Improve CO2 Footprint
Convenient and Light Weighting Packaging with No
Compromise on Performance
The industry has been already done some
progress on the packaging area, but how to
go even further into the consumer needs
considering the current challenges of the
industry?
• HOW TO INCREASE
RECYCLABE CONTENT EVEN
MORE?
• HOW TO DOWNGAUGE
PLASTIC CONTENT AND
KEEP OR EVEN IMPROVE
BARRIER PROPERTIES AND
TOP LOAD?
• HOW TO REACH ABOVE
MENTIONED TARGETS AND
STILL GET FOOD CONTACT
CLEARANCE?
• HOW TO EMIT LESS CO2 IN
THE VALUE CHAIN?

BUDIT® L24
Heat Management of Thermoplastics with Enhanced IR Absorption
BUDIT® L24 is a very efficient, wavelength-absorbing ingredient that is easily dispersible in all
polymers.
Applications
Heat management of thermoplastics (PP, PE,
PET, PC) during energy-assisted forming
processes such as thermoforming

Energy efficiency
Heat Management of Thermoplastics with
Enhanced IR Absorption
BUDIT® L24 is suitable for NIR light and converts the infrared light energy into
thermal energy, resulting in rapid and homogeneous heating in the polymer.
Convenient to dose, the masterbatch allows for an easy dispersion and processing
in a broad variety of polymers.
Benefits
 Energy savings of up to 20 %
 CO2 footprint reduction
 Enables faster cycle times
 Large processing windows, especially for transparent materials
 Reduced rejects
 Homogeneous heat distribution due to controlled IR absorption offering high
quality geometries
 Free from antimony, bismuth and tin making it safe for food and medical
applications

based on the temperature readings of preform 1 and 2
**: As the preforms deformed too much and the machine stopped, preform no 4 could not be removed and hence not be
