Embodiment 1

[0038] Step 1: Weigh 40 parts of low-pressure polyethylene, 10 parts of linear polyethylene, 5 parts of metallocene, 5 parts of EVA, 3 parts of coloring matter, 3 parts of spices, 1 part of zinc-silver composite sepiolite antibacterial agent and add to the mixture according to parts by weight. Stir in the feeder to mix evenly;

[0039] Step 2: Add the mixed components in step 1 to a twin-screw extruder and extrude them through a film blowing machine to form a composite film. The temperature of the first temperature zone of the twin-screw extruder is 150°C, The temperature in the temperature zone is 165°C, the temperature in the third temperature zone is 175°C, and the temperature of the film head of the film blowing machine is 190°C;

[0040] Step 3: winding and collecting the composite film formed in step 2;

[0041] Step 4: The collected composite film in step 3 is cut into rolls of garbage bags by a continuous roll bag making machine.

Embodiment 2

[0043] Step 1: Weigh 40 parts of low-pressure polyethylene, 10 parts of linear polyethylene, 5 parts of metallocene, 5 parts of EVA, 3 parts of colorant, 3 parts of fragrance, 5 parts of processing waste, 1 part of calcium carbonate, carbon nano 1 part of the tube, 1 part of the zinc-silver composite sepiolite antibacterial agent is added to the mixer and stirred to mix evenly;

[0044] Step 2: Add the mixed components in step 1 to a twin-screw extruder and extrude them through a film blowing machine to form a composite film.

Abstract

The invention discloses a garbage bag and a preparation technology thereof. According to the technical scheme, the garbage bag is characterized by being prepared from components in parts by weight as follows: 50-90 parts of polyethylene, 5-10 parts of metallocene, 5-10 parts of thermoplastic resin, 3-5 parts of a pigment and 3-5 parts of perfume, wherein polyethylene comprises 40-60 parts of low-pressure polyethylene and 10-30 parts of linear polyethylene, and thermoplastic resin is EVA. Produced films are uniform in quality and excellent in tensile toughness through cooperation of the components.

Description

technical field [0001] The invention relates to the field of films, in particular to a garbage bag and a preparation process thereof. Background technique [0002] Garbage bags, as the name suggests, are bags for garbage. A small bag brings great convenience to thousands of households, and it also provides an important guarantee for environmental protection, and is even conducive to garbage recycling and classification. [0003] At present, the general garbage bags on the market are also polyethylene plastic bags used by the public: this kind of garbage bags generally use 80%-95% polyethylene as raw materials, plus 5%-20% color master powder, and blow the film through a film blowing machine These garbage bags are cheap and easy to use. At present, most of the garbage bags in the world belong to this category. [0004] However, the toughness of this type of garbage bag is low, and it is easy to break when there is too much garbage in use, causing the garbage to spill, which ...
