Abstract
The present invention relates to a thermoplastic bag having enhanced capacity without significantly compromising dart impact properties. The thermoplastic bag has an area of induced elasticity that provides enhanced capacity, the area of induced elasticity generally surrounded by an area lacking induced elasticity.
Claims18
A thermoplastic bag comprising:
- a first panel and a second panel, the first panel and the second panel joined along a first side edge, a second side edge, and a bottom edge,
- the first panel having a first area of induced elasticity defined in the first panel with an area lacking induced elasticity surrounding the area of induced elasticity,
- the first area of induced elasticity does not extend to the first side edge, the second side edge, nor the bottom edge of the first panel,
- the first area of induced elasticity defining a perimeter, the perimeter consisting of an ellipse, and
- the first area of induced elasticity covers between 10% and 30% of the first panel.
