Collapsible Body · Locking Lid · 4 Stocked Colors
Round Foldable Silicone Lunch Box
Most lunch boxes earn their shelf space when full and lose it when empty — a rigid box takes the same bag space going home as it did coming in. This one collapses: the round silicone body folds flat under its locking lid to a fraction of its expanded height, so it commutes empty, stacks by the dozen in a drawer, and ships dense — a real freight advantage at container scale. Expanded, it is a serious container: freezer-to-oven silicone body (lid off to heat), a locking lid with vent for microwave days, and four stocked colors that run any Pantone on the same tool. For program buyers it is the space-saving anchor of a meal-prep line from the factory that runs the mold.

Professional-Grade Round Foldable Silicone Lunch Box for Commercial Use
The body is a food-grade silicone cylinder with molded accordion rings, so it telescopes from full height to flat in one press, and the locking lid clamps the rim with side tabs for commute-proof sealing. The round footprint fits bowls and bag corners better than rectangles, cleans without corners to scrub, and carries the platinum-silicone temperature range: freezer to -40°C, oven to 230°C with the lid removed. Folded stacks click together, which is what makes the box work at volume — in a school-bag drawer or a distributor's carton.
This round box sits in the food-storage shelf of a kitchenware program that already spans bento containers and prep tools from one factory floor — the straight-sided bento trio for desk lunches, this collapsible round for commuters and campers, and the PP lock-lid box for volume programs. Everything runs on identical terms because it comes off the same floor: we are the manufacturer, the tooling is stocked with inventory behind it, four colors are standard with any Pantone on the same tool, and your brand goes on the band or sleeve. Minimums stay at 100 pieces per design.
Daily use is simple: expand, fill, lock the lid — vent it for microwave days and remove it before oven or oven-reheat use, since the body alone is rated -40°C to 230°C. To stow, press the body flat under the lid and it collapses to a fraction of its height. The box rinses or rides the dishwasher with the lid off; no hinge pins or gasket rings to lose. Custom Pantone colors, printed bands and branded packaging are quoted with samples from our China factory, with expanded and folded dimensions in the sample pack.

Custom Silicone Mold Tooling
Silicone tooling is where our own mold shop matters: the cavity, the parting line and the draft angle decide whether a mold releases cleanly for two thousand cycles or two hundred.
- Cavity Design - send a sketch or a 3D file; we return a mold proposal with wall thickness and parting line marked.
- Cure and Hardness - platinum-cured as standard, with Shore A selected for the release behavior you need rather than the cheapest compound.
- Color - Pantone-matched compound, held on file so reorders do not drift.
- Logo - embossed in the steel so the mark is molded into the part and never washes off.
- Mold Fee - credited back against your first bulk production run.
