Adhesive Coating for Pressure-Sensitive Applications
topic
Pressure-sensitive adhesive coating applies rubber-based, acrylic, or silicone PSA at 15 to 60 grams per square metre onto textile or film substrates using slot die, gravure, or knife coating followed by drying and lamination with release liner, with coat weight uniformity within plus or minus 2 grams per square metre being required for consistent peel adhesion across the full tape or label width, and aged adhesion performance being verified by accelerated ageing tests.
Role
Produces the adhesive-coated textile and film products including medical tapes, wound dressings, and industrial adhesive tapes through the controlled application of PSA compounds that must provide consistent peel and tack performance across the full coated width and throughout the product shelf life, with coat weight uniformity and adhesive formulation selection governing the adhesion performance characteristics that define product suitability for each medical and industrial application.
