About this product

A corrugated straight-line glued tube featuring partial-overlap end flaps. Delivered flat, it opens into a rectangular profile with end flaps that fold inward to create a protective rim.

In its default configuration, the flaps do not meet in the center, making it a practical bumper sleeve for large flat items. It can also be adjusted into a fully sealed box for automated packing lines.

Common uses

Furniture component protection
Frame edge bumpers
Automated packing lines for flat goods

Protective Bumpers And Automated Packing

Edge Protection For Flat Items

With the default partial-overlap flaps, this sleeve acts as a protective bumper. It covers the corners and edges of large, flat products while leaving the center exposed, reducing material use when full enclosure is not required.

Automated Case Sealing

The straight-line glued side seam and simple fold-over end flaps make this package a strong fit for automated packing lines and case sealers. Machines can open the flat blank, load the product, and apply adhesive to the ends.

Long-Axis Extrusion Packing

For long metal or plastic profiles, the open-ended bumper configuration protects the vulnerable tips and edges during transit without requiring the board area of a fully closed carton.

Material-Saving Partial Enclosures

When the broad face of a product does not need corrugated coverage, the short end flaps provide enough retention to keep the sleeve in place while cutting down on overall board consumption.

Furniture, Frames, And Flat Goods

Furniture And Millwork

Manufacturers of tabletops, doors, and large panels use partial-overlap sleeves to protect vulnerable edges during transit without paying for the corrugated board required to cover the entire broad face.

High-Volume Flat Goods

Operations packing frames, canvases, or flat components at scale benefit from the straightforward erection and machine-friendly end flaps, provided they have the equipment to apply adhesive or tape.

Industrial Extrusions And Profiles

Suppliers shipping long, rigid parts often rely on glued-end sleeves to bundle items together and protect the ends from impact, accepting the central gap as a practical tradeoff.

When To Consider Tuck Ends Or Full Seals

Manual Packing Without Gluing Equipment

Because the end flaps require adhesive or tape to stay closed, this sleeve can slow down manual fulfillment. If your packing stations lack gluing equipment, evaluate a tuck-end sleeve or a snap-lock bottom box that closes mechanically.

Full Enclosure Requirements

If the product requires complete protection from dust or abrasion, the default bumper configuration will not work. You must either adjust the flap height to create a full seal or evaluate a standard Regular Slotted Carton (RSC).

Flap Coverage And Sealing Methods

Flap Coverage And Material Efficiency

Decide whether the partial flaps provide enough retention and protection for your product. The default short flaps save board area, but extending them to meet in the middle increases material costs.

End Sealing Method

Determine how the ends will be secured. The major flaps must be glued or taped over the minor flaps. Adhesive applied by automated equipment is often a practical route for this package.

Board Grade And Flute Profile

Thicker corrugated flutes provide better edge protection but require larger slot widths and layer step creases to ensure the overlapping end flaps fold cleanly without binding.

Manufacturer's Joint Placement

The side seam is secured by a standard glue flap. Discuss with your converter whether this flap should be glued to the inside or outside of the tube, depending on your print and presentation needs.

Adjusting Flap Height And Clearances

Converting To A Full Seal-End Box

The default flap height is set to one-third of the box height. By adjusting this parameter so the flaps meet or overlap in the center, the bumper sleeve becomes a fully enclosed seal-end carton.

Layer Step Creases For Thick Board

When specifying heavier double-wall corrugated, the layer step creases can be adjusted to accommodate the extra material thickness when the major flaps fold over the minor flaps.

Slot Width Modifications

The slots separating the end flaps can be widened to prevent the corrugated board from binding or tearing during the final sealing process.

Packing details

Automated Erection Clearances

If using automated packing equipment, verify that the machine's handling mechanisms are compatible with the specific flap height and board grade chosen for the run.

Additional notes

Automated Case Sealing Compatibility

The straight-line glued side seam and simple fold-over end flaps make this package a practical fit for automated packing lines and case sealers.

Flap Height Adjustment

If full enclosure is needed, the flap height can be adjusted during specification so the major flaps close the gap entirely.

FAQs

Does this box fully enclose the product?

Not in its default setup. The end flaps are intentionally short, leaving a gap in the middle to act as a protective bumper. It can be modified into a fully closed box by extending the flap height.

How are the ends sealed?

The minor flaps fold in first, and the major flaps fold over them. They must be secured with tape or adhesive. There are no mechanical locks or tucks.

Will small items fall out of the ends?

If the flap height is left at the default partial-overlap setting, there is a central gap. Small or loose components will escape unless the flaps are extended to close the gap.

Is this suitable for manual packing?

It can be packed manually, but applying tape or glue to the end flaps by hand is slower than using a box with tuck ends or a crash-lock base. It is often better suited for automated case sealers.

How is it delivered?

The side seam is glued by the manufacturer, and the sleeve is delivered flat. It opens into a rectangular tube for loading.

Can this be made in heavy double-wall corrugated?

While possible, heavy double-wall board makes the end flaps difficult to fold and glue, especially by hand. It may also require specific manufacturing capabilities for the side seam.

Why use a partial-overlap sleeve instead of a full box?

For large, flat items like tabletops or frames, covering the entire broad face with corrugated board is often unnecessary and expensive. A bumper sleeve protects the vulnerable edges while reducing material usage.

Can the side seam be glued on the outside?

The manufacturer's joint can usually be glued to either the inside or the outside of the tube. Discuss this with your converter to ensure it does not interfere with your primary display panels or graphics.
