Retail and Presentation Uses
Retail Bakery and Confectionery
The rounded ends provide a premium, basket-like feel for pastries, chocolates, or specialty foods. The open top is typically flow-wrapped or shrink-wrapped.
Gift Hampers and Assortments
Acts as a rigid base for kitted products, using the tall ends to contain the items and display promotional graphics.
Inner Sliding Trays
Can be paired with a custom sleeve, where the rounded ends serve as pull tabs or decorative closures.
Specialty Food and Deli Presentation
Useful for displaying wrapped sandwiches, charcuterie, or deli items where the high ends frame the product on the shelf.
Packing Line Contexts
High-Volume Automated Packing
The standard flat-blank version is a strong fit for facilities equipped with plunger-style tray formers.
Hand-Packing Operations
For manual fulfillment, the design can be modified with tab-and-slit locks or pre-glued webbed corners to eliminate the reliance on on-site gluing equipment.
Co-Packing and Kitting Facilities
When products are assembled and overwrapped in a secondary location, the pre-glued webbed variant allows for rapid assembly without machinery.
When to Consider a Different Tray Style
Standard 4-Corner Glued Trays
If the packing job does not call for rounded presentation ends, a standard rectangular tray may be a simpler choice.
Trays with Lids
If the product will be stacked or calls for top protection without relying on a separate outer shipping box, a lidded tray or carton is worth comparing.
Fit, Board, Print, and Packing Choices
Assembly Method
Decide whether the trays will be formed on an automated line or if a manual-setup version makes more sense. This completely changes the corner design.
Board Choice and Finish
The tall rounded ends are very visible. Selecting a solid bleached board or folding boxboard ensures clean white edges and excellent print reproduction.
Nesting and Waste
The curved ends create irregular shapes on the raw material sheet. The height and curve radius can be adjusted to balance presentation goals with material efficiency.
Print Surface and Branding
The tall rounded ends act as built-in billboards. Decide whether the inside of the ends will be visible to the consumer, which often involves two-sided printing.
Corner and Rim Adjustments
Corner Locking Mechanisms
The standard glue tabs can be replaced with friction locks for glue-free hand assembly, or webbed corners for leak resistance and quick setup.
Fold-Over Hems
For a premium finish, the top edges of the side walls can be folded over and glued inward, hiding the raw paperboard edge and increasing rigidity.
Tapered Walls
The side walls can be angled slightly inward or outward to change the visual profile or allow empty trays to nest inside one another.
Board and packing details
Nesting waste and material efficiency
The large rounded ends mean the flat blanks do not interlock perfectly on a master sheet. Adjusting the curve radius slightly can sometimes improve material yield.
Film overwrapping
The tray is often used with shrink wrap or flow wrap. The board should be stiff enough to withstand the tension of the film without the rounded ends bowing inward.
Assembly Variants
Tab-and-Slit Lock (F20.37.00.00.a)
Uses mechanical tabs instead of glue, making it practical for manual assembly without machinery.
Webbed Corners (F20.37.00.00.b)
Adds diagonal corner folds, allowing the tray to be pre-glued by the factory and opened quickly by hand.
Hemmed Edges (F20.37.00.00.d)
Includes a fold-over hem on the walls for a cleaner, reinforced rim.

FAQs
Assembly and Route
Can this tray be shipped flat and opened quickly?
The standard base design is supplied as a flat blank and glued during erection. If the packing line relies on a tray that ships flat and opens quickly, the webbed-corner variant can be pre-glued at the factory.
Does this tray use tape or glue?
The base design uses adhesive applied by a tray-forming machine. When a glue-free option is better for hand-packing, it can be configured with mechanical locking tabs.
Shipping and Protection
Is this suitable for shipping in the mail?
This is a primary presentation tray with an open top. An outer shipping box is usually added for parcel networks.
Design and Fit
Can the rounded ends be adjusted?
The height and the exact curve of the ends can be modified to fit the product, though very tall ends will increase the overall footprint of the flat blank.
Materials and Finish
What materials fit this design?
Folding carton grades like solid bleached sulfate (SBS) or folding boxboard (FBB) are common choices because they fold cleanly and provide a smooth surface for printing on the large end panels.
Product Fit
Can it hold liquids or greasy foods?
The standard glued corners are not liquid-tight. For bakery items, a poly-coated board and webbed corners are often used to help contain crumbs or light grease.
Shipping and Protection
Can these trays be stacked on a retail shelf?
Because the top is open and the rounded ends do not provide a flat resting surface, these trays are not designed to be stacked directly on top of one another.
Design and Fit
How does the rounded end affect material yield?
The large curved panels create irregular shapes on the raw material sheet, which can increase nesting waste compared to a standard rectangular tray. Adjusting the curve radius can sometimes improve the layout.
