About this product

This open-top corrugated tray arrives flat and snaps into a rigid, locked shape when you push the opposite corners together. Because the factory pre-glues the interlocking base, your packing team skips bottom taping entirely.

While it shares the instant-setup mechanics of a standard crash-lock tray, this specific format is proportioned for elongated goods like pipes, extrusions, and rolled materials. The tradeoff is manufacturing complexity: the extreme length requires specific folder-gluer routing, making it a practical choice for high-volume fulfillment where pack-bench labor savings outweigh the initial production steps.

Common uses

Industrial extrusions and pipes
Rolled fabrics and materials
Internal kitting for long components
Structural beams and profiles

High-volume packing for elongated goods

Industrial extrusions and pipes

The long format supports rigid, elongated items. The interlocking base holds the weight, while the open top allows operators to drop parts in quickly before sliding the tray into an outer sleeve.

Rolled fabrics and materials

For fulfillment centers handling rolled goods, the instant setup removes the awkward step of trying to tape the bottom of a long, narrow tube.

Internal kitting for long components

Assembly lines use these as temporary holding trays for oversized parts, keeping them organized and protected before final integration.

Structural beams and profiles

Heavy metal or plastic profiles can be grouped inside the tray. The locked floor keeps the bundle together while the open top allows easy access for inventory counts.

Manufacturing, kitting, and fulfillment

High-volume fulfillment

When daily output targets are tight, removing the bottom-taping step across thousands of long-format orders yields measurable labor savings.

Industrial parts distribution

Suppliers shipping metal or plastic extrusions use these trays to group components securely before loading them onto pallets or into master transit boxes.

Assembly line staging

Manufacturing facilities use these trays to move long components between workstations, relying on the fast setup to keep the line moving without waiting for taped boxes.

When to consider a different base or closure

Short trial runs

If you are testing a new product line and only need a few hundred units, a manual snap-lock base or a standard slotted tray avoids the specific multi-point gluing steps.

Standalone parcel shipping

This tray has an open top. If the package needs to ship through a courier network on its own, compare it to a fully enclosed long-format box or plan to pair this tray with a sliding sleeve.

Close variants and lookalike dielines

The closest library neighbors include 0702, 0700, 0700a. Use this as a variant check if a buyer brings an old code, sample, or dieline that looks close. The deciding details are usually the lock, slot, closure, wall build, part count, or fold sequence.

Board thickness and production limits

Board thickness and lock binding

The crash-lock base relies on precise clearances to snap together. Heavy double-wall board increases the force required to pop the tray open and risks binding the tabs. Fine or medium flutes usually provide a smoother setup.

Maximum machine length

Because this tray is designed for long items, the flat blank can become extremely long. You will need to verify that the overall flat length fits within the converter's folder-gluer limits.

Outer shipping method

Since the top is open, you must decide how the tray will travel. It can slide into a master carton, receive a separate lid, or be stacked and strapped on a pallet.

Flute profile for diagonal folds

The 45-degree creases on the bottom flaps must fold cleanly for the auto-bottom to work. Selecting a finer flute often results in crisper hinges and a more reliable lock.

Adjusting the base clearance and seams

Base lock clearance

The factory adjusts the internal hook and notch clearance based on your exact board choice. Changing the material later requires recalculating these cuts so the base still locks smoothly.

Side seam placement

The manufacturer's joint can be placed on different panels depending on the artwork layout and the specific folding sequence required by the gluer.

Flap overlap adjustments

The bottom flaps can be slightly extended or reduced to ensure they clear each other during the folding process, depending on the board thickness.

Board and packing details

Flat delivery and storage

The trays ship completely flat. The glued side seam adds a slight thickness to the bundle, but they still store efficiently on pallets before use.

Standard versus long format

Standard proportions

If your product is not elongated, the standard crash-lock tray uses the exact same instant-setup mechanics but fits conventional square or rectangular footprints.

Additional notes

Short digital trial versus repeat run

A digital prototype cut on a sample table will not have the factory glue joints. To truly evaluate how easily the tray pops open on your pack bench, you need a sample that has been glued and crushed by a production machine.

FAQs

Route and shipping

Can this tray ship through a parcel network?

Not on its own. The open top provides no containment or dust protection. It needs to be paired with a lid, a sliding sleeve, or placed inside a master shipper for courier transit.

Board and finish

Does the auto-bottom work with heavy double-wall board?

It can, but heavy board makes the diagonal creases stiff. This increases the physical effort required by your packing team to pop the tray open, and the thick tabs are more likely to bind. We usually recommend testing a physical sample if you specify double-wall corrugated.

Quantity and production

Why does this tray require specific production equipment?

The crash-lock base requires a multi-point folder-gluer to apply adhesive to the bottom flaps before delivery. This machine takes longer to configure than standard equipment, making the tray more practical for repeat, high-volume runs.

Product fit

Will a very long tray fold correctly?

Yes, but extreme lengths can exceed the physical limits of standard folding equipment. If your product is exceptionally long, the production route will need to be verified against specific machine envelopes.

Packing labor

Do I need to tape the bottom after it locks?

No. The interlocking tabs and factory glue joints create a rigid floor that holds its shape without secondary taping.

First conversation

What product details help start a conversation for this tray?

Share the exact dimensions of your elongated product, the target order volume, and whether the tray will slide into an outer sleeve or sit on a pallet. This helps determine if the blank length fits standard production routes.

Inserts and fit

Can I use dividers inside this tray?

Yes. Once the base is locked, you can drop in corrugated partitions or foam inserts to separate multiple long items, keeping them from scratching each other.

Samples and prototypes

How should we test the pop-open resistance?

Because the base requires factory gluing, prototyping this tray digitally only proves the dimensions. A true test of the pop-open resistance requires a sample run through a production folder-gluer using your chosen board grade.
