Problems solved by technology

[0006] However, the paper-plastic packaging cannot be completely bonded to the product. During the storage and transportation process after the product is packaged, the product will rub against the inner surface of the paper-plastic packaging due to vibration and other reasons, resulting in fine flakes on the inner surface of the paper-plastic packaging.
These fine hairs are easy to adhere to the surface of the product, or enter the interior of the product through the holes and gaps on the surface of the product, which will have a negative impact on the performance of the product

Embodiment 1

[0045] A paper-plastic packaging anti-pilling sealing coating process, with reference to figure 1 and figure 2 , which includes the following steps:

[0046] Prepare α-chitin into an aqueous solution with a concentration of 10wt% with hot water at 90°C, filter while it is hot, and obtain a sealing solution for future use. The sealing liquid is sprayed through the high-pressure nozzle 21 into the atomization chamber 2 equipped with a heating device, and a uniform and fine mist of the sealing liquid is formed in the atomization chamber 2 . The inside of the atomization chamber 2 is heated to 90° C. with a heating device in advance and kept warm. Then, the formed paper-plastic package 1 is sent into the atomization chamber 2 with the opening facing up by means of the conveyor 4, and the residence time of the paper-plastic package 1 in the atomization chamber 2 is controlled to be 3 seconds, so that the surface of the paper-plastic package 1 is evenly adhered to Layer sealing ...

Embodiment 2

[0048] A paper-plastic packaging anti-pilling sealing coating process, with reference to figure 1 and figure 2 , which includes the following steps:

[0049] Use an aqueous solution of acetic acid at 80°C and a concentration of 5wt% to prepare the sealing agent into an aqueous solution with a concentration of 12wt%. : 1 ratio, filtered while hot, to obtain the sealing solution for later use. The sealing liquid is sprayed through the high-pressure nozzle 21 into the atomization chamber 2 equipped with a heating device, and a uniform and fine mist of the sealing liquid is formed in the atomization chamber 2 . The inside of the atomization chamber 2 is heated to 95° C. with a heating device in advance and kept warm. Then, the formed paper-plastic package 1 is sent into the atomization chamber 2 with the opening facing upwards by means of the conveyor 4, and the residence time of the paper-plastic package 1 in the atomization chamber 2 is controlled to be 20s, so that the surf...

Embodiment 3

[0051] A paper-plastic packaging anti-pilling sealing coating process, with reference to figure 1 and figure 2 , which includes the following steps:

[0052] Prepare N-maleyl chitosan into an aqueous solution with a concentration of 10 wt% by using an aqueous solution of acetic acid at 80°C and a concentration of 5 wt%, and filter while it is hot to obtain a sealing solution for use. The sealing liquid is sprayed through the high-pressure nozzle 21 into the atomization chamber 2 equipped with a heating device, and a uniform and fine mist of the sealing liquid is formed in the atomization chamber 2 . The inside of the atomization chamber 2 is heated to 90° C. with a heating device in advance and kept warm. Then, the molded paper-plastic package 1 is sent into the atomization chamber 2 with the opening facing up by means of the conveyor 4, and the residence time of the paper-plastic package 1 in the atomization chamber 2 is controlled to be 10s, so that the surface of the pap...

Abstract

The invention discloses a paper plastic package anti-fluffing sealing and coating process, and relates to the technical field of paper-plastic package processing. According to the technical scheme, the paper plastic package anti-fluffing sealing and coating process comprises the following steps of preparing sealing and coating liquid, wherein a sealing and coating agent is prepared into an aqueoussolution to obtain the sealing and coating liquid, and the sealing and coating agent is selected from one or more of chitin, derivatives of the chitin, water-soluble cellulose ether, derivatives of the water-soluble cellulose ether, water-soluble bioglue or water-soluble synthetic high molecular polymer; conducting spraying, wherein a spraying manner is adopted for evenly applying the sealing andcoating liquid to the paper-plastic package surface; and conducting heat treatment, wherein a paper-plastic package treated by spraying is heated at 200 DEG C to 230 DEG C for 5 s to 90 s. A paper-plastic product treated by the process has a smooth surface, and fine debris is not prone to being generated in the storage and transportation processes. Another object of the invention is to provide the paper-plastic package. After sealing and coating treatment with the paper plastic package anti-fluffing sealing and coating process, the advantage that the fine debris is not prone to being caused by friction is achieved.

Description

technical field [0001] The invention relates to the technical field of paper-plastic processing, more specifically, it relates to a paper-plastic packaging anti-fluff sealing coating process and paper-plastic packaging. Background technique [0002] There are generally three packaging methods for common mobile phones and computer electronic products: [0003] One is to use packaging boxes made of foam materials for packaging. Although foam materials are easy to process and widely used, they are the main environmental pollutants. Because they cannot be recycled and reused, they are basically not degradable in the natural environment and will burn when burned. Release toxic gas, so its large-scale use is not conducive to environmental protection; the second is to use paper for packaging, although it is very convenient to use paper for packaging, but the production of paper requires a lot of raw materials (specifically plant fibers), and the cost Expensive; the 3rd, the foam i...
