SELF-SEALING WRAPPING MATERIAL i Original Filed Nov. 7, 1949 2 Sheets-Sheet 2 @MMM Patented Apr. 27, 1954 UNITED STATES PATENT OFFICE SELF-SEALING WRAPPING MATERIAL Bertram L. Trillich, Winnetka, Ill., assignor to The Munising'Paper Company, Chicago, Ill., a

corporation of Ohio 6 Claims.

This invention relates to a Wrapping material especially adapted for Wrapping small articles and more particularly to a quick-sealing, moisture-proof, wrapping paper for wrapping a comestible to maintain its moisture content. In its preferred aspects the invention relates to a quicksealing, moisture-vapor-proof Wrapping paper.

This application is a division of my copending application, Serial No. 125,9-73, filed November 7, 1949, now Patent No. 2,529,060.

The wrapping material of the present invention consists of a paper-thin flexible carrier sheet, preferably of paper, having a flexible coating of a moisture-proof material, preferably a moisturevapor-proof material, on one side thereof and on the other side a flexible coating or lm of a resinous self-adhering material which is substantially dry to the touch and substantially nontacky but which is cohesive even under light pressure, and yet which is for all practical purposes non-adhesive to any surface such as paper, cellophane, Wood, glass, metal, paint, rubber, etc., devoid of said material. The resinous self-adhering materials which may be used in accordance with the present invention are known materials and are usually termed cohesive, substantially non-adhesive materials. For convenience, these Vmaterials will be similarly referred to herein.

Any of such resinous self-adhering materials may be used in accordance with the present invention.

The combination of a flexible water-proof coating on one side of a flexible carrier sheet and of a cohesive, substantially non-adhesive coating or film on the other provides a wrapping material for foodstuffs having desired moisture-proof or moisture-vapor-proof properties and a versatility and ease of use not heretofore present in any of the prior art Wrapping materials, insofar as I am aware. The wrapping material of the present invention may be manipulated readily in sealing relationship about foodstuffs or dishes or other articles containing the same without the aid of heat or other extraneous expedients which entail skill and are inconvenient for the user.

In its preferred aspects the wrapping material of the present invention consists of a flexible, calendered paper sheet, one surface of which is coated with a exible film or coating of a wax and the other with a film or coating f a resinous cohesive, substantially non-adhesive material such as a nlm or coating of a plasticized polyvinyl acetate composition disclosed in Patent No. 2,371,001, granted March 6, 1945.

Any paper-thin, flexible carrier sheet which lends itself for use in Wrapping small articles may face penetration of the resinous cohesive, substantially non-adhesive material. Other papers such as hard sized papers may, of course, be used. With such hard sized papers it may be necessary to overcome the effect of this sizing by the addition to the resinous material of a surface active agent to reduce the surface tension of the resin and to increase the wetting and penetrating power thereof. Any suitable surface active agent may be used for this purpose. Examples of suitable surface active agents are sodium lauryl sulphate, sodium cetyl sulphate, the sodium salt of the dioctyl ester of sulfosuccinic acid (Aerosol OT), the sodium sulphate derivatives of 7-ethyl- 2-methyl-undecanol-4 (Tergitol 4) and 3, 9 diethyl tridecanol-5 (Tergitol 7), decyl benzine sodium sulfonate (Santomerse 5), and phenylpara-toluene sulfonate.

As pointed out above, any resinous cohesive, substantially non-adhesive material may be used in accordance with the present invention. Thus it may be a resinous cohesive material formed from co-polymers of polyvinyl acetate and polyvinyl chloride, polyvinyl acrylate, polyvinyl methacrylate, polyvinyl ethacrylate and like acrylates having from l to 5 carbon atoms in the alkyl group, polyvinyl ethers, polyvinyl ketcnes such as methyl vinyl ketone, polyvinyl alcohol, polyvinyl acetals such as formal, butyral, etc., and similar compounds containing a single ethylenic double bond, C:C or a mixture of such compounds. The amount of cohesive material applied to the carrier sheet may be varied widely, say from about 0.2 lb. to 2 lbs. (solids) per 144 sq. yds. of carrier sheet.

The following is a further example of a cohesive, substantially non-adhesive material which may be used in accordance with the present invention.

Parts by Weight Polyvinyl acrylate latex 100.0 Dibetanaphthyl p-phenylene diamine (antioxidant) 1.0

Any suitable wax or wax-like material such as paraffin wax, beeswax, montan Wax, carnauba wax, synthetic wax such as the high melting point coated Wrapping sheet may be wound on the roll with a liner material (not shown) to prevent the opposed cohesive surfaces from adhering to one another, as is well understood.

I claim:

1. As a new article of manufacture, a moistureproof sheet of self-sealing wrapping material adapted completely to encase an article and thereby seal the same against outside moisture, said article comprising a thin flexible paper sheet normally pervious to moisture, said sheet having on one surface thereof an exposed comparatively thin flexible wax film coating completely covering said surface and thereby imparting moistureproof properties thereto and on its other surface an exposed flexible film of a cohesive, substantially non-adhesive resin, said last mentioned film covering the complete said other surface of the sheet and being substantially dry and non-tacky and yieldingly self-adhering when portions thereof are brought into engagement, but being nonadhesive to such surfaces as wood, glass and metal, the said non-tacky self-adhering film cooperating with said wax coating in moistureproofing said paper sheet.
