Product Description
The Collapsible Silicone Lunch Box is a reusable food storage and meal transport container that solves the single biggest problem with standard lunch boxes: they take up space even when empty. The silicone body compresses from 7cm to 3cm depth with light hand pressure — more than 57% height reduction — making it practical to carry in a bag, store in a desk drawer, or pack in a travel kit without the bulk of a rigid container.
The container body is molded from FDA-grade silicone that is safe from -40°C to +230°C, meaning it goes directly from freezer to microwave without transfer to another container. The transparent PP lid uses a button-snap closure for a tight, leakproof seal during transport. A vent hole in the center of the lid can be opened for steam release during microwave heating, preventing pressure build-up.
The folding mechanism has been tested through tens of thousands of cycles — the silicone body does not crack, deform, or lose its spring-back after repeated folding. This is a core differentiator versus silicone containers with thinner walls that lose shape over time.

With light hand pressure on the silicone walls, the box folds from full 7cm depth to a 3cm flat profile. The folded form fits easily into a bag pocket, desk drawer, or luggage side compartment. Stacked folded boxes take up minimal shelf space for retailers or storage facilities.
The silicone body meets FDA food-contact material standards. The extreme temperature range means it is genuinely freezer-safe for food prep and storage, and microwave-safe for reheating without transferring food to a separate container — a key convenience feature for office and school users.
The transparent PP lid snaps down via a center button closure, forming a secure seal that prevents leaking during bag transport. The vent hole in the lid center can be opened when microwaving to release steam pressure — preventing the lid from popping or food from splattering.
Both the silicone body and the PP lid are dishwasher safe. The silicone surface does not absorb food stains or odors in the way that plastic containers do, making cleaning straightforward even after strongly flavored foods.
The silicone wall thickness and compound formulation are engineered to maintain elasticity through repeated fold cycles. The fold height is less than half the open height even after extended use — the product does not soften, crack, or deform at the fold lines over its service life.
At 185g with 800ml capacity, this lunch box replaces disposable and single-use containers for daily meal prep. The durable silicone construction extends service life beyond that of standard plastic lunch boxes that crack and stain with repeated microwave use.

Q1: Is the lunch box truly leakproof for transporting soups or sauces?
The PP lid uses a button-snap center closure that forms a tight seal against the silicone rim. The box is designed to be leakproof for normal bag transport of foods including soups and sauces when the lid is fully closed and the vent hole is sealed. We recommend keeping the box upright during transport for liquid-heavy contents.
Q2: Can I heat food directly in the silicone body in the microwave?
Yes. The silicone body is microwave-safe up to 230°C. When microwaving, open the vent hole in the PP lid to release steam pressure. Do not microwave with the vent hole sealed — steam build-up can cause the lid to deform or pop.
Q3: Is it safe to put this in the freezer?
Yes. The silicone body is rated to -40°C and is fully freezer-safe. You can freeze pre-prepared meals directly in the box and transfer to the microwave for reheating without changing containers. The PP lid is also freezer-safe.
Q4: What is the actual folded thickness, and does it stay flat?
The folded height is 3cm — less than half the open 7cm height. The silicone body maintains its folded flat profile under its own weight. It does not spring open unintentionally when packed in a bag or stacked in storage.
Q5: How durable is the folding mechanism — will it crack over time?
The silicone compound and wall thickness are engineered for repeated folding. The product has been tested through tens of thousands of fold cycles with no cracking or deformation at the fold lines. The fold height remains less than half the open height throughout the product's service life.
Q6: Is the silicone FDA certified, and do you have documentation?
Yes. The silicone used in this product meets FDA food-contact material standards. Test reports and compliance documentation are available for B2B buyers upon request. LFGB (EU food-contact standard) documentation is also available for European market buyers.
Q7: What colors are available, and can I order a custom color?
Standard stock colors are Pink, Green, and Cyan-Blue. Mitour supports custom Pantone color matching for OEM orders. Custom colors require 10–18 days production lead time depending on compound preparation.
Q8: Can I order a set of multiple sizes (e.g., small + large)?
Mitour can produce multi-size gift sets and mixed-capacity retail packaging configurations under OEM arrangements. If you require a size other than 800ml, our ODM team can develop a custom mold to your specified dimensions and capacity.
Q9: Can I put my logo on the lunch box?
Yes. Logo options include debossing directly into the silicone body (permanent, durable) and screen printing on the lid or outer silicone surface. For retail packaging, custom box printing with full brand artwork is available.
Q10: What is the minimum order quantity for OEM orders?
MOQ depends on customization level and packaging format. Please contact our sales team with your target quantity, color, size, and logo artwork for a detailed quotation and sample timeline.
