Size B packaging for Paczkomat® InPost

Here you will find a complete selection of cardboard boxes designed to precisely fit the medium, size B locker of any Paczkomat® machine. Every box in this category meets the maximum external dimensions for size B shipments. The range covers sizes from 15.8 x 22 x 12 cm to 38 x 40 x 19 cm, making them suitable for a wide variety of medium-sized goods. We offer several construction types to match your specific packing needs. 

 
The regular slotted container (RSC) is the most common type of shipping box, featuring four flaps on the top and bottom that meet in the center. You assemble these boxes by folding the flaps and sealing the seams with packing tape. This straightforward design offers reliable protection for your items. Because we deliver these boxes flat-packed, they occupy minimal storage space in your office or warehouse, allowing you to keep a larger inventory on hand without clutter. You can order these versatile boxes in two variants: printed with the official InPost logo or as plain, unprinted boxes without any branding. Their standard construction makes them a dependable choice for securely shipping a diverse range of medium-sized products that fit within the Paczkomat size B locker.
 

 
If you need to pack items quickly, consider our boxes with an automatic, self-locking bottom. This design is engineered for speed and efficiency. To assemble, you simply press on the opposite corners of the flattened box, and the bottom automatically folds and locks securely into its final position. This eliminates the need to tape the bottom seam, saving you time on every package you prepare. After filling the box, you just need to seal the top flaps. This construction is an excellent option for businesses with high-volume shipping needs. Like our other models, these fast-assembly boxes are available with the InPost logo or in a plain, unprinted version.
 

 
For sending items that should not be folded, such as posters, architectural plans, or large documents, our mailing tubes are the correct choice. Made from durable corrugated cardboard, their rectangular tube shape provides structural rigidity that protects contents from being crushed or creased in transit. All mailing tubes in this section are sized to fit within the Paczkomat size B locker.
