EVC50021

Stackable Corrugated Paper Tray

The EVC50021 is a stackable corrugated tray designed for document sorting, office organization, and retail presentation of flat goods. It features an open, angled front for easy access and a built-in interlocking mechanism that allows multiple trays to stack securely without sliding.

Unlike standard bin boxes with raw cut edges, this tray uses a diagonal front fold to create a smooth, double-thick bevel. It assembles entirely by hand without glue or tape, making it an efficient, flat-delivered solution for internal sorting or shelf presentation.

Document Sorting and Retail Display

Document Sorting and Office Organization

The open front and interlocking stacking tabs make this an excellent alternative to plastic desk trays. It provides easy access to standard paper sizes while keeping stacks aligned.

Retail Presentation of Flat Goods

The folded front bevel hides the raw corrugated edge, offering a cleaner presentation for retail shelves. It works well for displaying flat merchandise, brochures, or lightweight packaged items.

Internal Kitting and Assembly Lines

For staging flat components or instructions on a packing line, these trays can be stacked to save bench space and easily broken down when no longer needed.

Mailroom and Literature Distribution

Useful for sorting incoming mail or organizing marketing literature for sales teams, keeping different categories separated but visible.

Internal Fulfillment and Kitting Environments

Internal Fulfillment and Kitting

Operations teams looking to organize workstations without investing in permanent plastic or metal bins often use these trays for temporary or changing workflows.

Retail Merchandising

Store managers needing temporary or seasonal shelf organizers that look professional but can be recycled after the promotion often choose this folded-edge design.

Office and Administrative Environments

Workplaces seeking recyclable, cost-effective desk organizers for high-volume document handling can deploy these trays across multiple departments.

Heavy Parts and Parcel Shipping

Heavy-Duty Parts Storage

Because the back wall is single-thick corrugated board, heavy metal parts or dense hardware may cause the back to buckle under a tall stack. For heavy industrial storage, a standard reinforced bin box is worth evaluating.

Parcel Shipping

This is an open-front tray, not a closed shipping container. If the items will be shipped through a courier network, an outer master carton or a fully enclosed mailer should be considered.

Board Thickness and Print Surface

Board Thickness and Flute Profile

E-flute is the recommended material. It provides enough rigidity for desktop use while allowing the diagonal front corners to fold cleanly. Thicker boards, like B-flute, need precise crease allowances to prevent the folds from binding.

Print and Surface Finishing

Because the inner side walls roll over 180 degrees during assembly, the outside print surface will be visible on the interior sides of the tray. This makes it highly suitable for two-sided branding using only a single-sided print run.

Stacking Height and Weight

Determine how many trays will be stacked and the expected weight per tray. This helps confirm if standard E-flute is sufficient or if a different board profile is necessary to prevent the bottom tray from buckling.

Delivery Form and Assembly Labor

These trays are delivered flat and assembled manually. Buyers should plan for the labor time needed to fold the trays before use, as they do not run through automated folder-gluers.

Front Access Angle and Stacking Clearance

Front Access Angle

The depth and angle of the front opening can be adjusted to expose more or less of the contents, depending on whether the priority is easy access or better retention of the stacked items.

Stacking Clearance

The width and height of the top stacking tab, along with the corresponding base slot, can be modified to ensure a snug fit based on the exact board thickness used.

Overall Tray Dimensions

Length, width, and height can be scaled to fit specific document sizes, brochures, or retail shelf depths.

Packing details

Manual Assembly and Flat Delivery

The tray is delivered flat and assembled manually. The process involves folding the back wall, rolling over the side walls to trap the front diagonal corners, and snapping the bottom tabs into the base slots.

Additional notes

Stacking weight limits

While the side walls are double-thick, the back wall is single-thick. Very heavy loads in the upper trays may cause the bottom tray's back wall to buckle. Physical testing is recommended for heavy paper stacks.

FAQs

How do these trays stack together?

The back wall features a top tab that points straight up. When you place another tray on top, this tab inserts into a pre-cut slot in the base of the upper tray, anchoring the stack and preventing lateral shifting.

Does the tray use glue or tape?

No. The tray assembles using friction locks. The inner side walls roll over and snap into slots in the base panel, trapping the dust flaps and holding the tray together securely.

What board thickness is recommended for this tray?

E-flute is highly recommended. It folds cleanly at the complex diagonal front corners. Thicker flutes can be used but need precise adjustments to the crease allowances to prevent the board from cracking or binding.

Can the inside of the tray be printed?

Yes. Because the side walls roll over 180 degrees, the exterior print surface naturally becomes the interior side wall. If you need the base and back wall printed inside, a two-sided print process is an option.

Can I ship products directly in this tray?

No. This is an open-front display and sorting tray. To ship goods, the loaded tray should be packed inside a closed master shipping carton.

Why is the front edge folded instead of just cut?

The diagonal fold at the front corners rolls the corrugated board inward. This hides the raw, fluted edge of the cardboard, creating a smooth, double-thick bevel that looks more professional on a desk or retail shelf.

How is the tray delivered?

The tray is delivered flat to save space and reduce transit volume. It is assembled manually at the point of use.

Will the back wall buckle under heavy weight?

The back wall is single-thick corrugated board. Very heavy loads in the upper trays may cause the bottom tray's back wall to buckle, so physical testing is recommended for heavy paper stacks.

Review your document sizes and stacking height requirements to finalize the tray dimensions and board profile.
