About this product

This single-piece folding carton forms a rigid, four-corner glued tray with an integrated hinged lid and a tuck-in front closure. Designed for high-volume packing lines, it delivers a clean retail presentation and consistent reclosability for cosmetics, pharmaceuticals, bakery goods, and premium retail items.

Because it lacks the diagonal creases used for pre-gluing, this carton is supplied as a flat, unglued blank. It is usually erected and glued on an automated tray-forming machine at the packing site, making it efficient at scale while manual hand-packing operations may find it slow.

Common uses

  • High-volume bakery and confectionery
  • Cosmetics and pharmaceuticals
  • Retail-ready packaging
  • Gift food sets

High-volume retail and bakery packing

Automated retail packaging

The glued corners provide a rigid, bulge-resistant base that protects the product, while the hinged lid and tuck flap offer a premium, reclosable unboxing experience. It is a common choice for cosmetics, personal care, and high-end retail goods packed on automated lines.

Bakery and confectionery

Often used for pastries, chocolates, and specialty foods, the tray's wide base and low side walls make it easy to load products side by side. The side dust flaps help prevent contamination and provide a resting surface for the lid.

Gift food sets and jars

The flat base and straight walls accommodate glass-packaged products such as honey jars, preserves, or bottled beverages. The glued corners help the tray retain its shape when carrying heavier grouped items.

Pharmaceutical and medical packing

The clean interior and dust flaps provide a protected environment for medical devices or pharmaceutical bottles. The tuck lid allows end users to open and close the package repeatedly during the product's lifespan.

Packing lines, retail shelves, and e-commerce transit

High-volume packing facilities

This carton is efficient for operations equipped with tray formers. By shipping as flat, unglued blanks, it maximizes pallet density and reduces inbound freight costs compared to pre-glued cartons.

Retail-ready presentation

The clean lines of the glued corners and the continuous hinged lid create an uninterrupted front panel for branding. When configured with the display variant, it transitions from a transit box to a shelf-ready merchandiser.

E-commerce fulfillment

While the tuck lid provides a clean presentation, it relies on friction and may open during rough transit. For direct-to-consumer shipping, this tray often uses an outer shipping box or heavy sealing tape to keep the contents secure.

When to consider friction-lock or crash-lock alternatives

Manual packing operations

If the packing line does not use automated tray-forming equipment, hand-gluing four corners can be slow. An unglued friction-lock tray or a pre-glued crash-lock base may be worth comparing, as they can be erected by hand without adhesive.

Heavy stacking requirements

The mid-lid crease on the display variant reduces the structural integrity of the top face. If the package will face heavy top loads on a pallet, a solid lid or a double-wall tray may be worth comparing.

Tray forming, closure security, and display printing

Tray former compatibility

Verify the size limits and tooling tolerances of the tray-forming equipment. The machine should be checked to handle the specific board thickness and apply adhesive accurately to the four corner tabs.

Board grade and thickness

Standard folding boxboard is typical for retail goods. If using micro-flute corrugated board for heavier items, the tray former clearances and tuck flap dimensions should be adjusted to accommodate the thicker material.

Print and finish routing

The continuous front and top panels offer a large canvas for branding. If using the display header variant, the inside of the lid becomes the front-facing surface, which usually involves two-sided printing.

Closure security

Decide if the friction-fit tuck flap provides enough security for the distribution route. If the package will travel through mixed courier networks, tamper-evident labels or an outer shipper may be worth comparing.

Tuck flap friction, dust flap tapering, and window patching

Tuck flap friction

The insertion depth and corner radius of the tuck flap can be adjusted to fine-tune the opening experience. A tighter fit helps prevent accidental opening, while a looser fit makes it easier for consumers to access the product.

Dust flap tapering

The dust flaps attached to the side walls can be tapered to prevent interference when the lid is closed, ensuring a smooth, flat top surface.

Window patching

A die-cut window with a plastic patch can be added to the lid panel for product visibility. This modification slightly reduces the overall rigidity of the top face but improves retail appeal.

Board and packing details

Flat blank delivery

Unlike crash-lock cartons that are pre-glued by the converter and shipped folded flat, this tray is shipped as a completely unglued flat blank. This shifts the gluing process entirely to the packing facility.

Retail display header variant

Pop-Up Display Header (B40.20.82.50.35)

A retail-ready variant where the lid features a mid-panel crease and a locking tongue. Instead of tucking into the front wall, the lid folds back on itself and locks into the rear wall, creating a rigid, double-thick vertical display header. This usually involves two-sided printing if the header is branded.

Additional notes

Adhesive application zones

The corner glue tabs on the blank should be kept free of ink or varnish to ensure a secure bond during automated erection.

FAQs

Assembly and Equipment

Can this tray be assembled by hand?

While it is physically possible to apply adhesive and fold the corners manually, it is slow for volume packing. This carton is typically run on automated tray-forming machines. For manual packing, an unglued friction-lock tray is often a more practical choice.

Does this carton ship pre-glued?

It lacks the diagonal creases used to pre-glue and fold it flat. It ships as a flat, unglued blank and is glued at the point of packing.

Retail and Display

How does the display header variant work?

The B40.20.82.50.35 variant includes a crease across the lid and a locking slot on the back wall. The lid folds backward and locks into place, standing upright as a display header. Because the inside of the lid becomes the front of the display, two-sided printing is usually involved.

Shipping and Route

Is the tuck lid secure enough for e-commerce shipping?

The tuck flap relies on friction and may open during rough handling. For parcel shipping, the tray is often placed inside a secure outer shipper or sealed with heavy-duty tape or tamper-evident labels.

Materials and Fit

Can this be made from corrugated board?

Micro-flute corrugated can be used for added strength. However, the tray former tooling and the tuck flap clearances should be adjusted for the thicker material to prevent binding or cracking.

Design Options

Can a window be added to the lid?

A die-cut window with a plastic patch can be added to the lid panel for product visibility, though it slightly reduces the overall rigidity of the top face.

Assembly and Equipment

What kind of adhesive is used for the corners?

Automated tray formers apply adhesive to the corner tabs during erection. These tabs should be kept free of ink or varnish to ensure a secure bond.

Materials and Fit

How do the dust flaps affect the lid?

The dust flaps fold inward from the side walls to create a resting surface for the lid. They help prevent the lid from collapsing inward under light top loads and block dust from entering the sides of the closed tray.
