The modified fold adds a distinctive edge that stands out in the mailbox and guides the reader to your key message. Choose custom sizes with custom folds and panels to fit your campaign. Order wholesale from 100 units with free dieline and 3D mockup for approval before production. Ideal for marketing, corporate, and retail brands that want a branded mailer that mails ready, folds compact, and makes your message stand out from standard folds.

What is the minimum order for modified corner fold mailers?
The minimum is 100 units per size and design, and setup is free at that level. The same minimum applies to any size or format of modified corner fold mailers.
How quickly can modified corner fold mailers be produced?
Standard turnaround is 12 to 14 business days from proof approval, with 7 to 8 day expedited production available at a 25 percent rush rate. Transit time sits on top of that schedule for modified corner fold mailers.
Can I choose the exact size of the mailers?
Yes, any size. The dieline is drawn to your product’s exact measurements before tooling starts. Send the measurements and the dieline for modified corner fold mailers is confirmed before tooling starts.
Which print and finish options can I choose?
Full-colour CMYK and Pantone spot colour, with matte, gloss or soft-touch lamination, foil stamping and spot UV. Inside printing is available on modified corner fold mailers as well as the outer panels.
Can I see a mockup before ordering?
A free 3D mockup comes with every quote, showing the assembled pack before production. It shows the assembled modified corner fold mailers shape, not just a flat artwork file.
Can they double as a retail box?
Yes. Printed mailers with clean outer panels are used as both the shipping carton and the retail pack.
Which materials are used for modified corner fold mailers?
Common specifications use kraft, SBS and rigid board, with alternatives available if you need a different feel or strength. Tell us the product weight and finish and we will confirm the exact specification.
Will they survive shipping in the post?
Yes. Corrugated grades are built for postal handling, with double-wall options for heavier items.

Outstanding Performance all Around

When I do business with a company, I hold them to a simple standard: they need to excel at what they do, meet deadlines, and be people I actually enjoy working with. Sam at Alpha Global Packaging didn’t just meet two out of three, he knocked all three out of the park.

The custom display box was absolutely stunning. The quality was top-notch, with smooth, beautiful edges and a sturdy design that looked incredibly professional. I also ordered stickers and tissue paper, and everything was perfect down to the last detail.

Sam’s knowledge and communication was in a league of its own. From the moment I finalized my order, things moved immediately. He was responsive, proactive, and never left me wondering. Honestly, I wish every company I work with had a Sam.

When a shipping issue came up, the way this company handled it was beyond impressive. Rather than leaving me in limbo, Sam kept me updated every step of the way, and when the shipper couldn’t provide answers, he had everything reprinted and expedited without hesitation. It arrived quickly and was packaged so well it could withstand an apocalypse!

Alpha Global Packaging genuinely wants lifelong customers, and they’ve earned one in me. My business is just getting started, and I’m so grateful to have a company like this helping me shine on store shelves.

Nancy is a star! I work in very fast-paced events with restrictive turnaround times and she has made my life much easier with extremely fast responses, templates, and proofs. I'm already a return customer and will be back!

I am SO happy with my product!

I am SO happy with my product! I placed an order for a sample perfume box (100 of them) and they are tiny. I sent my branding and what I wanted on the front. Nancy was amazing. She was so patient with me as I described my particulars. I just received my package and I'm over the moon at how incredible they turned out! Exactly what I wanted. Pretty quick turnaround time and phenomenal work. Highly recommend and will definitely be using them again!

Trevor Green

Simple, smooth and efficient

We had a great experience working with Alpha Global Packaging from start to finish. Sam was incredibly easy to deal with throughout the entire process—clear communication, quick responses, and very helpful in guiding the creation and setup.

The final product turned out excellent. The print quality and overall finish looked really sharp and professional, exactly what we were hoping for. On top of that, the pricing was very competitive compared to other options we explored.

Everything was also delivered in a short timeframe, which will make a big difference for our launch. Overall, a smooth, efficient experience and we’d definitely work with them again.
