摘要： Polyvinyl alcohol films are provided which are gelled, non-tacky, bubble-free and resistant to water at ambient temperatures. The polyvinyl alcohol film is obtained by plasticizing (fluxing) and melting granules of pure polyvinyl alcohol containing from 25 to 35% by weight of water at a temperature at least 100.degree. C. above the equilibrium melting point of the granules and less than or equal to 220.degree. C., and extruding the melted granules through a die at a temperature at least 5.degree. C. above the equilibrium melting point of the granules and less than or equal to 98.degree. C., optionally followed by monoaxial stretching or biaxial stretching of the unstretched film obtained. The stretched or unstretched film may be heat-treated to improve its properties. The polyvinyl alcohol film can be used to prepare with thermoplastic films composite films or sheets having a high gas impermeability. The invention also provides composite, biaxially oriented, impermeable barrier layer coated, thermoplastic hollow shaped articles useful as packaging material, e.g., as packages and bottles for flavored foods and carbonated beverages. The hollow shaped articles are produced by externally barrier covering a thermoplastic tubular blank, parison or preform with a relativley thick barrier layer consisting essentially of water-resistant and highly crystalline polyvinyl alcohol, said barrier layer having been prepared by shaping a melt of homogeneously shear fluxed and molten flakes of pure polyvinyl alcohol having a water content of 25 to 35% by weight thereof, with said shear fluxing and melting of said polyvinyl alcohol flakes being at a temperature above the equilibrium melting point of the polyvinyl alcohol/water admixture essentially constituting said flakes, and said shaping being at a temperature of at least said equilibrium melting point but less then that at which the vapor pressure of the component water would effect the surface expansion and bubbling of the desired barrier layer, and then biaxially orienting and blow molding into final configuration said barrier covered blank, parison or preform.

摘要： A process for preparing biaxially oriented hollow shaped articles, in particular bottles of thermoplastic material, by biaxial draw- and blow-molding comprises blow-molding a preform and subsequently maintaining the thermoplastic material in close contact with the hot walls of the mold at a temperature which is in the range from about the minimum effective temperature for biaxial orientation of the thermoplastic material to about 40.degree. C. above this temperature for a period of time which is sufficient to partially reduce internal residual stresses in the hollow shaped articles. Following this partial thermo-stabilization, the hollow shaped article preferably is subjected to cooling, whereby the pressure within the article is at least partially maintained or the shaped article is cooled or allowed to shrink and subsequently subjected to a second blow-molding procedure.

摘要： A method for the continuous coating of at least one metal strip with a fluid, crosslinkable polymer film free from solvent or diluent and having a thickness less than that of the metal strip. The process firs continuously moves the metal strip on at least one support roller, pre-heats the strip, forms by forced flow, on a pinch roller on a lap of the crosslinkable polymer, heats and drives in rotation the pinch roller in the same direction as the support roller, and forms the crosslinkable film by compressing, between the pinch roller and the metal strips, an applicator element with a deformable surface, heated and driven in rotation in the same direction as the support roller to transfer the film from the pinch roller onto the applicator element and from the applicator element onto a metal strip. A coating device for implementing this method is also disclosed.

摘要： The invention concerns a method for continuously coating at least a metal strip with a crosslikable polymer fluid film free of non-active solvent or diluent and whereof the softening temperature is higher than 50° C. The method consists in continuously unwinding the metal strip (1) on at least a back-up roll (3); forming, on a roll (20) by forced flow, a layer of said crosslinkable polymer in melted state; forming, from said layer (30), said crosslinkable polymer film (31); and transferring entirely in thickness said film onto the metal strip (1) and, between the zone forming the layer (30) on the roll (20) and the zone applying the film (31) on the metal strip, in thermally conditioning the crosslinkable polymer to reduce its viscosity. The invention also concerns a coating device for implementing said method.
