Raw Material Preparation
The production of PVC film begins with PVC resin powder as its primary raw material. To tailor its performance for specific applications, a range of key additives-such as Lubricant, stabilizers, and Processing modifiers,Impact Modifier,Pigment-are precisely blended into the resin mix.
Mixing
The process begins with feeding PVC resin and selected additives into a high-speed rotating mixer. Under controlled conditions, the materials are thoroughly blended into a uniform dry mix before being cooled and stabilized for the next production phase.
Extrusion Plasticization
The homogenous blend is then fed into an automated extrusion system. Within the extruder barrel, the material is progressively heated, pressurized, and plasticated-transforming it into a uniform molten state-before being continuously extruded through a precision die.
Calendering Molding
Following extrusion, the continuous PVC melt is immediately fed into a precision calendering unit. Here, it passes through a series of heated counter-rotating rollers that precisely gauge, smooth, and solidify the material into a sheet of uniform thickness and surface quality.
Cooling And Peeling
After the calendered sheet is cooled and set to its final dimensions, it is smoothly stripped from the last cooling roller. The continuous film is then guided through tension controls and cleanly wound onto large core-based reels, ready for inspection and further processing.
Partitioning
Using computer-controlled equipment, the wide film is accurately cut and rewound into narrower rolls of specific widths and lengths according to each customer's order specifications.
Packaging
Once cut to size, the finished rolls are carefully prepared for shipment. They are packaged following standardized procedures-using PE inner bag, kraft paper outer layer on pallet-to ensure they arrive in perfect condition. The packaged goods are then logged and stored in our warehouse, ready for dispatch according to the delivery schedule.
