Problems solved by technology

In the prior art, this kind of paper cup has the following problems: first, the printing is directly printed on the base paper, the outermost layer is not coated, and the product packaging method is to use a sleeve cup. There will inevitably be friction during the process, and the printed color will fall off on the inner wall and adhere to the polyethylene coating layer; second, when consumers use it, opening the sealing film will produce a lot of paper fiber burrs
This is because the thickness of the polyethylene coating on the inner layer of the cup is relatively thin, and it is easily damaged when it is torn apart, thereby exposing the paper fibers. When used, the paper fibers may enter the human body, posing a certain safety hazard.

Embodiment 1

[0024] A new type of paper cup, which is made of BOPP plastic film on the outer layer, white cardboard and PE coating film on the inner layer.

[0025] The PE coating is composed of the following raw materials in parts by weight: 80 parts of polyethylene, 5 parts of calcium carbonate, 2 parts of mussel powder, 0.5 part of calcium gluconate, and 0.1 part of polylysine.

[0026] The mussel powder is prepared by the following method: adding fresh mussels to 3% polyethylene glycol by weight of mussels, beating, then adding succinic acid accounting for 0.3% by weight of mussels, 1.5% nutmeg powder, stir well and let it stand for 20 minutes, then freeze-dry, crush and pass through a 100-mesh sieve;

[0027] The preparation method is as follows:

[0028] (1) Mix the PE coating with a high-speed mixer according to the formula, and then soften it to form a coating material;

[0029] (2) Spray the coating material on the white cardboard to form a coating paper with a coating thickness...

Embodiment 2

[0032] A new type of paper cup, which is made of BOPP plastic film on the outer layer, white cardboard and PE coating film on the inner layer.

[0033] The PE coating is composed of the following raw materials in parts by weight: 85 parts of polyethylene, 3.5 parts of calcium carbonate, 3 parts of mussel powder, 0.65 parts of calcium gluconate, and 0.1 part of polylysine.

[0034] The mussel powder is prepared by the following method: adding fresh mussels to 2% polyethylene glycol by weight of mussels, beating, then adding succinic acid accounting for 0.5% by weight of mussels, 2% by weight of mussels, 1.2% nutmeg powder, stir evenly and let it stand for 20 minutes, then freeze-dry, crush and pass through a 100-mesh sieve;

[0035] The preparation method is the same as in Example 1.

Embodiment 3

[0037] A new type of paper cup, which is made of BOPP plastic film on the outer layer, white cardboard and PE coating film on the inner layer.

[0038] The PE coating is composed of the following raw materials in parts by weight: 90 parts of polyethylene, 5 parts of calcium carbonate, 3 parts of mussel powder, 0.8 part of calcium gluconate, and 0.1 part of polylysine.

[0039] The mussel powder is prepared by the following method: adding fresh mussels to 3% polyethylene glycol by weight of mussels, beating, then adding succinic acid accounting for 0.4% by weight of mussels, 1% nutmeg powder, stir well and let it stand for 20 minutes, then freeze-dry, crush and pass through a 100-mesh sieve;

[0040] The preparation method is the same as in Example 1.

Abstract

The invention belongs to the technical field of living goods and particularly relates to a novel paper cup and a preparation process thereof. The paper cup is prepared from an outer layer of BOPP plastic film, a white paperboard and an inner layer of PE spraying film. The inner layer can be prevented from being contaminated by printing coating through a multi-layer composite process, so that safety and sanitation are realized; moreover, the cup body does not have paper odor and the stiffness retainability is high; the spraying film provided by the invention has high strength and high viscosity, avoids the phenomenon that paper fiber burr is exposed during use, has high moisture resistance, high strength and high sealing property, is environmentally-friendly and sanitary, has small use amount and can be reused; and the paper cup provided by the invention is safe and sanitary and can prolong the storage life of food such as yogurt.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a novel paper cup and a preparation process thereof. Background technique [0002] Coated paper cups are a very common product now. It is a paper-plastic composite structure with a layer of paper on the outside and a layer of polyethylene plastic film on the inside, which is the side that contacts the food. The production process of coated paper cups is to use a coating machine to coat polyethylene on the base paper, and then print the cardboard through a printing machine. The cup body is cut out of sheet material on a die-cutting machine, and the cup bottom is made of roll material, which is punched by the punching system of the cup making machine. The material of the cup bottom is also polyethylene, and the joint of the cup body and the joint of the cup body and the cup bottom Through the hot pressing process, the polyethylene coating is hot-melted to com...
