Rotomolded Food Carrier 90L Insulated Delivery Box GN Pan Storage Four Casters PE Cabinet 635x460x640mm

This rotomolded food carrier is the version of the 90L insulated cabinet for buyers who care how it is made, not only what it holds. The body, door frame, pan chutes, handle bosses and caster mounts are formed in one rotational moulding cycle, producing a stress-free seamless double-wall shell with uniform thickness and no weld line. The cavity between the walls is then filled with high-density polyurethane foam, which is the layer that actually does the thermal work: it holds hot pans above 60 C and chilled product below 5 C for up to six hours without any electrical supply.

Rotational moulding matters in this application because the failure modes of the alternative, a metal cabinet or a thermoformed liner in a frame, are exactly the failure modes that kill insulated boxes in service: rust at the seams, impact cracks at the corners, delamination of the liner and cold bridging through fixings. A rotomolded LLDPE shell has no seams, no fixings through the insulation and no metal to corrode, so its thermal and structural performance does not degrade with wash-down cycles. That is why the format has become standard equipment in hospital kitchens, ship galleys, food factories and military field kitchens, and why it survives years of daily loading bay abuse.

• Single-Cycle Rotomolded Body: Shell, chutes, handle bosses and caster mounts are moulded in one cycle, giving uniform wall thickness and a seamless structure with no welded joint to fatigue.
• PU Foam Core, Not Air: The 30 mm high-density polyurethane core is the thermal engine of the carrier, holding above 60 C for hot food and below 5 C for chilled food for up to six hours.
• No Corrosion Path: No metal frame, no rivets through the insulation and no liner to delaminate, so wash-down, steam and sanitizer do not shorten the working life of the cabinet.
• Impact-Tolerant Corners: LLDPE flexes and recovers where metal dents and gelcoat cracks, which is what keeps the box serviceable after years of tailgate loading and stacking.
• Standard GN Pan System: Five 65 mm full-size GN pans or ten half-size pans slot into moulded chutes, so the carrier integrates with existing kitchen pans and existing plating lines.
• Replaceable Service Parts: Door gasket, nylon latches, vent cap and casters are user-replaceable items held as spares, so a five year old carrier can be returned to full performance instead of scrapped.

Typical applications include hospital and care-home meal distribution, ship and offshore galley service, food factory batch transfer between processing rooms, military and field kitchen provisioning, airline and rail catering, school dining halls, plus routine catering and event work. The rotomolded carrier is also used where hygiene audits are strict, because the smooth seamless interior can be fully washed and inspected, and where equipment is expected to remain in service for eight to ten years rather than being replaced every two seasons.

Each carrier ships one piece per PE bag with corner protection in a five-layer carton of 645 x 465 x 645 mm at 17 kg gross, roughly 110 pieces per 20GP or 270 pieces per 40HQ, with mixed loading of other insulated models available to optimise freight. SHANGHAI TOPGREEN INDUSTRIAL CO., LTD operates its own rotational moulding plant, including mould design and fabrication, so non-standard sizes, additional pan chutes, deeper cavities, custom colours and embossed branding are engineering changes rather than outsourced projects. Inspection covers wall thickness at four points, foam density, a latch cycle test, a loaded caster roll test, a logged temperature hold test and a packed carton drop test, with a batch report available on request. The carrier carries a twelve month warranty on shell, hardware and casters, spare gaskets, latches, vents and wheels are stocked, and pre-production samples can be supplied for field trials before a bulk order is confirmed.
