AWOL (M) DIVER Box Liner | 18 x 18 x 16 in, Airtight, Fits a Medium Box

What an AWOL DIVER Box Liner Is For This is a sealed bag sized to drop inside a shipping carton rather than to be carried on its own. DL Wholesale give the size as 18 by 18 by 16 inches, which fills a medium box. That is roughly 85 litres of sealed volume. The construction is the DIVER specification: water tight and air tight rather than water repellent. Two top handles are fitted, so the liner can be lifted in and out while loaded. There are no shoulder straps, because the carton is the thing doing the carrying. The point of a liner is that the outer box takes the abuse and the inner bag keeps the seal. A duffle used the same way takes scuffs on its sealing surface, and a scuffed seal eventually leaks. It also means the outside of a shipment looks like a box and nothing more. Odour control is by seal rather than by adsorption. A carbon pad insert is sold on its own for AWOL bags if adsorption is wanted inside the seal. Getting a Sealed Inner Bag to Survive a Courier A sealed inner bag has one job on a courier network, and that is to stay closed. Couriers stack, drop and compress, and compression is what opens a zip that was not run fully home. Close the liner before the carton flaps go over, and check both ends of the track. Fill the void space in the box rather than in the bag. A liner packed tight puts tension on its own closure every time the carton is squeezed. Void fill between the liner and the carton wall takes that load instead. Keep the zipper track clean, because grit is the usual reason a seal starts to pass air. A wipe between uses is enough, and a silicone lubricant helps the gasket last. Think about pressure on air freight. A bag sealed at ground level expands in a hold, and an expanded bag presses on its own closure. Leaving a little slack in the liner handles that without any venting. Treated that way a liner outlasts the cartons it travels in, several times over. Key Features 18 x 18 x 16 inches: Sized to fill a medium shipping box, at roughly 85 litres.
