Case Study

Vertical Seal Tray/Dolav Liners

• Manufactured with a vertical seal rather than the traditional standard bottom seal.
• Reduction in product entrapment as now the base of the tray/dolav liner is flat with no bottom seal when decanting.
• Leakages can be an issue with some processors of raw meat.  As the vertical seals are now on the side of the liner, this will eliminate any blood/fluid loss at the base of the liner.
• The custom fit fills all four corners of the tray/dolav and will use less polythene than the alternative side gusset versions.
• A competitor was supplying this processor with M&S G4 at 35 micron.  Hanmere G4 accreditation at 30 microns reduces costs and further plastic waste.
