Film becomes soft and sticky at about 130° to 150°F (54° to 66°C).

The tight moisture-proof layer has a strong seal, even if there is exhaust gas will not be released from the glassware.
Use odorless, colorless and translucent coverings to reduce the risk of data tampering.
Prevent moisture and volume loss due to material composition and tight seal.
Flexible and self sealing materials allow it to adhere to irregular shapes and surfaces.
The stretch exceeds 200% of the original length.
It can resist a variety of polar substances (such as salt solution, inorganic acid and alkaline solution) for 48 hours.
