What to Look for in a Food and Beverage Packaging Partner Before You Sign Anything

Most food and beverage packaging problems with a co-packer don’t show up in the evaluation. They show up after the purchase order is signed, in the production shortfall during Q4, the certification gap that surfaces during a retailer onboarding, the line speed that works at 50,000 cases and falls apart at 300,000. Most buyers don’t know what questions to ask until they’re already dealing with the consequences.

Certifications Tell You What a Co-Packer Is Qualified to Handle, Not Just That They’re Compliant

The certification landscape in food and beverage packaging covers several distinct areas, each mapping to a specific compliance requirement rather than a general standard of quality. Treating all certifications as equivalent is one of the most common mistakes brands make when evaluating a food and beverage co-packer.

AIB Certification

AIB certification covers food safety practices and facility management. The audit score matters as much as the certification itself, because it tells you how consistently the facility operates against the standard. Pflug Packaging has scored Excellent on its last two AIB audits, which is the highest achievable rating.

NSF Certification

NSF certifications cover different ground. NSF Sport is relevant for performance beverage brands making claims that need to be validated for retail or sports organization compliance. A beverage contract packaging partner running supplement or performance drink lines needs to understand these requirements at the production level, not just in the lab.

Organic and FDA Certification

CCOF and USDA Organic certifications are required for brands selling in natural or organic retail channels or making organic claims on packaging. FDA registration is the floor for any food facility, but it is not a differentiator on its own. Pflug’s certifications page lists audit scores, scope, and applicable product categories for each accreditation. The question to ask any co-packer: which of your certifications apply specifically to my product type and my retail channel?

Automation Depth Determines Your Unit Economics at Scale

A line rate per hour does not tell you how your cost structure changes as volume grows. Understanding how a co-packer’s automation setup affects cost per unit at different production scales is one of the most useful things to know before committing to a food and beverage packaging partner.

Manual and semi-automated lines carry higher labor cost per unit. At lower volumes, that may be acceptable because it keeps MOQs flexible. At higher volumes, the math shifts considerably. Fully automated cartoning and tray pack lines reduce cost per case as volume increases, because the fixed cost of the equipment is spread across more units.

Celsius required three cartoning lines at over a million units per month when demand spiked. Del Monte needed two cartoning lines and two tray pack lines simultaneously for 1.5 million units per month. Neither engagement was viable on a manual setup. When evaluating contract packaging services for food brands, ask specifically: what is the automation configuration for my format, and how does unit cost change as my volume scales?

If you’re benchmarking food and beverage co-packing partners against these criteria, Pflug’s team can show you exactly how they perform against each one.

Ask About Spike Capacity Before You Commit to Baseline Volume

Most co-packers can show you what they produce in a normal week. The question that separates a stable long-term partner from one that creates problems at the worst moment is what they can do when your volume doubles in six weeks. What to look for in a co-packer when evaluating spike capacity:

Ask for a peak production example, not a baseline rate. A facility that runs 100,000 cases per week on average may or may not handle 200,000 with four weeks’ notice. Get a specific answer.
Understand what triggers their capacity limit. Is the constraint equipment, floor space, or labor? Each has a different ceiling and a different ramp time.
Find out how they handle overflow. A co-packer that cannot absorb a spike internally will either delay your order or subcontract to a facility you have not vetted.
Know what a capacity miss actually costs you. Missed POs, delayed shipments, and retailer penalties land on the brand, not the co-packer.

When Anheuser-Busch needed to execute a national rollout, Pflug stood up five packaging lines and sustained over a million cases per month. Pflug’s high-volume spike support was built for how to evaluate a co-packing company at scale: what the facility looks like on its busiest week, not its average one.

Warehouse Integration Affects More Than Just Storage

The operational connection between inventory staging and packaging production affects more than logistics costs. When warehousing is integrated with the packaging floor, you can respond to demand changes faster, run shorter production cycles without transit delays, and reduce the coordination overhead of managing a separate third-party logistics provider.

One distinction matters here. On-site warehousing is not the same as 3PL or freight distribution. A warehousing and storage setup co-located with the packaging operation means inbound inventory, staging, production, and outbound palletization happen without a handoff to a separate facility. That removes a layer of dependency from your supply chain and allows for shorter production cycles when demand changes quickly.

Ask any prospective partner: is storage on-site, and how does the staging workflow interact with your packaging lines for short-cycle runs?

How Pflug Packaging Performs Against These Criteria

Pflug Packaging is a food and beverage co-packer founded in 1998, operating contract packaging facilities in Lathrop, CA; Cartersville, GA; and Elwood, IL. Operations are AIB certified with Excellent scores on the last two audits, and hold NSF, CCOF, FDA, and USDA certifications, along with Type 14 and Type 21 licenses for wine and beverage handling.

Pflug has managed multi-line engagements for Anheuser-Busch, Frito-Lay, Pepsi, Celsius, and Del Monte at volumes exceeding a million cases per month. On-site warehousing and staging warehouse capability are integrated with the production floor. Named Frito-Lay’s repacker of the year in 2024.

If the criteria above describe what you’re looking for in a food and beverage packaging partner, Pflug’s team works through the specifics before anything goes to production.
