About this product

This one-piece folding carton combines a fast, glue-free setup with a highly secure closure. The base features webbed corners that fold inward, creating a solid, continuous floor that helps contain crumbs or small parts, while the hinged lid uses specialized ear hooks to lock firmly into the front wall.

Delivered flat and erected entirely by hand, it is a strong choice for retail kitting, apparel, and bakery applications where presentation and a positive mechanical lock matter more than automated packing speeds.

Product and Packing Fits for the Gusseted Locking Tray

Retail Kitting and Apparel

The clean lines and secure closure make this tray excellent for presenting lightweight retail goods. The ear hooks keep the lid firmly in place on the shelf without requiring clear wafer seals.

Bakery and Food Service

Because the corners are webbed rather than cut, the base has no open slits. This continuous floor helps contain crumbs, making it a natural fit for pastries and dry food items when produced with the right coated board.

Lightweight Parts and Hardware

For small, dry components that need to be kept together, the solid base prevents pieces from slipping out, while the locking lid keeps the contents secure during hand-offs.

Cosmetics and Personal Care

The unglued, flat-shipping design allows for high-quality print on all exterior surfaces, providing a premium unboxing experience for lightweight cosmetic sets.

Manual Packing and Retail Environments

Manual Packing Operations

This package is designed entirely for hand assembly. The inward-folding gussets and the ear-hook insertion require human dexterity, making it highly efficient for manual packing stations but unsuitable for automated carton erectors.

In-Store Assembly and Fulfillment

Because the trays ship flat and require no glue or tape, retail staff can quickly fold them into shape on demand, saving back-room storage space.

Short-Run Promotional Campaigns

The lack of a gluing process reduces manufacturing setup time, making this a practical choice for limited-edition kits or seasonal retail promotions.

When to Compare Other Tray Styles

Heavy Products or Parcel Shipping

The single-ply walls and paperboard construction are meant for retail display and direct hand-offs. If the package needs to handle courier delivery or hold heavy components, a corrugated roll-end tuck-top mailer will provide better crush resistance.

High-Speed Automated Lines

If your operation relies on automated tray formers, you should look at glued four-corner trays or machine-erected crash-lock styles that do not require complex manual gusset folding.

Liquid or High-Moisture Contents

If the product contains liquids, the webbed corners alone will not prevent leaks. You should look at fully sealed plastic trays or heavily coated boards designed specifically for liquid containment.

Board, Closure, and Packing Choices

Material Thickness Limits

The webbed corners must fold 180 degrees flat against the side walls. This requires standard folding boxboard or very thin micro-flute. Standard corrugated board will bind, crush, or crack during assembly.

Back Wall Ventilation Holes

The template includes two circular cutouts on the back wall, often used for ventilation or display access. These can be easily removed from the design if a solid back wall is preferred.

Coating and Finish Requirements

If packing food or items with slight moisture, the board will need an appropriate barrier coating, as the paperboard itself is not inherently liquid-tight despite the gapless corners.

Print Coverage and Branding

Since there are no glue flaps to mask off, the entire flat blank can be printed or varnished in a single pass, allowing for continuous graphics across the exterior.

Lock Adjustments and Ventilation

Lock Tension and Fit

The size of the ear hooks and the receiving slits can be adjusted to match the exact thickness of your chosen board, ensuring the lock holds securely without tearing during repeated opening.

Removing Ventilation Cutouts

The circular holes on the back wall can be deleted from the die-cutting template if your product requires a completely enclosed rear panel.

Webbed Corner Angles

The geometry of the corner folds can be slightly modified to accommodate different tray heights, though this must be carefully tested to ensure the board does not bind.

Packing details

Flat Delivery and Storage

Because the tray requires no pre-gluing by the manufacturer, it ships completely flat. This maximizes pallet density and reduces storage space in your facility before use.

Additional notes

Uninterrupted Print Surfaces

Because there are no glued seams, the entire exterior of the flat blank can be printed, varnished, or coated in a single pass without masking off glue zones.

FAQs

Does this tray require glue or tape?

No. The tray holds its shape through the tension of the folded corner gussets and the mechanical lock of the lid's ear hooks. Tape is only necessary if you require tamper evidence for shipping.

Can this be made from standard corrugated cardboard?

Generally, no. The webbed corners must fold completely flat. Standard corrugated board is too thick and will crack or bind. It is best suited for paperboard or very thin micro-flute.

Is this box safe for parcel shipping?

On its own, it is not recommended for parcel networks. The ear hooks can pop open under drop impacts. For courier delivery, it should be placed inside a corrugated outer shipper or securely taped.

Will the bottom leak?

The webbed corners mean there are no cuts or slits at the base of the tray, making it highly resistant to leaking dry goods like crumbs or powders. Liquid resistance depends entirely on the board coating.

Do I have to keep the holes on the back wall?

No. The circular cutouts can be removed from the die-cutting template if your product does not require ventilation or rear access.

Can this tray be erected by a machine?

The simultaneous folding of the corner gussets and the insertion of the ear hooks are designed for human dexterity. Standard automated tray formers typically cannot handle this specific fold sequence, making it a better fit for hand-packing stations.

How is the tray delivered?

It is delivered completely flat. Because there are no glued seams, the manufacturer does not need to run it through a folder-gluer, which keeps the flat profile very thin for palletizing.

Can I test the lock tension before ordering?

Yes. Because the ear hooks rely on precise friction and board thickness, it is highly recommended to request a physical sample in your chosen material to verify the lock engages smoothly without tearing.
