PR1MA™ Extra Stretch Sealing Film

Flexible, airtight laboratory seal.

PR1MA™ Extra Stretch Sealing Film is a colorless paraffin/polyolefin film that molds to almost any surface, creating a secure seal for a wide range of laboratory containers. It adheres to test tubes, centrifuge tubes, petri dishes, flasks, bottles, and beakers, making it an essential tool for protecting sensitive samples.

This latex-free sealing film provides a strong yet flexible moisture barrier while allowing controlled exchange of H2O vapor, O2, and CO2, ensuring sample integrity without compromising off-gassing. Its unique formulation makes it stretchable, moldable, and self-sealing, sticking to itself or nearly any material. Ideal for use at low temperatures (including LN2 applications) and at higher temperatures, it forms an extraordinarily liquid-tight, airtight seal for dishes, tubes, glassware, and plasticware.

Whether you're preserving sensitive biological samples or securing vessels for transport or storage, PR1MA™ Stretch is the go-to sealing solution trusted by scientists across research, pharmaceutical, academic, and industrial laboratories.

Main Attributes

• Multi-surface adaptability – Seals securely to glass, plastic, and metal surfaces
• High stretchability – Stretches up to 350% for a snug, custom fit
• Self-sealing – Sticks to itself and forms a tight wrap around irregular surfaces
• Liquid-tight barrier – Ideal as an overwrap for caps, lids, and stoppers
• Flexible and translucent – Allows for easy visual inspection of contents
• RNase & DNase free – Safe for molecular biology applications
• Latex-free – Suitable for sensitive lab environments
• Cold and heat resistant – Maintains performance in a wide range of temperatures

PR1MA™ Extra Stretch Sealing Film also comes in sterile sheets.

When sterility matters, choose PR1MA™ Extra Stretch Sealing Film Sterile Sheets. Pre-cut in 2 x 4 In. and 4 x 4 In. sheets, these sterile seals are perfect for petri dishes, flasks, plates, and other containers. Packaged in resealable bags of 100 ready-to-use sheets, they eliminate the need for measuring or cutting.
