Configuration resisting tear propagation in container sidewall

A container in which a slit-like opening is formed in a sidewall by tearing for gaining access to an interior of the container, the sidewall having:

• a primary weakened line extending a length between opposed ends thereof, tearing along the primary weakened line forming the slit-like opening in the sidewall;
• and
• two secondary weakened lines formed in said sidewall, each said secondary weakened line being spirally shaped and extending from said opposed ends of said primary weakened line, said secondary weakened lines inhibiting propagation of the tearing beyond said linear ends of said primary weakened line for maintenance of the slit-like opening.

A web of film used to make bags, said web comprising,

• a plurality of primary weakened lines each extending a predetermined length between opposed linear ends thereof, tearing along each said primary weakened line forming a slit-like opening in said web;
• and
• a plurality of pairs of secondary weakened lines, each said secondary weakened line of each said pair extending linearly in spaced, parallel relation to and in close proximity with a respective said linear end of a said primary weakened line and including only a portion thereof extending in overlapping relation to said linear end of said primary weekend line, said portion of each said secondary weakened line of said pair having a length substantially less than said predetermined length between said opposed ends thereof, each respective said pair secondary weakened lines inhibiting propagation of the tearing beyond said linear ends of a respective said primary weakened line for maintenance of the slit-like opening.
