The Container Sets the Sleeve
Empty trays are the wrong reference for this sleeve. Custom Food Packaging Sleeves need to clear the container after filling, sealing and lidding because those final details determine where the paper grips and whether the printed face stays centred.
A ready-meal tray may have a raised rim, lidding film, snap-on lid or small dimensional variation after filling. A dessert tub can taper towards its base. A bakery tray may flex more than a rigid plastic container. Those details change where the sleeve grips, how easily it slides on and whether the printed front panel stays centred.
This is the main role this packaging should own: adding a printed paperboard outer around an existing food container without pretending the sleeve is the primary structure.
For restaurants and food producers still deciding whether they need a tray, carton, cup or sleeve, custom food packaging for restaurants and takeaways starts with the food, heat, grease and handling journey rather than artwork.
