MOISTUREPROOF ARTICLE.
No Drawing.
This invention relates to a moisture-proof paper and a moisture proofing composition for paper, cloth, wood", etc.
As illustrative, paper has been commonly coated on one or both sides, or impregnated with parafiine with the idea ot-making the same moisture im ervious.
A arafline coatmg is comparatively stiff and brittle and cools with a rough, flaky surface, and suggests a-crystalline structure. A slight bend cracks the coating and permits the passage of moisture in the air even tho the coating may remain impervious to water.
Distinction. may, therefore, be made between a material which is moisture proof against water, but is not against moisture in the air, in a gaseous or vaporized guished item a liquid state. a 4
Repeated tests have proven conclusively that parafine paper even when slightly bent permits passage of moisture in the air. and
the latter being state as distinfolding of the paper permits the passage of of such moisture,
a relatively-large quantit ighly effective for so that the paper is not the, purpose designed.
It is quite necessar mercial use that para as bags or Wrappers should be bent and folded to fit the barrel or other container in practical comin which the material is to be shipped, or
must be bent or folded to fit the substance to be wrapped, and such bending and folding renders the paper ineffective to prevent the passage of all of the moisture of the air. I
It is, therefore, desirable to produce a paper that is substantially completely moisture-proof, not only as against liquid but as against the moisture in theair, and I have produced a bag, wrapper, or coated paper that is practically completely impervious to water, whether in liquid or gaseous state, and I have discovered and produced a saturating material which when applied to paper efiects thatresult. 4
moisture proofne paper when used Application filed January 4, 1922, Serial No. 526,992.
The paper so produced is comparatively flexible and may be bent and folded without. cracklng the saturating materiahand thereby permitting the passage of moisture whether liquid or gaseous.
The material may be less dense or more liquid than melted par-affine, and seems therefore, to have a greater pom-.tratiug capacity. I
The base of this coating composition is paraffin and with a suitable quantity'of paraflin, I mix preferably a quantity of a grease, as for instance petrolatum, for illustration, as sold under the trade-mark Vaseline or a mineral, animal or vegetable oil may be (ill substituted for the grease, for illustration,
paraflin oil, lard oil or cottonseed oil.
However, I at present eflicient the substance pctrolatum and therefore, I will specifically indicate an embodiment of my invention, in connection with that substance.
Preferably with eight parts of paraflin I mix three parts of petrolatum, and when paper is saturated with the composition so formed, 1t 18 substantially completely moisture-impervious as against moisture in the air as well as water.
The bag, paper, carton or other article or substance to be saturated should preferably be dipped ina body of the composition in liquid form as by that method a complete saturation with application of the composition to both sides of the article or material is effected. It is quite essential to my inprefer and find most vention that the composition be so applied,
as to effect a substantially complete saturation of the article or materialwith the composition and so that the composition fills all of the interstices of the material and renders the same proof against the passage of vapor thru it.
The bag, wrapper, paper or other material so saturated may be utilized for any purpose where it is desired to preventpassage of moisture, andis particularly useful for enclosing food products for the reason that the treating composition is practically odorless I claim: y i
