Seam Tape PVC for Inflatables

Technical Parameters

Material Selection Guide

The choice of seam tape depends on the application's required durability and the base material's coating type.

• Base Fabric Match: Ensure the tape formulation (color and finish) matches the base fabric of the inflatable product for visual consistency.

• Application Method: For solvent-based repair, a slightly thicker tape (0.70mm) can offer more material for dissolution and rebonding.

• Width Consideration: Standard 5cm or 10cm widths are common, but wider tapes offer more surface area for structural reinforcement.

Manufacturing and Tailoring

The production focuses on precise calendering and high-accuracy slitting.

• Slitting Precision: We use high-precision slitting equipment to ensure consistent width and perfectly straight edges, which are critical for smooth application during automated seam sealing.

• Core Selection: Tapes are wound onto small, lightweight cores for ease of handling in both factory and field repair kit environments.

• Formulation Traceability: Each tape roll is traceable back to the batch of raw materials used to ensure formulation consistency for optimal welding performance.

Deployment FAQ

• Q: Does the seam tape formulation contain any adhesive on the back?

  A: No, this is unreinforced PVC film. It acts as the welding material and requires a heat source (hot air or HF welder) to melt and fuse it to the base fabric, or a dedicated solvent cement for chemical welding.

• Q: Is the tape resistant to UV degradation when used externally?

  A: Yes, the tape is formulated with the same UV inhibitors as our external-grade fabrics to ensure the seal does not prematurely degrade or harden under sunlight.
