boric acid at room temperature various forms of impermeable envelopes for containing wet packaged materials such as towelettes wiping and polishing cloths and the like are well known in the art any of these may be employed in packaging the wetted towelettes of the present invention the envelopes for individual packaging may be formed of any material impervious to the liquid contents and not adversely affected thereby thus the envelopes may be made of plastic materials or of cellulosic materials lined or coated with plastic or other waterproof compositions preferably the envelope should be of a type that can be conveniently opened by tearing to remove the packaged wet towelette the following examples are illustrative of various features of articles of this invention and their method of preparation unless otherwise indicated in these examples percent refers to weight percent a 60 vinyl acetate 40 ethylene copolymer emulsion containing 4 pvoh 75 vinol 205 and 25 vinol 523 by weight of the copolymer and containing a total of 52 solids was cast to form a film of 15 mil wet thickness and air dried while the film retained its definition when immersed in water it exhibited practically no wet tensile strength as evidenced by the fact that it.
