Packaging: choosing, sourcing and testing

A course on packaging a co-packed product: matching the container to the process, closures and seals, labels that stay on, supplier minimums and lead times, cases and pallets, and testing packaging before a full run.

Paid course

What the course will cover

  1. The container and the process

    Which containers stand up to hot fill, HPP, retort or a refrigerated shelf.

  2. Closures and seals

    Caps, liners and the vacuum a hot-filled jar depends on.

  3. Labels that stay on

    Label stock and adhesives for cold, wet and frozen storage.

  4. Sourcing at your volume

    Supplier minimums, lead times, stock or custom packaging, and who pays up front.

  5. Cases, pallets and freight

    How case size and pallet pattern set your shipping cost.

  6. Testing before the run

    Fill, seal, shipping and storage tests, and why a new size can mean a new process filing.

Who it is for

  • Founders choosing a first jar, bottle, can or pouch
  • Brands moving to a container a co-packer's line can run
  • Anyone whose label or closure failed in storage or in transit
