Abstract

Abstract A bag including a bag body of net fabric formed by circular knitting from thermoplastic resin monofilament yarns, and a label of thermoplastic resin film affixed to the outer side of the bag body by heat and pressure at specified areas. The label is thermally adhered to the bag body by melting substantially the entire thickness thereof, and partially melting the monofilament yarns on the outer side of the bag body facing the label. The label is thus adhered to the bag with a high degree of stability, thereby assuring that it will not separate from the monofilament yarns. Preferably, the bag body is made from a circular knit fabric in which the number of crosswise yarns is smaller than the number of lengthwise yarns to provide a reduced number of courses per unit length of the fabric, thereby rendering the bag more stretchable crosswise than lengthwise, and which further contains a single or plurality of straight monofilament yarns extending crosswise ever several courses so that the lengthwise and crosswise stretch of the bag can be minimized when the bag contains vegetables, such as onions. A method of making the bag is also disclosed.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 99 words
A tubular net bag having a label affixed thereto comprising: a. a bag body of tubular net fabric formed by circular knitting a plurality of thermoplastic resin monofilament yarns having a smaller number of crosswise yarns than the number of lengthwise yarns to provide a greater crosswise stretchability to said bag compared to lengthwise stretchability, b. at least one straight thermoplastic resin monofilament yarn in said tubular net fabric extending crosswise therethrough said tubular net fabric every several courses to limit crosswise stretching of said bag; and c. a thermoplastic film indicia means integrally affixed with said bag body.
Claim 2
Dependent Claim 99 words
A tubular net bag having a label affixed thereto comprising: a. a bag body of tubular net fabric formed by circular knitting a plurality of thermoplastic resin monofilament yarns having a smaller number of crosswise yarns than the number of lengthwise yarns to provide a greater crosswise stretchability to said bag compared to lengthwise stretchability, b. at least one straight thermoplastic resin monofilament yarn in said tubular net fabric extending crosswise therethrough said tubular net fabric every several courses to limit crosswise stretching of said bag; and c. a thermoplastic film indicia means integrally affixed with said bag body.
Claim 3
Dependent Claim 49 words
A tubular net bag as claimed in claim 1 wherein said tubular net fabric having between 10 to 30 percent less crosswise yarns in number to the lengthwise yarns, and said straight thermoplastic resin filament yarns extending crosswise in said tubular net fabric being spaced about 4 millimeters apart.
