Definitions

  • a packaging material for use with automatically operated bundle packaging machines comprises a unilateral corrugated paper wound into a roll having a single exterior face and an interior corrugationwith a height below 2 /2 rnrn.
  • corrugated material having a corrugation height of between 1.3 up to 2.0 mm. having about 300 corrugations per square meter at a nominal corrugation height of 1.3 mm. and about 260 corrugations per square meter at nominal corrugation height of 1.5 mm.
  • the roll packaging material constructed in accordance with the invention provides corrugations on the side which will be normally on the interior of the package to provide a shock protection of the package and also permits the wrapping of the article in a clean symmetrical manner.
  • Various examples of the nature of the packing material which can be employed for the packaging of various goods are set forth herein,
  • corrugated paper board which is provided with a central corrugated layer and a cover sheet on each side of the corrugated layer
  • doublefaced corrugated papers or paper board corrugated papers or paper board.
  • bilateral corrugated papers have a corrugation height of about 5 mm. (so-called A-flute) and a corrugation height of about 3 mm. (so-called B-flute).
  • the end layers are also glued together to form so-called double corrugated papers.
  • Such board may be formed into cartons to provide a container for the placing of materials therein.
  • Bilateral corrugated paper board having a height of about 1.5 mm.
  • microcorrugation finest corrugation or as so-called E-fiute.
  • E-fiute Such corrugated paper is suited because of its stiffness only for producing cartons made by slitting, die-cutting, creasing, glueing, stitching, taping and the like.
  • packaging material is completely unsuitable for use in packaging an article to form a bundle on wrapping machinery.
  • the known single sided corrugated includes corrugations with a height of from 3 to 5 mm. but the sheets are so soft and ductile as to be unsuitable for the production ice of cartons. In addition, such papers are not suitable for the use with packaging machines, since the material cannot be cut or deformed easily particularly along lines transverse to the corrugation.
  • the diadvantages of the single face corrugated board construction can be overcome by using as packaging material a unilaterally covered corrugated paper which is wound up into a roll and which has corrugations of a height below 2.5 mm.
  • the number of corrugations per square meter is governed by the corrugation height and is greater when the corrugations are lower than when they are higher.
  • Such unilaterally covered corrugated papers can be used to particular advantage when the corrugation-height is between from about 1.3 up to 2 mm.
  • an object of the invention to provide an improved packaging material which compri es a roll of single sided corrugation having corrugations of a height less than 2.5 mm., the corrugation density being greater when the corrugation height is made lower.
  • a further object of the invention is to provide a roll of packaging material which includes a single face corrugated board having corrugations on the interior face of a wound roll which are of a height of from 1.3 up to 2 mm. and which includes from 300 corrugations per meter square at a height of around 1.3 mm. and about 260 corrugations per square meter at a nominal height of around 1.5 mm.
  • a further object of the invention is to provide a corrugated paper packaging material roll which provides a packaging material which may be manipulated easily and which provides a shock absorbing interior corrugated surface for the package which is to be wrapped therein.
  • FIG. 1 is a top perspective view of a roll of packaging material constructed in accordance with the invention.
  • FIG. 2 indicates a package wrapped with the packaging material of the invention.
  • the invention embodied therein comprises a roll A of corrugated board with a packing sheet B cut off from the roll.
  • the corrugated board includes a top or outer sheet 1 having corrugations 2 on the inside.
  • a package 3 which is wrapped with.
  • the sheet B of FIG. 1 to form the completed wrapped package which is shown with the cover in a partly opened condition.
  • the corrugations at the folding sides and edges extend substantially parallel to the axis of the package.
  • the solid lines 2a indicate the corrugations which are oriented on the interior of the package and the broken lines 2b indicate the course of the corrugations which are hidden on the interior of the completed package. These lateral lines are not shown in the upper panels of the carton in order that the upper portion of the view might appear clearer.
  • the unilateral corrugated paper of the invention may be wound up into rolls and can be used without the problems which would occur in the known packaging and bundling machines with the previously used paper. Thereby, the corrugated paper is wrapped cleanly and precisely around the merchandise to be packed by the machine with good results even when the wrapping takes place against the direction of the corrugations.
  • the unilateral corrugated paper it is advantageous for the unilateral corrugated paper to be wound up into a roll so that when the packaging machines pays out the material, the corrugations of the roll will be inside relative to the merchandise to be packed and the cover or outer sheet 1 will be on the outside.
  • the corrugations on the interior will protect the merchandise in the package against pressure and shock.
  • the exterior will be covered by the clean symmetrical outer sheet 1 with the folds being easy to make and without creating undue bulging.
  • Such packages may be stacked easily because of the smooth exterior formation.
  • a further advantage is that the shock resistance is increased by the manner in which the package is folded because of the several layers of corrugated board which will be presented, for example, at the top and side ends.
  • Example 1 Packaging material for chocolate goods, for instance, bundle packaging of chocolate bars weighing 100 grams each, or of 4 packages of chocolate candies weighing 250 grams each or of 4 packages of chocolate candies weighing 375 grams each.
  • the following materials are employed:
  • Cover of kraft paper 70 grams per square meter in weight.
  • Corrugations 1.3 mm. high having a weight of 90 grams (corrugation contraction factor about 30%).
  • Weight of the finished packaging material about 100 grams per square meter.
  • Example 2 Packaging material for 12 folded carton packages of baby food of around 400 grams:
  • Cover of kraft paper is about 80 grams per square meter in weight.
  • corrugations 1.3 mm. high with the weight of about 100 grams (contraction factor about 30 to 32%).
  • Weight of the finished packaging material about from 210 to 215 grams per square meter.
  • Example 3 Detergent wrapped in 3 single carrying packages at 3.2 kg.
  • Cover of the kraft paper weight about grams per square meter.
  • Corrugation 1.5 mm. high weight, grams (contraction factor about 34 to 35% Weight of the finished packaging material: about 220 to 222 grams per square meter.
  • Example 4 For magazines, periodicals and the like (the German postal regulations prescribe a maximum shipping weight of 12 kg. However, the material described sufiices up to about 15 kg. weight of contents).
  • Corrugation 1.5 mm. high. Weight: about grams (contraction factor about 34 to 35% Weight of the finished packaging material: about 275 grams per square meter.
  • Example 5 For beer cans and other canned goods, weight of contents from 10 to 12 kg.
  • Corrugation as described by customer from 1.3 to 1.5 mm. high.
  • Weight 115 grams (contraction factor about 30 to 32 or 34 to 35 respectively).
  • Weight of the finished packaging material about 260 or from 275 to 280 grams per square meter, respectively.
  • Example 6 For 24 beer cans at 0.33 liter contents:
  • Weight of the finished packaging material about 240 or about 265 grams per square meter, respectively.
  • the packaging materials are wound up into rolls and cut to the respectively desired widths and shipped to the customers as shown in the drawings.
  • packaging material comprising single-faced corrugated paper, wound into a roll and consisting of a single thin and flexibly fiat face sheet bonded to a corrugated sheet having corrugations extending transversely in parallel relation between opposite edges of said flat face sheet and extending uninterruptedly and continuously throughout their respective lengths; said corrugations having a height not exceeding 2.5 mm., and the number of corrugations per square meter increasing inversely with the height of the corrugations.
