The principle<\/strong><\/span><\/h5>\n
Extrusion is a continuous mechanical process, which consists of transforming the raw material (in the form of polyethylene granules) into a bubble which, after cooling, becomes a sheath. Once cooled and transformed, this sheath will be used as a basis for the manufacture of film, covers, bags, etc.<\/h6>\n\n\t\t<\/div>\n\t<\/div>\n\r\n\t

Detailed process<\/strong><\/span><\/h5>\n
    \n
  • The pellet mixture is fed into the screw of the extruder<\/li>\n
  • The heated screw transforms the material into a melt<\/li>\n
  • The \"melt\"<\/em> is injected into the extrusion head and then through a die<\/li>\n
  • At the exit of the die, a blowing system makes it inflate, and gives it the shape of a tubular sheath<\/li>\n
  • The resulting sheath is then cooled and laid flat before being reeled.<\/li>\n<\/ul>\n\n\t\t<\/div>\n\t<\/div>\n\r\n\t
