Knowledge about the film and heat transfer film in Haining!

The common Q1: plate?

One, common board: surface does not handle, the color is single. (some kind of product, the cost is low, is not beautiful, no market)

Mask plate: in the plate is stuck to the surface of a layer of PVC decorative layer, but PVC paste skin color has its limitations, only to wood texture Kyo, environment, temperature, humidity changes are prone to spalling blister on the surface of the pinch plate.

Printing plate surface after printing ink fixation, polishing processing, this kind of gusset plate common) but due to color printing to create lifelike, exquisite pattern effect, so not too popular.

Four, transfer printing plate: the world's most advanced plastic surface treatment process, design by the computer development and control, can be manufactured in any pattern of color, forming the transfer film, through the transfer film transfer printing to plastic sheet surface.

What is the physical structure and chemical structure of the Q2: thermal transfer film?

Thermal transfer film flower refers to adhesive with graphic, under the joint action of heat and pressure, together with the isolation layer together from a carrier film, firmly transfer in the substrate surface of the special function of printing film.

Thermal transfer film is generally made up of 3 to 5 layers. Three layers of thermal transfer film is composed of a basal layer, a printing layer and adhesive layer, four layers of thermal transfer film by basal layer, from type layer, a printing layer and adhesive layer structure; five layers of heat transfer film by basal layer, from the type layer, a printing layer, adhesive layer and the hot melt adhesive powder layer.

Four layers of thermal transfer film structure, the following four layer transfer film as an example to explain the requirements of each layer and its role.

The basal layer: from the carrier agent, printing ink and adhesive coating, the carrier temperature, pressure, tensile deformation. Off layer: it is a coating that is a layer of coating. It can be melted at a certain temperature, and can be melted at a certain temperature, and the adhesion between the substrate and the substrate is small, and can be quickly detached from the substrate, and no adhesion remains. The off - type agent is the key to complete the printing layer from the substrate layer and transfer to the surface of the substrate. It requires a good wear resistance, to protect the color ink, reduce the radiation intensity of ultraviolet radiation, reduce the air in the negative factors of ink, the role of the ink, and can buffer film and printing layer adhesion. Print layer: this layer is the basic of the beauty of the texture of the product. Along with the progress of printing technology, the development of image processing technology, printing layer has a variety of colors, various patterns. Especially by gravure printing graphics, can well reflect the delicate picture, make it more perfect packaging decoration effect. Adhesive layer: its basic performance is with the surface of the substrate has high bond strength, ensure the printing layer and the substrate surface is firmly combined. The adhesive layer must match the printing material. Different adhesives, due to the different chemical composition, bonding with the substrate far. Should be based on different substrates, to choose.
