7. Manufacture of other composite flexible packaging materials
Process principle and structure composition of laminating machine
Process principle
Extrusion casting molding: plastic particles are extruded linearly from a flat die after being plasticized by a screw, and then attached to the surface of flexible substrates such as paper, film, non-woven fabric, woven fabric, etc. after being stretched, and then cooled, shaped and compressed. A composite material that combines the barrier properties and heat sealability of the plastic film layer, the strength and toughness of the substrate, and the functional characteristics.
Structure and composition
The whole machine is composed of feeding device, extruder main machine, die, unwinding mechanism, compound mechanism, winding mechanism, edge position control device, trimming device, heating and cooling system, electrical measurement and control system and other parts. According to the needs of different products, the second unwinding mechanism, printing equipment, oven, substrate surface treatment device (corona machine, etc.), online thickness gauge and other components can be added. Front process equipment: granulator, printing machine or other equipment; back process equipment: slitting machine or other equipment.
