UGI Packging specifies food-contact grease-resistant laminated white card for this direct-use application. Ordinary white card can leak oil and does not meet the required food-contact and performance specification for this particular meal-box use.

No. The specification on this page belongs to the stated burger and children meal-box application. The correct board, coating and barrier depend on the food, oil and water exposure, contact conditions, temperature, printing position and complete packaging structure. UGI Packging confirms the material route against the actual brief.

The relevant coated specialty paper is purchased in large rolls. One roll can produce tens of thousands of boxes, so a customer-specific small order cannot usually open a dedicated roll economically. The material purchasing unit is therefore much larger than the requested finished quantity.

Mixed production can be considered only when the specifications genuinely match. Combining different jobs can introduce differences in grammage, coating thickness and colour, so UGI Packging must control the material specification rather than assume that any remaining roll is interchangeable.

A suitable standard blank box may already have a production die, a known board route and material in stock. That avoids opening a customer-specific coated-paper roll and avoids some new setup requirements. A blank stock option is therefore a different procurement route from a custom printed, custom-size order.

The current UGI Packging route is printing, die cutting, folder-gluing and inspection. Each stage can create process loss, and the final accepted quantity depends on the combined result rather than on paper purchasing alone.

UGI Packging records combined loss of approximately 8-12% for the stated route. The causes include printing registration loss, die-cut edge and trim waste, glue-opening rejects and cracking near the carrying-handle position. The exact allowance remains job-specific.

The handle adds extra cutting, creasing and a narrow paper area that must survive folding and forming. UGI Packging identifies cracking near the handle position as a specific loss point for the stated children meal-box structure.

For a 2,000-piece finished requirement, UGI Packging may plan production of approximately 2,200-2,400 pieces so that the accepted quantity remains available after make-ready and process loss. The 8-12% combined loss figure and the planned production quantity are separate planning descriptions and should not be forced into one denominator.

No. A larger order spreads fixed material, die and setup requirements over more saleable boxes, but printing, die cutting, gluing and inspection still have process loss. The economical production quantity improves the allocation of fixed preparation cost; it does not make waste disappear.

Provide the food type, oil and water exposure, contact side, contact duration, hot or cold use, storage conditions, intended market and any required declaration or test documents. UGI Packging can then confirm the board, coating and complete construction instead of quoting from the word food-grade alone.

Compare a suitable blank stock option, a custom-size printed option and the actual material route. Ask for the board and coating specification, material purchasing unit, die and plate preparation, expected process allowance and the accepted finished quantity.
