Perfotec laser drilling system
PERFOTEC ‘s laser punching system extends the freshness and shelf life of fruits and vegetables, optimizing the permeability of the packaging – a critical element for their quality and shelf life.
Permeability can be controlled by micro-drilling with a laser system that achieves precise quantity and size of holes, a key feature for active modified atmosphere packaging.
It is the only laser in the world that has a patented built-in camera that inspects each hole to be able to ensure the accuracy of the oxygen permeability rate (OTR) of each package.
It can be automatically adjusted “on the fly” to compensate for any variation in film thickness.
Holes are analysed for diameter and shape and if there is inconsistency, the packaging machine can be stopped automatically.
In this way the system guarantees that all packs have the same exact required number and size of holes.
Reliable in all conditions it is specifically designed for vertical or horizontal packaging machines and container sealers and works in damp, cold and dusty environments.
It can make very small diameter holes up to 55 – 60 microns and thus micro-piercings have the highest consistency.
This is particularly important for salads because of the low breathability of these products.
Liner Bags of Perfotec
PERFOTEC ‘s liner bags made of material of organic origin, combined with laser perforation, are special type of bags for transport and storage of fresh fruits and vegetables.
They offer prolonged freshness and a longer shelf life, while weight loss is almost zero.
With an ideal water vapour transmission rate (WVTR) that prevents condensation and droplet formation, it allows extra moisture to escape from the bag minimising the growth of fungi and bacteria in the product.
With balanced CO2 permeability which can prevent damage to tissues discoloration and odor.
In this way it is possible to achieve low oxygen levels just enough to keep the product “asleep” while preventing excessive CO2 build-up.
By maintaining optimal MAP conditions and avoiding an anaerobic environment, a longer shelf life is achieved
It can be printable, plasticizer-free, GMO-free, certified compostable material.
NOVEL PACK is active in Greece and Cyprus as an authorized agent of PERFOTEC, SEALED AIR® for CRYOVAC® brand food packaging solutions, offering recyclable materials and packaging machinery.
