Laser Micro-Perforating
Laser micro-perforating is a process of generating a series of small through holes for modified atmosphere packaging. Perforations can also be used to help achieve controlled airflow and moisture release in various packaging products such as extending shelf life for fresh produce and burst protection for changing air pressure. Perforations also offer the capability of easier filling – air scapes quickly during filling while the product remains contained. Packages are also more compressed for improved stacking.
Tailored to your project.
AcuBreathe is Preco's laser micro-perforating solution for easy-breathe, easy-pack and easy-fill packaging. From gas transmission to moisture release, AcuBreathe technology can be tailored to fit a range of material types and thicknesses.
