What Is Co-Packing? How Brands Use 3PL Co-Packing Services To Scale DTC and Amazon Sales

Co-packing (short for contract packaging) is the process of outsourcing your product packaging to a third party — typically a 3PL partner like MyFBAPrep. It includes everything from:

  • Bundling multiple SKUs into a single sellable unit
  • Applying FNSKU or UPC labels
  • Adding marketing inserts
  • Assembling kits or multi-packs
  • Prepping temperature-sensitive goods for cold chain delivery
  • Wrapping, boxing, bagging, or palletizing for Amazon or DTC

Whether you’re scaling up or launching a new SKU, co-packing frees your team from labor-intensive manual work while ensuring compliance with Amazon’s ever-changing rules.

Co-Packing vs. Kitting: What’s the Difference?

Many brands use the terms co-packing and kitting interchangeably — but there’s a subtle difference:

  • Kitting = Pre-assembling products into sets (ex. Shampoo and conditioner bundle)
  • Co-packing = Full-service packaging, including labeling, compliance, shrink wrap, etc.

MyFBAPrep offers both — with standardized processes at over 100 warehouses globally.

Who Needs Co-Packing Services?

Co-packing is critical for:

  • Amazon Sellers – Avoid FBA rejection with compliant packaging, labeling, and bundling.
  • DTC Brands – Create retail-ready kits or ship bundled offers with personalized inserts.
  • Subscription Box Companies – Assemble monthly boxes with SKUs from multiple suppliers.
  • Retail + B2B Brands – Package SKUs to meet retailer or distributor requirements (e.g., Costco, Target, QVC).
  • Cold Chain Brands – Ensure perishable goods are prepped and shipped in temperature-controlled packaging.

If you’re prepping hundreds (or thousands) of units per week, outsourcing this work is a no-brainer.
