PR1MA™ Stretch Multi-Purpose Laboratory Sealing Film

Exceptional Flexibility. Superior Seal. Trusted in Labs Worldwide.

PR1MA™ Stretch Multi-Purpose Laboratory Sealing Film is a premium, transparent plastic/paraffin film designed to provide a reliable and adaptable seal for a wide variety of laboratory applications. Engineered to mold to virtually any surface, it delivers secure coverage for laboratory containers such as test tubes, centrifuge tubes, petri dishes, flasks, beakers, and bottles.

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.

Key Benefits & Features

• 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

Advanced Formulation for Sample Integrity

PR1MA™ Stretch is composed of a proprietary blend of paraffin and polyolefins, engineered to provide a flexible moisture barrier that protects delicate samples from contamination and evaporation. While delivering an airtight seal, it still permits the exchange of essential gases like oxygen (O), carbon dioxide (CO), and water vapor (HO)—ideal for cell culture and biological sample storage.
