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 surprisingly standardized packaging stack: waxed corrugated regular-slotted-container (RSC) boxes for high-moisture produce (greens, berries, cut vegetables, melons), unwaxed bulk cartons for root vegetables and winter squash, returnable plastic containers (RPCs) for high-velocity items from big-box receivers, foam coolers plus gel packs for last-mile cold-sensitive deliveries, and plastic bulk bins (280–2,000 lb) for case-lot and processor orders.

Pack-count is standardized by commodity (lettuce 24-head, strawberries 12×1-lb clamshell, cherry tomatoes 12×1-pint), and every case must carry PACA labeling plus (for most mid-size and up receivers) a PTI case code for traceability.

This guide walks through the 9 wholesale produce packaging formats actually used in US foodservice, the cold-chain requirements by product class, the PACA and PTI compliance surface, and the cost-and-use trade-offs for restaurants running direct-source produce programs.

Packaging Vista supplies custom food-service corrugated, bulk corrugated, and food-grade packaging for US restaurant and distributor accounts.

1. Waxed corrugated RSC produce boxes

The dominant wholesale produce format. Regular-slotted-container (RSC) corrugated boxes with a wax impregnation or wax-alternative coating protect against moisture-induced strength loss. A standard unwaxed corrugated box loses 30–50% of its edge-crush test (ECT) rating when wet; waxed corrugated holds its rating across typical cold-chain humidity (85–95% RH in produce coolers).

Common dimensions 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 matters for recyclability: traditional petroleum-wax corrugated is not recyclable in curbside paper streams; wax-alternative coatings (poly-coated or newer repulpable water-based barriers) retain moisture resistance while remaining recyclable — a growing preference among sustainability-minded restaurants.

2. Unwaxed corrugated bulk cartons (dry produce)

For produce that doesn’t sweat — potatoes, onions, winter squash, hard rind melons, apples (controlled-atmosphere storage), ginger, cured garlic — unwaxed corrugated is the standard. Lower per-case cost, fully curbside recyclable, lower ECT required (28–32 is typical). 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 polypropylene crates run by pool operators (IFCO, Polymer Logistics, Tosca). The container owner washes, sanitizes, and redeploys the crate after each trip. Dominant at Walmart, Costco, Whole Foods, Sam’s Club, Kroger, Target, and increasingly in regional foodservice distribution.

Advantages: lower per-trip packaging cost at high volume, zero packaging waste at receiving, structurally more protective than corrugated. Disadvantages: higher capex (deposit per crate), requires reverse logistics, standard sizes limit custom pack configurations.

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

For berries, mushrooms, cut fruit, cherry tomatoes, grapes, and some microgreens, individual-portion clamshells (polyethylene terephthalate, PET) ship 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 preserve soft produce from compression damage and enable restaurant portion-counting without additional repacking. Trade-off: single-use plastic has become a sustainability pain point, with some foodservice buyers now specifying rPET (recycled PET) or compostable PLA alternatives.

5. Bulk bins and combo bins

For large-volume accounts (processors, central commissaries, chain-restaurant commissaries), produce ships in bulk bins or combo bins — corrugated or plastic tubs holding 280 lb (small combo) to 2,000 lb (full bulk bin). Standard footprints are 48 × 40 inch (pallet-footprint) at 24–48 inch height.

Common uses: tomatoes (processors), potatoes (chip and fry producers), apples (juice and sauce), onions, carrots. Restaurants typically don’t receive bulk bins unless they’re operating a commissary; the usage is upstream.

6. Mesh and poly bags

Onions, potatoes, citrus, and some brassicas ship in woven polypropylene mesh bags (10 lb, 25 lb, 50 lb) or extruded poly bags (5 lb, 10 lb) inside a master carton or on a pallet. Mesh maintains airflow (critical for curing onions and potatoes); poly bags lock in moisture (useful for cut citrus and carrot sticks).

The master carton standardizes transit; the inner bags standardize restaurant portions.

7. Insulated containers and cold packs

For last-mile delivery to restaurants that can’t receive at ambient (small operators without a dedicated loading dock refrigerator), produce ships in insulated containers — foam coolers (EPS or EPP), insulated liner-in-corrugated hybrids, or (increasingly) rPET-based cold shippers — with gel packs or dry ice. The cold-chain targets by product:

8. Wet-lock corrugated and liquid-tight cases

For produce in brine, water-pack, or ice-slurry (specialty mushrooms, water-packed asparagus, iced seafood accompaniments like lemon wedges), wet-lock corrugated or triple-wall liquid-tight cases prevent carton collapse under constant moisture. Costlier than standard waxed RSC, but the alternative (plastic tub-in-corrugated) is heavier and less sustainable.

9. Specialty mushroom and herb packaging

High-value, high-moisture items like specialty mushrooms (shiitake, oyster, maitake, enoki) and fresh herbs ship in vented half-pint or pint clamshells inside a waxed master case, or in moisture-controlled Equipment Modified Atmosphere Packaging (EMAP) films. The thin margins and perishability justify premium formats that extend restaurant shelf life by 2–4 days.

PACA labeling and PTI case codes: the compliance floor

Every wholesale produce case shipped in US interstate commerce carries two layers of labeling:

PACA labeling (Perishable Agricultural Commodities Act)

The USDA PACA framework requires produce containers to identify:

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

PACA is enforced on complaint and spot-audit; non-compliant shippers lose receiving-end acceptance and risk PACA license actions.

PTI case codes (Produce Traceability Initiative)

The PTI is a voluntary industry standard, but is now effectively mandatory for most mid-size and above receivers. It specifies a GS1-128 barcode on every case encoding:

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

PTI enables one-step-forward / one-step-back traceability within hours in a contamination event — the kind of speed the FDA Food Safety Modernization Act (FSMA) traceability final rule now expects. Restaurant chains, foodservice distributors (Sysco, US Foods, PFG), and retailers all require PTI compliance at the case level.

Who actually sources what packaging in a restaurant program

Restaurants typically don’t spec their own produce packaging — the supplier does, and the restaurant receives what the supplier chooses. But if the restaurant is running a direct-source program (buying from a farm, farmers’ market, specialty grower, or operating their own commissary), they’re the one specifying the case format. The sourcing patterns:

• Restaurant buying from Sysco / US Foods / PFG: gets whatever the distributor sends (RPCs on high-velocity, waxed corrugated on everything else, bulk bins never).
• Restaurant buying direct from a farm: the farm packs in waxed RSC or returnable crates; the restaurant specifies pack-count and (sometimes) owns the crates.
• Restaurant with its own commissary: buys bulk bins or combo bins, then repackages into kitchen-ready portions.
• Restaurant with a farmers-market or CSA program: uses waxed corrugated half-cases, open-top lugs, or wooden crates; branded for the restaurant.

Frequently asked questions

Why is produce packaging waxed?

Because standard corrugated loses 30–50% of its edge-crush rating when wet, and produce coolers run at 85–95% humidity. Wax impregnation or wax-alternative coatings keep the carton structurally sound across the cold chain. Only dry produce (potatoes, onions, winter squash, cured garlic) can safely ship in unwaxed corrugated.

Are RPCs required for wholesale produce?

Not by law, but by major receivers. Walmart, Costco, Whole Foods, Sam’s Club, Kroger, Target, and some foodservice distributors require RPCs for specific high-velocity SKUs. Smaller independent restaurants and specialty distributors still accept waxed corrugated by default.

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

PACA is the USDA regulatory framework for interstate produce commerce. Growers selling less than $230,000 of produce annually are generally exempt from PACA license requirements but still must comply with basic labeling conventions. Restaurants buying from PACA-licensed shippers are protected under PACA dispute resolution; buying from unlicensed shippers removes that recourse.

Is PTI mandatory?

Not by federal law, but functionally mandatory for anyone selling into a mid-size or larger receiver. All major foodservice distributors (Sysco, US Foods, PFG), chain restaurants, and retailers require PTI case coding. Direct-to-restaurant small-farm sales are usually exempt in practice.

What's the cheapest wholesale produce case?

Unwaxed single-wall corrugated for dry produce runs $0.60–$1.20 per case at pallet quantities. Waxed corrugated for high-moisture is $1.20–$3.00 per case. RPCs are effectively free per case for the receiver (deposit-based), but $8–$20 of embedded capital per 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 produce. Potatoes, onions, winter squash, cured garlic, apples (controlled-atmosphere), ginger, hard-rind melons: yes. Everything with surface moisture (greens, berries, tomatoes, cucumbers, cut veg, mushrooms, soft fruit): no — the carton will collapse within one or two cold-chain cycles.

How do I design a custom branded produce case?

Spec waxed or wax-alternative RSC corrugated at the appropriate ECT (32–44 for most produce), with a dieline sized to the standard pack-count for your commodity. Flexo print 1–4 colors on the outer liner. Include PACA mandatory text (packer, origin, variety, grade, net weight, lot code) and reserve a GS1-128 barcode area for PTI.

Our corrugated boxes page covers the structural options; food & beverage boxes 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 bundled into the per-case price in all standard distributor models. The exception is RPC programs where the restaurant pays a per-crate deposit refunded on return. Direct-from-farm programs may itemize packaging on the invoice; most don’t.

What's the biggest produce packaging mistake?

Three ties: shipping high-moisture produce in unwaxed corrugated (carton collapses mid-chain); missing or inaccurate PACA case marks (receiving rejection); and absent PTI case code at a mid-size or above receiver (invoice chargeback or load refusal). Each is avoidable with a one-page spec sheet before the first run.

The bottom line

Restaurant wholesale produce packaging is a standardized ecosystem: waxed corrugated RSC boxes for high-moisture, unwaxed for dry, RPCs at big-box receivers, 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 specialty formats for mushrooms, herbs, and wet-pack produce.

Pack-counts are standardized by commodity, PACA labeling is mandatory, PTI case coding is functionally mandatory at every mid-size and above receiver, and cold-chain temperature targets are commodity-specific. Done right, the packaging stack delivers 5–14 days of restaurant shelf life, zero chargebacks, and clean receiving acceptance.

Packaging Vista supplies waxed and unwaxed corrugated produce cases, PACA-compliant panel layouts, GS1-128 PTI case-code zones, and food-grade packaging for US produce shippers and restaurant commissary programs — 100-box minimum, no die or plate fees, 8–10 business-day production, and US customer support.
