Polymer sourcing for yogurt and dairy pots
Thermoformed or injection-moulded tubs for yogurt, cream, and dessert. Thin-wall PP dominates at sub-0.5 mm; HIPS for white opaque body with PP lid.
Recommended polymers
Polypropylene
PPVersatile commodity polyolefin. Highest European production volume after PE. Homopolymer, random and impact copolymer grades cover injection, extrusion, fiber, film.
High-Impact Polystyrene
HIPSPolystyrene toughened with polybutadiene rubber. Sheet thermoforming, appliance liners, dairy packaging.
Key requirements
- EU 10/2011 food-contact compliance with grade-specific Declaration of Compliance
- Wall thickness ≤ 0.4 mm with ≤ ±5% variation across thermoformed web
- Hot-fill resistance to 85 °C without deformation
- Peelable lidding adhesion of 8–15 N per EN 15171
Procurement notes
PP homopolymer (MFI 10–20) in sheet extrusion grade is the workhorse for clear-lidded dairy pots; HIPS thermoform sheet handles opaque white body tubs. Borealis, LyondellBasell and INEOS Styrolution supply the dominant grades. Volume converters (Faerch, Huhtamaki, Greiner Packaging) run annual contracts at 500–2,000 t per line; smaller dairies typically source via Resinex or Kloeckner Plastics distributor stock.
