Frequently Asked Questions about Pressure Sensitive Adhesives (PSA)
PSA stands for Pressure-Sensitive Adhesive, a type of adhesive that forms a bond when pressure is applied, without needing heat, water, or solvents. It's commonly used in tapes, labels, stickers, and glue dots1. The strength of the bond depends on the amount of pressure applied and the surface characteristics.
PSAs are designed to work at room temperature but can lose tackiness in extreme temperatures. They are different from structural adhesives, which require curing processes like evaporation or chemical reactions1.
PSAs are formulated with plasticizers, which enable a workable viscosity for coating and help maximize wet out for bonding. Plasticizers are oils so over time, they can bleed into paper and cause a stained appearance. Bostik has patented PSA technology that can provide stain resistance on paper face stocks.
PSAs will degrade with extended time at elevated temperatures when the line is not running. Degradation can negatively affect the appearance, processability, and performance of an PSA. To prevent producing PSA labels or tapes out of specification, it's important to control the temperature of the melt tank, hose, and coating head during equipment-related downtime.
Linerless labels allow you to reduce waste. They are similar to tapes in that silicone is coated on the surface of face stock, eliminating the need for a separate release liner. Along with reducing waste, linerless labels offer operational and inventory efficiencies. Linerless labels with Bostik hot melt adhesives can be used in e-commerce, grocery weigh scale, and quick service restaurant applications.
- Adhesion Mechanism – PSAs remain tacky at room temperature and bond instantly when pressed onto a surface.
- Viscoelastic Properties – They balance flow and resistance, allowing them to conform to surfaces while maintaining strength.
- Molecular Interactions – Van der Waals forces contribute to bond strength, ensuring durability.
- Temperature Sensitivity – PSAs may lose tack at low temperatures or reduce shear strength at high temperatures.
Pressure-Sensitive Adhesive (PSA)
- Sticks with light pressure: No need for heat, water, or solvents—just press it on.
- Tacky to the touch: Always slightly sticky, allowing for repositioning (in some cases).
- Removable or permanent: Available in both kinds depending on application.
- Common uses: Packaging tape, stickers, medical bandages.
Pressure-sensitive adhesives (PSAs) are fascinating little marvels of chemistry! They’re made from a blend of materials that give them their signature stickiness without needing heat, water, or solvents.
Slot die is the most common type of coating method used with PSAs. Typically hot melts are transfer coated from the release liner to the face stock to achieve the smoothest surface on the adhesive for bonding. Roll coating or gravure printing may be used to pattern coat hot melts.
