Food grade plastics for processing and packaging lines
Wear components and contact surfaces for high-throughput food, beverage and dairy lines. Grade selection accounts for direct contact status, caustic and acid CIP chemistry, wet abrasion and, where a line requires it, metal detectability and colour contrast for foreign-body control.

Supply chain standards
The standards we require from our supply chain
Food-contact conformity is a property of a specific grade and lot, not of a material family. We require documented conformity from certified manufacturing partners before a grade is offered for contact service.
Certifications listed are held by certified manufacturing partners in our supply chain. Damrix is a distributor and does not hold manufacturing certification.
Sector requirements
What drives grade selection on a food line
The four conditions below govern nearly every food-line failure we are asked to review. Each is answerable before material is committed.
REQ 01
Wet abrasion
Product carry-over, sugars and grit accelerate wear on guide rails and wear strips. UHMW-PE holds the highest abrasion index of any thermoplastic in slurry conditions.
REQ 02
CIP chemistry
Caustic and peracetic cycles at elevated temperature embrittle some grades. Chemical compatibility is confirmed against your actual cleaning concentration and dwell time.
REQ 03
Foreign-body control
Metal-detectable and X-ray visible grades, plus blue contrast colouring, are available in UHMW-PE and acetal for HACCP-controlled zones.
REQ 04
Dimensional stability
Moisture uptake shifts fit on close-tolerance filler and capper parts. Acetal and PET-P are specified where nylon would grow out of tolerance.
Qualifying materials
Grades applied in this sector
Grades below are carried with food-contact documentation available on selected variants. Confirm the specific grade before committing to a contact application — a family flag is not a grade certificate.
- UHMW-PEDMX-EN-201
Highest abrasion resistance of any thermoplastic with very low friction; the default wear material for food conveying and bulk material handling.
FDANSF 513-A DAIRY - POM-C / POM-HDMX-EN-203
The general-purpose precision machining material — tight tolerance hold, low moisture uptake and consistent stiffness.
FDANSF 513-A DAIRY - PTFEDMX-HP-105
Lowest coefficient of friction of any solid material, near-universal chemical inertness and the widest service temperature window we carry.
FDAUSP CLASS VI3-A DAIRY - HDPE / PE-300DMX-EN-202
Cost-effective, weldable food-contact material for tanks, fabricated enclosures and light wear duty.
FDANSF 51NSF 61 - PET-PDMX-EN-205
Higher stiffness and better dimensional stability than acetal, with good wear performance in dry running conditions.
FDANSF 51EU 10/2011 - PCDMX-EN-207
Transparent, high-impact material for machine guarding, sight windows and viewing panels.
FDA (select grades)UL 94 V-2CSA-recognised guarding - PPSDMX-HP-103
Dimensionally stable, chemically inert semi-crystalline material with essentially no known solvents below 200 °C.
FDANSF 51 (select grades)UL 94 V-0 - PP-H / PP-CDMX-EN-206
Acid and base resistant, weldable and low cost; standard for fabricated chemical containment.
FDANSF 51USP CLASS VI (select grades) - PEEKDMX-HP-101
Semi-crystalline high-performance thermoplastic for sustained load at elevated temperature, steam exposure and repeat sterilisation cycles.
FDAUSP CLASS VIEU 10/2011
Documentation
What ships with the material
Documentation is issued against the shipped lot and is intended to drop directly into a HACCP or food-safety file without further chasing.
