  • Plastic net bag and label
    Patent number: 4196534
    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.
