A plastic ice tray manufacturer moulds the freezer staples that kitchen brands, supermarkets and promotional buyers order in five-figure quantities. The modern category is built on ice cube tray pp bodies with TPE bases, stackable footprints and lids that keep ice clean and odour-free. This guide covers the range, the compliance points and the details worth fixing before production.
Product range and formats
- Classic trays with 14 to 36 cavities for standard home freezers.
- Stackable ice tray sets that nest vertically to double or triple freezer capacity.
- Ice tray with lid models that block spills and stop cubes absorbing freezer odours.
- Novelty shapes such as spheres, diamonds, rings and character moulds for gifting and bars.
- Multi-part kits with storage bins, scoops and lid lifters bundled for retail.
Materials and food-contact compliance
Production trays pair a food-grade PP frame with a TPE or silicone base: PP holds the shape and survives commercial dishwashers, while the flexible base twists to release cubes without a knife. Both resins are BPA-free, low-odour and rated for freezer service well below -20 degrees C. EU programmes expect a declaration under the framework food-contact regulation, US retail looks for FDA-listed materials, and LFGB is the German-market reference. Resin background sits in our food grade PP compliance guide, and the framework rules are summarised in FDA food contact basics.
Design details that decide reviews
Three details separate trays that sell from trays that get returned. Release is first: the base must flex enough to pop a full tray of cubes after one twist, and cavity walls need a slight draft so ice does not key in. Second is the lid: a spill-resistant cover with two lifter tabs keeps water from freezing across the stack, and lid clearance must suit cube height plus expansion. Third is stacking geometry, where ribs or feet index the next tray without sticking. Cavity counts from 14 to 48 change cube size and freeze time, so match the count to the intended freezer rather than copying a competitor.
Branding, colour and packing
Decoration is usually pad printing, in-mould labels or heat transfer on the lid; bodies take Pantone-matched colours at modest premiums. Sets consolidate well in colour boxes, and 100-300 pieces per carton keeps freight dense. Samples run 7-10 days and bulk production 25-35 days after approval.
What to confirm with a plastic ice tray manufacturer
- Release test: a full tray released after one twist, run on a production sample.
- Freeze and wash validation: a stated cycle count at commercial dishwasher temperatures.
- Food-contact documents: resin declarations covering body, base, lid and pigments.
- Stack stability: indexed feet or ribs so loaded trays do not bond in the freezer.
