Quality & Compliance

Our No-Compromise Standard

Precision engineering meets rigorous hygiene. We operate with a compliance-first mindset while working toward formal industry certifications.

At The Filling Lab, we prioritise hygiene, safety and compliance. Our Bolton facility is built around pharmaceutical-grade segregation, Mechanical Hygiene and Total Batch Traceability - So your supply chain has the paper trail it needs.

Pillar 1

Mechanical Hygiene & Sanitisation

We do not rely on simple rinse-through cleaning. Between every production run we implement a strict mechanical strip-down protocol.

  • Full Disassembly: pistons, nozzles and tubing are physically removed and deep-cleaned.
  • 316 food-grade stainless steel on all product contact points, ensuring zero reaction with acidic foods or volatile chemicals.
  • Dedicated lines with strict segregation between food-grade, fragrance and industrial zones to eliminate cross-contamination risk.

Pillar 2

Total Batch Traceability

In a professional supply chain, data is as important as the liquid itself. We provide a full paper trail for every unit that leaves our facility.

  • CIJ Inkjet Coding: every bottle carries permanent batch/lot numbers and expiry or best-before dates.
  • Production logs record ambient temperature, fill-weight checks and operator signatures for every run.
  • Retention Sampling: a master sample from each batch is stored for 12 months - Physical evidence if a query arises later.

Pillar 3

Accuracy & Weight Verification

We eliminate product give-away and ensure you stay legally compliant on every release.

  • Volumetric piston filling calibrated to ±0.5% fill accuracy so a 250g jar is 250g every time.
  • In-line manual weight checks every 30 minutes during a run.
  • Peristaltic and pneumatic flow control minimises aeration so bottles are filled with product, not air.

Technical Partnerships & Compliance

We act as the technical bridge between your formulation and the retail shelf.

  • Medical-grade silicone tubing and food-safe lubricants throughout our machinery.
  • Open-door policy for contract clients - Visit our Bolton unit to review cleaning logs and setup before your first run.
  • We assist with samples required for independent CPSR (cosmetics) or shelf-life (food) testing.
