Nellie's
Nellie's leans natural - plant-based powders in reusable tins - and its dishwasher powder is PVA-free simply by being a loose powder rather than a film-wrapped pod. Two honest caveats keep it from being absolute: the tin usually ships with the powder in a plastic bag plus a plastic scoop, and the brand also sells plastic dryer balls elsewhere in its range. For the dishwasher powder specifically, the format is genuinely film-free.

Publishes ingredient lists and the tin packaging, but is less upfront that the tin's initial fill comes in a plastic bag.
