Overview of how glue and other adhesives work.
Pressure-sensitive adhesives (PSAs) used in tapes and films are formulated from a variety of polymers, including natural and synthetic rubbers, thermoplastic elastomers, polyacrylates, polyvinylalkyl ethers, and silicones.1
These adhesive materials are typically prepared in solvent-based, hot-melt, or water-based formulations and are applied as coatings onto various substrates, such as:
- Paper
- Cellophane
- Plastic film
- Fabric
- Metal foil1
Unlike contact cements, these adhesives are specifically designed to bond surfaces when mated under brief pressure at room temperature. Due to environmental regulations, the industry is increasingly shifting away from solvent-based formulations in favor of water-based alternatives.1
