Packaging Optimisation: Reducing Cost and Environmental Impact
When supply chain professionals list the categories they focus on for cost reduction and efficiency improvement, packaging rarely appears near the top. Procurement teams focus on direct materials. Logistics teams focus on freight rates and carrier performance. Operations teams focus on production throughput and labour efficiency. Packaging sits awkwardly between these functions -- it is procured, it affects logistics, and it is part of the production process -- and the result is that it is often managed with less rigour than the activities that surround it.
This is a significant missed opportunity. Packaging affects transportation cost through dimensional weight pricing -- most carriers now price shipments based on the greater of actual weight and dimensional weight, so a bulky package with low actual weight pays the same as a much heavier shipment. Packaging affects storage density, which determines how much product fits in a given warehouse footprint. It affects handling damage rates: poorly designed packaging that does not adequately protect contents through the full journey from production to end customer generates returns, waste, and customer dissatisfaction. And it carries environmental impact -- in raw material extraction, in the carbon footprint of transportation, and in what happens to the packaging after the customer receives the product.
The business case for packaging optimisation is compelling across all of these dimensions simultaneously. An organisation that reduces packaging dimensions even modestly can reduce freight costs, improve warehouse utilisation, lower damage rates, reduce material costs, and meet sustainability commitments -- all from the same change.
The Packaging Hierarchy
The most useful framework for packaging optimisation is the hierarchy that runs from elimination at the top through reduction, reuse, recycling, and recovery at the bottom. The hierarchy is a priority order: before investing in recycled material content or closed-loop return systems, ask whether the packaging can simply be eliminated or substantially reduced. The most sustainable package is the one that does not exist.
Eliminate: can the packaging layer be removed entirely? Secondary and tertiary packaging -- the cardboard cases and pallet wrap that protect products in transit -- are often present because they have always been present rather than because they are necessary given current product protection requirements and logistics conditions.
Reduce: can the package dimensions, wall thickness, or material weight be reduced while still meeting protection requirements? This is the most commonly achieved optimisation and often delivers the largest financial return.
Reuse: can the package be designed for multiple uses rather than single use? Reusable transit packaging is well-established in some industries -- automotive components, retail fixtures, intra-company logistics -- and under-explored in others.
Recycle: if the package must be single-use, can it be designed for recyclability? This requires considering material choice, multi-material combinations (which are often not recyclable), and the end-of-life infrastructure available to customers.
Recover: energy recovery as a last resort for packaging that cannot be practically eliminated, reduced, reused, or recycled.
Primary, Secondary, and Tertiary Packaging
Primary packaging -- the package that is in direct contact with the product -- is constrained by product protection requirements, regulatory obligations, and branding considerations. Optimisation opportunities exist but are more limited: reducing material gauge where protection testing shows it is sufficient, eliminating void fill where product geometry allows secure packing without it, or switching to materials with a lower weight-to-protection ratio.
Secondary packaging -- the case, tray, or shipper that groups primary packages for handling and distribution -- offers more optimisation opportunity. Case pack efficiency (how many units fit in a case) directly affects palletisation and freight efficiency. A case configured for twelve units rather than ten allows a pallet to carry more product in fewer layers without exceeding weight limits, improving cubic utilisation in both vehicle and warehouse. Working through the mathematics of case configuration with logistics and procurement colleagues frequently identifies opportunities that none of the individual functions had recognised.
Tertiary packaging -- the pallet configuration and stretch wrap -- is often treated as fixed when it is not. Pallet pattern optimisation (the arrangement of cases on a pallet to maximise stability and cubic utilisation) can increase the number of cases per pallet by ten to twenty percent in many configurations. Stretch wrap usage is frequently over-specified: the gauge and number of wraps applied is often set by historical habit rather than actual load stability testing, and reducing it has both cost and environmental benefits.
Working with Co-Packers and Shelf-Ready Packaging
Organisations that use co-packers face an additional complexity: the co-packer's standard packaging configurations may not be optimal for the organisation's logistics network. Co-packer agreements that specify packaging requirements in detail -- dimensions, materials, case configurations, pallet patterns -- and that include the organisation's freight and warehousing cost implications in the discussion are consistently more effective than agreements that leave packaging to the co-packer's standard practice.
Shelf-ready packaging (SRP) -- packaging designed to be placed directly on the retail shelf without unpacking -- has become an expectation rather than a differentiator in many retail channels. Major grocery and mass-merchandise retailers require SRP for most ambient grocery and general merchandise categories. Designing packaging that meets SRP requirements while also optimising for logistics efficiency requires coordinating the retail display requirements with the logistics and production requirements from the outset -- not retrofitting SRP compliance onto a package designed for logistics first.
Customer and regulatory expectations on packaging sustainability are tightening and will continue to do so. Extended producer responsibility schemes are expanding in scope across Canada and internationally, making producers financially responsible for the end-of-life management of their packaging. Retail customers are increasingly specifying packaging sustainability requirements as conditions of ranging or listing. Treating packaging optimisation as a one-time cost exercise rather than an ongoing strategic programme is the wrong posture in this environment: organisations that build a systematic packaging review cadence now will be better positioned when the regulatory and commercial requirements intensify.
