Modified atmosphere packaging

Modified atmosphere packaging of vegetables

Laser perforation of plastic packaging films can increase the shelf life of certain fruits and vegetables, compared with unperforated packaging. So-called modified atmosphere packaging (MAP) technology uses laser-perforated holes to regulate the levels of oxygen, carbon dioxide, nitrogen and other gases inside the pack, maintaining the freshness of the produce inside.

Our CO2 lasers are used to perforate holes at regular intervals across the plastic packaging film. The optimum conditions vary according to product type, so the hole size and spacing must be precisely controlled. The laser process is flexible – hole size can be monitored and adjusted on the fly, and hole spacing can be changed very easily.
