Retail Display And Grouped Product Presentation
Retail shelf-ready packaging (RRP)
The open top provides unobstructed visibility for product labels, while the double-wall ends present a clean, finished edge to the consumer. It works well for holding jars, bottles, or canned goods securely on the shelf.
Inner kitting and organization
When paired with a master shipper or a telescopic lid, this tray acts as a rigid base to keep multiple components organized during transit and unboxing.
Grouped cosmetics and premium food
The lack of visible glue seams and the clean folded edges make this tray suitable for high-end presentation, provided the board grade is chosen to prevent cracking on the tight folds.
Work-in-progress (WIP) manufacturing trays
For internal plant use, the quick manual setup and flat storage make it an efficient temporary carrier for parts moving between assembly stations.
Shelf-Ready And Inner-Carton Applications
High-volume automated fulfillment
While often folded by hand for short runs, this tray is compatible with conventional plunger-style tray forming equipment, allowing it to scale into automated packing lines.
Hand-packed short runs and trials
Because it requires no gluing during conversion, it is highly cost-effective for short runs, prototypes, and seasonal promotions where manual assembly is acceptable.
Retailers requiring glue-free packaging
Some retail or sustainability guidelines prefer single-material, unglued packaging to simplify recycling streams at the store level.
When To Compare Glued Or Covered Packaging
High-volume manual packing
If operators must erect thousands of trays by hand, the repetitive motion of folding and locking the ends can cause fatigue. A pre-glued crash-lock tray or a four-corner glued tray may be a faster, more ergonomic choice.
Standalone parcel delivery
This tray has an open top and relies on friction locks. It requires an outer shipping box for parcel delivery, as the open top leaves products exposed.
Board Thickness, Grain Direction, And Packing Route
Board thickness and lock clearance
The fold-over panels must accommodate the exact thickness of the board. If the material is changed later, the die must be adjusted, or the double walls will bulge and the nibs will fail to reach their locking slots.
Grain direction for fold-over panels
The 180-degree fold on the end walls places heavy tension on the board. Specifying the grain direction to run parallel to these folds reduces the risk of the outer liner cracking.
Hand folding versus tray-forming equipment
Knowing whether the tray will be formed by hand or by a machine helps determine the necessary tolerances for the locking nibs and side tabs.
Outer shipping requirements
Because this is an open-top display tray, buyers must plan for a master carton or shrink wrap to secure the trays during palletized transit.
Adjusting Lock Tolerances And Wall Heights
Locking nib dimensions
The length and height of the locking nibs can be adjusted. Larger nibs provide a more secure hold but require more force to seat, while smaller nibs are easier to assemble but may pop out under pressure.
Wall height and base proportions
The height of the tray can be modified, but it must remain proportional to the base width to ensure the fold-over panels do not overlap or interfere with each other during assembly.
Side tab bevel angles
The angle of the side tabs can be adjusted to ensure they clear the fold-over panels smoothly during assembly, especially for thicker board grades.
Board and packing details
Friction lock sensitivity
Surface finishes, such as heavy UV coatings or laminations, can reduce the friction between the panels. This may cause the locks to slip if the tray is subjected to outward pressure.
Variant Tray Styles
B20.01.00.00.a (Modified side tabs)
Adjusts the horizontal taper of the side tabs to change how they clear the fold-over panels during assembly.
B20.01.00.00.b (Modified lock offset)
Uses a different panel correction logic for the tongue offset, altering the exact positioning of the locking nibs along the base crease.
Additional notes
Surface coatings and lock retention
Slippery interior coatings can reduce the effectiveness of the friction locks. If a heavy coating is required, the lock dimensions may need to be tightened.
FAQs
Assembly and Packing
Does this tray use glue or tape?
The tray relies entirely on mechanical friction locks. The end walls fold over the side tabs and lock into slots on the base without adhesive.
Can this tray run on automated packing lines?
The design is compatible with conventional automated tray formers that use a plunger and die system to fold and lock the walls in one motion.
Materials and Fit
How does board thickness affect the tray?
The fold-over panels are cut to wrap exactly around the side tabs. If the board is thicker than specified, the panels will bind and the locks will not seat. If it is thinner, the locks may be too loose and pop open.
Does this design work with corrugated board?
It is generally designed for folding carton board. Using micro-flute corrugated requires heavy adjustments to the fold allowances and increases the risk of the board cracking on the 180-degree folds.
Shipping and Route
How does the tray handle heavy products?
It can hold grouped heavy items like jars if the base is supported, but lifting a heavily loaded tray by its ends can cause the base to sag or the friction locks to dislodge.
Can this tray be used for parcel shipping?
The open top and friction locks require it to be placed inside a master shipper or mailer for parcel delivery.
Materials and Fit
What happens if the locking nibs are too small?
If the nibs are reduced too much, the friction lock becomes weak, and the fold-over panels may pop open under the outward pressure of the packed products.
Assembly and Packing
How is the tray delivered?
Because it requires no gluing during manufacturing, it is delivered completely flat, which maximizes pallet density and reduces shipping space.
