This article details the manufacturing steps of BOPP transparent tape, from resin melting and extrusion to biaxial orientation, adhesive coating, and slitting, emphasizing the importance of quality control.
The production process begins with polypropylene resin, which is melted and extruded through a flat die to form a thick sheet.
This sheet then undergoes a biaxial orientation process, where it is stretched in both the machine direction and the transverse direction simultaneously.
This stretching aligns the polymer chains, enhancing the tape's strength, clarity, and dimensional stability. After orientation, the film is coated with an adhesive layer, typically an acrylic-based adhesive.
The adhesive is carefully formulated to provide the right balance of tackiness and peel strength. Once coated, the tape is slit into various widths according to market demands.
Quality control is crucial at every stage, ensuring that the tape meets standards for thickness, adhesion, and transparency. Summary: This article details the manufacturing steps of BOPP transparent tape, from resin melting and extrusion to biaxial orientation, adhesive coating, and slitting, emphasizing the importance of quality control.
