These brown carton envelopes are ideal for flat items which must not be bent or creased. The extra strong board used in manufacturing these cardboard envelopes makes this product perfect for all your postal needs. The 350 gsm micro-flute corrugated board is resistant and durable and will protect against tearing and perforation. Each cardboard envelope is securely sealed due to the peel-off adhesive strip on the closure flap, eliminating the need for tape. They also open with a convenient pull-tab.
Reinforced corners mean that these cardboard envelopes provide extra resistance to knocks and shocks in the post or in transit. Each cardboard envelope is adjustable in height up to 40 mm adapting to the height of your flat item. This makes these brown cardboard mailers ideal for posting CDs, DVDs, books, magazines, brochures, catalogues and calendars.
