Abstract
A packaging method includes the providing of a bag. A mouth of the bag may include an opening/closing for multiple successive openings and closings and a cleavable linking veil, located at a distance therefrom inside the bag in relation to the opening/closing. The method may also include introduction of contents to be wrapped in the bag and tightening of said bag in order to close it, with tension being applied to the contents. A veil may enter into contact with the contents to avoid the application of stress on the opening/closing, and guarantee free access to the contents via said opening/closing after tearing the cleavable linking veil. In one embodiment, free access to bag contents enables the bag to be relaxed in a closed state as a result of the distance (D) separating the veil and the opening/closing. The invention also relates to a packaging device and to bags thus obtained.
