OEM vs ODM vs Custom Mould: How to Develop Your Own Food Packaging Design

How to develop private-label food packaging: OEM, ODM and custom mould compared, tooling cost drivers, development timeline, sample approval and how to protect your design.

By FoodPack Source Engineering Team · Updated 2026-11-02 · 4 min read

Many food brands start by buying stock packaging and later want something that is clearly theirs: a distinctive tray shape, a lid that fits their line, or a pack sized exactly to their product. The route to that goal depends on how much of the design you own, how much volume you can commit and how long you can wait. This guide explains the three main models, what drives tooling cost and how to run development without surprises.

Three Models Compared

ModelWhat you provideWhat the factory providesBest for
Stock item with your print (private label)ArtworkExisting mould and materialFastest, lowest commitment; see the custom printing guide
ODM (factory design, your choice)Requirements, selection and brandingExisting designs and engineering support, possible modificationDifferentiated look without full tooling cost
OEM / custom mouldDrawing or sample and specificationNew mould, production, QCUnique shape, exclusive design, larger volume

Most brands should start with the first or second model, prove demand, and move to a custom mould when volume supports it.

What Drives Mould Cost

  1. Process. Thermoforming moulds are generally less expensive than injection moulds, but suit different geometries and wall thicknesses.
  2. Cavity count. More cavities mean higher mould cost but lower unit cost at scale.
  3. Size and depth. Larger, deeper items need bigger tooling and more complex draft angles.
  4. Surface finish and detail. Embossing, textures and tight tolerances raise cost.
  5. Materials of construction. Aluminium moulds are cheaper and faster but wear sooner than steel moulds meant for very high volume.
  6. Complexity. Undercuts, hinged lids and multi-part assemblies need extra engineering.

Ask the factory for the mould fee, expected life in shots, who owns the mould, and whether a fee is refunded or amortised over volume.

Mould Ownership and IP

Agree in writing who owns the mould, where it is stored, whether it can be used for other customers and what happens if you change supplier. A common arrangement is that you own the mould physically but it stays at the factory, with an exclusivity agreement for your design. Register design rights where you sell where it makes sense, and keep your drawings and files under confidentiality. Do not assume a shape is yours just because you paid for development.

Development Timeline

  1. Brief and specification. Product, fill volume, temperature, closure, food type, target market, volume. Use the checklist in the MOQ and lead-time guide.
  2. Concept and drawing. 2D drawing or 3D file, with dimensions and tolerances.
  3. Prototype. A quick sample, often 3D-printed or machined, to check fit and look.
  4. Mould making. Typically the longest stage.
  5. First samples (T1). Test the real food, lid fit and stacking. Expect at least one round of mould adjustment.
  6. Approval and pilot run. Sign off dimensions, weight, material and colour.
  7. Mass production. With QC specs agreed. See the AQL inspection guide.

Designing for Manufacturing

  • Draft angles. Thermoformed and injection parts need tapered walls so they release from the mould and nest.
  • Wall thickness. Keep it uniform; thin corners are the first to crack.
  • Nesting and stacking. A good design nests tightly when empty and stacks stably when full. This affects freight cost as much as unit price.
  • Sealing flange. If using film, design a flat, wide flange. See the leak-proof guide.
  • Material fit. Choose the base material first (see PET vs PP vs rPET), because it changes tolerances and shrinkage.

Sample Approval Checklist

  • Dimensions against drawing and tolerances.
  • Weight in grams, which controls cost and strength.
  • Fit with lid, film and sealing equipment.
  • Real-food, heat, freezer or leak tests for the intended use.
  • Colour and surface finish under real lighting.
  • Food-contact documents for the exact material and pigment.

Quality and Compliance

A new design needs its own migration and compliance documentation, since changes in resin, pigment or additives alter the test basis. Our factory operates under ISO 9001:2015 and BRCGS Packaging, and SGS third-party reports can be arranged for the finished product. For the legal frameworks see the FDA and EU guides. If you plan an eco claim, check the claims guide first.

How to Start

Send your drawing or a physical sample, the food and fill volume, annual volume and target market through the contact page. We will tell you whether an existing design can be adapted, or whether a new mould is worth it, with a cost range and timeline.

Buyer FAQ

What is the difference between OEM and ODM packaging?
OEM means the factory makes a design you supply, usually with a new mould. ODM means you choose and adapt a design the factory already developed, which is faster and cheaper.
How much does a custom food packaging mould cost?
It depends on process, size, cavity count and finish, so ask for a quotation based on your drawing. Ask also about mould life and whether the fee is amortised over volume.
Who owns the mould?
This must be agreed in writing. Commonly you own it and it stays at the factory under an exclusivity agreement for your design.
How long does custom mould development take?
Allow time for drawing, prototype, mould making, first samples, adjustment, approval and a pilot run. Mould making and sampling are usually the longest stages.
Do I need new compliance testing for a new design?
Yes. A new resin, pigment or additive changes the test basis, so request documents and test reports for the exact material used in your design.
