Embodiment 1

[0024] This embodiment provides an easy-to-tear plastic film material, comprising the following components by weight percentage:

[0025]

[0026] The filler is aragonite formed from natural minerals.

[0027] The preparation process of the above-mentioned easy-to-tear plastic film material is as follows:

[0028] (1) Mixing: Weigh 600kg of polyethylene, 190kg of polypropylene, 190kg of aragonite formed from natural minerals and 20kg of polystyrene to form a uniform mixture;

[0029] (2) Mixing: Use a twin-screw extruder to mix the mixture. During mixing, the temperature of the main engine is 230°C, the pressure of the barrel and the screw is 3MPa, and extrude to obtain a strip-shaped compound;

[0030] (3) Cooling: further cooling the strip-shaped kneaded material through the cooling water tank;

[0031] (4) Moisture removal: use a blower to remove the surface moisture of the cooled strip kneading material;

[0032] (5) Pelletizing: Pelletize the strip-shaped kneaded ma...

Embodiment 2

[0035] This embodiment provides an easy-to-tear plastic film material, comprising the following components by weight percentage:

[0036]

[0037] The filler is lignin.

[0038] The preparation process of the above-mentioned easy-to-tear plastic film material is as follows:

[0039] (1) Mixing: Weigh 190kg polyethylene, 600kg polypropylene, 200kg lignin and 10kg polystyrene to form a uniform mixture;

Abstract

The invention provides an easy-to-tear plastic film material. The easy-to-tear plastic film material comprises the following components: by weight, 19% to 60% of polyethylene, 19% to 60% of polypropylene, 19% to 59% of fillers, and 1% to 6% of polystyrene. In addition, the invention also provides preparation technology of the easy-to-tear plastic film material. According to the present invention, through addition of the fillers in the polyethylene, the polypropylene and the polystyrene, and further through a specific ratio design, plastic films prepared through use of the formulation not only retain originally traditional good performances, but also have the properties of being easy to tear and fold, and easy for retaining impression. The plastic films can be used in a very wide range.

Description

technical field [0001] The invention relates to a plastic film material, in particular to an easily tearable plastic film material and a preparation process thereof. Background technique [0002] At present, there are many kinds of plastic films, and the materials of these plastic films are mostly polyethylene (PE). In general, plastic films are superior to paper in demanding applications, for example, they are a vapor or liquid barrier, have good strength, electrostatic adsorption, and lint-free properties, and can bend smoothly; to a certain extent, plastic films Possibly cheaper than paper, too. [0003] However, due to the limitations of the materials used, the traditional plastic film has the following defects: the plastic film is difficult to be torn or torn in the expected direction; the plastic film that has been indented or folded during the production process is not conducive to its production Retention of indentations and creases after completion.
