So-called Heat Transfer Film printing is to use a heated roller to transfer the ink onto the product which can befor plastic, glass or metal.
Feature of Heat Transfer Film
Gravure printing presents delicate full color by applying pearl, metallic ink and metallization not only enhanced the product value but also kept competitive cost while mass production.
The practical application of Heat Transfer Film
Heat Transfer Film printing technology can be printed on a variety of materials (most common for plastic), so it has a wide range of applications, including Housewares, stationeries, cosmetics, appliances and janitorial, all can use this printing technology to make the utensils more beautiful and shiny. SENTIEN is a professional supplier of Heat Transfer Film materials, providing you with the highest quality film in the world.

The raw material of Heat Transfer film is PET film ( the thickness is 19um/23um/36um/50um)
The heat transfer film of Sentien printing factory almost applicated in plastic products, such as cosmetic containers, toys, electrical appliances, building material, stationery, houseware..etc (general plastics are available)
The heat transfer machine will adjust different temperature and pressure according to difference products, then transfer the ink of heat transfer film on the plastic products.
According to the appearance of products to adjust the transfer of temperature, pressure, speed.
The main transfer require the interactive adjustment of these tree paraments and the quality of the fixture is also an important key to the success of transfer.
The transfer temperature need higher than injected raw plastic.
For explain PP material is 180 degrees Celsius, ABS is 200 degrees Celsius up) and the speed of transfer is also another important interactive adjustment.
According to the size of transfer plastic and design.
2. the product will use transfer film for check the template (diecut size)
The heat transfer machine mainly uses a heated rubber wheel (plate) (usually cylindrical or flat) to form a high temperature condition on the transfer object.
And the direction of pressure of the rubber wheel (plate) needs to be in line contact with the transfer object or plane contact.
If it cannot be adhered to the transfer object, the effective transfer effect cannot be achieved, so the non-planar shape cannot be transferred.
For metal need to warm up before transfer and also need to keep the high temperature after transfer for some time.For glass, after transfer, need to keep the high temperature around 30 minutes in order to let the transfer can complete.
