ABSTRACT:
Disclosed is an apparatus for manufacturing, through a vacuum skin packaging (VSP) method, an easy-to-open package provided with a device for initiating the opening thereof. The apparatus includes a sealing station (115) wherein a top web (113) is sealed to a bottom web (104) in a first area (A) all around a product (P) arranged on the bottom web by providing heat and vacuum in a fundamentally closed chamber. The apparatus further includes a local sealing inhibition unit (130) including at least one removable local sealing inhibition tool (150) for inhibiting the sealing between the top and bottom webs in at least a second area (B). A method is also disclosed including the step of inhibiting the sealing between the top and bottom webs by arranging at least one removable local sealing inhibition tool between the top and bottom webs in at least a second area.
