Better communication, greater transparency, demand flexibility, and consistent quality paired with proactive innovation. Those are the four fixes CPG brands said they need most from co-pack partners in a 2026 Packaging World reader survey.
The survey respondents weren't dissatisfied with the co-man model itself. They're confident in outsourcing. What they're frustrated with is how partnerships actually function once the contract is signed. If you're evaluating co-packers right now, or quietly benchmarking the one you have, these four areas are where the gap tends to show up.
Why Is Communication the #1 Complaint About Co-Packers?
Because most co-packers default to reactive communication, and brands are tired of chasing updates. This was the top concern in the survey by a clear margin. One respondent described co-packers as "notorious for being poor communicators." Another said they were "ghosted for weeks," adding that the silence "adds to uncertainty and stress."
The pattern is consistent: brands want dedicated liaisons focused on their business, not shared account reps juggling dozens of customers. They want production timelines communicated "from start to finish," not piecemeal updates when something goes wrong.
If you're evaluating a co-packer, the question isn't "do you communicate well?" Everyone says yes. The better questions: Who is my named point of contact, and can I reach them directly? What does your standard production reporting cadence look like? How quickly do you escalate issues, and to whom? If the answers are vague, the communication probably will be too.
What Does Transparency Actually Look Like in Contract Packaging?
It means visibility into both costs and operations, not just final invoices and ship confirmations. Survey respondents specifically called for "clearer discussions around costing and price increases" and "the ability to show up and inspect any time."
This goes beyond good communication. Transparency is structural. It's whether your co-packer uses standardized, documented processes or relies on institutional knowledge that lives in one operator's head. It's whether pricing conversations happen proactively before increases hit, or whether you find out on the next invoice. It's whether you can walk the floor unannounced and see your product running the same way it ran during the qualification run.
Some respondents also flagged the need for standardized processes like uniform ingredient ordering. The underlying message: open books and open doors build trust. Opacity, even unintentional, erodes it.
When you're asking questions during evaluation, pay attention to how a co-packer responds to pricing questions. Do they walk you through the cost structure, or just give you a per-unit number? A partner who explains their pricing builds a relationship you can plan around. One who guards it creates a relationship you'll eventually outgrow.
How Flexible Should a Contract Packager Be With Demand Swings?
Flexible enough to scale with your business reality, not just your forecast. Survey respondents said co-packers need to respond faster to volume changes, optimize for variable demand, and accommodate smaller production runs.
This is one of the more structural challenges in the co-pack model. Many larger co-packers are built around long, predictable runs. Their efficiency depends on it. When your Q4 holiday surge requires 3x the volume and Q1 drops to a fraction of that, the friction shows up as extended lead times, minimum order pushback, or unfavorable pricing on smaller runs.
The honest reality is that smaller runs do cost more per unit at any co-packer. That's economics, not a red flag. The red flag is a partner who can't or won't run them at all, or who treats variable demand as your problem rather than a shared planning challenge.
Questions worth asking: What's your minimum run size, and what happens to pricing at different volumes? How much lead time do you need to scale up 50%? What does your capacity utilization look like right now? A co-packer running at 95% utilization has no room for your surge. One with headroom built into their model is structurally better positioned to absorb your variability.
What Is Quality Drift and Why Does It Keep Happening?
Quality drift is when the first production run meets spec and every subsequent run gets a little further from it. One survey respondent put it directly: "First runs are always good, but subsequent runs more lax."
This happens for predictable reasons. During onboarding, your account gets senior attention, detailed setup documentation, and careful quality checks. After month three, operators rotate, documentation gets abbreviated, and the self-audits that caught issues early start getting skipped. The product still ships, but the precision that earned your approval erodes gradually.
The fix isn't more inspections on your end, though facility visits help. The fix is operational discipline that doesn't depend on which shift is running your job or how long you've been a customer. Daily production huddles, standardized work instructions, self-audit protocols, and KPIs that get reviewed on run fifty the same way they got reviewed on run one.
If you're evaluating a co-packer, don't just ask about their quality systems. Ask what their fill rate and complaint rate look like across all customers over the past 12 months. If they track it and share it readily, that tells you something. If they can't produce the number, that tells you something too.
Should Your Co-Packer Be Bringing You New Ideas?
Yes, and the survey confirms brands expect it. Respondents want proactive innovation: new packaging technologies, fresh formats, and ideas brought forward without being asked.
The gap here isn't usually capability. Most co-packers see opportunities on the line every day: a format that would reduce waste, a configuration that would improve shelf presence, a material substitution that would cut cost without sacrificing quality. The gap is process. Without a structured mechanism for surfacing those ideas to the customer, they stay on the production floor.
When evaluating a partner, ask for a specific example: "Tell me about an idea you proactively brought to a customer in the last six months." If they can't point to one, innovation isn't part of their operating model regardless of what the pitch deck says.
The survey's bottom line resonated with a broader theme: brands want to trust that external partners are as committed to quality as their own in-house teams. When that alignment exists, the co-packer relationship becomes what respondents described as "a growth engine for both sides," not just overflow capacity.
How to Use These 4 Areas in Your Evaluation
Turn each one into a specific question set during your next co-packer review or RFP process.
Communication: Who is my dedicated contact? What's the escalation path? What reporting do I get without asking for it?
Transparency: Walk me through your cost structure. Can I visit unannounced? How do you handle price increase conversations?
Flexibility: What's your minimum run? What's your current utilization? How fast can you ramp 50% up or down?
Quality + Innovation: What's your fill rate across all accounts? Show me an idea you brought to a customer unprompted.
These questions work whether you're sourcing a new partner or holding your current one accountable. A co-packer who answers them confidently with specifics is probably operating the way you need. One who deflects to capability lists and certifications may not be. For a more comprehensive evaluation checklist, see our guide on questions your contract packager should answer.
Frequently Asked Questions
What are the biggest complaints brands have about contract packagers?
A 2026 Packaging World survey identified four: poor communication and responsiveness, lack of cost and operational transparency, inability to handle demand variability, and quality drift after initial production runs paired with a lack of proactive innovation.
What does transparency mean in a co-packer relationship?
It means visibility into cost structures before price increases happen, the ability to visit and inspect operations at any time, and standardized processes that don't vary by shift or operator. Brands in the survey specifically asked for clearer pricing discussions and open-door policies.
How do I know if my co-packer is maintaining quality after the first run?
Ask for ongoing fill rate and complaint rate data across all customers, not just your account. Quality drift typically emerges after month three to six. Consistent metrics over time indicate operational systems are in place, not just a strong onboarding effort.
How flexible should a co-packer be with order size changes?
A solid contract packaging partner can handle meaningful volume swings quarter to quarter. Smaller runs will cost more per unit, which is normal. The red flag is a partner who won't run them at all or who treats your demand variability as an inconvenience rather than a planning input.
Should I expect my co-packer to suggest new packaging ideas?
Yes. The survey confirmed brands expect proactive innovation from co-pack partners. The differentiator is whether a co-packer has a structured process for surfacing ideas, or whether innovation only happens when the customer asks.
What questions should I ask when evaluating a contract packager?
Focus on operational specifics: Who is my dedicated contact? What reporting do I get without asking? Walk me through your cost structure. What's your fill rate across all accounts? Tell me about an idea you proactively brought to a customer recently. These questions reveal the working relationship more than any capability presentation will.
At Industrial Packaging, these four areas are central to how we've built our contract packaging operations.
