Parafilm sealing film is an essential laboratory consumable used for sealing and protecting vessels, flasks, test tubes, petri dishes, and other containers. Supplied by LabChoice Australia, this flexible, stretchable thermoplastic film provides an airtight and moisture-resistant barrier that helps prevent contamination and evaporation during storage or incubation.
Manufactured from a unique blend of polyolefins and paraffin wax, Parafilm easily conforms to irregular shapes and adheres smoothly to glass, plastic, and metal surfaces without leaving residue. It is non-toxic, odourless, and semi-transparent—allowing quick inspection of sealed samples. The film can be stretched up to 200% of its original length, ensuring a secure and reliable seal even under varying laboratory conditions.
Compliant with ASTM D882 (tensile properties of thin plastic sheeting) and ISO 4593 (film thickness standards), Parafilm sealing film meets international laboratory performance requirements. Trusted by Australian schools, research institutions, and industrial labs, LabChoice Australia’s Parafilm sealing film ensures sample integrity, durability, and convenience for daily laboratory applications.
Each roll of Parafilm sealing film supplied by LabChoice Australia undergoes ISO 9001 aligned quality control procedures. This includes inspection for uniform thickness, elasticity, tear resistance and consistent surface finish. Rolls are checked for smooth unwinding, clarity and reliable performance during stretching and sealing. These measures ensure that laboratories receive a dependable sealing medium for daily operations requiring moisture control and contamination prevention.
