Key Benefits of PHYLLOMAT® in Low Density Polyethylene Agricultural Film

2014-04-22 3

Major Benefits:

• Better IR-absorption – lower thermicity of the LDPE film –

less loss of heat through the film (i.e. less drop in

temperature at night)

•Improved optical properties for higher transmission of

visible light

• Good UV stability

• Enhanced barrier effects

• Odorless

• No health and safety concerns
