Single-folded film
Some packaging machines have been designed for use with coils of plastic film in which the material is not wound as usual, but it is wound folded, that is, where in each coil appears at the same time the welded side or the non-sealing side from both faces, since the film is folded "V". Generally, this technology is used in extruded films, where the material fold is simply obtained by winding the film just extruded with "bubble" technology and trimmed laterally. Albertazzi has developed the technology for mono-bent laminated films, and in practice planar is created and wrapped in coils. We have the possibility of monofolding the plastic films up to 150 µm, keeping the sealing side outside or inside depending on the specific request.
