What are the best suppliers and sourcing strategies for sustainable packaging options including heat shrink capsules, pouches, paper bottles, and compostable cups?

The community has tested and recommended several specific sustainable packaging suppliers across different formats:

**Heat shrink capsules (biodegradable):** - **Viscose Closures** (viscoseclosures.com/celons-viskrings/) — members are actively moving forward with rebranding using these. Contact via designer for bespoke versions and lead time quotes.

**Eco pouches and bag-in-box formats:** - **Smurfit Kappa** — recommended for 5-litre eco pouches and bag-in-box solutions. Members can provide introductions and key learnings on sourcing. - **baginboxshop.co.uk** — another option for bag-in-box formats.

**Paper bottles:** - **FrugalPac** — the go-to choice for members scaling sustainably. They offer off-the-shelf bottles that are easy to brand (example: the Avallen bottle), avoiding the complications of fully bespoke designs tied to major corporations. Multiple community members work with FrugalPac for filling/production support.

**Compostable cups for festivals and events:** - **Just Peel** (Alison Hobson, 07711 176179, www.justpeel.co.uk / www.cupapeel.co.uk) — pricing around £0.14 per paper pint cup. Tested and trusted by members. - **Branded Cups and Cups Direct** — both used successfully by members ordering 20–50k units at a time with good bulk pricing (targeting around £0.10 per unit). - **Limepack** — biodegradable cups used at 10k+ volumes. Rated for high-strength spirits and hot drinks (though hot-drink performance is limited).

**Key caveats:** Paper bottle suppliers (other than FrugalPac) are often tied to major corporate contracts, making bespoke production difficult and expensive. For compostable cups, pricing improves significantly with larger order volumes (20–50k units). Lead times on bespoke heat shrink capsules should be confirmed directly with suppliers.
