Practical Uses for the Raised-Corner Tray
Shelf-Ready Packaging (SRP)
The dipped profile on the long walls allows shoppers to easily see and reach the product, while the raised corners provide the structural support needed to stack multiple trays on a pallet or retail shelf.
Produce and Agricultural Goods
The double-thick glued walls resist bowing, making this tray suitable for heavy, dense items that require open-top ventilation and vertical support.
Beverage and Heavy Jar Trays
The reinforced perimeter helps contain heavy primary containers, keeping them organized and upright during transit and display.
Club Store Multi-Packs
The combination of high product visibility and pallet-ready vertical support makes this a practical choice for bulk retail environments.
Retail and Supply Chain Fit
Automated Packing Lines
Because this tray lacks mechanical locking tabs, it is a strong fit for automated tray formers equipped with adhesive systems. It is built for repeat, high-volume erection.
Retail Presentation
The 180-degree fold-over flanges mean that the inside of the tray walls displays the same printed surface as the outside. This provides a clean, finished look on the shelf without requiring two-sided printing.
Palletized Distribution
The raised corners carry vertical loads, protecting the primary product from crush damage when trays are stacked multiple layers high.
When to Consider a Different Tray Style
Manual Assembly Without Adhesive
If you are packing by hand and do not want to use glue, this tray will be slow to assemble. Compare it to a roll-end tray with locking tabs, which locks together mechanically.
Parcel and Courier Shipping
This is an open-top tray. If the product needs to ship through a mixed-carrier courier network, it will likely require a master outer carton or shrink wrap to keep the contents secure.
Key Decisions for Production and Assembly
Assembly Method and Volume
This tray relies on adhesive. For repeat runs, an automated tray former makes the most sense. For short runs, manual assembly with adhesive is possible but labor-intensive. Confirm your assembly capabilities before specifying this design.
Board Grade and Fold Clearance
The strength of this tray comes from its 180-degree folded flanges. If the corrugated board is too thick, the folds may crack or resist gluing. Thinner board profiles are typically the most reliable choices for clean 180-degree folds.
Print Surface Planning
Leveraging the fold-over flanges allows the exterior print to wrap inside the tray. Discuss how this affects your artwork layout to avoid unnecessary two-sided printing costs.
Outer Shipping Requirements
Decide if the tray will travel on a pallet or if it needs to be packed into a master carton for individual parcel delivery.
Adjusting the Display Profile
Tuning the Display Window
The depth of the dipped center panel can be adjusted. You can balance the need for maximum product visibility against the need for lateral containment based on your specific product.
Corner Post Height
The raised corners can be extended or lowered to match the height of the primary product, ensuring the tray carries the vertical load instead of the goods inside.
Flange Width
The width of the 180-degree fold-over flanges can be modified, which changes how much of the printed exterior wraps over to the inside of the tray walls.
Packing details
Die-Cutting Tooling
Due to the stepped profile of the raised corners and the angled relief cuts for the flanges, this tray is typically produced using flatbed die-cutting tooling. It is generally not a fit for simple rotary slotting.
Additional notes
Board thickness and fold memory
The 180-degree folds create tension in the board, meaning the flaps will naturally try to spring open. A strong adhesive bond is required to hold the flanges flat, especially with thicker flutes.
FAQs
Can this tray be assembled without adhesive?
This specific design does not have mechanical locking tabs. It relies entirely on adhesive applied to the fold-over flanges to hold its shape.
Is this tray suitable for hand packing?
It can be loaded by hand once erected, but manually gluing the four 180-degree flanges is slow and labor-intensive. It is much faster when erected by an automated tray former.
Why are the corners higher than the side walls?
The raised corners act as structural posts to carry the weight of pallets or trays stacked above them. This allows the center of the side walls to dip lower, keeping the product visible to shoppers without sacrificing vertical strength.
Do I need two-sided printing for the inside of the tray to look good?
Usually, no. Because the top flanges fold 180 degrees inward and cover the inside walls, the exterior print surface wraps around to the inside. This provides a printed interior perimeter using only standard one-sided printing.
Can I use a heavy double-wall board for extra strength?
Heavy board grades should be tested carefully. The design requires the corrugated board to fold completely flat against itself. Very thick flutes may crack or create too much tension for the adhesive to hold securely.
Can I ship this tray through the mail?
Not on its own. As an open-top tray, it provides no top protection and cannot contain loose items if overturned. For parcel shipping, it usually needs to be placed inside a closed master carton.
How does this compare to a standard roll-end tray?
A standard roll-end tray uses mechanical locking tabs and slots to hold its shape, making it easy to assemble by hand. This tray uses glued flanges instead, which is often preferred for high-speed automated packing lines.
Does the dipped front panel weaken the tray?
The raised corners are designed to carry the vertical load. As long as the trays are stacked corner-to-corner, the dipped front panel does not compromise the overall stacking strength.
