These robust corrugated cardboard envelopes are ideal for sending flatter products such as license plates! The internal dimensions of this envelope are 140 x 590 millimeters (width x length). Note: This is based on the situation where the envelope is flat. The thicker the product you put in, the narrower the effective width becomes. This is because the sides 'come together' when the height needs to increase. The effective width of this envelope can vary between 140 and 95 millimeters. The maximum filling height is 50 millimeters. At that moment, the envelope will also have its smallest width-length ratio of 95 x 590 millimeters. 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 2500 pieces on a full pallet (= 100 bundles).
