EVA Film Laminating Line - Case from South America

Nanjing GSmach Equipment Co., Ltd. is a professional manufacturer of plastic laminating equipment with rich experience. A customer from South America needs a film applicator.
This laminator is used to produce products by extrusion casting composite skeleton method by applying a layer of EVA resin on the surface of BOPET web as the base material. The line is an extrusion laminating line and includes the appropriate auxiliary equipment. The end product is the popular EVA bag film, which can be used in a variety of applications.
The general process flow is automatic unwinding - edge correction - corona - coating oven - extrusion lamination - antistatic liquid coating - corona cooling - final winding device.
We utilize a double-station swing-arm active unwind for roll diameters up to 800 mm with controlled tension.
The energy-efficient extrusion screws for EVA are designed for dynamic energy balance, with an equivalent diameter of 75 mm and a maximum extrusion capacity of 100 kg/h.
Our extruder loading platform is electrically driven with a set of guide rails.
T-die: Extrusion thickness uniformity of 5%, die width of 1100mm, max. extrusion width of the final product of 900mm, designed for a machine speed of 160m/min.
Calender adopts three-roller calendering composite machine. It consists of cooling roller, pressurizing roller and back-pressurizing roller. The whole production line is equipped with two ovens.
AC agent vertical coating oven is gluing processed to improve the lamination fastness.
Antistatic liquid coating oven with liquid tank: 800*1600*300mm.
It also includes vulcanization light box with UV irradiation and 6 groups of light treatment for increasing the adhesion of the products.
In our tests, we used both kraft paper and BOPET rolls as substrates, and the tests were very successful and the adhesion quality was uniform.
We are experts in all kinds of laminating machines and warmly welcome your inquiries.
