PET Egg Carton Sizes & Capacities: 6 to 30 Eggs Explained
Short answer: a PET egg carton is chosen by three things — egg count, egg weight class, and sales channel. Our blister-formed PET egg boxes cover eight standard capacities — 6, 8, 10, 12, 15, 20, 24 and 30 eggs — each engineered around egg weight classes from 40 g up to 70 g, in clear or black PET. Pick the wrong count and you pay more per egg and waste pallet space; pick the wrong cell depth and eggs rattle or crack in transit. This guide walks through every capacity, how to match cells to your egg weight, and what to confirm before you place a wholesale order.
PET (polyethylene terephthalate) is the same food-contact plastic used for bottled water. When a food-grade PET sheet is blister-formed into a tray of cradled cells, it creates an egg carton that is rigid, transparent, moisture-resistant and recyclable — the combination that molded pulp cannot offer and that supermarkets increasingly ask for. If you are still deciding between plastics and fiber, start with our PET vs pulp egg tray comparison, then come back here for the sizing decision.
Why Carton Capacity Is a Business Decision, Not Just a Number
Capacity drives three separate costs at once. First, packaging cost per egg: a 30-egg tray uses far less material per egg than six 5-egg cartons holding the same volume, so bulk counts always win on unit cost. Second, freight cost: cartons stack, and the stack height that fills a standard export carton differs by capacity — an inefficient count choice ships air. Third, shelf economics: a price-conscious hypermarket wants high-count value packs, while a boutique grocer wants a small, premium-looking carton that carries a higher margin per unit sold.
There is also a weight dimension that buyers often miss. A cell designed for a 45 g egg will let a 65 g egg sit proud of the lid, and a snap-fit lid will either not close or close under stress — the single most common cause of cracked eggs in transit. So the right question is never just “how many eggs?”, but “how many eggs of what weight, going through which channel?”.
The Eight Standard PET Egg Carton Capacities
Our stock tooling covers eight counts. Within one order you can mix capacities — most distributors combine a retail count with a bulk count in a single shipment.
| Capacity | Best for | Why buyers pick it |
|---|---|---|
| 6 eggs | Supermarket trial packs, premium and organic ranges | Small footprint, premium shelf presence, easy trial purchase |
| 8 eggs | Convenience retail and value packs | Sits between single-use small packs and the dozen |
| 10 eggs | Daily retail in many Asian and Middle East markets | Common count for household shopping trips |
| 12 eggs | North America and EU dozen retail | The default dozen — retailer expectation |
| 15 eggs | Family-size retail packs | Extra value without jumping to bulk formats |
| 20 eggs | Farm shops and wholesale counters | Retail look with mid-volume handling |
| 24 eggs | Bulk retail and food service | Two dozen in one handling unit |
| 30 eggs | Farm wholesale, bakeries, food service | Lowest packaging cost per egg, pallet-efficient |
The tray footprint (length × width × closed height) varies with capacity and egg weight class, and we provide the dimension sheet for each SKU on request — always confirm it against your shelf plan or carton inner dimensions before ordering.
Matching Tray Cells to Egg Weight
Eggs are graded by weight, and our PET egg boxes are engineered around the three commercial weight classes below. The cell depth and cradle diameter — not just the count — decide whether the lid closes cleanly and the eggs survive handling.
| Egg weight class | Tray cells designed for | Typical market use |
|---|---|---|
| 40–50 g | Small to medium eggs (S–M) | Standard retail eggs, liquid-egg operations |
| 50–60 g | Medium to large eggs (M–L) | Most supermarket eggs worldwide |
| 60–70 g | Large to extra-large eggs (L–XL) | Premium, free-range and farm brands |
The practical rule: tell us your average egg weight before choosing a capacity. A 30-egg tray built for 50–60 g eggs will underperform with 65 g eggs. When buyers send us their egg weight range and target count, we confirm the matching mould in the quotation — that single detail prevents most transit-breakage complaints. For a full export ordering workflow, see our egg packaging for export buyer’s guide.
Capacity by Sales Channel: How Buyers Actually Choose
| Channel | Recommended capacities | What matters most |
|---|---|---|
| Supermarket retail | 6, 10, 12 | Shelf transparency, brand printing, premium look |
| Farm shop / farmers market | 12, 15, 20 | Stackability, honest farm-fresh presentation |
| Wholesale / distributor | 20, 24, 30 | Stacking strength, cost per egg, pallet fill |
| Bakery & food service | 30 | Bulk handling, consistent cell fit |
| E-commerce / D2C parcel | 6, 8, 10, 12 | Breakage protection inside parcel networks |
Why transparency matters so much in retail: shoppers read egg freshness through the shell — size uniformity, cleanliness, colour. A clear PET carton turns that inspection into a selling moment instead of a risk. We cover the psychology in detail in why clear packaging sells more.
Clear or Black PET: Choosing the Look That Sells
| Clear PET | Black PET | |
|---|---|---|
| Shelf effect | Shows shell colour and uniformity at a glance; “nothing to hide” freshness cue | Premium, high-contrast backdrop that hides shell imperfections |
| Best for | Supermarket eggs, farm-fresh positioning | Boutique and organic ranges, dark premium branding |
| Print pairing | Works with any label or print colour | Light-coloured or foil print pops against the dark body |
Both colours come from the same food-grade PET stock and the same moulds, so switching between them is a production choice, not a tooling cost. Many exporters run clear for the mainline retail count and black for the premium range in the same order.
Snap-Fit Closures, Stacking Columns and Transport Strength
Two structural features decide whether eggs survive the journey. The first is the snap-on closure with shock-absorbing posts: the lid seats onto the base with a positive click, so it cannot detach accidentally, and the posts absorb shock instead of passing it to the shell. The second is the stacking support column design: trays carry vertical load through the columns rather than through the eggs, so filled cartons can be stacked in warehouses and on pallets without crushing the bottom layer — and the non-slip fit keeps stacks from sliding apart.
High PET transparency completes the package: buyers and end consumers can inspect eggs and spot damaged ones immediately, without opening the carton. That inspection speed matters on the farm line and in the supermarket aisle alike.
Export Packing: From Carton to Pallet
Empty PET egg cartons ship nested, which is where most of the freight saving lives: thousands of trays compress into a standard export carton, and cartons palletise into a container with almost no trapped air compared with rigid moulded crates. Standard export cartons and pallet packing are both supported — tell us your destination port and container preference and we quote the packing configuration with the carton.
If you are planning a first container, our export buyer’s guide covers packing sequence, compliance paperwork and supplier vetting in depth; this checklist helps you shortlist a factory-level supplier before you commit.
Custom Branding on PET Egg Cartons
Both clear and black PET egg boxes support logo printing and full OEM/ODM customisation — from a single-colour farm logo on the lid to a branded family range across multiple capacities. Because the cartons are blister-formed from sheet stock, tooling for a custom cell or embossed pattern is far cheaper than injection tooling, which is why branded egg programmes usually start here. Send your artwork and target capacity, and we return a print proof and size recommendation before production.
How to Order: Samples, MOQ and Lead Time
The ordering flow is deliberately short: (1) send your egg weight class, target capacity and monthly volume; (2) we confirm the matching mould and return a quotation within 24 hours; (3) free samples are arranged so you can test lid fit and stacking with your own eggs; (4) mass production follows after sample approval. MOQ depends on capacity and printing scope — stock capacities without print run the lowest. For the full purchasing mechanics, read OEM food packaging: MOQ, samples & lead time explained.
One more sourcing note: if your market rewards sustainability messaging, PET’s recyclability and the option to run both fibre and plastic ranges from one supplier can simplify your compliance story — we supply molded pulp egg trays alongside the PET line, so mixed programmes stay under one roof.
Frequently Asked Questions
What capacities are available in your PET egg cartons?
Eight standard capacities: 6, 8, 10, 12, 15, 20, 24 and 30 eggs. Trays are engineered for egg weight classes of 40–50 g, 50–60 g and 60–70 g, and you can mix capacities within one order to cover retail and bulk channels at the same time.
Which carton should I use for larger eggs?
Match the tray to your egg weight, not just the count. Eggs of 60–70 g need cells designed for that class — a tray built for 50–60 g eggs will not close cleanly under larger shells. Send us your average egg weight and we confirm the correct mould in the quotation.
Are PET egg cartons stackable for transport and storage?
Yes. Our trays use a stacking support column design, so vertical load passes through the columns rather than the eggs. Filled cartons can be stacked on pallets and in warehouses, and the non-slip fit keeps stacks stable.
Is PET safe for direct contact with eggs?
Yes. Our PET egg boxes are made from 100% food-grade PET, the same food-contact plastic used for bottled water, and the blister-formed surface is smooth, moisture-resistant and easy to keep clean.
Should I choose clear or black PET egg boxes?
Choose clear when freshness transparency is the selling point — supermarkets and farm-fresh ranges. Choose black for a premium, boutique look that hides shell imperfections and makes light-coloured printing pop. Both use the same moulds, so you can run both in one order.
Can I print my brand on the cartons, and how do I get samples?
Yes — logo printing and full OEM/ODM customisation are supported on both colours. Send your artwork, egg weight and target capacity: you receive a size recommendation and quotation within 24 hours, and free samples are arranged so you can test lid fit before mass production.
