Large Letter Cardboard Envelopes

A large letter size capacity cardboard mailer in an envelope style that can be used to pack and send online orders via Royal Mail. These sturdy cardboard envelopes are the correct size to send as a large letter, helping you to save on postage costs. The durable cardboard gives good corner protection and great puncture resistance. Envelope style mailers are super fast to pack. We believe in ultra fast packing for eCommerce stores. That’s why we’ve written a blog post on why fast packaging is so important for packing online orders. It’s all about volume. The more orders you can pack and send out the more money your eCommerce operation will make. Pack your e-commerce orders at high speed with our stock range of capacity ecommerce packaging mailers.

Large letter cardboard mailers have a high recycled material content for eco-friendly packing, and the envelope style makes these one of the most protective and cost effective mailers in our range. They are significantly more protective than bubble lined mailing bags, so if you are currently using jiffy bags our cardboard mailers are sure to help you pack better. A handy peel & seal closure strip and a tear open strip makes these pip envelopes very convenient. Like most of our ecommerce packaging range they are designed to be frustration free for your customer to receive and unpack.
