Bemis Parafilm® M Roll

Parafilm® M is a highly versatile sealing film made primarily of polyolefins and paraffin waxes. It is designed to provide a tight moisture and vapor barrier, offering reliable protection for research applications, particularly in laboratory settings. Known for its flexibility, self-sealing properties, and high stretchability, Parafilm M clings well to irregular shapes and surfaces without the need for additional adhesives. It is ideal for sealing containers, glassware, and other laboratory items to prevent contamination, moisture loss, and evaporation.

Parafilm M is resistant to many polar substances, such as saline solutions, inorganic acids, and alkaline solutions, for up to 48 hours. Its odorless, colorless, and semi-transparent properties make it particularly useful for applications that require data integrity and contamination control.

Key Features & Benefits

✅ Stretch and Cling Properties

• Stretches up to 200% of its original length, allowing it to conform tightly around irregular shapes and surfaces, providing a secure seal even on non-standard containers.

✅ High Chemical Resistance

• Resistant for up to 48 hours against many polar substances, such as:
  • Saline solutions
  • Inorganic acids (e.g., hydrochloric acid, sulfuric acid)
  • Alkaline solutions
• Ideal for protecting sensitive samples and preventing contamination.

✅ Moisture and Volume Retention

• Prevents moisture loss and volume evaporation during long-term storage or experimentation.

✅ Safe and Non-Toxic

• Odorless, colorless, and semi-transparent—does not interfere with experiments and allows for visual inspection of sealed items.

✅ Temperature Resistance

• Softens and becomes sticky at 130° to 150°F (54° to 66°C), making it ideal for a wide range of applications but not suitable for high-heat environments like autoclaving.

✅ Easy Handling

• Self-sealing without the need for additional adhesives. Just stretch and apply to the surface to form an airtight seal.
• Available in various roll sizes to accommodate different laboratory needs.
