The advantages of the polyethylene film are 

• The material can be seen through the film.
• It can be sealed accordingly to the material's size.
• The sterile material can be stored for a long time.
• Cost effectiveness in relation with other packaging systems.

Biolene´spolyethylene packaging system has printed, all along the roll, a chemical indicator for ethylene oxide.  It turns from yellow to blue when it is exposed to the gas.  It also has advantage of expediting the operator´s tasks, reducing the time employed un packing the material to be sterilized.

They come in rolls in a range from 04 to 50 cm width in 70 microns thick.
