The Next Wave of Secondary Fiber-Based Packaging

For secondary fiber-based packaging—the outer layer that holds products already contained in primary packaging—that performance includes product protection, moisture resistance, durability, manufacturability, transportation efficiency, and shelf-ready presentation.

Performance Comes First

Replacing plastic or foam is rarely as simple as swapping one material for another. Effective fiber-based secondary packaging maintains quality throughout the supply chain. That becomes especially important as fiber-based materials move into applications traditionally dominated by plastic and foam, where packages may be exposed to moisture and temperature fluctuations, refrigerated or freezer storage, and repeated handling. Designing for those conditions helps fiber-based materials maintain package integrity.

Traditional lab testing can provide an important indication of performance, but it may not account for the full range of supply chain realities. Comprehensive testing and simulation informed by actual transportation, storage, handling and environmental conditions can provide a more complete view of how a fiber-based package will perform and help reduce the risk of damage and waste.

Secondary Packaging Decisions Are Increasingly Driven by Total Cost of Ownership

Brands increasingly assess secondary packaging through a total-cost-of-ownership lens rather than by focusing exclusively on material costs. This broader view considers how packaging influences pallet utilization, transportation efficiency, storage requirements, product damage rates, manufacturing performance and labor costs while balancing recyclability and evolving regulatory requirements.

Switching to lower-cost, lighter-weight fiber-based packaging can make sense for many applications. Advances in paper and containerboard can now enable lighter-weight solutions to deliver the necessary strength when the right paper, board combination and structural design are selected. However, lightweighting is not always the best fit.

Consider a warehouse where the bottom layer of a product on nearly every pallet is crushed. What seems like a minor unit-level loss can quickly become a major supply chain cost. The fix for fiber-based secondary packaging may require a different board combination, an improved package design, or better pallet configuration. Regardless, the takeaway is that the lowest-cost package isn’t always the lowest-cost solution when switching to fiber-based solutions.

Hidden costs can also emerge when incorrectly designed secondary packaging of any material encounters other real-world supply-chain conditions. Failures can occur during transportation and handling, where environmental conditions and physical stresses place significant demands on packaging systems. Moisture exposure and prolonged storage can also gradually reduce package performance if those conditions are not incorporated into the design process. Today, the most successful companies are ensuring that their fiber-based secondary packaging can meet these challenges.

Primary packaging changes must also be considered when designing fiber-based secondary packaging. When a company reduces plastic or otherwise modifies a bottle, container or other primary package, the secondary packaging may need to provide additional protection or support. Keeping secondary packaging providers informed of planned primary-package changes allows the complete system to be evaluated before implementation.

This broader view prompts brands to assess secondary packaging beyond its upfront material cost. The most effective packaging solution isn’t always the package with the lowest upfront material cost, but the well-designed option that minimizes costs across the broader distribution network.

Early Collaboration Leads to Better Secondary Packaging Outcomes

Whether a company is using plastic, foam or fiber-based secondary packaging, one of the biggest misconceptions surrounding packaging redesign is the assumption that a single approach can work across varying products, markets and distribution models.

In reality, packaging effectiveness depends on a wide range of variables. Product characteristics, primary packaging, manufacturing equipment, transportation conditions, storage environments and retailer requirements all influence what constitutes the right fit. For companies switching to fiber-based packaging, paper basis weight is one consideration, but it does not define performance on its own. Paper properties, board combinations, structural design and supply chain conditions must be evaluated together.

Consider liquid packaging applications. Teams evaluating solutions for commercial beverage distribution often encounter a complex set of variables, including machinery capabilities, available facility space, throughput requirements, primary-container performance and operating budgets. Each factor influences which secondary packaging format will deliver the strongest results.

That complexity makes early collaboration during the design phase essential, including when a company is switching to fiber-based secondary packaging. Packaging engineers, designers, operations leaders, packaging suppliers and equipment partners each contribute valuable insight into how the complete packaging system will perform in real-world settings. The earlier those stakeholders become involved, the easier it becomes to identify potential challenges, validate assumptions, and optimize package integrity throughout the supply chain.

Leading organizations increasingly walk the supply chain with packaging partners to better understand storage conditions and operational constraints. Some are also leveraging predictive modeling tools to evaluate how packaging may perform under varying conditions before implementation. As more companies switch to fiber-based secondary packaging, the most trusted designers of corrugated solutions are working closely with today’s top brands to ensure product protection throughout the supply chain.

Packaging Winners Think Beyond Materials

As companies explore alternatives to plastics and foam, successful secondary packaging designers will look beyond simply substituting material to ensure that fiber-based packaging performs just as well if not better than harder-to-recycle options. The goal is to identify the right paper, board combination and package design to protect products, support efficient supply chain operations, and meet sustainability objectives.

Better outcomes begin with early collaboration among fiber-based packaging experts who can assess real-world performance and total-cost implications before design decisions are finalized. Regular communication also allows changes to a primary container to be incorporated into the secondary packaging design.

The winners in the next generation of packaging innovation won't be the companies that simply replace plastic. They'll be the organizations that successfully replace performance while improving efficiency and supply chain resilience.
