Re-closable paper-based package

A bag comprising:

• a first side sheet (20) having a pair of first side sheet transverse edges (70) and a first side sheet interior facing surface (23), wherein said first side sheet comprises an exteriorly oriented first pivotable flange (22) that is distal to a first folded portion (26) of said first side sheet and said first folded portion comprises a plurality of first panels (28) in which said first side sheet interior facing surface of said first panels are bonded to one another;
• a second side sheet (30) opposite said first side sheet and having a second side sheet interior facing surface (33) facing said first side sheet interior facing surface, wherein said second side sheet is connected with said first side sheet across a bottom (60) of said bag and has a pair of second side sheet transverse edges (100), wherein each said first side sheet transverse edge is joined to an opposing second side sheet transverse edge, wherein said second side sheet comprises an interiorly oriented second pivotable flange (32) that is distal to a second folded portion (36) of said second side sheet and said second folded portion comprises a plurality of second panels (38) in which said second side sheet interior facing surface of said second panels are bonded to one another;
• and
• a repositionable pressure sensitive adhesive (150) that releasably engages said first pivotable flange and said second pivotable flange;
• wherein said first side sheet and said second side sheet are each more than 80% by weight paper;
• wherein said bag contains a cumulative weight of articles;
• wherein said repositionable pressure sensitive adhesive has a load at failure according to ASTM D3165-07(2014);
• wherein said first pivotable flange is releasably engaged with said second pivotable flange by said repositionable pressure sensitive adhesive over a release zone having a release area, wherein said load at failure according to ASTM D3165-07(2014) multiplied by said release area is from about 2 to about 500 times greater than said cumulative weight of said articles.
