Perforation Solutions for Food Packaging
Safe Quality Food (SQF Institute) Certification
Perftech maintains Safe Quality Food (SQF) certification for the manufacture of food packaging. Our SQF-certified quality and food safety management system supports the rigorous standards required by customers throughout the food packaging supply chain.
Food Packaging Perforation Applications
Fresh-cut produce
Fresh produce continues to respire after packaging, making controlled gas exchange critical to product quality and shelf life. Standard barrier films may not provide the oxygen and carbon dioxide transmission rates required for a specific fruit or vegetable.
Perftech can help determine the required Oxygen Transmission Rate (OTR) for the packaged produce and engineer a precision microperforation pattern to achieve the target permeability. When customers already have established OTR requirements, we can design the perforation pattern to meet those specifications. Our experience with modified atmosphere packaging (MAP) helps customers maintain the appropriate package atmosphere and extend product shelf life.
Microwave Steam-Vent Packaging
Microwave steam-vent packaging allows frozen vegetables and ready-to-eat meals to cook in the package while controlling pressure during heating. Perftech selects and tests the perforation pattern to allow the package to build the pressure needed for effective steam cooking while providing sufficient venting to prevent excessive pressure buildup. Using laser perforation, vents can be placed in specific zones or registered to the printed package so each perforation is positioned consistently on every package across the web.
Meat pads
Absorbent meat and poultry pads use perforated film to encase the absorbent material placed beneath the product in the tray. Perftech’s needle perforation creates controlled openings that allow fluids to pass through the film into the absorbent core while helping retain the absorbed liquid within the pad. Hole size and perforation pattern can be customized for different pad constructions, absorbency requirements and applications.
Package Venting & Pressure Equalization
Sealed flexible packages can experience pressure changes caused by product off-gassing, temperature changes or changes in altitude during transportation. Perftech can engineer perforation patterns that allow packages to vent or equalize pressure while maintaining the required package performance. This can help prevent package swelling, bloating, distortion or bursting during storage and distribution, including products shipped through significant elevation changes.

*Modified Atmosphere Packaging (MAP) is the enclosure of food in a package where the atmosphere inside the package is modified to provide an optimum atmosphere for increased shelf life and food quality. MAP is applied in the food industry to extend shelf life and preserve freshness, flavor and safety of fresh and fresh-cut perishable foods. It also prevents discoloring, ensuring an aesthetically pleasing shelf appeal.
