Packaging is hard to correct. Once the run is printed, removing a weak claim means reprinting everything. Alios reads the pack first as a shopper, then as a lawyer, and flags what could not be justified.
Space is tight on a pack, so wording gets shortened. That is exactly where a claim becomes impossible to verify.
Recyclable means nothing without an actual collection stream in the country of sale, and without saying which part of the pack is covered. Biodegradable and compostable assume precise conditions, rarely those of a household bin.
A green pictogram, a stylised leaf or a label the brand created itself all look like independent certification. The European directive bans displaying a sustainability label based on self-certification alone.
Natural materials, responsibly sourced, up to 80% recycled. The tool flags wording with a vague scope, claims that cover a minor part of the product, and figures stated with no basis of calculation.
