Easy Ventilation – micro-air-holes
enhance shelf-life of food
In perishable foods packaging, quality and shelf
life depend on a balance between air circulation
and preservation of humidity. For adequate perforation
of the packaging, ROFIN lasers offer significant
advantages over conventional processes,
such as needles or flame: Based on 25 years of
experience in laser perforation, ROFIN uses CO2
lasers with high pulse intensities to perforate all
layers of the packaging material. The micromelted
edge of each hole prevents microfissures that could
damage the packaging integrity.
Perforation is also suitable for pressure exchange
function, like in packages for microwave meals.
With strong packaging materials such as PE/PE
combinations, Laser Perforation can even create
perforation lines with 5 to 50 holes/cm for easytear-
off applications.
