JWELL BOPP Double Side Lamination Machine With Autoregistration System


JWELL BOPP double side lamination machine with autoregistration system uses plastic extrusion to laminate coil surfaces or combine multiple substrates, improving tensile strength and moisture resistance. It produces center-seam composite bags with side, flat or self-sealing valve mouths, paper-plastic center-seam bags and BOPP center-seam bags.
Key Selling Points
- Dual Extrusion and Lamination: Double extruder and double lamination units coat both sides of the film in one pass.
- Autoregistration System: Latest double-side color-film autoregistration aligns front and back patterns more accurately at higher speed with simpler operation and fewer operators.
- Bag Strength and Barrier: Lamination raises tensile strength and moisture-proof performance of woven and paper-plastic bags.
- Wide End-Use Coverage: Suited to chemical, fertilizer, cement, rice, sugar, aquatic-product and pet-food bags as well as paper laminating.
- Compatible Substrates: Works with PP and HDPE woven fabrics, non-woven fabrics, paper and related webs.

Application Scenario
Widely used for chemical, fertilizer and cement bags in the chemical and metallurgical industries; rice and sugar bags in food packing; aquatic-product and pet-feed bags; and related paper laminating applications.
Product Description
The line laminates the surface of coiled substrate or combines multiple base materials through plastic extrusion to improve tensile strength and moisture-proof performance. Configurations support center-seam composite bags with side, flat or self-sealing valve mouths, as well as paper-plastic and BOPP center-seam bags.
With dual extruders and dual laminators, both sides can be finished in a single pass. The autoregistration system keeps front and back color patterns aligned at higher line speed while reducing operator workload.
