Sustainability tips for packaging that reduce waste and avoid vague claims
Practical sustainability tips start with measurable choices
Sustainability tips for packaging are most useful when they turn broad goals into decisions that can be tested: use less material where performance allows, choose formats that fit existing recovery systems, document recycled or certified content, and avoid claims that cannot be supported. Packaging is visible to consumers, but it also has to protect products, move through logistics networks, meet compliance requirements, and fit waste-management systems. The U.S. EPA Facts and Figures data show that containers and packaging represented 82.2 million tons, or 28.1 percent, of U.S. municipal solid waste generation in 2018. That does not mean every package should simply be lighter or made from a different material. It means each redesign should be judged by product protection, total material use, recycling or reuse practicality, and claim accuracy.
The pressure to improve is not only reputational. In the EU, Regulation (EU) 2025/40 on packaging and packaging waste entered into force on February 11, 2025 and generally began applying from August 12, 2026, with phased rules covering waste prevention, recyclability, labelling, reuse, and recycled content. In the United States, packaging extended producer responsibility remains a state-by-state issue, with seven states having enacted packaging-specific EPR laws by 2026: Maine, Oregon, Colorado, California, Minnesota, Maryland, and Washington. For packaging teams, the practical lesson is straightforward: sustainability has to be designed, measured, and documented before it is marketed.
Start with the job the package must do
A sustainable package still has to do its core job. If a thinner carton, weaker mailer, or lighter pouch leads to more damage, returns, spoilage, or secondary packing, the apparent material saving may disappear. The first step is to define the purpose of each packaging layer: primary containment, barrier performance, shelf presentation, tamper evidence, transport protection, information, branding, or regulatory labelling.
A useful baseline should include the current format’s weight, material type, supplier, recycled content, dimensions, void fill, labels, coatings, inks, closures, and pallets or shipping cases. Teams should also record damage rates, return rates, customer complaints, shipping mode, storage conditions, and the markets where the package is sold. Without this baseline, a redesign can easily become a material swap rather than a measurable sustainability improvement.
The waste hierarchy gives packaging teams a practical design order. Prevention and source reduction usually come first, followed by reuse where the return system is realistic, then recycling or composting where suitable infrastructure exists. Disposal should be treated as the least preferred route, not as an end-of-life plan.
Reduce material before switching materials
Material substitution can help in some cases, but the fastest improvements often come from removing packaging that is not needed. Right-sizing shipping cartons, cutting excess void fill, shortening flaps, using fitted inserts, optimizing board grade, and reducing overwrap can lower material use without changing the whole format. For e-commerce, dimensional weight also matters because oversized packages can reduce transport efficiency even when the material itself is light.
Reduction should be tested, not assumed. Compression tests, drop tests, vibration tests, seal-strength checks, leak testing, shelf-life validation, and transit pilots help confirm that the new format still performs. A package that is 10 percent lighter but doubles breakage is not a responsible improvement.
- Eliminate redundant layers. Check whether a sleeve, insert, wrap, or display component is performing a necessary function.
- Match protection to the channel. Retail shelf packaging, direct-to-consumer mailers, and bulk transport cases face different handling and storage stresses.
- Use fewer components where possible. A simpler structure is often easier to source, fill, sort, and recycle.
- Standardize sizes. A smaller range of box or pouch sizes can improve packing efficiency and reduce errors.
- Watch hidden trade-offs. Lighter materials may need additional coating, lamination, or secondary packaging to deliver the same performance.
Design for recyclability as a whole package
Recyclability is not determined only by the main material. Labels, adhesives, closures, colorants, barrier layers, coatings, inks, metalized films, pumps, windows, and small detachable parts can all affect sorting and reprocessing. A bottle, tray, box, or pouch should be reviewed as a complete packaging system.
The FTC Green Guides in the United States advise that recyclable claims should be qualified when recycling facilities are not available to at least 60 percent of the consumers or communities where the product is sold. That threshold is a marketing-claim guide, not a guarantee that every accepted package will actually be recycled. It is still a useful reminder that technical recyclability and practical recyclability are different.
Industry tools such as the Association of Plastic Recyclers Design Guide and How2Recycle guidance focus attention on the details that influence real recovery. For plastic packaging, these details include resin choice, color, density, labels, adhesives, closures, and barrier materials. For paper-based packaging, coatings, plastic liners, wet-strength additives, food residue, and mixed-material windows can affect acceptance by mills and recovery programs.
Good recycling design usually follows three principles: make the main material easy to identify, avoid components that contaminate the target stream, and give consumers instructions that match the market where the package is sold. If the package is sold in multiple countries or states, instructions may need to be localized rather than treated as universal.
Use recycled, certified, or renewable inputs with documentation
Recycled content can reduce demand for virgin material, but claims need clear boundaries. A recycled-content statement should specify whether it applies to the product, the package, or one component of the package. It should also state the percentage and whether the content is post-consumer or pre-consumer when that distinction matters to buyers, regulators, or voluntary programs.
Supplier documentation is essential. Packaging teams should keep certificates, batch records, chain-of-custody documents, technical data sheets, food-contact declarations where relevant, and any test reports used to support claims. For paper and fiber-based packaging, FSC chain-of-custody certification is one recognized way to verify that certified or reclaimed forest-based material is controlled through the supply chain. For plastics and other materials, buyers should confirm recycled-content quality, contamination limits, color consistency, odor risk, migration requirements, and processing performance.
Renewable or bio-based content should not be treated as a shortcut. A renewable material may still be difficult to recycle. A compostable plastic may contaminate a conventional plastic recycling stream if it is collected incorrectly. A paper package may have higher weight or require barrier coatings. The better question is not whether a material sounds sustainable, but whether it improves the measured outcome for the product, market, and recovery route.
Treat reuse, refill, and compostability as systems
Reuse can reduce single-use packaging, but only when the system achieves enough repeat cycles to justify the added durability, transport, sorting, cleaning, and tracking. A reusable shipper that is lost after one or two uses may perform poorly compared with a lighter single-use alternative. A refill container can work well when the product is concentrated, the refill pack uses substantially less material, and consumers understand the routine. See also: BOX DESIGN.
Before launching a reuse or refill model, teams should estimate return rates, expected trip counts, cleaning requirements, storage needs, reverse-logistics distances, labor, loss rates, and consumer convenience. The design should make reuse obvious. Durable labels, scannable identifiers, easy cleaning, stackability, and damage inspection can matter as much as the material itself.
Compostability is also a system decision. Compostable packaging is most useful when it helps divert food-soiled material from landfill and when composting facilities accept that specific format. Industrial compostability and home compostability are not the same. The FTC Green Guides require competent and reliable evidence for compostable claims, and claims should be qualified when the necessary facilities are not available to a substantial majority of the intended audience. In practice, compostable packaging should not be selected just because recycling is difficult; it should be selected because composting is a realistic end-of-life path.
Keep sustainability claims specific, current, and evidence-based
Packaging communication should be narrower than the evidence, not broader. Broad claims such as eco-friendly, green, sustainable, or earth safe can imply an overall environmental benefit that is difficult to prove. More defensible claims are specific: reduced package weight by a stated percentage compared with a previous format, contains a stated percentage of post-consumer recycled content, designed for store drop-off where accepted, or certified to a named chain-of-custody standard.
Regulatory expectations are moving toward better documentation. The EU Packaging and Packaging Waste Regulation sets packaging waste reduction targets compared with 2018 levels: 5 percent by 2030, 10 percent by 2035, and 15 percent by 2040. It also introduces phased requirements related to recyclability, recycled content, labelling, and reuse. In the United States, state EPR programs vary in definitions, exemptions, producer obligations, reporting timelines, and fee structures. This makes material-level data increasingly important even for companies that are not making ambitious public claims.
The following table turns common sustainability tips into evidence requirements and practical cautions.
| Action | Evidence to collect | Common risk |
|---|---|---|
| Right-size packaging | Material weight, dimensions, void-fill reduction, transit-test results, damage data | Reducing protection without testing can increase returns or product loss |
| Claim recyclability | Material acceptance data, component review, sorting compatibility, market-specific instructions | A recyclable main material may be undermined by labels, coatings, closures, or local access limits |
| Add recycled content | Supplier certificates, percentage by component, post-consumer or pre-consumer status, quality records | A vague claim may not explain whether the content is in the package, product, or only one layer |
| Use compostable materials | Relevant test standard, facility acceptance, consumer instructions, contamination review | Industrial compostability may not help where facilities do not accept the package |
| Launch reusable packaging | Trip count, return rate, cleaning process, loss rate, reverse-logistics data | Environmental benefit depends on repeated use, not on durability alone |
A practical scorecard can keep decisions consistent. Include fields for component weight, material type, recycled or certified content, supplier documentation, recyclability assessment, compostability evidence, reuse assumptions, packaging cost, damage rate, shipping efficiency, claim language, and regulatory notes by market. Review the scorecard whenever a supplier changes, a package is redesigned, a new market is added, or a claim appears on pack or online.
Public reference points behind these cautions include U.S. EPA packaging waste data, the FTC Green Guides, EU Regulation (EU) 2025/40, Ellen MacArthur Foundation progress reporting on plastic packaging, FSC chain-of-custody standards, How2Recycle guidance, and the Association of Plastic Recyclers Design Guide.

Frequently asked questions
What is the first sustainability tip for packaging buyers?
Measure the current package before changing it. Record material weights, components, dimensions, damage rates, shipping performance, supplier data, and existing claims. A clear baseline makes it possible to prove whether a new design actually reduces waste or only changes the material story.
Is recyclable packaging always the most sustainable option?
No. Recyclability is important, but it is not the only factor. A recyclable package that causes product damage, requires much more material, or is rarely accepted in the markets where it is sold may not be the best option. Product protection, source reduction, recovery access, and claim accuracy should be assessed together.
Can a package be called compostable if it only works in industrial composting?
Only if the claim is clear and supported. Industrial compostability should not be presented as home compostability. If appropriate composting facilities are limited in the target market, the claim should be qualified so users understand where the package can realistically go.
How often should packaging sustainability claims be reviewed?
Claims should be reviewed at least annually and whenever materials, suppliers, package design, recovery access, or applicable regulations change. A claim that was supportable in one market or year may become incomplete if collection systems, labelling rules, or supplier documentation change.
