specific Embodiment approach

[0014] Such as figure 1 Shown, as the best embodiment of the method for the surface treatment of a kind of adhesive tape film of the present invention, its this surface treatment method comprises the following steps:

[0015] a. Wetting the paint stage, immersing at least a part of a film coated with a paint surface in a liquid, and floating the film on the liquid;

[0016] b. In the cold transfer stage, the object is immersed in the liquid, so that the paint is transferred to the concave-convex lines on the surface of the object;

[0017] c. In the thermal transfer stage, the thermal transfer layer coating is applied to the determined film by a coating machine.

[0018] The thermal transfer layer coating in the thermal transfer stage described in stage C above includes 65% wax, 25% resin, 4% auxiliary agent and 6% colorant.

Abstract

The invention belongs to the field of sealing case, and more specifically relates to a surface treatment method of adhesive tape film. The surface treatment method comprises: a paint immersing stage; a cold transfer printing stage; a thermal transfer stage. The invention has the advantages of simple processing, and good vision, qualitative sense and touch of the surface, and ensures the product has a brand new appearance value.

Description

technical field [0001] The invention belongs to the field of box sealing equipment, and in particular relates to a method for surface treatment of an adhesive tape film. Background technique [0002] At present, packaging tape is a general-purpose packaging material, which is widely used in the packaging process of semiconductors. It can not only seal the integrated circuit to isolate the external environment, but also usually has an antistatic function, which can prevent static electricity from affecting the integrated circuit. circuit damage. [0003] With the deepening of the awareness of green environmental protection, the food and drug industries require contact materials to ensure the safety of food and drugs, and require various requirements such as good air tightness, good water resistance, and recyclability. With the continuous improvement of the quality of aseptic packaging, the barrier properties of the currently used tapes are poor and cannot meet the requiremen...
