The manufacturing process of a bag made of bioplastic

The video content of the Biosack production video: Today we are taking you into the production of NaKu Biosacks - this is how a NaKu sack is made from bioplastics. In this video we show you the individual production steps. NaKu organic bags, organic carrier bags, organic freezer bags, organic waste bags, organic fresh storage bags, inlay bags for organic boxes made of organic plastic, organic clothing bags - production always happens in one way and we will show you that today.

It is very important that the natural plastic can be processed on the same machines as is the case with conventional plastic bags. To do this, the natural plastic must be in the form of granules, it must be free-flowing so that it can be fed into the machine very easily. The bioplastic granules are conveyed through a hose into the extruder via various funnels. Using different funnels so that the extruder is fed evenly.

The bioplastic material is then heated in the extruder. The extruder can be imagined as a screw through which the material is conveyed to the nozzles and heated at the same time.

The liquid material then comes out of the nozzle and is blown up freely from the inside. Here it is very important to get the same material thickness. The material is inflated to a force comparable to half the thickness of a human hair.

In the next step after the production of the bioplastic film or the bioplastic tube, the printing takes place. This can be done in a wide variety of printing processes, in one color but also in multiple colors. It is very important that the printing inks used are also compostable. We now have a printed hose made of bioplastic. In order to obtain a single bioplastic bag from this, this bioplastic tube is welded off piece by piece and handles are punched in.
