A square paper bowl earns its place in a takeaway line for one reason: it uses the width of a bag or a delivery tray that a round bowl wastes. KaiLai builds this one in six sizes from 500ml to 1400ml, all on square footprints — the 500ml and 650ml share a 130 × 130mm top, the 750ml through 1400ml share a 170 × 170mm top, so one lid size and one shelf plan serve three volumes each. Board is 250-350GSM food-grade white, kraft or bamboo paper, with PE, PLA, Bio-PBS or water-based coating, printed flexo or offset up to 7 colours. PP, PET and PLA lids are available, and carton load runs 1,311 cartons per 40HQ at 500ml down to 663 at 1400ml. MOQ 50,000pcs.

Round bowls are specified by habit, and they waste space in every step of the chain — in the bag, on the delivery tray, in the carton. A square bowl keeps the same volume in a footprint that nests against the next one, which is why salad, poke and grain-bowl operators move to square once volume passes a few hundred covers a day. KaiLai supplies these bowls to restaurants, delis and food distributors in 60+ countries, backed by 24 years of manufacturing and BRC Grade A — the certifications that decide whether a supermarket buyer will list the pack at all.

The range is built in two footprints rather than six unrelated moulds. SC-500ML and SC-650ML share a 130 × 130mm top and differ only in depth, 47mm against 60mm. SC-750ML, SC-1000ML, SC-1200ML and SC-1400ML share a 170 × 170mm top at 45, 55, 65 and 75mm deep. In practice that means two lid diameters and two shelf positions cover the entire menu, and a kitchen can move a dish from a side to a main without re-planning its packaging.

Two footprints, six volumes — 130mm and 170mm tops
Barrier is the second decision, because a salad bowl holds dressing and a grain bowl holds oil. PE lamination is the standard and the cheapest; PLA lining and Bio-PBS coating are the compostable routes; water-based coating is the option for buyers who want a repulpable bowl and can accept a shorter hold time on very wet dressings. Board weight runs 250-350GSM, and the higher end is what keeps a 1400ml bowl from flexing when it is lifted full. Lids are PP, PET or PLA — PET for a clear lid that shows the bowl contents, PP where a hot or heavily sauced dish is involved.

Two footprints, six volumes — 130mm top for 500/650ml, 170mm top for 750/1000/1200/1400ml, so two lid sizes cover the whole menu.
Square footprint saves bag and tray space — the reason salad, poke and grain-bowl operators specify square over round.
Four barrier options — PE, PLA, Bio-PBS and water-based coating on 250-350GSM food-grade board, for dressing and oil-heavy dishes.
PP / PET / PLA lids — clear PET for a visible bowl, PP for hot or heavily sauced contents.
