Omcan Polypropylene Lid for 58552-734 Stackable Pizza Dough Proofing Boxes

Sized exclusively for the 18" x 12.75" x 3" proofing box at SKU 58552-734, this lid seals that box. Other dough box dimensions need their own matching lids, all visible in the commercial bakery equipment selection.

Without a sealed lid, dough surface dries out in cold proofing, leaving a tough skin that ruins the final pizza crust. The lid maintains humidity inside the box and lets units stack without contamination.

The lid creates a close press-fit rather than a vacuum seal, which is appropriate for dough proofing since dough must release some CO2 during fermentation. A full airtight seal would over-pressurize as the dough rises.

Wash with warm soapy water, then air dry before reuse. Avoid commercial dish machines, since the high-heat cycle can warp the polypropylene and break the fit.

Polypropylene is lightweight, won't shatter when dropped, and seats correctly on the box rim every time. Glass would crack with daily handling, and metal corrodes in the humid environment of a walk-in cooler.

Don't expose to direct flame, hot oil, or oven temperatures, all of which deform the plastic. Inspect for cracks before each use, since cracks ruin the seal and let dough dry.

Coverage is 30 days from purchase date for manufacturing defects. For more pizza-program tools, browse the bakery equipment range at Zanduco Canada.
