The first shaping method is a steady continuous process. It is among the oldest methods, and is used extensively in the rubber and plastics industries. It includes the classic calendering, as well as various continuous coating operations, such as knife and roll coating. 

Smoothness Smooth base paper gives a uniform and closed coated surface. The various coating processes have slightly different smoothness requirements. Air knife coaters require a relatively smooth surface because, in that method, coating... 

PVC can be rigid or flexible, clear or opaque. It can be processed as a solution, paste, or powder extruded injection-, dip-, or rotomolded knife- or reverse-roll coated. It is easily printed and bonded by heat, radiofrequency welding, or solvent. This chapter reviews monomer synthesis, types of resin and their manufacturing methods, additives, compounding, and processing into the myriad finished products of the vinyl industry. 

Adhesion test method ISO 2409 is quite similar, except the cuts are made into the coating using a special knife and results are classified based upon the amount of coating removed from the surface after the cutting process.
