1. How are evolving e-commerce handling conditions and last-mile delivery risks reshaping the way manufacturers specify corrugated grades and flute profiles for secondary packaging?

Absolutely. E-commerce is more complex: there are more drops, handling events, and unconventional stacking conditions, which have forced us to fine-tune flute selection and board composition much more carefully, always considering the most demanding scenarios. Today, paper combinations are optimized to achieve the required performance levels. Packaging is no longer designed only for pallet transport, but with the courier, user experience, and reduction of delivery incidents in mind.

2. In high-velocity supply chains, how do you balance Edge Crush Test (ECT) strength, light weighting, and cost efficiency without compromising product protection or recyclability?

The key lies in optimizing customer requirements and aligning them with the actual mechanical properties of the box. One of the hardest parts is gathering information about the client’s supply chain. It also involves using the right flute profiles, adjusting paper weights, and optimizing the structure. In many cases, weight can be reduced while maintaining ECT through good structural design. And of course, cost efficiency is always a factor, as no one wants to pay more than necessary for a box.

3. What role does recycled content play in corrugated board performance today, and how do you address concerns around strength variability and moisture sensitivity?

Recycled content is no longer secondary; in many projects it is a customer requirement and an integral part of brand identity, often printed directly on the packaging. Is there variability? Yes. Can it be managed? Absolutely. This is addressed by adjusting recycled fiber ratios and applying specific treatments when required. Today, it is possible to produce 100% recycled corrugated board that fully meets performance requirements, provided it is properly designed. This can be verified simply by noticing the growing number of products carrying certifications such as FSC.

4. How are European plastic ban regulations influencing not just material substitution, but also the overall quality expectations of secondary packaging?

Significantly. In the past, removing plastic was often enough; today, both customers and legislation demand that alternative solutions protect products equally well or better. This has clearly raised expectations for corrugated packaging. A basic solution “just because it is sustainable” is no longer acceptable: it must be sustainable, provide reliable protection, and convey a high-quality perception, while also considering user experience.

5. When replacing plastic protective inserts with corrugated alternatives, what design and engineering challenges most commonly arise, and how are they being overcome?

From a personal perspective, the main challenge is designing a solution in which the product fits properly, especially when dealing with complex shapes. At the same time, the packaging must absorb impacts without relying on plastic, maintain a good appearance, and allow for simple assembly, particularly when integrated into fast production lines. Since corrugated board behaves differently, intelligent folding concepts and controlled deformation systems are used. This requires extensive prototyping, testing, and multiple iterations to reach the optimal solution.

Due to my previous experience, working with 3D product files is extremely helpful; in some cases, I model them myself. Thanks to advances in software, both approaches can be combined to achieve optimal results. In addition, the use of 3D models often avoids the need to ship physical products, reducing emissions—especially for large and bulky items.

6. How do transit durability requirements differ between traditional retail supply chains and modern e-commerce logistics, and what does that mean for corrugated packaging design?

Retail supply chains are more predictable, whereas e-commerce logistics are far less controlled. In e-commerce, packaging is designed with drops, vibrations, and non-ideal compression scenarios in mind, always considering real-world use conditions. Aesthetics and user experience are also becoming increasingly important. Certifications such as ISTA are required by more demanding customers or distributors; although they require greater time and investment, they help reduce claims and returns in the long term.

7. To what extent are brand owners willing to invest in higher-performance corrugated solutions to meet sustainability goals while maintaining margin pressures?

It depends on the customer. When higher-performance corrugated solutions reduce returns, improve the end-user experience, or support regulatory compliance, brands are generally willing to invest. That said, every improvement must be well justified: sustainability creates value, but it always has to be supported by solid figures.

8. How do regulatory compliance, recyclability targets, and lifecycle assessments influence decisions around flute selection and board construction?

These factors are increasingly influential from the earliest design stages. Decisions are no longer based solely on strength, but also on carbon footprint and true recyclability. In some cases, specific customers request the use of certain recycled papers, as they are closely linked to their brand positioning and identity.

9. What innovations in corrugated engineering are enabling manufacturers to phase out plastics while still meeting stringent protection standards for fragile or high-value goods?

The development of optimized microflutes, three-dimensional structures, glue-free locking systems, and integrated reinforcements is enabling corrugated board to behave more like a technical material. It is no longer just a box, but a designed system with well-defined mechanical properties.

10. How do packaging suppliers collaborate with manufacturers to customize corrugated inserts and fittings for product-specific protection at scale?

It is clearly a collaborative process. The customer understands the product; the designer understands the material, its advantages, and its manufacturing limitations; and the sales team acts as a bridge between both sides, ensuring the economic viability of the project. Without this collaboration between all stakeholders, achieving a successful solution is very difficult.

11. In your experience, how has the definition of “optimal packaging” changed as sustainability, logistics efficiency, and regulatory pressure converge?

In the past, the main objective was simply protection at the lowest possible cost, and packaging was often treated as a necessary evil. Today, in many cases, it is considered even before the product itself is fully designed. Packaging is expected to protect the product, be sustainable, comply with regulations, be logistically efficient, and convey a strong brand image. Optimal packaging today is a delicate balance between multiple variables and requirements.

12. How do you see the role of corrugated cardboard evolving as a structural material rather than just a protective layer in secondary packaging?

It is clearly evolving into a structural material. Corrugated board is increasingly replacing plastic components, dividers, and even load-bearing elements. Packaging no longer just accompanies the product; it becomes part of the system.

13. What metrics or testing protocols are most critical today for validating corrugated packaging performance in demanding supply chain environments?

ECT remains important, but it is no longer sufficient on its own. Drop tests, vibration testing, dynamic compression, and moisture performance are becoming increasingly critical. In addition, more e-commerce-specific testing protocols are being used, as they better reflect real supply chain conditions. In many cases, specialized laboratories are required to carry out demanding certifications such as ISTA.

14. Looking ahead, how do you anticipate corrugated packaging solutions adapting further as Europe accelerates plastic phase-out initiatives and circular economy mandates?

Solutions will become increasingly technical and specialized. Corrugated packaging will continue to gain ground, but in a more optimized way and more closely integrated into overall product strategy. The future is not about using more corrugated board, but about using better corrugated solutions and using them as efficiently as possible.
