• Sheet Forming: Then the mixture is spread on a mesh. It drains out the water particles and forms a thin sheet.  
• Pressing and Drying: The pressing is used to remove the humidity. Then it is dried in controlled heat.  
• Supercalendering: This is the critical step that gives glassine its unique texture. The dried paper is passed through a series of heated rollers under high pressure. This presses the fibers firmly. It makes the paper smooth and shiner.
• Coating: The prepared sheets are cut, rolled, and prepared for various applications. This is optional not necessary.
