These robust brown corrugated cardboard envelopes are ideal for sending flatter products or documents, for example! The internal dimensions of this envelope are 187 x 278 millimeters (width x length). Note: This is based on the situation where the envelope is flat. However, you can also unfold the envelope to a maximum filling height of 50 millimeters. This allows thicker products to be sent. This is achieved by folding the sides of the envelope 'together'. The disadvantage of this is that the internal available width and length decreases somewhat, in exchange for that extra filling height. At the maximum filling height of 50 millimeters, an effective interior space remains of 149 x 240 millimeters (width x length). If you are unsure whether your product fits in this envelope, you can always request a sample first! The envelopes are made of sturdy single-corrugated cardboard with a thickness of 1 millimeter. They also have a self-adhesive closing strip, so no tape is required to close the envelope. Finally, a tear strip makes it easy for the recipient to open the envelope with one simple action. The envelopes are fully recyclable and FSC certified. The envelopes are bundled per 25 pieces. There are 4800 pieces on a full pallet (= 192 bundles).
