custom food grade round cake container with lid pet disposable round birthday cake box
Product Introduction
This PET round cake box from Rosinpack consists of a heavy‑duty black base and high‑clear ribbed dome lid. Vertical reinforcing ribs on the dome lid and circular reinforced structure on black base greatly improve compression resistance.
As a thermoforming blister manufacturer, Rosinpack delivers full‑in‑house service including mold design, sheet selection, deep‑draw thermoforming and mass production. Multiple inch‑size options from 6‑12 inch are available. All items meet global food‑contact standards for local bakery shops and export‑oriented food factories.
