Thermoplastic bags comprising laminates having bonded protrusions and methods of making the same

A thermoplastic bag, comprising:

• first and second sidewalls;
• a bottom edge connecting the first and second sidewalls;
• a closure mechanism for selectively closing an opening of the thermoplastic bag;
• and
• a laminate with bonded protrusions, the laminate with bonded protrusions comprising:
• a first thermoplastic film incrementally bonded to a second thermoplastic film;
• a first strainable network formed in the first thermoplastic film, the first stainable network comprising a first plurality of protrusions;
• and
• a second strainable network formed in the second thermoplastic film, the second stainable network comprising a second plurality of protrusions;
• wherein:
• the second strainable network is configured and oriented as a mirrored version of the first strainable network;
• and
• protrusions of the first plurality of protrusions are bonded to protrusions of the second plurality of protrusions.

A method of forming thermoplastic bags with laminates having bonded protrusions comprising:

• creating a first strainable network of protrusions in a first thermoplastic film by advancing the first thermoplastic film through a first pair of patterning rolls;
• creating a second strainable network of protrusions in a second thermoplastic film by advancing the second thermoplastic film through a second pair of patterning rolls;
• bonding protrusions of the first strainable network to protrusions of the second strainable network by advancing the first and second thermoplastic films together through a first patterning roller of the first pair of patterning rolls and a second patterning roller of the second pair of patterning rolls;
• and
• forming the bonded first and second thermoplastic films into a bag.
