Hot Tack

Hot Tack Testing Equipment

Thwing-Albert is the US distributor for the J&B Hot Tack Tester 5000MB, a dedicated hot tack testing instrument designed and built for automatic measurement of heat seal strength on flexible packaging materials.

What Is Hot Tack Testing?

Hot tack is distinct from final seal strength. Final seal strength — measured after a seal has fully cooled — is covered under our Seal Strength testing category. Hot tack measures the seal at the moment it is first stressed, before cooling. This distinction matters because a seal that performs well in a cold peel test can still fail on a high-speed packaging line if its hot tack strength is insufficient.

Who Needs Hot Tack Testing Equipment?

Hot tack testers are used by producers of raw materials, plastic films, and laminates; extruders; packaging machine manufacturers; food and chemical companies; and R&D and quality control laboratories running SQC/SPC programs on heat-sealable packaging materials.

Industry Standard

Hot tack testing equipment from Thwing-Albert is designed to fulfill the requirements of ASTM F1921 — Standard Test Methods for Hot Seal Strength (Hot Tack) of Thermoplastic Polymers and Blends Comprising the Sealing Surfaces of Flexible Webs.
