HyperStretch™ is a colorless plastic / paraffin film that molds to almost any surface. It seals and adheres to an endless list of lab vessels and containers including test tubes, centrifuge tubes, petri dishes, flasks, bottles and beakers. HyperStretch™ Sealing Film is an invaluable laboratory tool.

A proprietary formula of paraffin / polyolefins, HyperStretch™ Sealing Film is latex-free and provides a strong but flexible moisture barrier that protects sensitive samples while allowing exchange of H2O vapor, O2 and CO2. This seal allows off-gassing without sacrificing integrity.

HyperStretch™ is moldable, stretchable and sticks to itself or almost any material. It can be used at low temperatures including LN2 applications and at higher temperatures on dishes, tubes, glassware, plasticware and as an overwrap for lids, caps and stoppers to form an extraordinarily liquid-tight, airtight seal.
