14 Claims

1. A packaging method comprising:

providing a bag comprising two main walls, having a mouth including an opening/closing means (30) for multiple successive openings and closings, a cleavable linking veil (40), located at a distance (D) from the opening/closing means (30), inside the bag in relation to said opening/closing means (30),

introducing contents (100) to be wrapped in the bag,

tightening of the bag to close it and applying tension to said contents (100), said veil (40) entering into contact with the contents (100) to avoid the application of stress on the opening/closing means (30),

providing free access to the contents (100) via said opening/closing means (30) after tearing of said cleavable linking veil,

enabling the bag to relax in a closed state as a result of the distance separating the veil (40) and the opening/closing means (30), wherein said cleavable linking veil (40) is a U sheet, and

fixing the U sheet to the bag by welding the U sheet to each of the two main walls of the bag at the distance from said opening/closing means (30).
