Thermoplastic films and bags

摘要

The present invention relates to a thermoplastic film having improved tear and puncture resistance. The thermoplastic film has a plurality of embossed regions that are comprised of a plurality of parallel, linear embosses. The plurality of embossed regions is arranged so that a straight line cannot traverse the thermoplastic film without intersecting at least one of the plurality of embossed regions. Certain embodiments further disclose an unembossed arrangement having at least three distinct segments that extend in three distinct directions.

主权项

1. An embossed pattern of thermoplastic film comprising:
a plurality of embossed regions embossed into the thermoplastic film, the plurality of embossed regions separated by a continuous, unembossed arrangement, each of the plurality of embossed regions comprising a set of parallel, linear embosses and each embossed region defined by a boundary with the continuous, unembossed arrangement, the continuous, unembossed arrangement comprising at least a plurality of first segments, a plurality of second segments, and a plurality of third segments, the plurality of first segments extending in a first direction, the plurality of second segments extending in a second direction, the plurality of third segments extending in a third direction, and the first, second, and third directions distinct from each other.
