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.

Laser perforation

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.
