Solvent resistant heat sealing foil, peelable; suitable for low and room temperature compound storage

Principle

The DMSO Resistant Peel Heat Seal is a foil seal compatible with polypropylene and forming an excellent seal to cyclic olefin copolymer (COC) plates.

The solvent resistance of this seal enables its use for low and room temperature compound storage in Dimethyl Sulfoxide (DMSO) and organic solvents. 100% DMSO can be stored at room temperature for 12 months without deterioration of the seal.

It forms a weld seal to polyethylene plates and cannot be peeled off. Access is by piercing using a blade, needle, or a 4titude® Pierce Plate (4ti-0398). It can be removed from polypropylene and COC plates by peeling and can be peeled directly from a plate immediately after removal from a freezer.

This seal is available as sheets, for use with manual and semi-automated sealers, such as 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. The sheet seals are inter-leaved with paper sheets to help denote which side is the sealing side and to aid removal of one sheet at a time from the pack.
