Packaging determines not just how baby corn looks on a retail shelf, but how long it survives the cold chain, what labelling requirements apply in each market, and what MOQ your supplier will accept. Thai exporters offer five primary packaging formats for fresh, chilled and processed baby corn. Choosing correctly at the quotation stage avoids costly re-packing at destination.
Packaging choice fixes shelf life. A loose-carton shipment arriving with 10–12 days from harvest has 4–5 days left after 7 days' sea transit. The same product in a sealed MAP tray arrives with 14–17 days remaining. Match packaging to your transit time before selecting a format.
Format 1: Loose Carton (Bulk Fresh)
The baseline export format. Husked baby corn is placed loose in a waxed cardboard carton lined with a polyethylene bag, typically in 5 kg or 10 kg net-weight packs. The carton is pre-cooled to 4–6 °C before sealing.
- Shelf life: 10–12 days from harvest at 4–6 °C
- Typical pack sizes: 5 kg, 10 kg net
- Minimum order: 1 pallet (approximately 200–400 cartons depending on size)
- Best for: Food service distributors, processors, and buyers with fast-moving inventory
- Not suitable for: Sea freight transit longer than 7 days, retail display without repacking
Format 2: Modified Atmosphere Packaging (MAP) Tray
Baby corn is arranged on a rigid PET or PP tray, sealed with a gas-flushed barrier film. The atmosphere inside the pack is adjusted — typically 5% CO₂ and 95% N₂, or a CO₂/O₂/N₂ blend — to slow respiration and inhibit microbial growth. MAP is the preferred format for premium retail in Japan, Taiwan, South Korea and the EU.
- Shelf life: 18–21 days from packaging at 4–6 °C (versus 10–12 days for loose carton)
- Typical retail pack sizes: 100 g, 200 g, 300 g, 454 g (1 lb)
- Minimum order: 1,000–2,000 retail units per SKU (confirm with supplier)
- Best for: Supermarket retail, premium food service, cross-border e-commerce with overnight cold delivery
- Regulatory note: MAP film must comply with EU Regulation (EC) No 1935/2004 on food contact materials (EU), FDA 21 CFR for US market, or equivalent national standard
MAP adds approximately USD 0.15–0.35 per retail unit in packaging material cost. This is typically recovered within two weeks through lower shrinkage losses and the ability to ship by sea rather than airfreight — a cost saving of USD 2–5 per kg on freight alone.
Format 3: Vacuum Pouch
Baby corn is placed in a multi-layer PA/PE or EVOH/PE pouch, vacuum-sealed to remove residual oxygen. Vacuum packs have a lower up-front equipment cost than MAP lines but provide less protection against compression and physical damage during transit.
- Shelf life: 14–18 days at 4–6 °C
- Typical pack sizes: 200 g, 500 g, 1 kg
- Best for: Wholesale buyers, food service portion packs, products where presentation aesthetics are secondary to shelf life
- Limitation: Cobs may flatten or bruise under vacuum pressure if not pre-graded by diameter; specify minimum cob diameter of 1.0 cm to prevent this
Format 4: Canned Baby Corn
Baby corn is thermally processed (retorted) in tinplate or aluminium cans with brine or water, achieving commercial sterility. Canned baby corn is shelf-stable at ambient temperature and is not subject to cold-chain requirements. It accounts for the largest share of global baby corn trade by volume.
- Shelf life: 3–5 years at ambient temperature
- Standard can sizes: 425 g drained weight (410 ml / A2½ can), 850 g, 2.95 kg catering size
- Minimum order: Typically 1 × 20-foot container (approximately 2,400–3,600 cartons of 12 × 425 g cans)
- Best for: Long-distance markets, ambient-temperature retail, foodservice and industrial processing
- Regulatory note: Canned baby corn falls under HS code 2005.80. Thai exporters must hold a valid Codex-aligned HACCP certificate for canning operations
Format 5: IQF Frozen Baby Corn
Baby corn is blanched, individually quick frozen (IQF) at −35 °C or below, and packed in polypropylene bags within master cartons. IQF maintains individual piece separation, allowing users to portion exact quantities without thawing the full pack.
- Shelf life: 18–24 months at −18 °C or below
- Typical pack sizes: 500 g, 1 kg retail bags; 10 kg bulk bags for food service
- Minimum order: 1 × 20-foot reefer container at −18 °C (approximately 18–20 MT)
- Best for: Industrial buyers, meal-kit producers, food service with frozen menu items, markets with underdeveloped fresh cold-chain infrastructure
- Regulatory note: IQF baby corn HS code is 0710.80. Frozen products exported to the US must comply with FSMA Preventive Controls for Human Food

How to Select the Right Format
- Determine transit time. Air freight under 48 hours: any fresh format works. Sea freight 5–10 days: MAP or vacuum only. Over 10 days or ambient distribution: canned or frozen.
- Confirm end channel. Retail shelf needs MAP or vacuum for appearance and shelf life. Food service can use loose carton. Long-term inventory needs canned or IQF.
- Check destination market labelling rules before finalising artwork — re-labelling at destination is expensive and creates traceability gaps.
- Verify MOQ against your volume. MAP and vacuum have lower MOQs than canned or frozen; loose carton has the lowest entry point for fresh formats.
- Request a pre-shipment sample in your chosen pack format and run a 14-day cold-chain simulation before confirming a commercial order.
