CHAPTER 10: PLATEN ASSEMBLY
The platen assembly makes the vertical seam seal (also known as a
back seal) that seals the edges of the packaging material together to
produce a continuous tube. The platen assembly consists of a heater
body, cartridge heater, temperature probe, air cylinder, and a centering
hand wheel. The platen assembly components are contained in the
platen housing which swings out-of-the-way for easy access to the
forming tube assembly.
The actual platen is a rectangular aluminum bar used as a heated die
that seals the two edges of film on the back of the package to one
another. Two variations of platens are used depending on the type of
film. The resistance platen has a flat 1/2" sealing surface which is used
to activate film sealant and create a seam seal. The poly or Quali-Seal
platen has a 1/8" radius surface that creates a seam seal by melting or
welding unsupported polyethylene film structures.
