Abstract
The current trend in packaging materials heads towards
green chemistry using sustainable and renewable
materials. A number of novel packaging coatings have been
recently developed on paper, paperboard or bio-based
plastic films in order to produce special and enhanced
product properties as well as to improve the
competitiveness of traditional industries such as forest
and plastic. Especially new type of thin coating
technologies such as atomic-layer-deposition (ALD) and
sol-gel hybrid coatings have been tested by VTT for
packaging purposes. The thin coatings have been applied,
for example, on polylactic acid (PLA) films and coated
paper and paperboard to improve the moisture, gas and
grease barrier performance. In addition to new coating
technologies VTT has recently developed coating processes
for lab- and pilot-scale roll-to-roll processes. Thin
hybrid coatings as well as many types of biopolymer based
coatings and free-standing films have been produced.
Coatings can be applied by flexo, soft bar, foam, curtain
and spray coating methods, including optional
pre-treatment by plasma or corona as well and
post-treatment/curing by cold or hot air drying,
IR-drying or UV-curing.
