The Buyer’s Guide to Rigid Mailer Envelopes

At Salazar Packaging, we are one of the industry leaders in custom printed boxes for D2C ecommerce applications. Yet we also realize the importance of recognizing the right packaging solution for each potential project. This is why we also offer a variety of envelope products, including the Stayflats® Rigid Mailers, which have been an alternative solution to boxes for years, and are fast becoming one of our most popular products.


An Eco-Friendly and affordable Stock Solution

Stayflats® Rigid Mailers are available in stock at Globe Guard® Products for immediate purchase. More durable and stronger than alternative poly or bubble mailers, they’re ideal for papers, documents, photographs, brochures and many other products that may require protection from being bent or damaged during shipment, and they offer a tamper evident peel and seal adhesive closure strip.

You’ll find a selection of 13 sizes in both white and kraft, ranging from as small as 5-1/8 x 5-1/8 to as large as 22 x 27 with a low 1 case order minimum. Regardless of size, every case ships for a flat rate of $15.00 to anywhere in the continental USA.

Our Rigid Mailers are one of the most green products we offer, featuring 100% recycled content and are all 100% recyclable. Kraft mailers are also made from 95% post consumer waste, and white mailers from 35% PCW.

Boxes are often bulky and heavier by comparison, and can sometimes be tricky to assemble. Rigid Mailers offer an alternative that should both reduce shipping costs while minimizing storage space and saving time during fulfillment.


Custom Printing Has Many Benefits

At a low 2,500 minimum, Rigid Mailers are one of our most ideal products for custom printing because of the offset process which allows for a variety of designs, colors and aqueous coatings. While some 3 or more color designs and floodcoats do require a higher minimum for printing, plate costs are relatively low compared to other printed products and virtually anything can be achieved at higher volumes. We’ve been fortunate to print a variety of beautiful designs for many ecommerce and direct to consumer businesses over the years, as seen in the images below.
