Sustainable Packaging: What's Actually Changing in 2026

Sustainability requirements are moving from "nice to have" to a baseline expectation from retailers and regulators alike. A few practical shifts worth planning for this year:

Recycled content is becoming a spec, not a marketing line

More buyers are asking for a minimum percentage of PCR (post-consumer recycled) content in PET and HDPE bottles, not just recyclability. Confirm early whether your supplier can certify PCR content on your production run.

Lightweighting without losing strength

Bottle walls have been getting thinner for years, cutting both material use and shipping weight — but there's a floor where a lighter bottle risks denting or cracking. We test wall thickness against your actual fill and transport conditions.

Mono-material design for easier recycling

Caps, labels, and bottles made from a single plastic family (rather than mixed materials) are far easier to recycle at scale. Where possible, we recommend matching your closure material to your bottle material.

None of this needs to mean a full redesign — often it's a case of swapping in an equivalent stock item with a lower environmental footprint. Ask us for the options available in your current bottle range.
