Premium double-sided adhesive chemical sheet (0.6 mm – 2.0 mm) for toe puffs & heel counters. Dual hot-melt coating, high rigidity, SATRA compliant. Free samples!
A double-sided adhesive chemical sheet (commonly known as dual-glue chemical puff board) is a solvent-dip or hot-melt impregnated nonwoven substrate coated on both sides with a heat-activated adhesive resin. Specially engineered for footwear manufacturing, leather crafting, and luggage structural reinforcement, this material acts as an internal stiffener for toe puffs and heel counters. The dual-sided adhesive coating creates an instant, strong bond between the outer leather/synthetic upper and the inner shoe lining simultaneously when heat-pressed, eliminating the need for manual liquid glue application during assembly. Solamni supplies this material in standard flat sheets (0.90 m × 1.50 m or 1.00 m × 1.50 m) or continuous rolls with strict thickness options (0.60 mm – 2.00 mm).

Utilizing double-sided adhesive chemical sheets streamlines shoe lasting operations by combining structural stiffening and multi-layer bonding into a single thermal press step:
Application Process Flow:
- Die‑Cut Preform Chemical Sheet
- Heat Activation Press (90°C – 130°C)
- Positioning Between Upper & Lining
- Pneumatic Toe / Heel Lasting Machine
- Cooling Lock‑In & Double‑Sided Bond
- Permanently Molded Shoe Counter
- Precision Die-Cutting & Skiving: The chemical sheet is cut to the specific toe or counter pattern, with edges skived thin for smooth transitions.
- Thermal Activation: The preform is briefly heated to soften the core and melt the double-sided adhesive film.
- Simultaneous Lamination: Placed inside the shoe assembly, a pneumatic lasting press clamps the piece. The adhesive instantly bonds to both the underside of the upper and the face of the lining, forming a rigid, seamless composite structure upon cooling.
Industrial Application Scenarios
Solamni double-sided adhesive chemical sheets are specified across diverse footwear and leather goods manufacturing sectors:
Formal & Work Footwear
Heavy‑gauge (1.2 mm – 2.0 mm) heel counters and toe puffs for dress shoes, leather boots, and military footwear requiring firm shape support.
Casual & Lifestyle Sneakers
Medium‑gauge (0.8 mm – 1.2 mm) toe puff inserts that keep upper shapes crisp while enduring daily wear.
Handbags & Leather Goods
Thin‑gauge (0.6 mm – 0.8 mm) structural interlinings for bag flaps, wallet interiors, and belt straps to add body without adding excessive weight.
F A Q
Q1: What is the advantage of double-sided adhesive coating over single-sided coating?
A1: Single-sided sheets require manual glue brushing on the uncoated side to secure the lining. Double-sided adhesive sheets activate both sides at once under heat, halving assembly steps, eliminating hazardous solvent exposure for workers, and preventing glue spots or uneven lumps on the lining.
Q2: Can this material be skived smoothly at the edges?
A2: Yes. The chemical impregnation provides uniform density across the sheet, allowing high-speed skiving machines to feather the perimeter edges down to 0.1 mm without shredding or tearing the fibers.
Q3: What is the lead time for standard stock and sample requests?
A3: We maintain warehouse inventory of standard white and yellow-tinted sheets (0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm) for immediate dispatch. Custom thicknesses, roll conversions, or specialized adhesive melting points carry an MOQ of 500 sheets, with physical sample swatches shipped within 3 to 5 business days. Technical specialist Jason Lee provides engineering quotes within 12 hours.
