It is used in extrusion composite production of plastics, plastic/aluminum foil composite films, etc., especially for hot-melt production of battery packaging films.
The equipment adopts the chaotic mixing extrusion technology, multi-layer co-extrusion technology, high peel strength technology of "Huilong" company, etc.
More energy-saving: instead of using blown polypropylene base material, multi-layer co-extrusion is used to shorten the process flow;
High precision: precisely control the temperature of post-heating treatment, so that the composite film containing 40μm aluminum foil is completely wrinkle-free;
High peel strength: The peel strength of the composite film can reach 16N/15mm, which fully meets the packaging requirements of power batteries;
Aluminum foil passivation (coating machine) - nylon and aluminum foil dry compound PA/dr/AL (dry compound machine) - nylon/aluminum foil compound film and CPP film extrusion compound PA/dr/AL/exMPP/CPP, nylon/aluminum foil Composite film and CPP film co-extrusion composite PA/dr/AL/co-exMPP-PP/CPP, nylon/aluminum foil composite film multi-layer co-extrusion coating PA/dr/AL/co-exMPP-PP (extrusion laminating machine).
