Definitions

  • a high degree of resistance to the transmission of moisture vapor through the walls of a tubular or other form of plastic container is attained by the in-line coating of the outer surface of such containers with polyvinylidene chloride applied in the form of an aqueous emulsion.
  • Coating with the emulsion is attained by (a) passing the plastic container through and in wiping contact with a resilient porous medium, such as a sponge saturated with the emulsion, thereby leaving a coating of the emulsion on the container; and (b) evaporating ofl. the water content of the deposited emulsion by heating the emulsion coated container in a current of air to leave a. very thin, highly moisture-resistant polyvinylidene chloride coating adhered to the outer surface of the container.

Abstract

A HIGH DEGREE OF RESISTANCE TO THE TRANSMISSION OF MOISTURE VAPOR THROUGH THE WALLS OF A TUBULAR OR OTHER FORM OF PLASTIC CONTAINER IS ATTAINED BY THE IN-LINE COATING OF THE OUTER SURFACE OF SUCH CONTAINERS WITH POLYVINYLIDENE CHLORIDE APPLIED IN THE FORM OF AN AQUEOUS EMULSION. COATING WITH THE EMULSION IS ATAINED BY (A) PASSING THE PLASTIC CONTAINER THROUGH AND IN WIPING CONTACT WITH A RESILIENT POROUS MEDIUM, SUCH AS A SPONGE SATURATED WITH THE EMULSION, THEREBY LEAVING A COATING OF THE EMULSION ON THE CONTAINER; AND (B) EVAPORATING OFF THE WATER CONTENT OF THE DEPOSITED EMULSION BY HEATING THE EMULSIONCOATED CONTAINER IN A CURRENT OF AIR TO LEAVE A VERY THIS, HIGHLY MOISTURE-RESISTANT POLYVINYLIDENCE CHLORIDE COATING ADHERED TO THE OUTER SURFACE OF THE CONTAINER.
