ABSTRACT:
The process comprises the steps of storing a non-heat-shrinkable handle tape (15), including consecutive stripes (MA) each having a non-adhesive central portion and adhesive end portions, applying the handle tape (15) to the film (P) while this is moving along a packing machine (M) before being wound and heat-shrinked around load (F), causing the handle tape (15) be pulled by the moving film (P) by having the handle tape (15) adhering to the film (P), finally cutting the handle tape (15) separating a stripe (MA) therefrom, adhering on the film (P). Stripe (MA), applied to film (P) before this is wound and heat-shrinked around load (F), forms a handle after heat-shrinking. The apparatus (1) to perform such a process comprises a feeding unit (2), a storing unit (3) and an applying unit (4). (FIG. 1)
