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
