It is not recommended to continue cooking food in the oven after baking, because the slices of hot coils will be toxic if they are burnt.
Heat shrinkable film, also known as heat shrinkable film, is a magical film, which is similar to plastic at first. Handicrafts can be made, such as decorations. When using sandpaper, grind it evenly on the heat shrinkable sheet in the same direction until the heat shrinkable sheet looks white.
Then draw a pattern on the frosted surface with colored lead, or print it with a rubber stamp. After drawing the pattern, blow it with a hot air gun for about 1 min, during which the heat shrinkable sheet will bend and shrink, and its volume is about 1/5 of that before blowing. When the heat shrinkable sheet is completely flat, the blowing is completed, and glue can be dripped on the surface for decoration and protection.
Heating method of heat shrinkable sheet:
There are two main ways to heat the heat shrinkable board: oven and hot air gun. Usually, at the temperature of 150~200 degrees Celsius, the heat shrinkable sheet will deform and shrink within half a minute. Ordinary household hair dryer can't reach the high temperature of heat shrinkable sheet deformation, so it is not recommended.
Heat shrinkable sheets are thin sheets with smooth sides, and it is usually difficult to color other pens except marker pens. The surface of the heat shrinkable sheet after sanding has a slight matte texture, which is helpful for the adhesion of pigments and easy to color.
