FEFCO 0219

Snap-Lock Box with Locking Lid

This snap-lock box combines a fast-erecting bottom with a secure tongue-lock lid. Known as FEFCO 0219, it is delivered flat, pops open, and locks together without tape, creating a clean, unbroken exterior that works well for retail shelves, hanging displays, and premium kitting.

Because the base relies on interlocking flaps rather than tape, this carton is built for presentation and light-to-medium payloads. The specialized front-panel lock keeps the lid firmly shut during handling, while native cutouts allow the package to hang on retail pegs or secure internal plastic components.

Retail display and secure kitting

Hanging retail displays

The native cutouts on the top panel allow the carton to hang directly on retail pegs. The tongue lock ensures the weight of the product does not pull the lid open while suspended.

Premium unboxing and kitting

For sales kits or multi-part assemblies, the tape-free exterior keeps branding clean. The front lock provides a satisfying tactile snap when closed and allows the recipient to reclose the package neatly.

Component packaging with plastic inserts

The top cutouts can be sized to grip the neck of a plastic holder or specialized internal component, keeping the primary item centered and visible when the lid is opened.

In-plant kitting and assembly

For internal workflows where parts move between stations, the tool-free base speeds up the packing bench, while the secure lid keeps components contained during transit across the facility.

Consumer goods and parts distribution

Consumer electronics and accessories

Brands use the secure closure and hanging capability to display cables, chargers, and small devices on store hooks without requiring blister packs.

Manual fulfillment lines

When packing volume is high but order sizes vary, the snap-lock base removes the bottleneck of taping the bottom of every carton, while the tongue lock provides a secure final seal.

High-value parts distribution

Distributors shipping lightweight, premium components use this style to provide a clean presentation upon arrival, avoiding the messy look of cut tape.

When to consider a different box style

Heavy industrial payloads

The friction-locked base cannot hold the same weight as a taped floor. If you are packing dense metal parts, a standard taped carton or a glued crash-lock base provides more floor support.

Standalone parcel shipping

The mechanical locks are vulnerable to bursting if dropped by a courier. For direct-to-consumer shipping without an outer master carton, consider a roll-end mailer or plan to use a heavy-duty outer seal.

Standard retail without hanging needs

If you do not need the extra security of the tongue lock or the hanging cutouts, a standard tuck-top snap-lock carton uses a simpler cutting die and is slightly faster to close.

Board, fit, and production choices

Board grade and flute profile

This design relies on precise folds for the tongue lock and base hooks. Fine flutes fold crisply and lock securely. Heavy double-wall board will cause the small locking tabs to bind or tear unless the cutting die is explicitly widened.

Cutout purpose and sizing

Decide early if the top holes will be used for a retail peg, a plastic handle, or an internal product neck. The exact diameter and placement dictate how the lid balances weight.

Base load capacity

Evaluate whether the product weight exceeds the capacity of a friction-locked base. Physical drop testing helps confirm the floor strength before committing to a large run.

Production volume and tooling

The complex base hooks and top cutouts mean this carton is produced using a flatbed or rotary die-cutter. This production path makes sense for medium-to-large repeat runs where the initial setup is spread across a higher volume.

Adjusting the locks and display features

Tongue lock depth

The front locking tab can be extended for a tighter grip or shortened for easier consumer access, depending on whether transit security or easy reopening is the priority.

Base friction

The interlocking bottom hooks can be adjusted to snap together more tightly, though this means packers apply more force during assembly.

Hanging hole removal or resizing

If you only want the secure tongue lock without the retail hanging features, the cutouts can be removed from the cutting die entirely.

Board and packing details

Pre-breaking the score lines

Packers may need to pre-fold the small tongue lock hinge before inserting it. Forcing stiff corrugated board into the narrow front slit without pre-breaking can tear the tab.

Additional notes

Hand assembly rhythm

While the snap base is faster than taping, it still involves a manual 1-2-3 folding sequence. For fast-paced fulfillment lines, an automated crash-lock base may be worth evaluating.

Print surface and branding

The unbroken front and top panels provide excellent billboard space for retail graphics, as there is no packing tape to obscure the artwork.

FAQs

Route and shipping

Can this carton be shipped through the mail without an outer shipper?

The mechanical locks are designed for presentation and handling, not courier drops. Parcel shipping usually involves an outer master carton or a heavy-duty clear seal over the tongue lock to keep it closed on impact.

Packing labor

Does the snap bottom need tape or glue?

The base locks together entirely through friction. The only glue used is the side seam applied at the factory before the carton is delivered flat to your facility.

Board and finish

What board thickness is appropriate for the tongue lock?

Single-wall board or fine flutes fold cleanly. Thick double-wall board fights the fold, making the small tongue lock difficult to insert and prone to tearing.

Modifications

Can we remove the hanging holes from the design?

Yes. If you only want the secure tongue lock without the retail hanging features, the cutouts can be removed from the cutting die.

Product fit

How much weight can the snap bottom hold?

This depends heavily on the board grade and the exact dimensions of the base. It is built for light-to-medium retail goods. We suggest physical drop testing with your actual product before committing to a large run.

Packing labor

Do packers need special equipment to assemble this?

No equipment is needed. The carton pops open by hand, and the base flaps fold in a 1-2-3 sequence to lock the floor in place.

Print and finish

Can we print on the inside of the lid?

Yes, the inside of the lid and the tuck flap can be printed to enhance the unboxing experience, though this involves two-sided printing during production.

Route and shipping

How are these cartons delivered?

They are delivered flat with the side seam already glued. This maximizes pallet density and saves storage space before they are erected at the packing bench.
