High-strength slider for a reclosable bag

A slider for straddling relation with a profiled plastic zipper of a reclosable bag, said zipper having first and second interlocking profiles, said straddling slider closing and opening the interlocking profiles by movement along the zipper, comprising:

• a transverse support member;
• and
• a pair of side walls extending downward from opposing sides of said support member, said side walls forming respective first and second shoulders extending inwardly toward each other, said first and second shoulders including respective first and second innermost ends facing and contacting respective adjacent portions of the reclosable bag below the respective first and second interlocking profiles, said first and second innermost ends defining an S-shaped tortuous path therebetween, said adjacent portions of the reclosable bag passing through said S-shaped tortuous path, said first innermost end forming a first protruding portion jutting further inward toward the respective adjacent portion of the reclosable bag than a remainder of said first innermost end.
