Function and introduction:
The sealing film is a semi-transparent, flexible film composed of a blend of waxes and polyolefins.  It is a ductile, malleable, non-toxic, edible, tasteless, odorless, and self-sealing thermoplastic.  Its thickness is 125um.
1,It is waterproof and moisture-proof, which can effectively prevent the volatilization and contamination of experimental samples.

2,The sealing film can effectively protect anhydrous substances.
3,Single-layer sealing, oxygen-permeable and air-impermeable; multi-layer sealing, oxygen and air impermeable.
4,Glue-free and super malleable, it can be tightly wrapped on the surface of test tubes, flasks, and various irregular tools and objects.
5,Contains no organofluoride, more environmentally friendly, stable process, high elasticity, easy to use, and good wettability

Performance data:
Permeability: Oxygen - 150cc/m2/24 hours at 73 F and 50%RH.
Oxide: 400CC/m2/24 hours at 73F and 50%RH.

Ductility: 3 to 5 times ductility. After stretching, it can self-sealed around the mouth of the container .
Deep freezing resistance: resistant to -80°C low temperature, short-term resistance to gas phase liquid nitrogen, no change for 15 days
Normal temperature: When the temperature exceeds 35 degrees, the performance of the film begins to decrease and it becomes difficult to unfold.
