Frequently Asked Questions about Pressure Sensitive Adhesives (PSA)
Why can PSAs stain paper labels?
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.
How to prevent degradation of PSA?
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.
How can we reduce waste from labels?
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.
How are Hot Melt Pressure Sensitive Adhesive (PSA) applied?
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.
