VACUUM SKIN PACKAGING APPARATUS AND PROCESS

摘要

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.
