Product Information

For storage and transport, peelable

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

Our Thermal Bond heat seal is a heavy duty laminate foil seal suitable for providing a very strong, but peelable seal. The seal is compatible with polypropylene plates to provide a high degree of sample protection. It demonstrates very good solvent resistance and can be used for very low temperature compound storage, in DMSO and organic solvents, and long term room temperature storage such that it is recommended as suitable for sample transportation.

The seal can be pierced only by using a blade or using the 4titude® Pierce Plate (4ti-0398).

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

A blue stripe on the sheet foils clearly indicates the non-sealing surface, for ease of seal orientation and handling.
