Description
Patented Nov. 20, 195i METHOD OF COATING GLASSINE Garrett H. Peters, Rhinelander, Wis., assignor to Rhinelander Paper Company,
Rhinelander,
Wis., a corporation of Wisconsin No Drawing. Application November 12, 1947, Serial No. 785,521
5 Claims. (Cl. 117-7 6) The present invention relates to a methodof coating paper, and more particularly, to a method of forming an adherent coating of a synthetic lacquer on glassine.
Glassine is a relatively transparent, greaseproof paper, formed of well hydrated cellulosic fibers, that has been s uper-calendered. Since glassine paper is inherently brittle, it is customary to plasticize glassine in order that it may be used satisfactorily in automatic wrapping machines. It has also been customary to coat glassine with wax in order to impart moisture-proofness and heat-sealing properties thereto. How ever, wax alone does not give entirely satisfactory heat-sealing properties.
It has therefore been proposed ,to employ thermoplastic resinsv for heat-sealing purposes. However, due to lack of adhesion between glas sine and certain lacquers, for example thermoplastic resins, such as vinyl polymers and various rubber compositions, this proposal has not thus far gone into extensive commercial use. These lacquer films aretoo easily stripped from the glassine base to make satisfactory coated products.
The present invention provides a method whereby an adherent coating of synthetic'lacquer may be applied to glassine or similar papers. The improved results of the method of the present invention are obtained by a pre-treatment of the glassine with an aqueous solution of a rl b e eni ls lt. Preferab Salts are employed which may be mixed with the plasticizers for joint application to the web on. the paper machine. The aqueous solution of the salts and of the plasticizers may suitably be applied to the web by means of a'size press located between sections of the driers. Thus, it is not necessary to "provide a separate dampener or other means for applying the aqueous solution to the paper. Alternatively, prior to the supercalendering step, the machine finished-greaseproof paper may be passed through a dampener containing an aqueous solution of the salt. The super-calendered and finished glassine is then passed through suitable coating apparatus, such as a conventional roller coating machine, by
means of whichthe synthetic lacquerniay be use in the process of the present invention. The
alkali metal and ammonium salts of such polyprotic acids as carbonic acid, orthophosphoric' acid, pyrophosphoric acid, metasilicic acid, orthosilicic acid and mixtures of silicic acids may be employed in the present invention. I have invention, including vinyl resins, such as the copolymers of vinyl acetate and vinyl chloride, cyclized rubbers, and chlorinated rubbers.
, The coated product obtained by the use of the present invention has enhanced transparency in comparison with glassine itself, and the added advantages of high moisture resistance, of ability to heat seal at relatively low temperature's, and of improved flexibility. These desirable characteristics are obtained along with a strong adherence of the coating film to the glassine base.
It is, therefore, an important object of the present invention to provide a method for coating glassine with a resinous lacquer composition .to form an adherent film of the lacquer on the surface of the glassine.
It is a further important object of the present invention to provide a method of pre-treating glassine so that a resinous lacquer composition subsequently applied to the glassine surface will be strongly adherent thereto.
It is a still further object of the present invention to provide a method of coating glassine with a resinous lacquer which comprises pre-treating the glassine with an aqueous solution of an alkali metal or ammonium salt of a polyvalent and slightly ionized inorganic acid.
It is a yet further object of the present invention to provide a method for the preparation of coated glassine which comprises treating the surface of the glassine with an aqueous solution of a compound selected from the group consisting of alkali metal and ammonium carbonates, silicates and phosphates, and thereafter applying a synthetic thermoplastic lacquer composition to the treated surface of the glassine.
Other and further important objects of this invention Will become apparent from the following description and appended claims.
As has been hereinbefore stated, the aqueous salt solution of the present invention comprises an aqueous solution of an alkali metal or ammonium salt of a polyvalent, slightly ionized in-.- organic acid. I have found that the alkali metal and ammonium salts of such polyprotic acids as carbonic acid, phosphoric acid, pyrophosphoric acid, metasilicic acid and orthosilicic acid are suitable salts for'use in the present invention. I have found that the sodium and potassium carbonates, phosphates and silicates and ammonium secondary phosphate are particularly desirable salts for such use.
The concentration of the salt solution is dependent upon the solubility of the salt in water at the temperature employed. I have found that may be employed in the process of the present solutions which are of sufficient concentration to deposit from 1 to 5% of the salt based on the air-dry weight of the fiber in the paper are operative to give the improved results of the pres.
ent invention. of'course, more concentrated solutions ma be employed, but since a larger amount is not necessary, it would not be commercially desirable to employ amounts in excess of about by weight.
The thermoplastic resins which may be deposited on a treated glassine in accordance with the method of the present invention are prererably resinous lacquers which foiin a trans parent, adherent film on the treated glass'ine surface. I have found various resinous lacquers,
including copolymers of vinyl chloride and vinyl acetate, chlorinated rubbers, and cycle-rubbers may be employed. These lacquers are suitable not only because of the excellent physical propcities and chemical resistance of the composi tions, but also for the heat-sealing properties of the lacquers.
as has been hereinbefore stated, the salt *solution may be applied to the web on the paper machine in intimate mixture with the plasticizer employed in the preparation of the glassine, or. alternatively, the salt solution may be applied to the paper by a size press prior to the super calendering operation. It is preferred that the aqueous salt solution be applied to the web in mixture with the plasticizers, since this method eliminates the necessity of a separate dampening bath or other apparatus for use in the applica tion of the salt solution to the paper. A
The resinous lacquer may be applied to the treated glassine by any suitable method. It is preferred that the application or the lacquer be carried out in a coating apparatus such as j a conventional double-roller coating machine, By the use of such a "double-roller coating machine, both sides of the glassine may be simultaneously coated with the resinous lacquer. Following the application of the resinuous lacquer as a solution to the treated surfaces, the wet'g1assine is heated, as by passing the "coated product through a dry tunnel, to e 'aporateth'e solvents from the lacquer and also to effect curing er the coated fiiei j warrant-11mins my intention to any'p'artiou raiproeeutie, the ronowingexampie, in writer; 1) by weight are given, will serve to illustrate nemesis its preferred form.
EXAMPLE Glassine wascoated in accordance with the present invention as follows: v "The paper was made from wood pulp pn a Fourdrinier paper making machine. A The web on the machine was passed through atank cont'aifiiii .pl'asticiz'er and an aqueous solution or a his suitable salt as hereinbefore described. The treated paperis then supeif-ealehdered by contensor-m methods used iii the manufacture of glassine. The glassine thus prepared was then passed through the rollers of a double-roller coating machine having horizontal parallel rolls placed one above the other. The bottom roll ran ina sexier lacquerfand coated the lower surface pr eg aisfsirie. fI'he upper surface of the glassine is coated by lacquer pumped from the lower lacquer pan and sprayed on the upper surface ahead of the upper roll. Any excess lacquer was removed from the coated glassine by the squeezing action of the rolis. The wet coated glassine is then passed to adrying tunnel maintained at a temperature of 150" to 200 F. to evaporate solvent from the lacquer.
The results obtained froinjth e use of a "ra es sentative groupof salts, selected from the alkali metal and ammonium phosphates, carbonates and silicates, in combination with two types of suitable resinous lacquers are tabulated in the following tables. The physical-properties of the coated l'as'sine's were determined on coated p i d ucts 'obtained by the use of a salt concentration which was suflicient tocep s t 1, 2-, and 5% r salt based on the weight of fiber ifl jth'e paper.
