Determining what will happen to packages during distribution is a complex task requiring a variety of skills and experience. A trial-and-error approach is never optimal so it is important to evaluate all possible variables that may negatively impact a packaging strategy and develop a process-driven methodology to avoid rework and expensive mistakes.
This article offers an overview of three crucial factors often overlooked when designing a packaging strategy for distribution.
Understanding Your Distribution Environment
Mapping the logistics network from the manufacturer to the point of sales and all points of contact in between should be the first step of packaging design for distribution.
Three important factors are often analyzed too superficially:
Reconsider Product Design
Experience shows that distribution damages are drastically reduced if packaging engineers are involved early in the design of a product. If a product is damaged during either testing or a real shipment, packaging is the first thing engineers usually look to improve. A new material, improved dunnage, or a different container are all tempting options to try to solve the problem quickly. However, a distribution failure can also reveal a weakness in product design. For example, if a corner is too sharp or the selected material does not offer sufficient resistance to fatigue.
Offsetting such structural weaknesses by changing the packaging strategy may come at a high cost and it could be cheaper to start over and re-design the product, especially in the long term.
Product designers and packaging engineers should work together rather than in silos.
Do Not Underestimate Environmental Factors
Compression, vibration, and shock are the most observed factors in packaging distribution testing. While these are surely aspects to be taken into consideration, the environment is often a silent killer.
For example, the stacking strength of a corrugated box can be reduced by as much as 20% if the relative humidity goes from 0% (dry) to 50%. Similar results apply for fatigue and other structural properties. Heat can increase ductility in polymers or increase the viscosity of water-based inks, causing smearing of the artwork.
If transportation happens across different climate zones, taking environment into consideration is a must for a solid distribution strategy.
Think Ahead when Selecting Primary Packages
There is usually a bias toward primary packaging when allocating investments on a packaging strategy for a given product. The reason is simple: the primary package is seen as way to deliver a brand’s value proposition. In contrast, secondary/tertiary packaging are perceived as pure means of transportation with little value for consumers. This approach can lead to critical distribution failures.
A primary package designed to go into a specific RFC may not fit well into a different corrugated box or a shrink bundle. Structural integrity, dunnage and headspace are all variables that may play a role and are difficult or expensive to adapt on-the-go.
Thinking about all levels of the packaging hierarchy up front makes packaging design more efficient as well as cost-effective.
In addition to selecting a package that is robust enough to protect the product throughout the distribution environment, one factor that often gets overlooked during package design is scalability.
Though an effective packaging strategy should work given the current outlook of a business (existing volumes, clients, distribution channels etc.), it is also important to take future scenarios into consideration.
Is the business projected to grow sharply in the next five years? Is it expanding to new geographic areas around the globe? Will other products or handling technologies be added to the current portfolio? These are all important questions to ask at the beginning of the design phase to avoid the pitfalls of a short-sighted packaging strategy.
Here are few examples:
- An increase in volume of product shipped may lead to the necessity of stacking products with an additional layer in the warehouse. This may ultimately lead to static compression failures if not adequately planned for.
- Shifting from LTL to FTL may require a different unitization strategy (e.g. stacking more boxes per pallet requires more robust shrink wrap).
- Adding a new client from a tropical country can lead to distribution failures from humidity and heat, as described earlier.
If a business is planning to expand in the next five years, now is the most convenient time to take corrective actions and avoid costly packaging strategy changes along the way.
Involve Customers and Carriers Early
Testing is an effective way of predicting the performance of packaging in its distribution environment. Amazon, for example, has developed its own testing methodology and technology to drastically reduce damages due to transportation. Amazon suggests that its packaging selector reduced product damage rates by a staggering 24%.
While this technology is proprietary to Amazon, the methodology behind it is something other companies can learn from. Unless products are shipped through a heavily regulated channel, a solid testing strategy should be developed by the packaging design team. Even if your testing is based on standards developed by organizations like ISTA, it is important to involve customers and carriers early in the design process.
The key factor that businesses tend to miss is that testing is done in a lab, while products are shipped in the real world. How roughly will the product be handled by humans? What is the maximum temperature that will be reached inside a container? What is the vibration profile that most accurately mirrors the one of a specific distribution mode? While the packaging design team can surely answer these questions with estimated values, the feedback from customers and carriers is a crucial step that will help you avoid costly mistakes.
Moreover, retrieving real world information on distribution channels can be made automatic with supply chain visibility tools. This technology uses sensors to monitor packages during transportation by collecting real time data such as temperature, humidity, shock, light and location. This provides packaging engineers with accurate data on which they can build a successful distribution strategy.
To summarize, it is important that the packaging design team leaves the lab often to get a firsthand view of what happens to the packages at all touchpoints along the supply chain. They’re likely to discover surprises that lab testing won’t reveal.
It is always difficult to predict what will happen to packages as they move through the supply chain and experience increased hazards. Incorporating these three concepts early in the design of a distribution strategy is a simple but effective way to avoid unwanted and expensive blunders.
In order to ensure your package will arrive at its destination intact, leverage experts who have knowledge of regulatory standards, package validation and distribution qualification to avoid wasting critical time or experiencing expensive pitfalls.
