Sustainable Packaging Claims: A Practical Brand Guide

Map the disposal pathway before choosing a material

Sustainable packaging decisions often start with material samples. A better first step is a pathway map: for each component, list where it is likely to go in the markets where the item is sold. A fiber carton, a film bag, a label and a closure may have different pathways. The material name alone does not establish an environmental claim. If the pathway is uncertain, treat the claim as unresolved and design artwork that avoids implying a result you cannot document. This is planning, not legal clearance.

• List each component separately, including labels, closures and films.
• Record the market and sales channel for each SKU.
• Note whether collection is available to a substantial majority of consumers where the item is sold.
• Mark any component with an uncertain pathway as pending review.

Build a claims register before artwork

A claims register is a simple table with the exact phrase, component, market, evidence, qualification and owner. It helps keep a phrase on a mockup from becoming an unsupported claim. FTC guidance treats compostable claims made directly or by implication as claims, so we recommend reviewing images, colors and symbols for any environmental benefit they may suggest even without words. Keep evidence current and link it to the specific SKU. If a supplier changes a material, reopen the claim and check whether the old evidence still applies.

• Use exact wording, not shorthand.
• Record the standard, test report or supplier document referenced.
• Record the qualifier that must appear nearby.
• Assign a reviewer for regulatory and food contact questions.

Compostable claims need scientific evidence and clear limits

The Federal Trade Commission says a compostable claim should rest on competent and reliable scientific evidence that all materials become usable compost safely and in approximately the same time as the materials with which they are composted. EPA explains that compostable plastic is generally intended for industrial or commercial composting and that ASTM D6400 and D6868 outline commercial compostability specifications. EPA also states that there are no ASTM standard test methods for evaluating plastic home compostability. FTC guidance calls for clear and prominent qualification where necessary to avoid deception if an item cannot compost safely and in a timely manner at home or if the claim misleads consumers about disposal in a landfill. It also calls for qualification if appropriate municipal or institutional facilities are not available to a substantial majority of consumers or communities where the item is sold. Check whether accessible programs accept the specific item, and review applicable state labeling and certification rules.

• Do not use biodegradable as a synonym for compostable.
• Keep scientific evidence covering every component and any certification required by applicable rules or used to support the claim.
• State the intended disposal environment.
• Assess home compostability and access to appropriate facilities that accept the item before considering an unqualified claim.

Recycled content in food contact needs a safety review

Recycled content is not automatically suitable for food contact. FDA identifies concerns about contaminants, inputs not regulated for food contact and noncompliant adjuvants in recycled plastic. When a manufacturer requests FDA consideration of a proposed use, the agency describes information to submit about the recycling process, source controls, testing and conditions of use. FDA's case-specific advice is informal, not a universal approval requirement; the cited page also identifies certain tertiary recycling processes it no longer evaluates individually. Ask the converter for the specific recycled stream, intended food contact conditions and supporting safety documentation. Do not treat a general recycled content statement as evidence of food contact suitability.

• Identify the recycled material and its source.
• Confirm intended temperature, food type, contact duration and single or repeated use.
• Ask whether the converter has a food contact review for that stream.
• Keep the answer with the SKU file.

Source reduction and EPR data need a paper trail

Source reduction claims should be tied to measured changes, not adjectives. CalRecycle's SB 54 guidance describes statewide source reduction targets for single-use plastic packaging and plastic food service ware. It assigns responsibility for meeting those targets to the producer responsibility organization through its approved plan, rather than requiring each producer to meet the statewide targets alone. Participating producers contribute through plan implementation and reporting. Track baseline mass per unit, material type and the change made. Confirm current applicability, targets, timing and reporting duties with the relevant authority and program; an agreement alone does not establish all legal obligations.

• Keep a baseline for each component.
• Record the change in grams per unit and units sold.
• Separate arithmetic estimates from verified results.
• Do not imply a statewide target is your individual legal duty without confirming.

Worked example: lightweighting and recycled fiber arithmetic

This is a hypothetical, simplified arithmetic exercise, not a validation, measurement or quote. All figures are illustrative. Suppose a brand sells 10,000 units. A hypothetical baseline film bag weighs 6 grams per unit, so the total film mass is 6 grams multiplied by 10,000, which equals 60,000 grams or 60 kilograms. A hypothetical proposed bag weighs 4.5 grams per unit, so the total is 45,000 grams or 45 kilograms. The reduction is 15 kilograms. Divide 15 by 60 to get 0.25, or a 25 percent reduction in film mass for that order.

For a hypothetical fiber carton, suppose each carton weighs 32 grams and the supplier documents that recycled fiber accounts for 30 percent of the complete carton's mass, not merely 30 percent of its fiber fraction. For 10,000 cartons, total carton mass is 32 grams multiplied by 10,000, which equals 320,000 grams or 320 kilograms. Recycled fiber mass is 320 kilograms multiplied by 0.30, which equals 96 kilograms. If the documented percentage instead applies only to the fiber fraction, use that fraction's mass as the calculation base. These figures show arithmetic only; they do not prove recyclability, compostability or food contact suitability. Confirm the percentage denominator and material data with the converter before validating a claim for artwork.

A claim review table for brand teams

Use a table to separate the claim from the evidence and the qualifier. The table is a planning tool, not a legal opinion. The reviewer should be able to see why the claim is supportable for the named market and component.

A practical checklist before artwork release

This checklist is Teal's editorial planning framework. The cited sources cover only specific underlying principles. Adapt the checklist to your own legal and technical review.

• List every component and its likely disposal pathway in each market.
• Write the exact claim and the exact qualifier that will appear.
• Link each claim to evidence for the named SKU and supplier.
• Check compostable claims for scientific substantiation, applicable certification rules, intended environment and access to facilities that accept the item.
• Check recycled content claims for food contact review where relevant.
• Record baseline and revised mass for source reduction statements.
• Review symbols, colors and images for implied claims.
• Confirm state, channel and EPR obligations in your own agreements.
• Keep an approval record before files go to the converter.

Scope limits and what this guide does not decide

This guide does not determine legal compliance, food contact suitability, compostability, recyclability or tax obligations. It does not set safety thresholds, shelf life or temperature limits. It does not replace testing, certification or review by your converter and legal team. State and channel rules change, so confirm current requirements in your own agreements. Where a claim depends on local collection, confirm access in the markets where the item is sold. If evidence is incomplete, hold the claim rather than fill the gap with a softer word that still implies a result.
