The resistant and transparent copolymer based plastic coating bonds firmly with the glass surface and performs the following functions:

Protects the glass surface against mechanical damage (Scratch protection)

Holds the fragments together in the event of the glass breaking (Splinter protection)

Minimises liquid loss in the event of the glass breaking (Protection against contents escaping and spraying)

Absorbs UV rays upto a light wavelength of 380 nm (Light protection)

Do not expose Protect bottles to open flames or direct heat, e.g. on a laboratory hot plate. The maximum operating temperature is 135°C. Bottle should not be exposed to this temperature for more than 30 minutes.

Protect bottles are suitable for freezing (-30°C)and it can also be used in microwaves. However, the plastic coating does not increase the permissible pressure at which they can be used.
