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.

DuraSeal™ Sealing Film

• Durable, heat-resistant, solvent-proof laboratory sealing film
• Chemically resistant
• Heat resistant & Microwave compatible
• Tight sealing
• Tear resistant

DuraSeal™ is easy to use. There is no inter-leaf paper to strip away, just stretch the film symmetrically over a container opening and the 1.5 mil thick film contracts inwardly around the opening or neck of the container to provide a drum-tight, water-proof seal. The film can be elongated 500-800% before breakage. The film clings to itself, especially after stretching so the free edges of the film may be stretched around the container to secure the container edges.

Permeability Information

• Oxygen = 125cc/100in2/24hrs at 23°C
• Carbon Dioxide = 1300cc/100in2/24hrs at 23°C
• Water Vapor = 1.0g/100in2/24hrs at 38°C and 90% R.H.

Parafilm® M Sealing Film

Flexible, stretchable lab film for moisture-resistant sealing.

Parafilm® M Sealing Film is a trusted solution for sealing and protecting labware, widely used in scientific, medical, and industrial settings. This semi-transparent, thermoplastic film is made from a blend of polyolefins and waxes, offering two-way stretch and excellent sealing capabilities on various surfaces, including test tubes, flasks, beakers, and petri dishes.

With the ability to stretch over 200% of its original size, Parafilm® M conforms tightly to irregular surfaces and forms a strong, moisture-resistant barrier that prevents evaporation and contamination.
