Embodiment 1

[0031] A preparation method for a high-viscosity frosted precoat film, comprising the following steps:

[0032] 1) The upper surface of the BOPP film is thermally molded with a frosted pattern to form a frosted pattern layer;

[0033] 2) Carry out corona treatment to the upper and lower surfaces of the BOPP film forming the frosted pattern layer until the corona value of not less than 46 dynes is obtained to obtain the corona treated film;

[0034] 3) Extrude the hot melt adhesive particles through an extruder to form a cast film, and extrude it with the corona-treated film through a composite device, and perform ozone treatment at the same time. The ozone flow rate is controlled at 55L / h, and the direction of ozone injection is Form an angle of 40°-50° with the casting film to obtain the initial product;

[0035] 4) Carry out corona treatment to the initial product again to reach the corona value of 36-38 dynes;

[0036] 5) After eliminating static electricity, a high-visco...

[0045] 3) Extrude the hot melt adhesive particles through an extruder to form a cast film, and extrude it with the corona-treated film through a composite device, and perform ozone treatment at the same time. The ozone flow rate is controlled at 55L / h, and the direction of ozone injection is Form an angle of 40°-50° with the casting film to obtain the initial product;

[0046] 4) Carry out corona treatment to the initial product again to reach the corona value of 36-38 dynes;

[0047] 5) After eliminating static electricity, a high-visco...

Embodiment 3

[0055] A preparation method for a high-viscosity frosted precoat film, comprising the following steps:

[0056] 1) The upper surface of the BOPP film is thermally molded with a frosted pattern to form a frosted pattern layer;

[0057] 2) Corona treatment is performed on the upper and lower surfaces of the BOPP film forming the frosted pattern layer until the corona value of not less than 46 dynes is obtained to obtain a corona-treated film, and the side of the corona-treated film away from the frosted pattern layer Apply the primer, heat and dry under sealed conditions, wherein the coating speed of the primer is 2-3m / min, and the heating and drying temperature is 100-135°C;

[0058] 3) Extrude the hot-melt adhesive particles through an extruder to form a cast film, and extrude it with the film coated with the primer through a composite equipment, and perform ozone treatment at the same time. The ozone flow rate is controlled at 55L / h, and the ozone The injection direction is ...

Abstract

The invention discloses a high-viscosity frosted pre-coated film and a preparation method thereof, belonging to the field of coating films for printing. The high-viscosity frosted pre-coated film comprises a frosted pattern layer, a base material layer and a hot melt adhesive layer, wherein the frosted pattern layer is arranged on the upper surface of the base material layer, the hot melt adhesivelayer is arranged on the lower surface of the base material layer, the hot melt adhesive layer is prepared from hot melt adhesive particles, and the hot melt adhesive particles are prepared from polyester resin, a tackifier, a plasticizer, a filler and an antioxidant. According to the invention, the polyester resin is adopted and the tackifier is added, so the viscosity of the hot melt adhesive layer is improved, the adhesive property of the hot melt adhesive layer is better, and the service life of the hot melt adhesive layer is longer; the frosted pattern layer is arranged on the base material layer, so the problems of poor appearance effect of a conventional pre-coated film and poor surface friction resistance and antifouling property of a printed matter are overcome; and after the prepared high-viscosity frosted pre-coated film is compounded with a printed matter, the surface of the printed matter has uniform frosted texture and unique hand feeling, a beautifying effect is produced, and the obtained product is more attractive.

Description

technical field [0001] The invention relates to a precoating film and a preparation method thereof, in particular to a high-viscosity frosted precoating film and a preparation method thereof, and belongs to the field of printing coating films. Background technique [0002] Pre-coated film refers to pre-coating hot melt adhesive on the surface of the plastic film and then rewinding. The printing factory only needs to cover the pre-coated film on the printed matter, and adjust the laminating machine to a certain temperature and pressure, so that the pre-coated film is compatible with the printing. Paper glued together. The coated printed matter has a smoother and brighter surface due to the addition of a thin and transparent plastic film on the surface, thereby improving the gloss and fastness of the printed matter. Antifouling, abrasion resistance, folding resistance, chemical corrosion resistance, etc., are widely used in various types of paper printing such as packaging bo...
