Embodiment 1

[0020] Such as figure 2 As shown, the BOPP matting film of the present invention has a double-layer structure, consisting of a matting layer 1 and a transparent layer 2, and the components of the transparent layer 2 contain 1.5%wt antistatic agent by weight percentage, and the rest are biaxially stretched grade polypropylene resin; The composition of matting layer 1 is 100%wt matting material. Among them, the transparent layer is corona treated.

[0021] Using biaxially stretched polypropylene resin and matting material to form a two-layer structure film after co-extrusion and biaxial stretching; the matting material melt extruded from two auxiliary extruders is extruded to the same matting layer through a die adapter . It is processed into a transparent layer with a thickness of 10-18 μm and a matte layer with a thickness of 2-4 μm.

Embodiment 2

[0023] Such as figure 2 As shown, the BOPP matting film of the present invention has a double-layer structure, consisting of a matting layer 1 and a transparent layer 2, and the components of the transparent layer 2 contain 2.5%wt antistatic agent by weight percentage, and the rest are biaxially stretched grade polypropylene resin; The composition of matting layer 1 is 99%wt matting material and 1% smoothing agent, and both sides of the film are corona treated.

[0024] Using biaxially stretched polypropylene resin and matting material to form a two-layer structure film after co-extrusion and biaxial stretching; the matting material melt extruded from two auxiliary extruders is extruded to the same matting layer through a die adapter . It is processed into a transparent layer with a thickness of 10-18 μm and a matte layer with a thickness of 2-4 μm.

Embodiment 3

[0026] Such as figure 2 As shown, the BOPP matting film of the present invention has a double-layer structure, consisting of a matting layer 1 and a transparent layer 2, and the components of the transparent layer 2 contain 2%wt antistatic agent by weight percentage, and the rest are biaxially stretched grade polypropylene resin; The composition of matting layer 1 is 100%wt matting material.

[0027] Using biaxially stretched polypropylene resin and matting material to form a two-layer structure film after co-extrusion and biaxial stretching; the matting material melt extruded from two auxiliary extruders is extruded to the same matting layer through a die adapter . It is processed into a transparent layer with a thickness of 10-18 μm and a matte layer with a thickness of 2-4 μm. Both sides of the film are corona treated.

[0028] In the above three examples, since the matting layer of the BOPP matting film is relatively rough, when the matting surface touches the non-matt...

Abstract

The invention discloses a BOPP extinction film without anti-adhesion agent, wherein the extinction film is of double-layer construction, namely a transparent layer and an extinction layer, formed by co-extrusion and bidirectional tension of bidirectional tension level acrylic resin and extinction agent; the extinction agent melt mass extruded from two auxiliary extruders is extruded into a same extinction layer by a die head adapter. The transparent layer comprises 1.5-2.5% of antistatic agent; the main component of the extinction layer is extinction agent. The dispersion of the extinction agent is uniform and the extinction effect is good. No addition of anti-adhesion agent reduces the production cost. The two auxiliary extruders extrude the extinction agent into one layer to increase the extinction agent extrusion amount, therefore the production line speed and the yield is increased.

Description

technical field [0001] The invention relates to a matting film and a manufacturing method thereof, in particular to a polypropylene matting film without an anti-blocking agent (BOPP matting film for short) and a manufacturing method thereof. Background technique [0002] BOPP matting film is a fashionable and high-grade composite and packaging material. It can give people a soft, comfortable and hazy effect on vision. After being stimulated by sunlight and screens for a long time, looking at books, pictures, color-printed paintings and packaging compounded with matting film can eliminate eye fatigue. Corona matting film is suitable for printing, lamination, low temperature bronzing, etc. After gluing on the glossy surface, it can be laminated with paper or other substrates. It is often used for surface lamination of books, advertising brochures, and gift bags to make the appearance three-dimensional and feel good. [0003] The principle of matting film is that matting mate...
