This invention relates to banded bread loaf
package and, more particularly articles such as
wrapped loaves of bread or the like which are
packaged by means of paper-like wrappers pro
vided with potentially adhesive coatings such as
heat-and-pressure sealable coatings and with
a band therearound.

customary to wrap- a relatively narrow band,
