Tear-off display boxes are becoming more and more popular for stand-up pouches (doypacks). This packaging format requires pouches to be packed standing up in a box. The box has a die-cut line around its body, which enables it to be separated into upper and lower parts. Discard the upper part and keep the lower part together with the pouches as a display. The box can be RSC, lock-bottom or wrap-around type. Calmus Machinery is one of the few manufacturers in China that can provide comprehensive case packing solutions for stand-up pouches.
RSC Boxes
RSC boxes are an efficient packaging option for stand-up pouches because they can contain multiple rows of pouches. It is more organized and safer to pack pouches standing up with cardboard dividers between rows. We have both split and monoblock case packers as options.
Lock-Bottom Boxes
Currently, the two typical types of lock-bottom boxes are auto-lock and snap-lock. Many manufacturers start with auto-lock bottom boxes for their pouch packaging because they are easily formed manually. To upgrade to automation, we suggest switching to wrap-around boxes because they are much stronger and can protect your pouch products better. However, we can provide case packers that handle both auto-lock and snap-lock bottom boxes if you do not want to change your existing boxes.
Wrap-Around Boxes
Currently more and more companies choose or switch to using wrap-around boxes to pack their pouch products due to their superior structural strength and lower material costs. Besides, wrap-around case packers are optimal for high speed. Our wrap-around case packer can handle up to 15 boxes per minute. The machine can pack infeed pouches from two standard Gualapak filling machines by combining two of our pouch collating lines, provided that one box contains 12 or more pouches.
Pouch Collator
Pouch collating is necessary before case packing. A collator organizes pouches into layers one at a time, stacks them with interlayer partition boards if more than one row in a case is required, and delivers them to the loading funnel, where the pouches are inserted into the formed case. Collators are a specialty product of Calmus Machinery. They are widely used with our packaging machines for instant ramen packets, sanitary pads, and diapers.
Pouch Unscrambler
Before entering the collating stage, all stand-up pouches must be on the conveyor one after another, with their heads all facing the same direction. But what if they come out of the upstream equipment in a disorganized manner? Calmus Machinery provides pouch unscramblers (also called pouch sorters by some) that can unscramble disorganized pouches and convey them one after another. Through visual recognition and rotation, they can then orient all stand-up pouches with their heads facing the same direction, and even flip them to ensure the same side of all pouches faces up.
