kinds of materials. The line uses PP or PE as raw material, through the flow-casting coating and lamination technology, achieving single-sided / double-sided coating or paper-plastic lamination with substrates (plastic woven fabric), to produce coated or laminated products. The line is equipped with advanced electrical and mechanical devices throughout the whole production flow from substrate unwinding, lamination to winding, to achieve single control and group control. The dual-station Unwinder uses automatic web guiding control for substrates, and brakes for surface tension control of substrates, achieving pneumatic splicing and non-stop roll changing. The laminator is equipped with preheating roll (optional) for preheating and drying of substrates. Laminating roll, silicon rubber roll and press roll are of dual-interlayer forced water cooling structure, with excellent cooling effect. The dual-station winder adopts constant-tension surface friction winding, pneumatic transverse cutting, roll changing without shutdown, and equipped with adjustable edge-trimming device, edge-strip blowing device, and length counting device.
