Kitchenware and food storage: polymer sourcing guide

Reusable food containers, mixing bowls, measuring jugs, and chopping boards. Food contact compliance and dishwasher resistance are non-negotiable.

Key requirements

• EU 10/2011 food-contact compliance with grade-specific Declaration of Compliance
• Dishwasher cycle resistance to 90 °C with no warpage
• Microwave compatibility for PP grades; opaque only for HDPE
• Optical clarity for clear food storage (clarified random copolymer PP)

Procurement notes

Clarified random copolymer PP — typically nucleated with Milliken Millad NX8000 or equivalent — dominates clear food storage. Specific grades like Borealis BH345MO or LyondellBasell Hostalen ACP are widely qualified at major converters. HDPE blow grade covers opaque containers and lids. Microwave-safe claims need PP exclusively (HDPE deforms at 130 °C). Major retail brands (Tupperware, IKEA 365+, Sistema) work direct with producers; private-label OEMs source through compounders.
