We are a leading Manufacturer & Exporter of Extrusion Coating Lamination Plant such as Extrusion Coating Lamination Machine, BOPP La Extrusion coating & laminating process .
Coating
The actual process of extrusion coating involves extruding resin from a slot die at temperatures up to 320°C directly onto the moving web which may then passed through a nip consisting of a rubber covered pressure roller and a chrome plated cooling roll. The latter cools the molten film back into the solid state and also imparts the desired finish to the plastic surface. The web is normally run much faster than the speed at which the resin is extruded from the die, creating a coating thickness which is in proportion to the speed ratio and the slot gap.
Application of Extrusion Coating Machine in China:-
Paper coating and laminating
Flexible packaging
Board coating and laminating
Fabric scbrim and non-woven
Laminating
Extrusion laminating is a similar process except that the extruded hot molten resin acts as the bonding medium to a second web of material.
Applications of Extrusion Coating Machine in China:-
Extrusion Coating Machine in India are usually custom-built and can be configured for a variety of applications including liquid packaging, aseptic drink containers, flexible packaging, toothpaste tubes, medical packaging, industrial wraps, insulation backed materials, and plastic coated tablecloths, as well as sacks for products as diverse as cement, cereal grain, and dry chemicals.
Extrusion Coating Machine in India deliver a combined substrate, the component elements of which would be very difficult to separate. The combined substrate inherits highly enhanced physical properties and barrier protection performance from its component elements.
