The production process of cold-applied tape typically includes the following main steps:

1. Base Film Extrusion

   • Raw Material Preparation: Polyethylene (PE) is prepared as the base film raw material.

   • Extrusion Molding: The raw material is heated and melted in an extruder, then molded through a die to form a continuous base film.

   • Cooling and Shaping: The extruded base film is cooled and shaped using cooling rollers to ensure uniform thickness and consistency.

2. Adhesive Coating

   • Adhesive Preparation: Butyl rubber are prepared to ensure proper viscosity and stability.

   • Coating Process: The adhesive is evenly applied to one or both sides of the base film using coating equipment to form an adhesive layer.

3. Slitting

   • Slitting Preparation: The coated base film roll is prepared, and the parameters of the slitting equipment are adjusted.

   • Slitting Operation: The wide roll is slit into cold-applied tapes of the required width using slitting equipment.

   • Winding and Packaging: The slit cold-applied tapes are wound into rolls, packaged, and prepared for shipment.
