Custom Airtight Silicone Container Manufacturer
From your sketch to a finished product, no minimum order.
We manufacture airtight silicone containers, silicone food containers, and silicone storage containers for brands, retailers, and industrial buyers. We handle design review, tooling, prototyping, and production in-house. A low-cavity steel mold runs from a single prototype, so there is no minimum order. Material grade, lid construction, seal performance, and branding are set per project.
The Right Silicone For Your Product
We select the material grade for your application before production begins. Silicone is our primary material, sourced from premium European and US silicone, plus qualified domestic partners, with full batch traceability. For projects with specific compound requirements, we also work from a library of 32 rubber compounds.
Material Properties
Standard containers are produced using food-grade, platinum-cured silicone.
- -55°C to +250°C, freezer, microwave and oven safe
- Airtight and odor-proof, no leaks, no smells
- Flexible without cracking, warping, or degrading
- Hypoallergenic, non-toxic, body-safe out of the mold
- Shore A 10 to 80, set per project
Material Grades Available
Material grade is confirmed before production, against the application and compliance requirements.
For higher purity, USP Class V and VI certified silicone is available on request. Share your application requirements and we will confirm the right grade and certifications.

Mold Making and Material Sourcing
All molds are CNC machined in-house at our Dongguan facility. Steel is our default mold material — steel holds its dimensions across the full run, so one low-cavity tool runs your market test and, for small orders, your production. Aluminum is available, but it does not cut cost or time, so we default to steel. Your mold is your property, stored at no charge for future orders. Design files are handled with restricted access and are not shared externally.
Silicone materials are sourced from Elkem, Dow, and DuPont and from qualified domestic partners, with full batch traceability and TDS documentation. Every batch is verified before production begins. Optional third-party certifications are available on request.
Frequently Asked Questions
Common questions from brands and buyers about custom silicone container manufacturing, materials, and lead times.
What is the minimum order quantity?
There is no minimum order. A low-cavity steel mold runs a single prototype, then 200 pieces for a market test. For small orders we design one tool that runs prototype and production together. The tooling split is advised per project, based on size, geometry, and volume.
- Single prototypes accepted
- 200 pieces for a market test
- One tool for small orders
- Tooling advised per project
Can I have my logo on the lid?
Yes. Your logo can be engraved or embossed directly into the mold for a permanent finish.
- Engraved or embossed on mold
- Interchangeable logo insert plate
- Future logo updates need only a new insert
- Laser engraving also available
Can I produce the same container in multiple colors?
Yes. Multiple colors can run from the same mold in a single order, at no additional mold cost.
- Full Pantone color range available
- Specify your color split and codes
- No extra tooling cost for color changes
- Matte or gloss finish per color
