Laser Perforation and Scoring
Laser scoring for easy open
Perftech has invested in the newest laser perforation technology to offer our clients the most cutting-edge and cost-effective solutions. In 2019 we installed a state-of-the-art, highly versatile and powerful laser perforator. It allows us to perforate or score material in any direction with total precision. With our custom CAD software we can get you into market faster without the need for tooling or fabrication.
Common applications for laser perforation include:
- Fresh-cut produce in bags or trays with lidding: Customized perforation patterns help produce optimal headspace for shelf-life extension of perishable fruits and vegetables. This keeps the packaged produce fresher for longer by delaying the ripening process and reducing ethylene production.
- Steam release for microwave-ready packaging: Customized patterns ensure quick and uniform microwave cooking of frozen vegetables and ready-to-eat meals. The perforations allow controlled release of the steam for a perfect cooking result.
- High-altitude burst elimination: Perforation lets the headspace in sealed packages match the changing atmospheric pressure at altitude without compromising shelf life. A single micron perforation, invisible to the eye, can allow the headspace inside the package to equalize to the surrounding atmospheric pressure to maintain seal integrity.
- Venting of excess air in bulk packaging: High-speed filling and case-packing lines cannot slow down for filled bags with excess air to dissipate. Perforation enables rapid deflation time. Adding perforation can allow the package to delate rapidly, optimizing case packing.
Laser perforation can be continuous or in register with the print pattern. It is a non-contact method so quick setup and changeover allows for customization of patterns to your specific application. Laser perforation allows for highly accurate control of hole size, shape and location. It makes Perftech’s laser perforation the ideal technology for applications requiring a precise but relatively low level of porosity.
Laser scoring for easy open and peel/reseal
Give your customers extra value with an even more user-friendly package. Scoring makes opening pouches easy with each use. Scoring can be done in the web direction, cross web, and even as a contoured score to optimize openings around seals and zippers to match your pouching needs.
Laser scoring requires no tooling. Because of its greater flexibility and lower up-front cost, it is a viable alternative to traditional rotary die cutting for peel/reseal applications.
