Advanced, strong cardboard boxes for quick packaging and high-quality shipping. All ColomPac 151 boxes are self-sealing, and they have a quick and smooth instant bottom, making the product excellent for webshops. The tear open strip is easy and handy for the reciever. CP66/67 boxes are ideal for shipping fragile items. Their strong corner and edge protectors keep the products safe inside even when handled roughly. The optional FT140 stretch film tray insert can be added to the CP66/67 boxes when you need to send smartphones, tablets and laptops safely in the mail. The devices are placed under a stretched film, which keeps them in place and thus protects them from damage.
