What is the difference between a co-packer and a contract manufacturer?

A contract manufacturer typically develops or scales your formula and makes the product, while a co-packer focuses on filling, labeling, and packaging—sometimes both in one facility. Many partners do both. The key is matching scope to your needs: bring a finished formula, or get help formulating it. AJ Cosmo Labs connects you to formulators, co-packers, and packaging suppliers in the same network.
