Embodiment 1

[0013] 1. Determine the thickness of the matting layer according to the individual requirements of the specific tobacco factory, so that the haze meets the requirements of the manufacturer;

[0014] 2. Select matting material containing polypropylene, polyethylene and white pigment as the surface layer, select polypropylene material containing vinyl segment as the other surface layer, and polypropylene resin as the middle layer, and send them into the corresponding extrusion In the extruder, the temperature of the extruder is controlled at 245°C, 255°C, and 230°C respectively, so that the above materials are melted and extruded from the same die to cast one surface layer as a matte layer, the other surface layer as a bright layer, and the middle layer as a A thin layer of the base layer;

[0015] 3. Stretch the film longitudinally at a temperature of 100°C on the matting surface and at a temperature of 87°C on the other side, with a stretching ratio of 4.8 times, and transvers...

Embodiment 2

[0017] 1. The thickness and haze of the established matting layer;

[0018] 2. Select matting materials containing polypropylene, polyethylene and white pigments as the middle layer, select polypropylene materials containing vinyl, butenyl, and hexenyl segments as the two surface layers, and select C 5 and or C 9 The polypropylene resin of the petroleum resin is the other two intermediate layers, which are respectively fed into the corresponding extruders, and the temperature of the extruders is controlled at 230°C, 252°C, 233°C, 250°C, and 230°C to melt the above materials and remove them from the Extrude from the same die to cast a sheet layer in which one of the middle layers is a matte layer, the two surface layers are polypropylene layers, and the other two middle layers are base layers;

[0019] 3. Stretch the film longitudinally at a temperature of 82°C with a stretching ratio of 5.65 times, and stretch it transversely at a temperature of 145°C at a stretching ratio of...

Embodiment 3

[0021] 1. The thickness and haze of the established matting layer;

[0022] 2. Select the matting material containing polypropylene, polyethylene and white pigment as the surface layer, select the polypropylene material containing vinyl segment as the other surface layer, and select the material containing C 5 and or C 9 The polypropylene resin of the petroleum resin is used as the four-layer intermediate layer, and is sent into the corresponding extruder respectively, and the temperature of the extruder is controlled at 242°C, 255°C, 255°C, 255°C, 255°C, and 225°C to make the above materials Melted and extruded from the same die, cast into a sheet layer in which one surface layer is a matte layer, the other surface layer is a bright layer, and the middle layer is a four-layer base layer;

[0023] 3. Stretch the film longitudinally at a temperature of 100°C on the matting surface and at a temperature of 80.5°C on the other side at a stretching ratio of 5.70 times, and stretch...

Abstract

The invention discloses a delustring smoke film, which is characterized by the following: the longitudinal tensile strength is 120-200N / mm2; the transversal tensile strength is 220-350N / mm2; the inner / inner friction coefficient is 0.15-0.6; the outer / outer friction is 0.2-0.5; the longitudinal elongation at break is 150-180%; the transversal tensile strength is 50-70%; the longitudinal heat shrinkage is 3-10%; the transversal is 3-10%; the glossiness of the delustring smoke film is 6-40%; the mist degree is 30-85%; the heat seal temperature is 100-125deg C; the heat seal strength is 2.0-3.5N / 15mm; the smoke film forms typical and elegant delustring effect, which makes the cigarette packet forms twilight and soft packing peculiarity, meanwhile it can't make any effects on the cigarette packet pattern, words and colors.

Description

technical field [0001] The invention relates to a cigarette packaging film, in particular to a cigarette packaging film with matting effect. Background technique [0002] At present, the films used on cigarette packages are mainly transparent films, and in order to highlight the packaging features and visual effects of various brands of cigarettes, various cigarette manufacturers have designed dazzling patterns and logos on cigarette packages, expecting consumers to Recognizable at a glance. As the most attractive colors are reused, the appearance of the same product is becoming more and more prominent. But as far as the existing packaging film is concerned, it is still not enough to overcome the various deficiencies in the prior art, and it is difficult to show a novel appearance and adapt to market demand. Therefore, it is necessary to improve the prior art. Contents of the invention [0003] The purpose of the present invention is to provide a matte cigarette film, s...
