Abstract
One embodiment of a wrapping film comprises a polymer film having, on at least one surface thereof, at least one sealing area comprising at least one varnished area; and a plurality of individual unvarnished areas; wherein, within the sealing area, the area ratio of the unvarnished areas to the varnished area (PV:V) is ≦1; and wherein, within the sealing area, the largest individual unvarnished area is ≦30 mm2. Other embodiments are described.
Claims14
A wrapping film, comprising:
- a polymer film having, on at least one surface thereof, at least one sealing area comprising:
- at least one varnished area;
- and
- a plurality of individual unvarnished areas;
- wherein, within the sealing area, the area ratio of the unvarnished areas to the varnished area (PV:V) is ≦1;
- and wherein, within the sealing area, the largest individual unvarnished area is ≦30 mm2.
A method for making a wrapping film, comprising:
- forming, on at least one surface of a polymer film, a sealing area comprising:
- at least one varnished area;
- and
- a plurality of individual unvarnished areas;
- wherein, within the sealing area, the area ratio of the unvarnished areas to the varnished area (PV:V) is ≦1;
- and wherein, within the sealing area, the largest individual unvarnished area is ≦30 mm2.
A method for making a wrapping film, comprising:
- forming, on at least one surface of a polymer film, a sealing area comprising:
- at least one varnished area;
- and
- a plurality of individual unvarnished areas;
- and contacting at least a portion of the polymer film with the ream of paper;
- wherein, within the sealing area, the area ratio of the unvarnished areas to the varnished area (PV:V) is ≦1;
- and wherein, within the sealing area, the largest individual unvarnished area is ≦30 mm2.
A method for wrapping an article, comprising:
- forming, on at least one surface of a polymer film, a sealing area comprising:
- at least one varnished area;
- and
- a plurality of individual unvarnished areas;
- contacting the surface with a second surface of the polymer film;
- and
- applying energy to at least one of the unvarnished areas to form a peelable bond between the surfaces within the sealing area;
- wherein, within the sealing area, the area ratio of the unvarnished areas to the varnished area (PV:V) is ≦1;
- and wherein, within the sealing area, the largest individual unvarnished area is ≦30 mm2.
A wrapped article, comprising:
- an article wrapped with a polymer film having, on at least one surface thereof, at least one peelable bond comprising:
- at least one varnished, unbonded area;
- and
- a plurality of individual bonded areas;
- wherein, within the peelable bond, the area ratio of the bonded areas to the varnished, unbonded area (BA:VUB) is ≦1;
- and wherein, within the peelable bond, the largest individual bonded area is ≦30 mm2.
A method for wrapping an article, comprising:
- contacting an article with a polymer film;
- contacting a first surface of the polymer film with a second surface of the polymer film;
- and
- applying energy to at least a portion of the surfaces to form a peelable bond between the surfaces, the peelable bond comprising:
- an unbonded area;
- and
- a plurality of individual bonded areas in the unbonded area;
- wherein, within the peelable bond, the area ratio of the bonded areas to the unbonded area (BA:UB) is ≦1;
- and wherein, within the peelable bond, the largest individual bonded area is ≦30 mm2.
A wrapped article, comprising:
- an article wrapped with a polymer film having, on at least one surface thereof, at least one peelable bond comprising:
- at least one unbonded area;
- and
- a plurality of individual bonded areas;
- wherein, within the peelable bond, the area ratio of the bonded areas to the unbonded area (BA:UB) is ≦1;
- and wherein, within the peelable bond, the largest individual bonded area is ≦30 mm2.
