How do paper bottle filling processes work and what are the key challenges and suppliers involved?

Paper bottles (such as Frugal bottles) can be filled on conventional bottling lines, but the process presents significant logistical challenges that most producers cannot handle in-house without specialist support.

**Key supplier and process details:** - **Frugal** — Provides printing, assembly, and pouches in the UK. Their bottles come with full 360° label coverage. MOQ is 5,000 units (much cheaper and easier at 20k+). Material cost is approximately £1 per bottle, plus roughly £1 per bottle for filling. - **Silent Pool** — Experienced bottler offering filling services for paper bottles; members recommend contacting them directly for filling pricing and general information.

**Critical challenges members highlighted:** - Filling is "a nightmare" and "FILLING hell" — most producers lack the right equipment due to pouch vacuum requirements and the need to weight bottles accurately. - **Do not attempt to fill yourself.** Members reported losing 6 months to failed in-house attempts. - Long lead times and frequent delays are normal. - Frugal's business model focuses on selling assembly machines rather than finished goods, which complicates access to bottling capacity and has driven up pricing. - Frugal is actively working to onboard more bottlers, but capacity remains constrained.

**Retail and trade reception:** - No pushback from buyers or consumers; retailers and on-trade actually respond well once the sustainability story is explained. Some resistance to the plastic bag and cap, but sustainability is not a zero-sum equation. - Best practice: paper bottles for off-trade and e-commerce (low carbon, low breakage risk); bulk solutions or ecoSpirits alternatives for on-trade.
