Openair® plasma for thermoformed film for food – better bonding of printing inks at high processing speeds
High
quality printed images are a necessity, especially on food packaging.
Ink can’t bleed into the product, however, and
that ink must bond securely to the packaging. Printed cups, such as
for yoghurt or margarine, must be stacked together for transport
before they are filled but ink transfers from one printed exterior to
the interior of the next cup must be avoided at all cost.
Plasma pretreatment of thermoformed film secures reliable ink bondingPretreatment
with Openair® plasma can safely prevent this undesired effect.
Thanks to plasma activation, bonding of printing inks to the food
packaging is substantially improved. Inks will not rub off. The speed
of subsequent flat or rotary screen printing can also be
significantly increased.
