Automatic welding machines designed to weld, by thermal impulses, plastic handles on plastic bags or film.
The UNINOVAR SM and UNINOVAR SMV machines, designed to weld plastic handles on plastic bag, can weld also polyethylene film with thickness from 0.02mm to 0.50mm with a working width from 200mm to 600mm.
Thanks to the double welding bar (lower/upper) based on thermal impulse electronically controlled and to their robustness, efficency and speed, the machines of these series are ideal for big production and high quality.
The drive of the welding bars can be by means of a mechanical foot pedal (PM), or pneumatic (PN). In the PN version these machines permits the highest quality of the final product, thanks to the pneumatic close system, that assures perfect weld pressure and permits the regulation of the cooling stage.
The UNINOVAR SMV version, provided with different sized welding bars easily exchangeable, can weld different types of rigid handles on polyethylene bags, for the realization of boutique bags.
