Abstract
A packaging for a food product configured to be easily openable includes a film substantially surrounding the food product and formed from a sheet having a first longitudinal side and a second longitudinal side, a seam formed by the first longitudinal side overlapping and bonding to the second longitudinal side, a tab extending beyond the seam from one of the first longitudinal side and the second longitudinal side, and at least one tear initiator provided in the film adjacent the tab, the at least one tear initiator defining a starting point for a tear path, the tear path extending generally perpendicularly from the seam

A packaging for a food product configured to be easily openable, the packaging comprising:
- a film substantially surrounding the food product and formed from a sheet having a first longitudinal side and a second longitudinal side;
- a seam formed by the first longitudinal side overlapping and bonding to the second longitudinal side;
- a tab extending beyond the seam from one of the first longitudinal side and the second longitudinal side;
- and
- at least one tear initiator provided in the film adjacent the tab, the at least one tear initiator defining a starting point for a tear path, the tear path extending generally perpendicularly from the seam.
A packaging for a food product, the packaging comprising:
- a film substantially surrounding the food product and formed from a sheet having a pair of longitudinal sides;
- a seam formed by the longitudinal sides overlapping and bonding to each other;
- a tab extending from one of the longitudinal sides beyond the seam;
- first and second tear initiators provided in the film and located on opposite sides of the tab;
- wherein the film is formulated to have directional tear properties so that a first tear path extending from the first tear initiator and a second tear path extending from the second tear initiator are formed when the packaging is opened by pulling on the tab, the first and second tear paths extending generally parallel to each other.
A method of forming a packaging for a food product, the method comprising:
- providing a film material;
- die cutting the film material to form two longitudinal sides, one of the longitudinal sides comprising a tab portion, the longitudinal sides being configured to be sealed together to form a seam;
- providing directional tear properties in the film material, the directional tear properties defining at least one tear path extending perpendicular to the seam.
