The Largest Polycell Corrugated Mailer We Carry

Polycell CRTP7 measures 360 x 485mm plus a 50mm flap, with a fluted paper lining under a white outer, and comes 50 to a carton.

Big flat things are awkward to post. A wall planner, a stack of A3 prints, a folded jacket or a large art book needs a bag with real width, and at 360 x 485mm this is the biggest Corrugated Mailer on our range. The paper lamination construction, as Polycell describe it, gives a papery hand feel and some body from the corrugated layer inside.

Photography of the range shows the lining as a ribbed paper layer and the flap closed by lifting a red printed liner off the adhesive. For prints that must arrive dead flat, slip a sheet of board in with them, because Polycell give no stiffness or crush figure for this bag.

See the smaller sizes in self seal shipping bags, everything else from Polycell, and packing cartons or bubble wrap for bulkier orders.
