Point Bonding and Emboss Lamination
topic
Point bond lamination uses engraved roll patterns on thermal calender machines to create discrete bond points between substrate layers at pattern coverage of 10 to 30 percent of laminate area, with the raised calender pattern surface concentrating heat and pressure at contact points that melt through the upper substrate to bond the layers, while inter-point areas remain unbonded and flexible providing the balance between bond strength and composite drape for apparel and hygiene applications.
Role
Produces composite laminates with the flexibility and drape of unbonded fabric in the inter-point areas combined with the structural integrity of thermal bonds at contact points, enabling production of soft composite materials for hygiene products, medical laminates, and apparel interlinings where full-area calender bonding would create unacceptably stiff composites but the structural integrity of the laminate requires defined bond area that partial bonding provides.
