The Alternatives, Assessed Honestly: Paper, Board, Fibre and Service Models

Escaping Annex V is the beginning of an alternative's duties, not the end of its assessment. Every substitute lives under the general framework - substances, grades, content where applicable, minimisation, labelling - and under the honest comparison: does the total profile improve? The failure pattern to avoid is burden-shifting in its standard costumes: plastic film replaced by a heavier laminate that recycles worse; a portion pack replaced by a dispenser run so badly that food waste doubles; a produce punnet replaced by a fibre format whose moisture failure writes off the berries. Each has happened, in print, under sustainability headlines.

This guide gives the assessment method and applies it to the list's main substitute families.

Five questions, answered with evidence proportionate to the volume. Function: does it perform (protection, shelf life, line speed, hygiene) at the level the incumbent's data set? Profile: its regulated position - grade, substances, content story, labelling - computed, not assumed. Footprint drivers: the terms that dominate its comparison (weight, food-waste delta, washing and logistics for service models) identified and roughly quantified. Cost: full cost at your volumes, including conversion and the service labour where models change. Failure modes: how it goes wrong in your operation, and whether those modes are managed or merely hoped away. An alternative that passes all five is a conversion plan; one that passes four is a pilot with the fifth as its research question.

Paper and board substitutes (bands, sleeves, carriers, trays): strong grades where fibre streams are real, watch wet-strength and window/laminate creep - a board carrier plastic-laminated back into unrecyclability has changed its costume, not its profile. Moulded fibre: excellent where moisture is managed, variable where it is not; its sourcing and additives belong in the substance inventory like any input. Service models (dispensers, serviceware, refill): the footprint lives in the operation (wash energy, loss rates, food waste), so their assessment is an operations audit wearing a packaging question's clothes - the reuse station's numbers are the evidence. Material switches within plastic (thicker, different polymer): outside several listings by construction, but the most suspect family under this method - the listing's purpose is rarely honoured by a heavier version of the listed thing, and the review clause is watching it.

Converted ranges attract marketing, and the claims framework applies at full strength: the alternative's virtues stated specifically (the material, the system, the measured change), never as a halo over the range ('plastic-free' where adhesives and windows remain plastic, 'sustainable packaging' as a genre claim). The conversion file and the claims register update together - the assessment this guide prescribes is the substantiation the claim will need when the photograph is sent. Businesses that convert quietly and claim precisely will find the transition an asset; the reverse order manufactures the enforcement story of 2031 from the good work of 2029.

The five questions outlive the list: every future format decision in the portfolio - new materials, new service models, the next review's candidates - deserves the same assessment before the marketing department names it. Keep the method as a template in the design system, with the evidence standards the stations have set, and the portfolio's conversions become a capability rather than a series of emergencies. The businesses that will handle the list's growth best are not the ones with the best answers today; they are the ones whose questions are already standard.

A multipack conversion assessed by the method, compressed: the incumbent film at 4 grams per bundle, unrecyclable in practice, fee-exposed and listed. The candidate board carrier at 14 grams: function proven on the line at 92 percent of film speed after tooling; profile - grade A construction in fibre, substance inventory clean, labelling surface enlarged (a claims opportunity and a claims risk, registered); footprint drivers - heavier per unit, decisively better end-of-life, no food-waste term; cost - material up, line cost neutral after the packer conversion, fee and brand terms favourable; failure modes - wet-strength in chilled cabinets, trialled through a summer with a board specification change as the result. Verdict: convert, with the wet-strength specification as the pilot's legacy. Five questions, one page, a decision that can be defended in any room it is ever questioned in.
