Title
(EN) VACUUM SKIN PACKAGING APPARATUS AND PROCESS
(FR) APPAREIL ET PROCÉDÉ D'EMBALLAGE MOULANT SOUS VIDE
Abstract
(EN)
It is disclosed a vacuum skin packaging apparatus equipped with a cutting device. The apparatus comprises an arrangement for packaging products between a bottom thermoplastic web and a top thermoplastic web, wherein the top web forms a tight skin all around the products to be packed, thus sealing wherever the two webs contact each other. The cutting device comprises a laser source (LS) producing a laser beam (LB) at a first optical power and means (MR) for directing said laser beam at said first optical power towards the area where the two webs contact each other in a manner that the reflected laser beam (RLB) at said first optical power follows a predetermined path (CL) so that the two webs become cut and the products become packaged singularly.
(FR)
L'invention concerne un appareil d'emballage moulant sous vide équipé d'un dispositif coupant. L'appareil comprend un arrangement pour l'emballage de produits entre une bande thermoplastique de fond et une bande thermoplastique de dessus, où la bande de dessus forme un film moulant tout autour des produits à emballer, scellant ainsi partout où les deux bandes sont en contact l'une avec l'autre. Le dispositif coupant comprend une source laser (LS) produisant un faisceau laser (LB) à une première puissance optique et des moyens (MR) pour diriger ledit faisceau laser à la première puissance optique vers la zone où les deux bandes sont en contact l'une avec l'autre d'une manière telle que le faisceau laser réfléchi (RLB) à ladite première puissance optique suive un chemin prédéterminé (CL) afin que les deux bandes soient coupées et que les produits soient emballés individuellement.
