Heat transfer film for plastic is a type of transfer paper that is used to apply designs, graphics, logos, and other images or text onto plastic materials, such as polyethylene, polypropylene, polystyrene, and PVC. The transfer film is printed with the desired design using a special ink that can be transferred to the plastic surface through the application of heat and pressure. The film is typically applied using a heat press, which applies heat and pressure to the film, causing the ink to bond with the plastic surface. Heat transfer film for plastic is commonly used for a wide range of applications, including product labels, signage, and promotional items.
