What Packaging Do Restaurants Use for Wholesale Produce Sales? The 9 Formats, Grades, and Cold-Chain Requirements That Actually Ship

Restaurant wholesale produce moves in a set packaging stack. Waxed corrugated (RSC) boxes hold wet produce like greens, berries, cut veg, and melons. Unwaxed bulk cartons hold root crops and winter squash.

Returnable plastic containers (RPCs) hold fast-moving items for big-box buyers. Foam coolers with gel packs hold cold-sensitive loads for last-mile drops. Plastic bulk bins (280–2,000 lb) hold case-lot and processor orders.

Pack-count is set by crop. Lettuce ships 24-head. Strawberries ship 12×1-lb clamshell. Cherry tomatoes ship 12×1-pint. Every case must carry PACA labels. Most mid-size and up buyers also need a PTI case code for tracking.

This guide walks through the 9 produce packaging formats used in US foodservice. You will see cold-chain needs by crop class, the PACA and PTI rules floor, and the cost trade-offs for direct-source produce programs. Packaging Vista supplies custom food-service corrugated and bulk corrugated. We also stock food-grade packaging for US restaurant and distributor accounts.

1. Waxed corrugated RSC produce boxes.

The top wholesale produce format. RSC corrugated boxes with wax or a wax-swap coating guard against damp-driven strength loss. A plain corrugated box loses 30–50% of its edge-crush test (ECT) score when wet. Waxed corrugated holds its score across the cold chain (85–95% RH in produce coolers). Common sizes and uses:

• Standard produce case: 20 × 13 × 10 inch, ECT 32–44, 25–40 lb capacity. Used for lettuce (24-head), broccoli (18-count), celery (24-count), cauliflower.
• Half case: 20 × 13 × 5 inch. Berries, cut melon, cut veg.
• Narrow deep case: 24 × 12 × 12 inch. Cucumbers, zucchini, specialty peppers.
• Flat (lug) box: 24 × 16 × 4 inch. Soft tree fruit (peaches, plums), tomatoes.

Wax type drives whether you can recycle the box. Classic oil-wax corrugated is not fit for curbside paper streams. Wax-swap coatings (poly-coated or water-based barriers) keep damp out but still recycle. Green-minded restaurants want them more each year.

2. Unwaxed corrugated bulk cartons (dry produce).

Good for crops that don't sweat. Potatoes, onions, winter squash, hard-rind melons, apples (CA storage), ginger, and cured garlic ship fine in plain corrugated. The per-case cost is lower. Boxes recycle at the curb. ECT needs stay low too (28–32 is normal). Common formats:

• 50 lb potato box: 20 × 15 × 8 inch.
• 40 lb apple box: traditional tray-pack lug.
• 35 lb onion sack carrier: half-slotted container for mesh bag transport.
• 45 lb winter squash case: single-wall, ventilated.

3. Returnable plastic containers (RPCs).

Reusable, washable, stackable, foldable PP crates run by pool firms (IFCO, Polymer Logistics, Tosca). The pool owner washes, sanitizes, and sends the crate out again after each trip.

They rule at Walmart, Costco, Whole Foods, Sam's Club, Kroger, Target, and more foodservice depots each year. Pros: lower per-trip cost at scale, no packaging trash at the dock, tougher than corrugated.

Cons: higher capex (crate deposit), you need reverse logistics, and set sizes cap custom pack layouts. Common sizes:

• IFCO 6411: 23.6 × 15.7 × 4.3 inch — soft fruit, cherry tomatoes, berries.
• IFCO 6420: 23.6 × 15.7 × 7.9 inch — most produce.
• IFCO 6425: 23.6 × 15.7 × 9.8 inch — broccoli, cauliflower, leafy greens.
• Tosca various: similar footprints, nested-fold design for empty return.

4. Clamshells and PET punnets.

Berries, mushrooms, cut fruit, cherry tomatoes, grapes, and some microgreens ship in single-serve clamshells (PET) inside a master case. Standard sizes: 1 pint (473 ml), 1 lb (454 g), 2 lb, 3 lb.

The master case can be waxed corrugated or an RPC. Clamshells shield soft produce from crush damage. They also let the kitchen count portions with no extra repacking. The trade-off: one-use plastic is now a green pain point.

Some buyers now ask for rPET or compostable PLA swaps.

5. Bulk bins and combo bins.

Big accounts move produce in bulk bins or combo bins. That means processors, central commissaries, and chain-restaurant commissaries. These are corrugated or plastic tubs holding 280 lb (small combo) up to 2,000 lb (full bulk bin).

The standard footprint is 48 × 40 inch (pallet-size) at 24–48 inch tall. Common uses: tomatoes (processors), potatoes (chip and fry makers), apples (juice and sauce), onions, and carrots.

Restaurants rarely see bulk bins unless they run a commissary. The use is upstream.

6. Mesh and poly bags.

Onions, potatoes, citrus, and some brassicas ship in woven PP mesh bags (10 lb, 25 lb, 50 lb) or thin poly bags (5 lb, 10 lb) inside a master carton or on a pallet. Mesh lets air flow (key for curing onions and potatoes). Poly bags lock in damp (good for cut citrus and carrot sticks). The master carton sets the transit base. The inner bags set the kitchen portion.

7. Insulated containers and cold packs.

Some kitchens can't take produce at room temp. Small spots lack a dock fridge. For those drops, produce ships in insulated boxes. Options include foam coolers (EPS or EPP), lined corrugated hybrids, or rPET cold shippers. Gel packs or dry ice go inside. The cold-chain targets by crop:

8. Wet-lock corrugated and liquid-tight cases.

Some produce ships in brine, water-pack, or ice slurry. Think specialty mushrooms, water-packed asparagus, and iced sides like lemon wedges. For these, wet-lock corrugated or triple-wall liquid-tight cases stop the carton from caving in under steady damp. These cost more than plain waxed RSC. But the other option (plastic tub inside corrugated) is heavier and less green.

9. Specialty mushroom and herb packaging.

Pricey, wet items like specialty mushrooms (shiitake, oyster, maitake, enoki) and fresh herbs ship in vented half-pint or pint clamshells inside a waxed master case. Some ship in damp-controlled EMAP films. Thin margins and short shelf life justify these top-tier packs. They add 2–4 days of shelf life at the kitchen.

PACA labels and PTI case codes: the rules floor.

Every wholesale produce case shipped across US state lines carries two label layers:

PACA labels (Perishable Agricultural Commodities Act).

The USDA PACA rules say the case must show:

• Packer or shipper name and address (or valid USDA packer code).
• Country of origin.
• Crop name and variety.
• Grade (if claimed).
• Net weight (not just case count).
• Lot or pack code (for traceback).

USDA enforces PACA on complaint and spot-audit. Shippers who skip the rules lose dock acceptance and risk PACA license action.

PTI case codes (Produce Traceability Initiative).

The PTI is an opt-in trade standard. But it is now a must for most mid-size and up buyers. It calls for a GS1-128 barcode on every case that holds:

• GTIN (Global Trade Item Number) — spots the brand+product+pack size.
• Lot code — batch tag.
• Pack date — day the case was packed.

PTI lets you trace one step back and one step forward in hours. That is the speed the FDA FSMA trace rule now wants. Chain restaurants, foodservice depots (Sysco, US Foods, PFG), and shops all need PTI codes at the case level.

Who sources what packaging in a restaurant program.

Most restaurants don't spec their own produce packs. The supplier picks the format, and the kitchen gets what the supplier sends. But if you run a direct-source program (buying from a farm, a farmers' market, a specialty grower, or your own commissary), you pick the case format. The sourcing patterns:

• Restaurant buying from Sysco / US Foods / PFG: gets what the depot sends (RPCs on fast movers, waxed corrugated on the rest, bulk bins never).
• Restaurant buying direct from a farm: the farm packs in waxed RSC or returnable crates. The kitchen sets pack-count and sometimes owns the crates.
• Restaurant with its own commissary: buys bulk bins or combo bins, then repacks into kitchen portions.
• Restaurant with a farmers-market or CSA program: uses waxed corrugated half-cases, open-top lugs, or wood crates. Branded for the shop.

Frequently asked questions.

Why is produce packaging waxed?

Plain corrugated loses 30–50% of its edge-crush score when wet. Produce coolers run at 85–95% damp air. Wax or wax-swap coatings keep the carton sound across the cold chain. Only dry crops (potatoes, onions, winter squash, cured garlic) can safely ship in plain corrugated.

Are RPCs needed for wholesale produce?

Not by law, but by big buyers. Walmart, Costco, Whole Foods, Sam's Club, Kroger, Target, and some foodservice depots need RPCs for set fast-moving SKUs. Smaller indie restaurants and niche depots still take waxed corrugated by default.

What is PACA and does it apply to small farmers selling to restaurants?

PACA is the USDA law for produce sales across state lines. Growers who sell less than $230,000 of produce a year are usually free from PACA license needs. But they still must follow basic label rules. Restaurants buying from PACA-licensed shippers get PACA dispute cover. Buying from unlicensed shippers drops that cover.

Is PTI mandatory?

Not by federal law. But it is a must in practice for anyone selling to a mid-size or bigger buyer. Big foodservice depots (Sysco, US Foods, PFG), chain restaurants, and shops all need PTI case codes. Small direct-to-restaurant farm sales are usually free from it.

What's the cheapest wholesale produce case?

Plain single-wall corrugated for dry crops runs $0.60–$1.20 per case at pallet counts. Waxed corrugated for wet crops is $1.20–$3.00 per case. RPCs are more or less free per case for the buyer (deposit-based). But $8–$20 of locked-in cash sits in each crate across the pool. Bulk bins run $20–$60 one-way or deposit-based returnable.

Can produce ship in regular (non-waxed) cardboard boxes?

Only dry crops. Potatoes, onions, winter squash, cured garlic, apples (CA storage), ginger, hard-rind melons: yes. Anything with damp skin (greens, berries, tomatoes, cucumbers, cut veg, mushrooms, soft fruit): no. The carton will cave in within one or two cold-chain cycles.

How do I design a custom branded produce case?

Spec waxed or wax-swap RSC corrugated at the right ECT (32–44 for most crops). The dieline should match the set pack-count for your crop. Flexo print 1–4 colors on the outer liner.

Add the PACA must-have text (packer, origin, variety, grade, net weight, lot code). Save a GS1-128 barcode zone for PTI. Our corrugated boxes page covers the build options. Our food &

beverage boxes page covers the food-grade spec layer.

What's the pack-count convention for common restaurant produce?

Lettuce: 24-head case. Romaine hearts: 12 x 3-pack. Strawberries: 12 x 1-lb clamshell flat (8 flats per master). Blueberries: 12 x 1-pint flat. Cherry tomatoes: 12 x 1-pint flat. Mushrooms (white, cremini): 10-lb bulk box.

Portabella: 5-lb case. Specialty mushrooms: 3-lb case. Bananas: 40-lb case. Apples: 40-lb case (tray-packed by count 72/80/88/100/125/138). Lemons/limes: 40-lb case (count varies).

Avocados: 25-lb case (count 36/48/60/70/84).

Do restaurants pay for the produce packaging separately?

No. Packaging is baked into the per-case price in all standard depot models. The one swap is RPC programs. There, the kitchen pays a per-crate deposit that comes back on return. Direct-from-farm programs may list packaging on the invoice. Most don't.

What's the biggest produce packaging mistake?

Three ties: shipping wet produce in plain corrugated (carton caves mid-chain). Missing or wrong PACA case marks (dock turns it away). And no PTI case code at a mid-size or bigger buyer (invoice chargeback or load refusal). Each is easy to dodge with a one-page spec sheet before the first run.

The bottom line.

Restaurant wholesale produce packaging is a set stack. Waxed corrugated RSC boxes for wet crops. Plain corrugated for dry. RPCs at big-box buyers. Bulk bins for processors. Foam-plus-gel coolers for last-mile cold-chain.

Mesh and poly bags for curing crops. Clamshells for soft fruit. And niche formats for mushrooms, herbs, and wet-pack produce. Pack-counts are set by crop. PACA labels are a must. PTI case codes are a must at every mid-size and bigger buyer.

Cold-chain temp targets are crop-specific. Done right, the stack gives you 5–14 days of kitchen shelf life, zero chargebacks, and clean dock takes.
