Flame lamination is the process of laminating flexible materials with an open flame. This technique is used to seal materials such as fabrics to foams (often polyurethane foams), and/or other lofted non-woven polyesters.
First the base material is exposed to the flame to create an adhesive surface with heat, then the second material is introduced to the surface to secure the bond. This cuts costs in that the heated material turns “tacky” to create a natural (chemical-free) adhesive.
In addition, the use of flame lamination in soft goods manufacturing is an environmentally friendly alternative and much faster means to laminate parts than most other methods. Flame lamination is ideal for sealing foam-filled cases with custom compartments or for products that come into contact with the skin.
