Hotmelt Web Bonding and Adhesive Film Lamination
topic
Hotmelt adhesive web lamination uses thin nonwoven adhesive webs of polyamide, polyester, or EVA copolymer at 5 to 30 grams per square metre as dry bonding interlayers positioned between substrate layers before combined heating in a fusing press or calender at 130 to 180 degrees Celsius, providing controlled adhesive distribution without liquid application for apparel interlining lamination, shoe component bonding, and filter cartridge construction.
Role
Provides precise, uniform adhesive distribution for bonding applications requiring consistent open area breathability or defined bond coverage patterns through dry adhesive web application that eliminates the non-uniformity risks of liquid adhesive coating, with hotmelt web lamination being the standard bonding method for apparel interlining where the defined web weight and uniform coverage provide reproducible bond strength and handle characteristics required for garment construction quality.
