This type of reclosure will better seal in the moisture after the package is opened, as it closes on a much larger surface area than an overcap, therefore keeping its contents fresh. The design is suitable for modified atmosphere packaging and high-speed tray sealing applications. The package design optimizes marketability: allows for unique package shapes; hangs on a peg; stands in a well; lies on its side; stackable; rugged to withstand transport. These results make the package suitable for sliced meat or cheese products.
