About this product

Heavy, dense, or fragile payloads often require more vertical protection than a standard shipping box can provide. This two-piece telescopic package pairs a base tray with a full-depth lid that slides completely over the sides, creating a double-wall perimeter for high stacking strength.

Unlike conventional telescopic boxes, the FEFCO 0301 design offsets the corner flaps between the base and the lid. By distributing the folded corrugated board across different panels, the corners avoid excessive thickness buildup. This allows the lid to slide on smoothly without binding, even when using thick double-wall material.

Common uses

  • Palletized industrial goods requiring high vertical compression resistance.
  • Reusable internal storage bins.
  • Archival and long-term document storage.
  • Premium presentation and kitting.

Heavy payloads and storage

Palletized industrial goods

The double-wall perimeter provides high vertical compression resistance, handling heavy stacking without crushing the bottom layers.

Reusable internal storage

The friction-fit lid can be removed and replaced repeatedly without degrading the box structure, making it useful for kitting or parts storage.

Archival and long-term storage

Maintains its shape over years of shelf storage, protecting heavy paper or document loads from dust and deformation.

Premium presentation and kitting

The smooth, uninterrupted lid provides a clean unboxing experience and a large surface for high-visibility printing, often used for high-end gift sets.

Industrial and distribution environments

Heavy manufacturing

A strong fit for metal parts, motors, or dense components that might break through the bottom of a conventional slotted container.

Print and paper distribution

Allows flat loading of dense paper stacks directly into the base tray, rather than dropping them down into a deep tube.

Museum and archival management

Chosen for long-term document protection, as the full-depth lid resists dust and the rigid corners prevent long-term sagging.

E-commerce gift boxing

Provides a premium unboxing reveal, though it requires an outer mailer or secure strapping to handle courier networks.

When to consider a different box style

When packing speed is the priority

A conventional slotted box (FEFCO 0201) requires half the assembly labor, making it a better choice when extreme vertical strength is not required.

When packing extremely tall or heavy items

A three-piece pallet box (FEFCO 0310) uses a separate sleeve and two caps, allowing heavy items to be loaded without lifting them over high walls.

Close variants and lookalike dielines

The closest library neighbors include 0300, EVC41220, 0306. 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.

Corner fastening and board clearance

Corner fastening method

The eight corners must be secured before use. Heavy-duty applications often rely on industrial stitching, while lighter loads may use tape or glue.

Board thickness and clearance

The lid must be scaled precisely to match the base and the board caliper. Changing from single-wall to double-wall requires recalculating the telescopic gap.

Delivery and assembly labor

Both pieces ship flat and demand manual or machine erection before the packing line can use them.

Closure for transit

The lid relies on friction and gravity. If the box travels through mixed courier networks, external strapping or tape prevents the lid from separating during transit.

Lid depth and slot profiles

Lid depth

The lid can be shortened to cover only part of the base if full double-wall strength is not required, reducing material usage.

Slot profiles

Corner slots can be adjusted with tapers or radii to make manual folding and alignment easier on the pack bench.

Thumb notches

Semi-circular cutouts can be added to the sides of the lid, making it easier for users to grip the base and lift the high-friction lid.

Board and packing details

Print surface

The uninterrupted top panel of the lid provides a large, flat area for branding, handling instructions, or routing labels.

Additional notes

Assembly labor expectations

Because this package requires erecting and fastening two separate trays, it demands roughly twice the pack-bench labor of a conventional slotted box.

FAQs

Assembly and Packing

Does this box lock together on its own?

No. The corners of both the base and the lid must be fastened with tape, glue, or industrial stitches before the box can be used.

Why use offset flaps instead of a standard 0300 design?

When you fold corrugated board, the corners get thick. If the base and lid flaps fold on the same sides, that thickness multiplies and the lid gets stuck. Offsetting the flaps moves the bulk to different sides, allowing a smooth sliding fit even with heavy double-wall board.

Route and Shipping

Can this box be shipped through standard parcel couriers?

It can, but the lid relies on a friction fit. Tumbling in a courier network causes the lid to separate unless packers apply strapping or tape.

How does it handle heavy pallet stacking?

Because the lid slides completely over the base, all four vertical sides become double-walled, providing strong resistance against vertical crushing.

Materials and Production

Can we switch board grades later without changing the design?

Changing board thickness requires recalculating the lid dimensions. If you move from a thin board to a thick double-wall board without adjusting the template, the lid will not fit over the base.

Is this a good fit for automated packing lines?

It is usually a poor match for standard linear folder-gluers. The cross-directional flaps and two-piece design mean it is typically erected manually or with specialized tray-forming equipment.

Assembly and Packing

How do packers load heavy items into this box?

Because the lid is completely removable, packers can place heavy or awkward items directly into the open base tray without having to lower them down into a deep tube.

Materials and Production

Why is this style used for premium or gift packaging?

The full-depth lid creates a clean exterior without visible tape seams on the top or sides. This offers a premium unboxing experience often called a bell box.
