Flame & Water Based lamination
WTEC offers advanced flame and water-based lamination services designed to bond flexible substrates such as PVC, leather, vinyl, and fabric to foam and textile layers with precision, durability, and production efficiency. These lamination techniques are widely adopted in industries where aesthetic finish, mechanical integrity, and comfort performance are critical to product success.
Description
Flame lamination utilizes a controlled open flame to melt the surface of thermoplastic foam—typically polyurethane—creating a tacky bonding layer that adheres instantly to the target substrate. This method eliminates the need for additional adhesives, resulting in a clean, solvent-free bond with excellent peel strength and long-term stability. It is particularly effective for bonding materials in automotive seating, headrests, door trim panels, and cinema or auditorium upholstery, where fire safety, acoustic control, and tactile comfort are essential.
Water-based lamination, on the other hand, employs eco-friendly adhesive emulsions that are applied uniformly to one or both substrates before being pressed and cured under controlled temperature and pressure. This technique supports multi-layer constructions, soft-touch finishes, and breathable composites, making it ideal for sofa upholstery, interior furnishings, and decorative panels. Water-based adhesives offer low VOC emissions, improved workplace safety, and compatibility with a wide range of porous and non-porous materials.
Both lamination methods are compatible with the following substrates and foam types:
- Flexible Polyurethane Foam (PU)
- Single Knit
- Nylon Half
- PIP Film
WTEC’s lamination lines are equipped to handle single-sided and double-sided bonding, with support for roll-to-roll, sheet-fed, and custom profile formats. Our process ensures uniform adhesive distribution, minimal material distortion, and compatibility with downstream operations such as die-cutting, slitting, and CNC profiling.
