A single piece non-wrinkling wrapper for bars of soap is made from a lamina of sheets of a flexible plastic film and a water absorbent paper. The film and paper are superimposed and bonded together along their margins by bands of adhesive. The exposed surface of the paper sheet is coated with a cold seal cohesive along the margins in register with the adhesive bands. When wrapped around a bar of soap, the cohesive and adhesive fall in the back seal and end seal areas of the soap, thereby double wrapping the bar with the film and paper sheets and with an air space between the sheets which prevents or minimizes the wrinkling of the outer wrap. The wrappers may be made on a continuous basis from a wide web of film and paper that are bonded together along a grid-like pattern by means of bands of adhesive. The web is severed along the midpoints of the adhesive to form the individual wrappers.

A laminate comprising: a. a first rectangular sheet of thin flexible plastic material having a size and shape for wrapping around a selected object and having four marginal edges; b. a first band of adhesive deposited along the margins of the first sheet; c. a second sheet of thin flexible moisture absorbent material having four edges coterminous with the edges of said first sheet and superimposed on the first sheet and bonded thereto along a band line adjacent the margins thereof by means of the adhesive to form a nonadhered zone within the peripheral band line; and d. a second band of adhesive in the form of cold seal cohesive deposited around the margins of the exposed side of the second sheet above said first band, so that the laminate may be wrapped around a selected object and said second adhesive bands seal the edges of the object to thereby create a double layer of wrapping around the object so that wrinkling of said second sheet does not cause a corresponding wrinkling of said first sheet within said non-adhered zone with a layer of air between the two sheets.
