Abstract








The multidisciplinary Packer 2020 project
aims at improving packaging of local and organic food by the means of
material development and indicator solutions. The project covers
investigations on the current status and future trends in organic and local
food packaging, development of a new converting unit for forming paperboard
based packages, and creation of novel packaging materials and indicator
solutions.


18 actors from four local and organic food
chains (fish, meat, berries, and mushrooms) in Southern Finland were
interviewed. An ideal local and organic food package is made of renewable
materials and it has ecological characteristics, such as recyclability or
compostability. It should better differentiate the product from conventional
products, and promote the brand.


By utilizing a servo-electric system, the
force production of converting equipment was found to be more adjustable,
accurate and cost efficient compared to hydraulic force production. The
servo-electric approach can thereby be recommended for applications with high
accuracy and force requirements.


Novel breathable dispersion barrier coatings
with a high bio-based polymer content were developed. The print quality on
these coatings was good in varying environmental conditions. The results
indicate that these novel solutions could be viable options to be used in
packaging of a variety of food products.
Copper acetate and copper sulfide based sensing films were developed
for the electrical and optical detection of hydrogen sulfide (H2S) and total
volatile basic-nitrogen (TVB-N), respectively. Indicators were produced by
inkjet printing on polyethylene terephthalate and paper substrates. The
sensors have shown over six orders of magnitude change in resistance when
exposed to low concentrations of hydrogen sulfide, ammonia and dimethyl
amine, while the indicators were also found to have a significant change in
color when exposed to these analytes. Due to large change in resistance of
these sensors they can be integrated in a low cost wirelessly readable
RCL-circuit.
