parafilm for sale
Parafilm is a versatile laboratory and industrial sealing material that combines flexibility with exceptional barrier properties. This semi-transparent, self-sealing film offers remarkable stretchability, capable of extending to 200% of its original length while maintaining structural integrity. Made from a blend of paraffin wax and polyolefins, parafilm provides an effective moisture-resistant seal that protects contents from contamination and evaporation. The material adheres effectively to irregular surfaces, including glass, plastic, and metal, creating an air-tight seal that's crucial for laboratory sample preservation. Each roll comes in standardized dimensions, typically 4 inches wide by 125 feet long, making it suitable for various applications. The film's unique composition allows it to remain stable across a wide temperature range, from -45°C to 50°C, making it ideal for both refrigerated storage and room temperature applications. Its chemical resistance properties protect against many common laboratory substances, while its transparent nature enables clear visibility of labeled containers beneath the seal.
