High tensile strength, suitable for bead mill applications, peelable

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

Our Clear Seal Plus is a clear polymer film forming a peelable seal to polypropylene, polystyrene and cyclic olefin copolymer (COC) plates.

The excellent tensile strength of this seal enables its use for sealing of microplates during homogenisation or disruption of seeds or other material such as bead mill applications. Clear Seal Plus forms a complete seal to a plate also enabling short term sample storage.

The Clear Seal Plus is thicker than our standard Clear Seal for application requiring high tensile strength, but is not as suitable for optical applications due to decreased transmission through the thicker sealing layers. For optical applications please refer to our Clear Seal.

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