What makes a strawberry carton different from a general box?
A strawberry carton is built around how the packer loads it and how the fruit sits inside, so the first brief should cover the packed footprint, depth, visibility, ventilation planning, and stacking. A tray or liner can change the contact path and the amount of usable carton space.
Use inside length x width x depth for the fit. A common packaging tolerance reference is about 1/16 in, or 1.5 mm, but fresh produce varies, so test representative strawberries through loading, closing, and handling before the dieline is final.
Which carton structure fits the packing motion?
Base construction determines whether a hand-packed carton stays open while it is filled and closes without fighting the contents. A folding carton is a paperboard package cut and creased from one flat sheet, while a sleeve is a printed wrap around an inner pack.
| Structure | Typical use | Check before approval |
|---|---|---|
| Straight tuck end | Folding carton with a familiar tuck closure | Does the tuck clear the fruit and close repeatedly? |
| Reverse tuck end | Folding carton with the tuck direction reversed | Does the opening suit the packing station? |
| Auto-lock bottom | Formed base for hand assembly | Does the bottom stay locked under the filled load? |
| Crash-lock base | Pre-glued locking base | Can staff form it without turning the product? |
| Mailer, roll end tuck top, FEFCO 0427 | Ship-oriented opening and closure | Does the structure suit delivery and stacking? |
| Sleeve with tray or liner | Printed outer wrap around an inner pack | Does the inner pack control the fruit contact path? |
What board and window materials work for a strawberry carton?
SBS, C1S, and C2S are paperboard references commonly used for printed cartons in the 12 to 24 pt range. Kraft board is commonly around 18 to 24 pt when the natural board tone is part of the design. The board caliper is the thickness of the sheet, and it affects fold behavior, stiffness, and the space inside the finished carton.
Corrugated cartons use E, B, or C flute. Flute is the shaped paper layer between liners, so the grade changes cushioning, print surface, and stacking behavior. 32 ECT is a common corrugated strength reference. For a clear panel, PET window film is commonly around 0.2 to 0.3 mm. The window patch needs to clear scores, glue areas, and the product-facing surface.
Which print finish should I put on the carton?
Offset CMYK is a common choice for detailed paperboard graphics, while digital printing can suit a short run or an early design check; flexo is commonly associated with corrugated surfaces. Matte or gloss lamination changes the surface and scuff behavior. Soft-touch, spot UV, foil stamping, embossing, and debossing add separate production layers, so keep them clear of scores, folds, glue tabs, and high-abrasion contact points.
The proof catches expensive mistakes while they are still lines on a screen. Check the dieline, panel sequence, bleed, loading direction, glue areas, crease positions, artwork registration, barcode size, ink coverage, and copy near scores. RGB art can shift when converted for press, low-resolution art can show jagged edges, and missing bleed can leave an unprinted sliver at the cut.
How should food-contact use be handled?
Direct contact changes the material conversation. List whether strawberries touch the carton, a liner, a tray, a pouch, or another inner component, because board, coating, ink, adhesive, and barrier choices follow that path. Ask us about food-contact options for your product.
Run a real packing test. Watch whether fruit rattles inside the insert, whether the closure presses the contents, whether the window stays clear, and whether the filled carton stacks in the intended orientation. A retail-facing carton also needs the front panel and window position checked after handling.
Which catalog references can help scope the carton?
The custom cigarette carton boxes page is a folding-carton reference for tuck panels and printed surface planning. Use the same carton construction example to discuss closure sequence, then compare the printed carton reference while the strawberry carton is scoped. These links show structure only. The fruit arrangement, contact path, and loading test control the final design.
What should go into the quote request?
Send the filled inside dimensions, product arrangement, loading direction, tray or liner details, window preference, board direction, artwork status, finish layers, and ship-to location. The package should be quoted from the actual job, including whether it travels inside an outer shipper and how it is stacked.

Start with a custom packaging solution after the packed fruit and contact path are measured.
Frequently Asked Questions
What structure is best for a strawberry carton?
The best strawberry carton structure depends on the packed fruit, loading motion, closure, and stacking path. Straight tuck end and reverse tuck end cartons create different openings, while auto-lock and crash-lock bases change bottom assembly. A mailer, roll end tuck top, FEFCO 0427, or sleeve with tray can suit a different delivery or presentation path. Test the filled carton before final approval.
How thick should a strawberry carton be?
Printed strawberry cartons commonly use SBS, C1S, or C2S paperboard in the 12 to 24 pt range, while kraft board is commonly around 18 to 24 pt. Corrugated options include E, B, and C flute, with 32 ECT as a common strength reference. The right material depends on the filled weight, stacking, folds, window, and contact path.
Should a strawberry carton include a window?
A strawberry carton can use a PET window when product visibility matters. PET window film is commonly around 0.2 to 0.3 mm, but the patch still needs clearance from scores, glue areas, cuts, and the fruit. Check whether the window weakens a panel or changes the contact path, then test the filled package through packing and handling.
What measurements should I send for a strawberry carton?
Send inside length x width x depth, the packed fruit arrangement, loading direction, and any tray or liner dimensions. About 1/16 in, or 1.5 mm, is a common packaging tolerance reference, but strawberries vary in size. Measure the actual packed product and run a loading and closing test before the dieline is approved.
What if strawberries touch the carton directly?
Direct contact means the carton materials and finishes need to be checked against the intended use. Identify every surface that touches the strawberries, including board, coating, ink, adhesive, liner, or tray. Ask us about food-contact options for your product. A printed finish alone does not establish whether the complete carton is suitable for direct contact.
