Bakery, deli, and retail presentation
Bakery, deli, and takeout food
The unbroken bottom corners make this tray useful for food items that generate crumbs or release light grease. When produced with a poly-coated or grease-resistant board, the webbed gussets contain the contents far better than a standard slotted carton.
Premium retail and gift packaging
The tapered walls and integrated lid provide a distinctive pail or gift-box aesthetic. The front tuck closure allows customers to open and reclose the box easily without damaging the presentation.
Catering and event meal kits
For events where multiple items are packed together, the wide opening and tapered walls make loading simple. The flat storage profile helps caterers transport empty boxes efficiently before assembling them on site.
Confectionery and chocolate assortments
When paired with custom inserts, the tapered tray offers an elegant unboxing experience. The lack of glue seams on the interior keeps the presentation clean and focused on the product.
Manual packing and flat storage
Manual packing stations
Because this tray relies on mechanical folds rather than glue, it is erected by hand. Packers fold the walls upward, push the webbed corners inward, and secure the side locks. This makes it a strong fit for on-demand, store-level, or low-volume packing where automated erecting equipment is not used.
Pop-up retail and food trucks
Space is often limited in mobile or temporary retail setups. These trays ship and store completely flat, allowing vendors to keep a large supply on hand without taking up valuable floor space.
Low-volume specialty runs
Without the need for a folder-gluer during manufacturing, this carton is practical for short production runs. It is an accessible choice for seasonal promotions or limited-edition product launches.
When to compare glued or straight-wall alternatives
High-speed or automated fulfillment
If your packing line relies on rapid, one-handed setup, the manual folding of the webbed corners will slow down your operators. It is worth comparing a pre-glued crash-lock tray, which pops open faster but uses a folder-gluer operation.
High-density shelf storage or stacking
The tapered walls reduce vertical stacking strength and mean the boxes cannot sit completely flush against each other side-by-side. If maximizing shelf space or pallet density is critical, a straight-walled reverse-tuck or straight-tuck carton is worth comparing.
Board thickness, coatings, and closure security
Board thickness and flute limitations
This carton relies on the board folding cleanly on diagonal creases to form the webbed corners. Standard folding boxboard or solid bleached sulfate works well. Corrugated board is generally a poor choice, as the flute thickness can cause the corners to bind or crush during assembly.
Food-safe coatings
While the geometry prevents physical gaps at the bottom, the paperboard itself will absorb moisture unless treated. Specify a poly-coated or waxed interior if the tray will hold wet or greasy foods.
Print surface and interior branding
Because the lid is attached to the back wall, the inside of the lid and the interior of the tray will show the unprinted side of the board unless two-sided printing is specified. Consider this if the unboxing experience is important.
Closure security and tamper evidence
The friction-fit side tongues and front tuck lock are designed for easy opening. If the package is being delivered by a third-party service, a custom label or sticker over the front closure can provide simple tamper evidence.
Adjusting the taper and lock dimensions
Modifying the wall taper
The angle of the walls can be adjusted by changing the difference between the top opening and the base footprint. However, steep tapers can cause the internal webbed flaps to overlap awkwardly, so the proportions should be tested with a physical sample.
Tuck tongue width and friction
The width of the front locking tab can be increased to create a tighter friction fit in the receiving slot. This helps keep the lid secure during handling but may make it slightly harder for the consumer to open.
Lid flap depth
The front flap attached to the lid can be extended further down the front wall. A deeper flap provides more surface area for branding and can help stabilize the front panel.
Packing details
Parcel shipping and outer cartons
The friction-fit side tongues and front tuck lock are designed for retail hand-offs or local delivery. They may open during individual parcel delivery. If shipping directly to consumers via parcel, this tray is usually placed inside a corrugated outer shipper.
Front lock variants: EVF41181 vs. EVF41181a
EVF41181 (Front Flap Slot)
The standard version features a front flap attached to the lid that folds down over the front wall. The tuck tongue inserts into a slot on this flap.
EVF41181a (Over-the-Lid Tuck)
This variant changes the closure sequence. The tuck tongue extends from the front wall, folds backward over the front edge of the closed lid, and inserts into a slot located directly on the top lid panel.
Additional notes
Print surface and interior visibility
Because the lid is attached to the back wall, the inside of the lid and the interior of the tray will show the unprinted side of the board unless two-sided printing is specified.

FAQs
Can this tray be erected on automated packaging lines?
The webbed corners and side locking tongues rely on manual fold-and-hold assembly. It is designed for hand-packing stations, and is generally not suited for automated cartoners.
Can I make this box out of corrugated board?
The diagonal folds needed for the webbed corners will typically bind or crush if made from corrugated material. It performs well in standard folding carton paperboard.
Is the bottom of the tray liquid-tight?
The continuous webbed corners prevent physical gaps, making it very resistant to crumbs and light grease leaks. However, it is not truly liquid-tight unless the board is specifically coated and the folds are tightly compressed.
Does this box stack well?
Tapered walls naturally reduce vertical compression strength compared to straight walls. While it can support lightweight stacking, excessive top weight may cause the angled walls to bow.
Do I need tape or glue to keep the box closed?
The tray relies entirely on mechanical friction locks: side tongues to hold the walls up, and a front tuck tongue to secure the lid. Tape or labels are only added if you want tamper evidence.
Can I ship this box through the mail?
The mechanical locks may open during individual parcel delivery. For parcel shipping, this tray is usually packed inside a corrugated master carton.
Can I print on the inside of the lid?
Printing on the inside is possible, but it involves two-sided printing. Because the lid is an extension of the back wall, the interior of the box and the underside of the lid will show the unprinted side of the board by default.
How are these boxes delivered?
They are delivered completely flat. Because there are no glue seams, they take up very little space in storage and are folded into shape only when needed at the packing station.
