Abstract
Abstract A packaging laminate suitable for use in the manufacture, for instance, of bags capable of packaging bulky cuts of meat containing sharp edged bones as prepared subsequent to butchering, comprising a face or outer layer of a polyamide such as nylon, an intermediate non-woven web of synthetic resin filaments, and an inner layer formed by a grease-resistant synthetic-resin film and the bags, pouches and wrappings prepared from such laminates. The web may be spun-bonded polyester, polypropylene or polyethylene. The innermost layer may be an ionomer or an ethylene/acrylic acid copolymer.
