Kitting is no longer a niche add-on service buried in a copacker's capabilities deck. As Packaging World noted in "Kitting Moves Beyond Hidden-Market Status," kit packaging is becoming an essential service of contract packagers in meeting CPG companies' need to push time-sensitive products to market. Variety packs, promotional bundles, club-store configurations, and seasonal programs are driving a volume of assembly work that most primary production lines cannot absorb without compromising throughput on core SKUs.

Most copackers will tell you they can handle everything. The ones running at 95% utilization in June will still say yes in the RFP. You find out what that actually means in October, when your promotional program is sitting in a queue and your retail window is closing. The question is not whether your copacker has capacity on paper. The question is whether they have built their operation to serve both short-run flexibility and sustained high-volume output, at the same time, without sacrificing one for the other.

Snack food brands are running faster than ever. New flavors, limited-edition collaborations, variety pack expansions, and club store formats are compressing timelines that used to allow months of lead time down to weeks. If your internal production lines are optimized for core SKU volume, they were almost certainly not designed for the mixed-SKU variety pack assembly, overwrap tension calibration, and pallet-level compliance work that retail and club channel growth demands.

Your contract packager's quality failure is your recall. That's the reality every Quality and Compliance leader at a CPG brand carries into a copacker evaluation. Label errors drove nearly half of all U.S. food recalls in 2024, undeclared allergens accounted for 34% of all food recall events that same year, and the average direct cost of a recall runs around $10 million before you count canceled contracts, lost shelf space, and the brand damage that doesn't show up on a balance sheet. When you outsource secondary packaging, you are not outsourcing the liability. Understanding what a credible quality control program looks like at a contract packager, and how to verify it before you commit, is the most important due diligence you can do.

Club stores like Costco, Sam's Club, and BJ's operate a fundamentally different supply chain than traditional retail, and most copackers are not set up for it. Industrial Packaging builds club packs as a core service, assembling primary-packaged product into club-format configurations that meet warehouse club pallet, labeling, and sustainability requirements before anything leaves the dock.

The real ROI of outsourcing to a contract packager goes beyond per-unit cost savings. It includes floor space recovery, labor redeployment to core production, eliminated capital expenditure on secondary packaging equipment, reduced quality failures and retailer chargebacks, and faster speed to market for seasonal and promotional programs. For a $500M+ CPG brand running multipacks, displays, or club packs in-house, outsourcing secondary packaging typically frees floor space for revenue-generating production, redeploys staff to core manufacturing work, and eliminates annual equipment maintenance on shrink tunnels, case erectors, and labeling lines.
