Embodiment Construction

[0009] Such as figure 1 As shown, the pre-coated film with anti-ultraviolet function is composed of a secondary functional layer 1, a core layer 2, and a coating functional layer 3. The core layer 2 is located between the secondary functional layer 1 and the coating functional layer 3; the secondary functional layer The material of 1 is composed of polypropylene (PP) and anti-ultraviolet agent, and the addition of anti-ultraviolet agent is 0.1-3% of the mass of polypropylene; the material of core layer 2 is modified polyethylene (PE), and the functional layer is coated The material of 3 is an adhesive; the secondary functional layer 1, the core layer 2, and the coating functional layer 3 are heat-synthesized as one (feeding into an extruding compound machine for extrusion and heat-synthesizing, and the heat-sealing temperature is 85-120° C.).

[0010] The function of the secondary functional layer 1 is the appearance of the film and anti-ultraviolet rays. By adding additives t...

Abstract

The present invention relates to a film for packaging. A pre-coated film with anti-ultraviolet function is characterized in that it consists of a secondary functional layer, a core layer, and a coating functional layer, and the core layer is located between the secondary functional layer and the coating functional layer; the material of the secondary functional layer includes poly Composed of propylene and anti-ultraviolet agent, the addition of anti-ultraviolet agent is 0.1-3% of the mass of polypropylene; the material of the core layer is modified polyethylene, and the material for coating the functional layer is an adhesive; the sub-functional layer, core layer, The coated functional layer is thermally synthesized into one body. The invention has the characteristics of anti-ultraviolet function and convenient and simple use.

Description

technical field [0001] The present invention relates to a film for packaging. Background technique [0002] Composite the film on the paper or plastic used for packaging, usually by applying glue on the paper or plastic, then heating and adhering the film. There are deficiencies such as complex process, high requirements for production equipment and high production cost. At the same time, the existing packaging film has many layers and complex structures, and does not have the function of preventing ultraviolet rays. Contents of the invention [0003] The object of the present invention is to provide a precoat film with anti-ultraviolet function, which is convenient to use and has anti-ultraviolet function. [0004] In order to achieve the above object, the technical solution of the present invention is: a precoat film with anti-ultraviolet function, characterized in that it is composed of a secondary functional layer, a core layer, and a coating functional layer, and th...
