High performance machine for the production of bags with side seal flexible handle, from suitable LDPE polyethylene film with a mix percentage of up to 30% LLDPE.
Max bag height without flexible handle : max 700mm
Bag height : max : 600mm + bottom folding
Bag width (length of feed) : 300-750mm
Height of flexible handle : max 80mm
Mechanical output, without film : max 150 strokes/min
Web speed max : 70 m/min
Material type and thickness :
HDPE : 2 x 18-40 microns**
LDPE (with max 30% LLDPE) : 2x40-80 microns** - 4x40-60 microns**
** : welding bar radius required.
The machine can work all these thicknesses: 2 x are two layers of plastic (front and back of the bag) and 4 x are four layers (when you do bottom folding on the bag, weld 4 layers). Some will be more optimal than others depending on the lip radius of the welding rod which is usually 1.0 mm to 1.2 mm. For example, if you want to weld polypropylene, the radius would be approx. 0.3 mm; the one that the machine currently has is suitable for the materials and thicknesses indicated.

The machine has been modified to also make plastic sachets, although it would be sold together with all its loop equipment.
To convert it back to loop, the buyer would only need to lengthen the machine bed again.
Although not shown in the video, there is a separate robotic pick-up table, which is included, for the loop bag product.
So, in summary, both products can be produced with the machine.
