Cardboard Envelopes

Cardboard envelopes are essential when mailing flat items that can’t be bent or creased, such as certificates or important documents. At Welco, we have a large range of cardboard envelopes in a selection of sizes, making them suitable for a range of items, including everything from magazines to contracts.

Made from corrugated board which is tear-resistant and durable, and with reinforced corners which provides extra resistance to knocks and shocks, our cardboard envelopes offer superb protection for items in the postal service. Additionally, they’re easy to seal due to an adhesive strip which eliminates the need for packing tape, and they also feature a pull tab, making them simple to open too. For more packaging supplies, browse our selection of cardboard boxes.
