Abstract
An ultra-strong tear resistant, cut resistant, puncture resistant bag having a high shear strength or modulus is provided by weaving ribbons of flat polypropylene sheet into a bag. The bag is formed by weaving a cylindrically shaped object, cutting the object transversely and sealing up one end to form the bag. The physical properties of the ribbon-woven bag easily accommodate holding refuse including bricks, wood with nails, glass and other refuse in a lightweight disposable bag. In an alternative embodiment, the ribbon-woven bag is overlain with sheets laminated to the exterior of the bag to provide a fluid-tight container.
Claims20
An ultra strong, tear-resistant, puncture-resistant bag having a high tear strength, comprising:
- a ribbon-woven bag having crossed woven ribbons of flat polypropylene sheet devoid of low melting temperature bonding layers between the crossed ribbons, said bag formed in a cylinder and stitched at one end to complete the bag, wherein the stitch count for said bag is 100 per inch.
A method of removing refuse having sharp points or edges in an economical fashion, comprising the step of locating the refuse in a disposable ribbon-woven polypropylene bag devoid of bonding layers between the ribbon crossovers, the bonding layers having a melting point lower than that of the ribbon, the bag formed in a cylinder and stitched at one end to complete the bag, the bag having sufficient tear resistance, burst resistance and light enough weight to successfully retain the refuse without failure, wherein the stitch count for said bag is 100 per inch.
