About this product

The EVC41122 is a one-piece corrugated mailer designed for presentation. It features a hinged lid with side cherry locks and double-thick side walls that roll over to lock into the base, creating a clean, sturdy tray for subscription goods, kits, and e-commerce shipments.

Because the side walls extend from the back panel rather than the base, this style creates a distinct folding sequence and a very clean front profile. This structure requires a wider flat blank than a common roll-end mailer, making it a deliberate choice for brands prioritizing the unboxing experience over maximum material density.

Common uses

  • Subscription boxes
  • Sales kits
  • Premium e-commerce

Presentation and E-Commerce Roles

Subscription Boxes

The hinged lid and cherry locks provide a deliberate, presentation-style opening that works well for curated monthly goods.

Premium E-Commerce

The double-wall sides protect contents, while the clean front wall elevates the perceived value of the shipment.

Sales and Presentation Kits

Shipped flat and assembled on demand, it serves as a sturdy tray for holding product samples, literature, or promotional assortments.

Influencer and PR Mailers

The clean front profile and built-in cherry locks create a deliberate unboxing sequence that suits high-value promotional seeding.

Who Uses This Mailer

Kitting and Fulfillment

Packers fold the side walls forward from the back panel, rolling them over the front corners. This manual sequence requires a bit more bench space than base-hinged mailers.

Retail and Shelf Storage

While primarily a shipping and presentation box, the flat base and rigid sides allow these to be stacked neatly in a stockroom or on a retail shelf before the final handover.

Manual Assembly Stations

Because the side walls must be held forward while rolling the top panels over, this tray relies entirely on hand packing and is not suited for automated erection.

When to Consider a Common Roll-End Mailer

High-Volume Material Efficiency

If minimizing the corrugated footprint is the primary goal, a common FEFCO 0427 mailer attaches the side walls to the base, allowing the flat blanks to nest more tightly on the corrugator sheet.

Automated Packing Lines

This tray relies on manual roll-over locks and tab seating. If the packing line uses automated folder-gluers or tray erectors, a machine-formed tray or glued crash-lock base is a better fit.

Heavy Industrial Shipping

While the double-wall sides are strong, the single-wall base and friction locks may not support dense, heavy industrial parts without additional reinforcement or a different box style.

Board, Flute, and Assembly Choices

Flute Profile

An E-flute provides crisp folds for the cherry locks and roll-over panels. Thicker boards like B-flute increase vertical strength but require wider lock holes and deeper creases to prevent the tabs from binding.

Print Placement

The roll-over side panels display the printed side on the interior of the tray, offering an opportunity for inside branding without requiring double-sided printing.

Parcel Sealing

While the cherry locks hold the lid closed for presentation, the box is unsealed. Parcel networks require a clear wafer seal, branded label, or shipping tape to secure the lid during transit.

Internal Clearance for Inserts

The roll-over side panels and the lid's dust flaps take up a small amount of interior space. Custom foam or corrugated inserts must be sized to accommodate these internal features.

Modifying the Lock and Closure

Cherry Lock Removal

If the side tabs on the front tuck flap cause too much friction during opening, they can be removed, leaving the lid to rely solely on the main front tuck.

Lock Hole Tolerances

The slots in the base that receive the roll-over tabs can be adjusted based on the exact board thickness to ensure a tight fit without tearing.

Dust Flap Angle and Length

The side dust flaps on the lid can be adjusted in length or angle to change how tightly they sit inside the rolled-over side walls.

Packing details

Blank Sprawl and Nesting

Because the side walls extend laterally from the back wall, the flat blank is exceptionally wide at the top. This cross shape affects how many boxes can be cut from a single sheet of corrugated board.

Friction Lock Variations

Friction Lock Variations

The depth of the base slots and the width of the roll-over tabs can be modified to increase or decrease the assembly friction.

Additional notes

Internal clearance for inserts

When sizing this box for custom foam or corrugated inserts, account for the roll-over side panels and the lid's dust flaps, which take up a small amount of interior space when fully assembled.

FAQs

How does the assembly differ from a traditional mailer?

In a traditional mailer, the side walls fold up from the base. In the EVC41122, the side walls are attached to the back panel. You fold the back wall up, wrap the side walls forward, and then roll them over the front corners to lock them into the base.

Does this box need tape for shipping?

Yes. While the tuck top and cherry locks keep the lid closed for presentation, parcel networks require an outer seal, such as shipping tape or a strong branded label, to keep the box closed during transit.

Can the inside of the box be printed?

Yes. Because the side walls roll over into the interior, the outside print surface naturally becomes the inside side-wall surface. Full interior printing requires double-sided printing, but the roll-over panels offer a built-in branding opportunity.

What board thickness is usually preferred for this tray?

Micro-flutes (like E-flute or F-flute) are usually preferred because they allow the cherry locks and roll-over tabs to fold crisply. Thicker boards can be used, but the lock holes and crease allowances must be adjusted to prevent the corrugated material from binding.

Is this tray suitable for heavy items?

The double-wall sides provide good stacking strength and side protection. However, the base is a single layer of corrugated board, so very heavy items may require an internal pad or insert to distribute the weight evenly.

Why does this style sometimes use more material than other mailers?

The flat blank has a wide cross shape because the side walls extend from the back panel. This shape can leave more offcut waste between blanks on the corrugator sheet compared to mailers where the side walls attach directly to the base.

How do the roll-over sides affect internal inserts?

The double-thick side walls and the lid's dust flaps take up a small amount of interior space when fully assembled. If you are designing custom foam or corrugated inserts, you must account for these internal clearances so the insert does not bind.

Can the cherry locks be removed?

Yes. If the side tabs on the front tuck flap cause too much friction during opening or if you prefer a simpler closure, they can be removed from the template. The lid will then rely entirely on the main front tuck flap.

Should we test the lock friction before a full run?

Yes. The security of the roll-over tabs and cherry locks depends heavily on the exact board thickness and die-cutting tolerances. Testing a physical sample ensures the tabs seat firmly without tearing the corrugated board.
