Excellent Adhesion on Various Substrates – Bonds to nonwoven, polyethylene film, tissue, and paper.
Clean Application – Low stringing and no residue during high-speed production.
Stable Performance – Maintains adhesion in varying temperature and humidity conditions.
Odor-Free & Skin-Safe – Non-toxic and suitable for hygiene product applications.
Classification
IWG offers several PSA adhesive types for different production needs:
Hot Melt PSA – For fast, clean application in hygiene and packaging lines.
Water-Based PSA – Eco-friendly option for paper and tissue lamination.
Specialty PSA Grades – Designed for soft touch, removable, or low-temperature bonding.
Applications
Baby Diapers
Used for bonding nonwoven layers, elastic components, and positioning tapes. Offers stable tack, excellent peel strength, and low odor — ensuring safety and comfort for infants.
Mattress Manufacturing
Provides flexible adhesion between foam and fabric layers. Maintains softness, elasticity, and long-term durability without discoloration or odor.
Paper Bag Packaging
Ideal for sealing and lamination of paper handles and side seams. Delivers quick tack, clean bonding, and excellent aging resistance for retail or food packaging.
FAQs
Q1: What is the difference between PSA and hot melt adhesives?
PSA adhesives bond instantly under pressure and remain permanently tacky, while hot melt adhesives require melting and solidification. PSAs are preferred for nonwoven and paper applications that need flexibility and re-stick properties.
Q2: Are PSA adhesives safe for hygiene and skin-contact products?
Yes. IWG’s PSA adhesives are odor-free, non-toxic, and dermatologically tested, making them suitable for baby diapers and hygiene product manufacturing.
Q3: How can I optimize PSA adhesive performance on high-speed lines?
Maintain consistent coating temperature and pressure, ensure clean substrates, and select a PSA grade that matches your substrate surface energy and coating speed. IWG engineers can recommend ideal viscosity and tack levels for your line.
