Problems solved by technology

[0003] In the existing production process of coated paper, it takes a certain amount of time to mix and stir different formulations, and this process requires a lot of power consumption. In some cases, even if it takes a certain amount of time, it cannot Ensure that the raw materials are evenly dispersed, which will lead to poor bonding ability between the film layer and the substrate layer of the final coated paper, which cannot meet the use requirements

Embodiment 1

[0044] see Figure 1-7 A production process of coated paper applied to food packaging, which comprises the following steps:

[0045] S1. Add the raw materials polyvinyl alcohol, sodium carboxymethyl cellulose, defoaming agent, antibacterial liquid, and deionized water into the reaction vessel 1 in batches according to different proportions, at 28-30 ° C, and the rotating speed is 400-800 r / min. Stir and disperse evenly, heat to 75-80°C and continue to dissolve for 15-30min, then dilute to a concentration of 6-8% to obtain a coating material;

[0046] S2. Mount the base paper on the corona roller of the corona machine for corona surface treatment to roughen the surface of the base paper; it can increase the surface tension of the base paper, and then make the coating material better bond to the treated base paper surface;

[0047] S3. Load the laminating material into the hopper of the laminating machine, put the corona-treated base paper into the laminating machine, and spray...

Embodiment 2

[0060] The side end surface of the material box 2 is fixedly connected with a hanging lug 2-1. The material box 2 is suspended at the upper edge of the reaction container 1 through the hanging lug 2-1 to realize a detachable connection with the reaction container 1. The material box 2 is connected to the inner wall of the reaction container 1. Fittingly, through the use of the hanging lugs 2-1, on the one hand, it is convenient to place the material box 2 at any position on the reaction vessel 1, and it is not necessary to find a specific position for installation, and it is easy to remove, on the other hand, it is convenient to use according to the needs of use. (When the reaction container 1 is applied to other material mixing environments) a plurality of material boxes 2 are arranged, and the easy disassembly operation mode between the material box 2 and the reaction container 1 facilitates the removal of the adjustment structure 4 for cleaning operations.

Embodiment 3

[0062] The bottom end of the material box 2 is set as an inclined structure, and the inclination direction is inclined downward relative to the inner wall of the reaction container 1. The difference between Example 3 and Example 2 is that the shape of the bottom end of the material box 2 is different, and the inclined setting of the material box 2 can not only The unloading of raw materials is convenient, and the surface of the hanging lugs 2-1 located in the material box 2 is less likely to have residual raw materials, and at the same time, the cleaning operation of the material box 2 is convenient.

Abstract

The invention discloses a coated paper applied to food packaging and a production process of the paper, and belongs to the field of coated paper. A coated paper applied to food packaging and a production process of the paper, the raw materials polyvinyl alcohol, sodium carboxymethyl cellulose, defoaming agent, antibacterial liquid, and deionized water are added to a reaction vessel in batches according to different proportions , stir and disperse evenly at 28-30°C and rotating speed of 400-800r / min, heat to 75-80°C and continue to dissolve for 15-30min, then dilute to a concentration of 6-8% to obtain a coating material; Corona surface treatment is carried out on the corona roller of the machine to roughen the surface of the base paper; the laminating material is put into the hopper of the laminating machine, the corona-treated base paper is loaded into the laminating machine, and the mixture It can be sprayed on one or both sides of the base paper and dried to obtain the finished coated paper. By adding the raw materials to the reaction vessel in batches for mixing, the mixing rate of the raw materials can be accelerated, thereby improving the bonding between the coating material and the base paper. ability.

Description

technical field [0001] The invention relates to the field of coated paper, more particularly, to a coated paper applied to food packaging and a production process of the paper. Background technique [0002] In addition to protecting food, preventing damage from external factors and maintaining the stable quality of food itself, food packaging materials can effectively attract consumers if they have a good printing effect after printing, and have a value other than material cost. . In the field of food packaging materials, some liquid foods require packaging materials with waterproof, oil-proof, heat-sealing and thermal insulation functions, such as instant noodles, cold drinks and hot drinks. Coated paper is widely used in the current market for this type of food packaging needs. The so-called coated paper is a composite material that processes plastic particles such as polyethylene (PE) and polypropylene (PP) on the surface of the paper by casting and other processes. ; T...
