Peelable heat sealing foil; suitable for low temperature storage, high temperature uses and PCR

Heat sealing offers a 100% effective method of plate sealing, for complete seal integrity, as well as being quick and cost effective.

Our Peel Heat Seal is a laminate seal compatible with polypropylene plates. It can be removed from polypropylene plates by peeling, even with a plate which has been removed directly from -80 °C storage.

Peel Heat Seal forms a complete seal to a plate enabling very low temperature uses, including very low temperature storage, and high temperature uses, such as PCR (when used with a pressurised heated lid).

The seal demonstrates moderate solvent resistance and can be utilised for short term compound storage at room temperature.

Peel Heat Seal is available as sheets, for use with manual and semi-automated sealers, such as our 4s3™ Semi-Automatic Sheet Heat Sealer, and in multiple roll formats compatible with specified automated heat sealers, such as our a4S Automatic Roll Heat Sealer.
