As a result of my experi. mental? investigations in; relation to n this problem,

I; hare worked out-successful solutions thereofvv along several lines-as; f ollows:

Inaccordance with one modification of; my inventiom: I propose to pack the tacky, high molccular,, polymeric. material, such as butylrubher; in multil-w-all on multi'eplypaper bags-having fon-thejnner-i ply a; paper base laminate consist.- ing: of al layer of paper the; inner or exposed,

T-he purpose=of thB low-melting, wa-xa-like; adhesive interposed betweenthe paper baseeandrthee inner surfacelayer of the polymeric: layer; such as polyethylene; is temporarilyto :bond the latten to the iormerfol purposes of 'fahricating the bags and packing thebut'y-l rubber or similar sub-- stancestherein. Butyl rubber blocks-01' slabs are: ordinarily packed while at atemperaturesome--- Whattaboveroom temperature, for example; about; to F: After" being packed in multi-ply paper" bags; in acccrd'ance Withthe aforesaid modification of" my invention, the butylrubber will Iciecome"tenaciousl'ylionded to theainnenpoly" thene or equiyalentfiim of the" paper basel'ami nate;,while the elevatedtemperature'of the butyl rubber will" melt the wax like adhesiveof the laminate. sufficiently to: cause the latter tobleed into the paper. base; whereby the-polythcue-filmencased" butyl rubber" slab will; due to cold flow; strip, freely away" from, laminate withoutcarryin'g with it'any'adheri'ngpap'ero fibers, the paper base" acting like ablotter to absorb the adhesive during this; pr0cedure: The result-is a butyl rubber blockencased in the tenaciously adhering polythene film, this combihatibn... becoming thereupon loosely" packed in" theu multi -wall paper. bag; A's abovestated, thepolythene film has inherently a smooth unctuous the paper base of the surface, which slips or slides freely against the paper base from which it has thus been separated, and which at the same time wholly encases and thus prevents the tacky surface of the butyl rubber from contacting and adhering to the paper. Accordingly, for purposes of unpacking, the paper bag need only be slit and the filmencased butyl block dumped out.

In accordance with a second modification of the invention, and one which is alternative to that above described, the inner ply of the multiwall paper bag may again comprise a paper base laminate consisting, in this instance, of a paper base, over the inner surface of which is applied a slack-sized, clay coating, the clay coating being surfaced with a thin, relatively impervious film of a glue-like substance, such as casein, on top of which is applied a surface layer or coating composed of a synthetic hydrocarbon resin, which is compatible and miscible with the tacky, high molecular, polymeric material to be packed. Suitable synthetic resins for this inner surface layer of the laminate are, for example, polystyrene, stylene and polyethylene. As in the previous modification of the invention, the resin employed for the inner surface layer of the laminate must be sufficiently tough, flexible and expansible as not to crack under the cold-flow of the tacky polymeric material, and also such as to provide a smooth unctuous surface into n which the tacky material to be packed may be easily slipped.

The function of the clay coating interposed between the paper base and the inner resinous surface layer of the laminate, is temporarily to bond the latter to the former for purposes of employing the laminate in paper bag manufacture, and subsequently filling these bags with the tacky material, butyl rubber or the like, without rupturing the resinous film and without stripping the film prematurely from the paper base. The function of the impenetrable gluelike or casein surface film on the clay coating is to prevent the resinous inner surface layer when applied from penetrating through the clay coating, and thus forming a bond with the paper base, as otherwise the undesired paper fibers would permanently adhere to the resinous mner surface layer of the laminate.

When a tacky, high molecular, polymeric material, such as butyl rubber, is packed in a container in accordance with this modification of the invention, the tacky material will adhere to the inner resinous layer of the laminate, and will also stretch the same due to the cold-flow of the tacky material and, in so doing, W111 strip the resinous layer of the laminate away from its paper base, owing to the weak bondmg act on of the interposed clay coating, thereby effecting complete separation between the two. As a result of this cleavage in the clay coating, some of the clay coating will adhere to the resin film encasing the tacky material, while some will adhere to the paper base. The portions of the clay coating adhering to the resinous layer, however, as well as the resinous layer itself, are not injurious or deleterious substances as embodied 111 the end products into which the tacky material or butyl rubber is fabricated, the resmous layer because it is of itself a rubber-like substance miscible and compatible with the tacky material or butyl rubber, and the clay coating because it acts as a filler in the end products similar to the other fillers, such as carbon black, calc1um carbonate, etc., employed as filler materials in the manufacture of rubber goods.

When the butyl rubber or other tacky substance packed in the container has thus stripped the inner resinous layer away from the paper base of the laminate, the interposed clay coating material which adheres to the contiguous paper and resin layer surfaces of the thus cloven laminate, will act as a friction-minimizing medium to facilitate the slipping or sliding of the resin layer-encased tacky materal with respect to the paper base. Accordingly, the material may be unpacked by merely slitting the paper bag container and dumping the contents.

In accordance with still another modification of the invention, the inner or exposed surface of the-inner ply of a multi-wall paper bag, has applied thereto a slack-sized clay coating which is impregnated with an oil, preferably a synthetic oil, such as those marketed under the name Ucon oils, by Carbide 8: Carbon Chemicals Corp., for example, its Nos. LB-1l45 (high viscosity) and LB-385 (low viscosity) synthetic oils, or its 50-HB series, which are water soluble. Either type may be employed although I prefer to use the LB or water-insoluble type. The number after the LB designates the viscosity in Saybolt seconds at 100 F. These synthetic oils are polyalkylene-glycol derivatives, and their properties are described in an article entitled New Synthetic Lubricants by J. C. Kratzer, D. H. Green and D. B. Williams, appearing in The Petroleum Refiner for February 1946.

It has been found by employing this modification of the invention, that butylrubber blocks and the like may be easily slipped into the containers, whereupon the synthetic oil-impregnated clay coating serves as a weakly bonded separating and surfacing medium between the tacky material and the paper base. The surface of the tacky material, due to cold-flow, becomes completely coated with the oil-impregnated clay coating which adheres thereto, the cold-flow of the material serving also to cleave to the clay coating, and thus strip the so-coated material;

away from the paper base, in consequence of which the so-coated tacky material slides or slips easily with respect to the paper base, owing to the friction-minimizing action of the clay 'Particles adhering to the paper base and to the tacky material respectively. Thus, the contents may be easily removed by slitting the multi-wall bag and dumping the contents.

This modification of the invention may be improved upon by applying to the opposite or non-exposed surface of the inner paper ply of the bag, a thin, impervious film of an organic material, such as vinyl organasol, cellulose acetate or the like. The purpose of backing the inner paper ply with an impervious film of'this character is to prevent the oil of the oil-impregnated clay coating applied to the opposite surface thereof, from seeping or soaking through the outer paper plies of the bag, and thereby eliminating substantial quantities of the oil from the clay coating, in addition to weakening themulti-ply bag structure by the soaking action of the oil.

In accordance with a still further modification of the invention, the inner ply of the multi-wall bag again consists of a paper base laminate consisting of a thin film or layer of cellulose acetate or similar moisture impervious organic film, which is permanently glued to the paper base by means of a suitable interposed resinous or other suitable adhesive. It has been observed that when blocks of butyl rubber or similar tacky maaccesses thoughthebutyl rubber adheres somewhat to the-cellulose acetate film, neverthelessthe bag maybe slit and the bag material stripped away from the surface of the butyl rubber without tearing the acetate film, and hence without-causing any adherence of'the'film or paper to the butyl-rubber. The cellulose acetate or equivalent film acts as a tough, impervious and moisture-resisting shield between the butyl rubber and the paper, which doesnot tear or crack under the cold-fiowing action of the butyl rubber.

Vast improvement inthis modification of the invention is secured, in accordance with a further feature thereof, by the application to the exposed surface of the cellulose acetate layer, of

a light film or coating of an oil, preferably one.

ofthe water-insoluble synthetic oils. above referred to. Owing to the repellant action of such oils with respect to the surfaces of the butyl rubber, the tendency of the butyl rubber to adhere to the cellulose acetate layer is practically eliminated. Thus, the blocks of butyl rubbermay be'ea'sily slipped into multi-wall bags, in'accord-- ance with this modification of the invention, and the bags as easily unpacked by merely slitting and dumping the contents; The surface film of synthetic. oil isnotinjurious to the tacky material or to: products made therefrom, in addition to being present in negligible amount.

Referring now to the drawings:

Referring. now toFig. 1, there is illustrated. a:

multi-wall paper: bag Ill, made. up. of a multiplicity. of paper tubes, such as H, i2, i3 and [4,. disposed. one within another, these tubes being closed at the base by a sewn seam I5, the top being left open until the butyl-rubber other material. to be therein, whereupon the top is likewise closed by means of a sewn seamil.

block I 6 or Referring now to the modification of the in-- vention illustrated in Figs. 2 and 3, the inner paper ply Id of the multi-wall bag I2, l3, H5, haslaminated to its inner surface a thin layer H3 of polyethylene or equivalent, thislayer 18' being bonded to the paper layer llby means of an interposed layer is of a relatively low melting,

wax-like adhesive which melts at a temperature slightly below the temperature at which the butyl rubber block is is packed. As above stated,

butyl rubber ordinarily has a temperature of about 125 to 145 F; when packed, so that the wax-like adhesive should have a melting point slightly below this, for example, about to F.

The wax-like adhesive may consist, for example; of a microcrystalline wax, compounded Fig. 9 illustrates the appearance of the.-

the modification of the invenpackaged, has been placed with parafiin oil, for reducing the melting point as aforesaid, and containing, in addition, a tackifier, such for example as picolyte or a similar refined resin, for providing the necessary adhesion between the polythene film and the paper. A suitable microcrystalline wax is one composed of paraffin hydrocarbons, largely of the branched chain type, within the range of about C34H'io to C43Haa.

A suitable formula for such a wax-like adhesive is the following:

Per cent Paraffin oil 1-5 Picolyte or similar refined resin tackifier"- 1-5 Microcrystalline wax (M. P. 120-130 F.) Balance After the butyl rubber block l6 has been packaged in the multi-wall container I2, l3, I4, I8, IS, in the manner illustrated in Fig. 1, the cold-flow of the butyl rubber will cause this material to engage substantially the entire exposed surface area of the polythene layer l8, to which the butyl rubber tenaciously adheres. Likewise, the elevated temperature at which the butyl rubber is packed will melt the wax-like adhesive layer [9, causing the same to bleed or be absorbed into the paper plies I2, l3, l4, whereupon the butyl rubber block l6 encased in the adhering polythene surface layer [8 will strip away from the paper plies l2, [3, I4 in the manner illustrated in Fig. 3. Since, as above stated, the polythene film has a smooth unctuous surface, it will slide easily with respect to the inner paper ply l4, whereby upon slitting the paper plies, the butyl rubber and encasing polythene film may be easily dumped out.

Multi-ply pap-er bags, in accordance with Fig. 1, and employing the inner ply paper base laminate of Fig. 2, may be produced in the manner illustrated diagrammatically in Fig. 4. The paper base laminate may be produced by progressively feeding a continuous strip of the paper base material from a supply roll 2| in engagement with a doctor roll 22, which applies thereto the low melting, wax-like adhesing coating l9 from a transfer roll 23, which latter dips into a reservoir 24 of the adhesive material. At the same time, a continuous strip 25 of the polythene film is fed from a separate supply roll 26 and fed, together with the adhesive-coated paper strip 20, between a pair of compression rolls 2! for producing the laminated material 28, consisting of the paper base 20, the polythene film 25 and the interposed adhesive 19. The laminated material so formed is wound up in the form of a supply roll 29, and transferred thence, as at 30, to the entrance side of a bag tuber machine 3| of standard construction. The laminated material 28 is fed into the bag tuber fron roll 30 as the inner ply of the multi-wall bag the remaining plies, such as I2 and 13, of which are concurrently fed from paper supply rolls, such as 32, 33.

Referring now to Figs. 5 and 6, according tc this modification of the invention, the innei paper ply [4 of the multi-wall bag l2, l3, I4 has applied to its inner surface, a slack-sized double clay coating 34, as explained below, on the inner or exposed surface of which is sprayed or otherwise applied a thin impenetrable film of a glue-like substance, such as casein, upon which in turn is applied a resinous coating or layer 36 consisting of a synthetic resin, which is compatible and miscible with the tacky, high molecular, polymeric material being packaged, for ex ample, the butyl rubber block I6. As above stated, this resinous layer may consist, for example, of polystyrene, stylene or polyethylene.

The slack-sized clay double coating 34 comprises two separately applied clay coatings, a first coating applied directly to the surface of the paper ply, on which first clay coating is superimposed a second clay coating, to which latter the resinous coating or layer 36 is, in turn, applied. For the first clay coating applied directly to the paper ply, a coating in accordance with the following formula is suitable:

Formula I Per cent Talc 60-70 Bentonite 15-25 Defoamer (National Oil Products Co.

#1338: Nopco Defoamer) 3-4 Ammonium stearate 3-4 Casein sizing 5-7 Formula II Per cent Talc -60 Bentonite 15-20 Nopco defoamer (supra) 3-4 Ammonium stearate 3-4 Casein 12-20 This clay coating is likewise applied in aqueous suspension to the previously clay-coated paper in the manner illustrated in Fig. 4 by the elements 22-24 inc. and to the extent of about 15 to 25 pounds per ream of paper.

The interposed clay coating 34, comprising the two coatings aforesaid, forms a weak bonding layer between the resinous layer 36 and the inner ply l4, such that when the tacky material or butyl rubber block I6 is packaged in the container and subsequently cold-flows, the resinous layer 36 will tenaciously adhere thereto and cause the butyl rubber block and resin-encasing layer 36 to strip away from the paper ply [4 by cleavage of the interposed weak clay coating 34, in the manner illustrated in Fig. 6. As shown in this figure, following the cleavage, portions of the clay coating 34 adhere both to the paper ply l4 and to the resinous layer 36, as illustrated at 34c and 34b. This clay coating, being a frangible or powdery material, thereafter serves as a friction-minimizing medium between the inner paper ply and the resin layer to facilitate slippage of one with respect to the other, whereby, upon slitting the bag, the resin layer encased butyl rubber block may be easily removed by dumping. As above stated, the resinous layer and clay coating adhering to the butyl rubber produce no injurious effects in products made therefrom.

Referring now to Figs. 7 and 8, the inner paper ply l4 may have applied thereto a slack-sized, clay coating 38 in accordance with Formula I given above, which is thereupon impregnated with an oil, preferably a water-insoluble, synthetic oil of the character aforesaid, and the butyl rubber block IE or other tacky material packaged in th container as thus formed. Thereupon, the

r" l l .tackylmateriallt will split easilyawayirom the oil-impregnated clayncoati-ng 23.6, as illustrated in Fig-g8.

The butyl rubber, due to cold flow, subsequently strips awa from the bagby cleaviagzerof-the,double-;.clay;-coating as illus trated in Fig. 10. As above stated, the purpose of backing the inncr paper ply M with the i ipervious organic film la is to prevent the oil .a the clay coating 38 from seeping through into the outer paper plies, such as !'2, l 3.

Suitable adhesives for applying the cellulose acetate layer to the paper ply are lacquers, such as Du Ponts #4561, vinyl acetate adhesives, made by the Union Carbide or Bakelite companies; or adhesives made by National Oil Products C o. Also, in place of the cellulose acetate film, other equivalent materials may be employed such as vinyl butyral.
