PE film is adopted to connect sealing strips and form a closed loop.

May/03/2026

This uses PE film to joint the sealing strips, bonding the strips end to end into a ring shape.

Align both ends of the sealing strip closely without misalignment.

Attach PE film in the middle with proper tightness to avoid deformation or falling off.

Keep the joint surface clean, free of dust, oil and impurities.

Control heating temperature, pressure and time to prevent damage to PE film and strips.

Ensure the finished ring is flat, no distortion or twisting.

Press the joint firmly to guarantee strong adhesion and no cracking.

Keep neat appearance, no wrinkles, bubbles or burrs.
