Abstract
The present invention is directed to tamper-evident mesh material, methods of manufacture therefor, and tamper-evident bags manufactured therefrom. The tamper-evident mesh material of the present invention may be used, for example, in the manufacture of a variety of tamper-evident security bags for use in applications where it is desirable to detect any traces or evidence of tampering with or of unauthorized access to the contents of the bag.
Claims32
A tamper-evident mesh material comprising:
- a nonwoven mesh fabric, said mesh fabric comprising a plurality of strands, said plurality of strands comprising overlying strands and underlying strands, wherein said underlying strands comprise a visual property, and wherein said overlying strands are bonded to said underlying strands at a plurality of crossover points;
- and,
- a contrast layer, wherein said contrast layer is visually distinct from said visual property of said underlying strands, and wherein said contrast layer is disposed over at least a portion of each said overlying strand and each said underlying strand, and over said plurality of crossover points,
- wherein breakage of a bond between at least one of said overlying strands and at least one of said underlying strands at a crossover point of said plurality of crossover points exposes said visual property of said at least one underlying strand at said crossover point to indicate breakage of said bond.

A tamper-evident bag comprising:
- a first side, a second side, an opening and a bottom;
- at least a portion of at least one of said first side, said second side and said bottom formed from a tamper evident mesh material;
- said tamper evident mesh material comprising a nonwoven mesh fabric, said mesh fabric comprising a plurality of strands, said plurality of strands comprising overlying strands and underlying strands, wherein said underlying strands comprise a visual property, and wherein said overlying strands are bonded to said underlying strands at a plurality of crossover points;
- and,
- a contrast layer, wherein said contrast layer is visually distinct from said visual property of said underlying strands, and wherein said contrast layer is disposed over at least a portion of each said overlying strand and each said underlying strand, and over said plurality of crossover points,
- wherein breakage of a bond between at least one of said overlying strands and at least one of said underlying strands at a crossover point of said plurality of crossover points exposes said visual property of said at least one underlying strand at said crossover point to indicate breakage of said bond.
