Abstract

Packaging sheet (1 ) intended for packaging a food product, in particular a cheese product, the packaging sheet (1 ) comprising: - an internal membrane (5) comprising at least one internal plastic layer (7) intended to be oriented towards the product to be packaged; and - a printable external surface (10), the external surface (10) being intended to be oriented away from the product to be packaged, characterized in that the or each internal plastic layer (7) has a plurality of microperforations (8, 9) arranged in a random fashion on the or each internal plastic layer (7) in such a manner that the air permeability of the internal membrane (5) is comprised between 20 mL/min Bendtsen and 50000 mL/min Bendtsen.

Abstract

A flexible envelope having a body initially scaled at one end in a zone designed to be opened, the body including at least two walls (26A, 26B) whereof the longitudinal edges are bound together along a longitudinal weld (14) extending over the height of the body, at least one of the walls (26A, 26B) extending outside the body beyond the longitudinal weld (14) to form a flap (36). The package has a weakened line (42) constituting an incipient tear formed on the flap (36) along the longitudinal weld (14), the weakened line (42) delimiting on the flap (36) a strip (43A) at least locally detachable from the package body and an adhesive (44) borne by a strip (43A), the adhesive (44) being designed to enable the strip to be subsequently bonded against the package outer surface.
