Question 1

What makes AHMPSA-40 superior to rubber-based hot-melt PSAs for outdoor label applications?

Accepted Answer

AHMPSA-40's acrylic backbone provides inherent UV and oxidative stability without added stabiliser packages, resisting yellowing and embrittlement after prolonged outdoor exposure. Rubber-based hot-melts degrade above 60°C and require separate UV stabilisers, whereas AHMPSA-40 maintains full peel and tack performance up to 80°C continuous service temperature.

Question 2

What coat weight and substrate types are recommended for label stock converting?

Accepted Answer

For standard face stocks (BOPP, PET, paper), a coat weight of 18–25 g/m² applied at 130–140°C via slot-die or roll coater delivers >8 N/25mm peel on stainless steel. For low-energy polyolefin surfaces such as PE or PP containers, corona treatment and coat weights of 25–30 g/m² are advised to achieve adequate initial tack and final adhesion.

Question 3

How does AHMPSA-40 perform in cold-chain and refrigerated packaging environments?

Accepted Answer

AHMPSA-40 retains sufficient tack and adhesion down to -20°C, making it suitable for cold-chain labels applied at ambient temperature to chilled or frozen substrates. Release force on silicone-coated liners is 8–20 cN/25mm depending on liner type, and dispensing performance on high-speed label applicators remains stable across the full service temperature range.
