A plastic shipping envelope, comprising: a first plastic sheet and a second plastic sheet, bonded to each other at a bottom edge of the shipping envelope and at side edges of the shipping envelope, wherein a chamber is present between inner sides of said first plastic sheet and second plastic sheets, and wherein an access opening is provided at a top side of the shipping envelope to allow one or more items to be inserted in and retrieved from said chamber, wherein the first sheet has a flap portion that, with respect to the second sheet, extends beyond a top edge of said second sheet, wherein the flap portion of said first sheet is provided with two vertically spaced apart strips (14A, 14B) of adhesive material, each arranged in a direction transverse to side edges (2, 3) of the sipping envelope, each strip of adhesive material (14A, 14B) being covered, at its side facing away from the flap portion, by a respective user-removable backing, and wherein the flap portion is provided with a perforated tear line, arranged in between said strips of adhesive material (14A, 14B), characterized, in that the shipping envelope further comprises: a re-sealable airtight seal with interlocking sealing strips, one of the interlocking sealing strips being arranged on the inside of the first sheet and the other of the interlocking sealing strips being arranged on the inside of the second sheet, both sealing strips being arranged near the access opening, in a direction transverse to the side edges (2, 3), and a one-way air valve, fluidly connecting the chamber of the shipping envelope to the outside, such that air can be vacated, when said chamber is closed by sealing said airtight seal, from the chamber to the outside, e.g. by compressing the envelope, and wherein the distance between the upper of the strips of adhesive material and the edge of the access opening is larger than the distance between the edge of the access opening and the re-sealable airtight seal, and the distance between the edge of the access opening and the perforated tear line is substantially equal to the distance between the edge of the access opening and the re-sealable airtight seal. a first plastic sheet and a second plastic sheet, bonded to each other at a bottom edge of the shipping envelope and at side edges of the shipping envelope, wherein a chamber is present between inner sides of said first plastic sheet and second plastic sheets, and wherein an access opening is provided at a top side of the shipping envelope to allow one or more items to be inserted in and retrieved from said chamber, wherein the first sheet has a flap portion that, with respect to the second sheet, extends beyond a top edge of said second sheet, wherein the flap portion of said first sheet is provided with two vertically spaced apart strips (14A, 14B) of adhesive material, each arranged in a direction transverse to side edges (2, 3) of the sipping envelope, each strip of adhesive material (14A, 14B) being covered, at its side facing away from the flap portion, by a respective user-removable backing, and wherein the flap portion is provided with a perforated tear line, arranged in between said strips of adhesive material (14A, 14B), characterized, in that the shipping envelope further comprises: a re-sealable airtight seal with interlocking sealing strips, one of the interlocking sealing strips being arranged on the inside of the first sheet and the other of the interlocking sealing strips being arranged on the inside of the second sheet, both sealing strips being arranged near the access opening, in a direction transverse to the side edges (2, 3), and a one-way air valve, fluidly connecting the chamber of the shipping envelope to the outside, such that air can be vacated, when said chamber is closed by sealing said airtight seal, from the chamber to the outside, e.g. by compressing the envelope, and a re-sealable airtight seal with interlocking sealing strips, one of the interlocking sealing strips being arranged on the inside of the first sheet and the other of the interlocking sealing strips being arranged on the inside of the second sheet, both sealing strips being arranged near the access opening, in a direction transverse to the side edges (2, 3), and a one-way air valve, fluidly connecting the chamber of the shipping envelope to the outside, such that air can be vacated, when said chamber is closed by sealing said airtight seal, from the chamber to the outside, e.g. by compressing the envelope, and wherein the distance between the upper of the strips of adhesive material and the edge of the access opening is larger than the distance between the edge of the access opening and the re-sealable airtight seal, and the distance between the edge of the access opening and the perforated tear line is substantially equal to the distance between the edge of the access opening and the re-sealable airtight seal.
