Why Buy Direct From a UK Manufacturer?

  • Tailored Film Thicknesses: We stock standard 40-micron (40mic) and heavy-duty 50-micron (50mic) weights. Thicker microns offer high melting points and superior puncture resistance to ensure your food products don't tear during transit.
  • The "Crimp" Advantage: Our bags utilize a textured, heat-bonded bottom weld. This creates a completely airtight, moisture-resistant barrier that maximizes product shelf life and offers tamper-evidence.
  • 100% Certified Food-Grade: All of our clear poly bags are manufactured from virgin, food-safe polymer, completely resistant to mold, rot, and grease.
  • Bespoke Printing & Scaling: Need your logo on the film? We offer in-house flexographic and gravure printing. For custom runs or bulk wholesale orders over 25,000 units, contact our team directly.
