Definitions

  • Rolls should be crisp at the outside and have a dry and neat crust while they are soft and not too dry at the inside. When rolls are left standing in the open air, they soon lose said properties and become completely dry; when they are kept in a container, the crust becomes soft and tough.
  • rolls can be kept fresh and crisp for about 8 hours :by filling them directly from the oven still hot, e.g. at a temperature of about 110 G, into an envelope described hereinbelow and then sealing said envelope.
  • FIG. 1 is a top plan view of a package arranged for receiving two rolls, still connected to another package
  • FIG. 2 is a side elevation of the package of FIG. 1.
  • a wrapper enveloping two rolls consists of a front wall of a transparent water vapor permeable cellulosic sheet sealed to a back wall of creped paper having an absorbent power defined hereinbelow.
  • the front wall is sealed to the back wall by means of an adhesive line or strip 4 previously applied to the back sheet.
  • Said adhesive strip is curved at the corners of the sheets. 5 designates a perforation for separating the filled envelopes.
  • the wrapper for the rolls must satisfy two conditions:
  • the transparent plastic front sheet must have high water vapor permeability, so as to allow ready escape of the water vapor given off by the hot rolls when they are filled from the oven into the envelopes and cool down therein to room temperature. If the water vapor cannot escape, the rolls do not assume the desired crispness.
  • Suitable plastics are celluose films, as they are available in commerce under the trademarks Cellophane and Transparit, particularly cellulose hydrate obtained by the viscose process and softened with a hydrophilic plastifier, such as glycerol.
  • the paper backing sheet must be made of a paper which has, in addition to high wet strength, for a weight per unit area of about 50 g./m. an absorption time below 20 seconds. Said adsorption time is a measure of the absorbing power and is determined by the time which passes until a paper sheet loosely placed upon colored water becomes wet and colored on its upper surface.
  • creped paper because with such paper the direct contact surface between rolls and paper is smaller than with smooth paper and because such paper provides, at the same width, for a larger surface than smooth paper.
  • the envelopes may be preformed to receive one, two, or more rolls or similar baked goods.
  • the mouth of the envelope after filling with the rolls, is heatsealed in suitable machines.
  • the envelopes may also be made in a packaging machine from continuously fed paper and plastics sheets and then immediately filled. In such case, it is of advantage to provide scored or perforated lines in the paper sheet forming the contiguous backs of the envelopes to assist the later separation of the individual packages.
  • the adhesive applied to the back sheet should form a curved line at least at one corner of the envelope. In this way, part of the paper sheet remains unsecured to the plastic cover and the free edge can be readily grasped for easy opening of the package.
  • a wrapper for keeping rolls and similar baked goods in fresh crisp condition comprising a transparent water vapor permeable cellulose front sheet marginally joined to a back sheet consisting of a paper having at a weight per unit area of about 50 g./m. an absorption time of less than 20 seconds.
  • a Wrapper assembly comprising a plurality of wrappers according to claim 1 suitable for receiving two rolls each and a perforation 'between adjoining wrappers.
