Valentine mailer boxes are flat-shipped, self-locking corrugated boxes built to be the actual shipping container for a Valentine’s Day order — no separate outer carton needed. Crat Packaging manufactures these Valentine mailer boxes in our own US facility for e-commerce brands that want the unboxing moment to start the second the package hits the doorstep, not after it’s cut open.
Key Features of Our Valentine Mailer Boxes
- Self-locking construction — roll end tuck front (RETF) design tucks and locks without tape, so warehouse staff can fold and seal orders fast during the February rush.
- Ships flat, assembles instantly — mailer blanks store flat and pop into shape at the pack station, saving warehouse space compared to pre-formed boxes.
- Doubles as the shipping carton — corrugated strength means no secondary box, cutting packaging material and shipping weight.
- Interior and exterior printing — brand the outside for mailbox visibility and the inside lid for a “sent with love” reveal moment.
- Water-resistant finish options — gloss lamination adds protection against rain and snow during winter delivery.
- Free setup and die charges — no plate or die-cut fees, even for a one-time seasonal size.

Customization Options
Sizes and Styles
We cut these boxes to your product’s exact footprint. A tear-strip variant gives recipients a frustration-free opening; ear-lock tabs add extra security for heavier contents like books or multi-item bundles; a flat-profile version suits documents or apparel that doesn’t need much depth.
Materials
E-flute corrugated is the standard choice for lightweight items — cosmetics, jewelry, t-shirts — because it looks refined while still absorbing shipping impact. B-flute corrugated steps up crush resistance for heavier gift hampers. White corrugated stock gives red and pink inks maximum contrast for shelf and mailbox visibility.
Printing and Finishing
All-over exterior printing turns the box itself into a Valentine’s graphic that stands out in a stack of mail. Interior printing — a pattern of hearts or a printed message — is where most buyers get the strongest “wow” reaction from customers. Matte lamination reads premium; gloss lamination adds water resistance for winter shipping; soft-touch coating gives a velvety feel that signals a higher price point.
Add-ons
Fitted tissue or foam inserts keep fragile items like jewelry or glass from shifting in transit. A printed QR code on the interior lid can link to a playlist, video message, or return instructions — a small touch that fits the Valentine’s gifting occasion.

Frequently Asked Questions
What makes a mailer box different from a regular shipping box?
A mailer box is designed to be both the shipping container and the presentation box — it self-locks without tape and is printed inside and out, so no secondary outer carton is needed.
What material are Valentine mailer boxes made from?
Crat Packaging uses E-flute or B-flute corrugated board, chosen based on the weight and fragility of what’s shipping inside.
What is the minimum order quantity?
The minimum order is 100 units, with bulk pricing starting around $0.75 per unit depending on size, material, and finish.
Can I print on the inside of the box?
Yes. Interior printing is one of the most requested options — a printed pattern or message on the inside lid creates an unboxing moment when the box is opened.
How long does production take?
Standard turnaround is 10–15 business days after proof approval, with an 8-business-day expedited option for buyers ordering closer to Valentine’s Day.
Are there setup fees for a custom mailer size?
No. Plate and die-cut charges are free, including for one-off seasonal sizes.
