Abstract

The present disclosure is concerned with chub packaging webs with improved puncture resistance suitable for use in chub packaging. The webs have a double waii partially laminated structure. The structure is conveniently formed by adhesively laminating two component films in a face to face configuration using a pattern of adhesive which leaves a substantial portion of the two facing surfaces unlaminated. Preferably, each of the component films comprise at least one layer of nylon and has a moisture content of greater than 1% by weight such that the double wall partially laminated web has a total energy impact absorption value of greater 0.59 foot-pound at −20° C. measured in accordance with ASTM D-7192 test method.
