How to Bend a Plastic Sheet


Plastic becomes pliable with the application of heat. With the assistance of a strip heater and clamps, you can bend a sheet of plastic for use in craft and construction projects. You can find all the items you need at most hardware stores to complete a simple, straight-line bend on a plastic sheet.

Things You'll Need

  • Permanent marker
  • 2 flame-retardant saw horses
  • 2 clamps
  • Strip heater
  • Heavy cotton safety gloves
  • Mark the location where you want to bend your plastic sheet, using a permanent marker to make a light tic at either edge of the line.

  • Position the plastic sheet so that the area you will bend is between two flat, flame-retardant surfaces, like saw horses. Secure the sheet in place by using clamps on both ends.

  • Put on cotton safety gloves.

  • Position a strip heater at the recommended safe distance from the plastic, as directed by the manufacturer.

  • Heat the plastic until it begins to sag away from the heating element. Remove the clamps, while still wearing your safety gloves.

  • Manipulate the edges of the plastic, carefully with gloved hands, until you achieve the degree of bend you desire.

  • Clamp the hot plastic into place and leave it for 24 hours to cool fully.
