Strong and durable flat mailers help ensure that your shipments arrive at their destination in the same shape they are shipped in. Having promotional documents, magazines, photographs, legal documents, certificates, and other documents arrive damaged, bent, or folded can hurt the reputation of your business and cause hassle and inconvenience. If a document arrives damaged, you will likely need to send out a replacement, which costs time and money. Plus, you’ll hurt the reputation of your business. Our strong, reinforced flat envelopes will protect your shipments from folds, bends, punctures, and other damage. They’re lightweight and easy to use, but also strong and tough. They get the job done. We have self-sealing options, kraft cardboard options, white envelopes, and much more. We understand the incredible importance of having reliable packaging. At your business, you don’t have the time to struggle with packaging and search for hours to find the right box or envelope for your shipment. You’d rather focus on running your business. And that’s why we’re here. We do the research for you. We find the right packaging for just about every situation and we stock a wide variety of different boxes, envelopes, and mailers so you have all the choices you need.

Clients use our strong flat envelopes to ship photographs and artwork to their customers, documents and contracts to business partners, diplomas and certificates to students and employees, promotional materials to potential partners, and so much more. The wide variety of items that need to be shipped require a wide variety of mailers and envelopes. We know that one size doesn’t always fit all, and that different applications call for different materials. That’s why we give our customers many options. It’s important to us that your business has the shipping and packaging materials that it needs to function smoothly and effectively.
