About this product

The EVF52064 is a heavy-duty, one-piece file box designed for document archiving, shelf storage, and collated retail kits. It features a hinged tuck lid and triple-thick side walls that lock together mechanically, eliminating the need for glue while providing excellent vertical rigidity.

Because it ships completely flat and relies on manual assembly, this package is efficient for storage before use. The built-in finger holes and clean, uninterrupted exterior make it a strong choice for both back-office organization and premium presentation.

Shelf Storage, Archiving, and Collated Kits

Long-Term Document Archiving

The triple-thick side walls and integrated finger holes are specifically designed for repeated pulling from shelves. The mechanical locks hold the box square even when filled with heavy paper files.

Corporate Onboarding and Welcome Kits

Without visible glue seams, the exterior offers an uninterrupted surface for branding. The hinged lid provides a clean unboxing experience for employee onboarding materials, training binders, or collated reports.

Educational Course Materials

For heavy textbooks or multi-part course binders, the rigid side walls protect the contents during handling. The tuck lid allows students to repeatedly open and close the box throughout a semester.

Back-Office Shelf Organization

The built-in finger holes make it easy to retrieve the box from high or deep shelving. The glue-free assembly means flat blanks can be stored densely and erected only as needed.

Office Supply, Education, and Corporate Fulfillment

Corporate Procurement Teams

Buyers managing internal office supplies benefit from a box that ships flat in dense pallets and can be erected on demand without tape or adhesive.

Educational and Training Distributors

Distributors shipping heavy paper goods can rely on the triple-thick side walls for containment, though an outer shipper is necessary for individual parcel delivery.

Marketing and Creative Agencies

Agencies designing premium presentation kits can use the entirely flat, unglued blank to print continuous graphics across all exterior panels without glue flap interruptions.

When to Consider Standard Tuck Cartons or Outer Shippers

High-Speed Automated Packing Lines

This box requires multi-step manual folding to engage the side locks. If your fulfillment center relies on automated folder-gluers or case erectors, a standard crash-lock or machine-erected carton is a better fit.

Direct Parcel Shipping

The tuck lid and mechanical side locks are designed for shelf storage and palletized freight. If shipping directly through a courier network, this box should be placed inside a corrugated outer shipper to prevent the locks from catching or opening during rough transit.

Board Caliper, Lock Clearances, and Assembly Labor

Board Thickness and Lock Clearances

The friction fit of the side tabs depends entirely on the board caliper. Heavy archival boards provide excellent stiffness but require precise creasing rules. If you switch to a lighter folding boxboard or a micro-flute corrugated, the lock slits and fold-over allowances must be recalculated to prevent tearing or a loose fit.

Manual Assembly Labor

Because the box uses no glue, the end user or fulfillment team must fold the inner panels, wrap the outer panels, and insert the locking tabs. This labor should be factored into your packing schedule, especially for high-quantity fulfillment.

Outer Shipping and Master Cartons

Since the mechanical locks and tuck lid are not designed for individual courier transit, you must plan for a secondary outer shipper if these boxes will be mailed directly to end users.

Print Surface and Branding

The unglued, flat-folding nature of this package means the entire exterior can be printed in a single pass. Decide early if you want to use this uninterrupted surface for full-coverage branding or organizational labeling.

Adjusting Finger Holes and Lid Clearances

Finger Hole Sizing and Placement

The circular cutouts on the side panels can be resized or removed entirely if shelf-pull functionality is not needed, which simplifies the die-cutting and stripping process.

Lid Hinge and Step Crease

The hinge where the lid meets the back wall includes a step crease to accommodate the thickness of the folded flaps. This can be adjusted based on your final material choice to ensure the lid closes flat without bowing.

Side Lock Tab Clearances

The length of the locking tabs and the width of the receiving slits can be modified. This ensures a secure friction fit whether you are using a dense solid bleached sulfate (SBS) or a thicker archival board.

Packing details

Flat Delivery and Storage Density

The one-piece unglued blank allows these boxes to be packed tightly on pallets. This maximizes warehouse space before use, making it practical to order larger quantities and assemble them only as needed.

Additional notes

Print Surface and Seams

Because the box is unglued and folds into shape, the exterior panels offer large, uninterrupted areas for branding, labeling, or organizational graphics without glue flaps getting in the way.

FAQs

Does this box require glue or tape to assemble?

No. The side walls use a mechanical tab-and-slit system that locks the panels together. The lid secures with a front tuck tongue, making the entire package adhesive-free.

Can this box be erected on automated machinery?

This package relies on manual assembly. The multi-step process of wrapping the outer side panels and inserting the locking tabs requires human dexterity.

What board materials fit this file box?

It is typically cut from heavy solid bleached sulfate (SBS) or specialized archival board to provide rigidity for shelf storage. Micro-flute corrugated can be used, but the locking tabs and fold clearances must be carefully adjusted to prevent the thicker material from crushing.

Will the side locks hold heavy documents securely?

The triple-thick side walls and locking tabs are designed to resist outward pressure from heavy paper files. However, the exact weight capacity depends on the board grade chosen and should be verified with a physical prototype.

Can I ship this box directly in the mail?

For courier or parcel networks, this box should be packed inside a corrugated outer shipper. The unglued side locks and tuck lid are vulnerable to catching or opening during rough individual transit.

How are these boxes delivered?

They are delivered completely flat. Because there are no glued seams, they stack very densely on pallets, reducing inbound freight costs and warehouse space.

Can the finger holes be removed from the design?

Yes. If you are using the box for presentation kits rather than shelf storage, the circular cutouts can be removed from the die-cut to provide a completely solid side wall.

Does the tuck lid stay closed if the box is tipped?

The front tuck tongue provides a friction fit for normal handling and shelf storage. However, it is not a locking seal, so heavy contents could push the lid open if the box is dropped or inverted.
