Problems solved by technology

[0003] At present, the surface of the paper tray made of general raw materials is prone to dander, discoloration, impurities, wrinkles, and cracks. For some products, dander will be adsorbed on the surface, and discoloration, impurities, wrinkles, and cracks are even more serious. Directly affect the packaging effect of the product, the surface of the paper tray is not high-grade visually and the touch is not soft, and the color of the paper tray cannot be diversified
In order to solve these problems, the conventional operation is to improve the grade of raw materials, use better high-quality materials, and use better equipment and molds. Although this can solve a small part of dander, discoloration, impurities, wrinkles, and cracks , but the cost is greatly increased and cannot fundamentally solve dander, fading, impurities, wrinkles, cracking, vision, touch, and the main raw materials need to be imported from abroad, so it is very inconvenient for production

Embodiment Construction

[0015] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0016] Such as figure 1 with figure 2 As shown, a kind of paper tray processing technology provided in this embodiment includes the following steps:

[0017] 1. Mix raw starch, water and stone powder or talcum powder or calcium carbonate at the same time and stir evenly to make a mixed liquid;

[0018] 2. Spray or coat the mixture evenly on the surface of the paper tray to form a coating;

[0019] 3. Put the sprayed paper tray into the steam box and steam for 30s-90s by steam. The curve of temperature and time during the curing process of the coating is shown as follows: figure 2 As shown, the surface of the coating is preliminarily matured at 20s, the middle layer of the coating is preliminarily cured at 30s, the bottom layer of the coating is...

Abstract

The invention discloses a paper tray processing technology. The technology comprises the following steps of: S1, mixing raw starch, water and stone powder or talcum powder or calcium carbonate put in at the same time, and stirring well to obtain a mixed solution; S2, uniformly spraying or applying the mixed solution to the surface of a paper tray to form a coating; S3, putting the sprayed or coated paper tray into a steam box, and steaming for 30-90 seconds by water vapor until the raw starch in the coating becomes half-cooked or full-cooked starch; and S4, putting and drying the steamed paper tray in an oven, and after drying is completed, taking the paper tray out. The coating is arranged on the surface of the paper tray, so that soft flocks, fading, impurities, wrinkles and cracks do not exist on the surface of the paper tray, a very high-grade visual effect, a soft touch effect and color diversity can be formed on the surface of the paper tray, and some problems existing in the paper tray made of conventional materials do not need to be considered.

Description

technical field [0001] The invention relates to the technical field of production and processing, in particular to a paper support processing technology. Background technique [0002] As we all know, paper tray, also known as pulp molding, is made of carton scraps, newsprint, white pure wood pulp, etc., after pulping and blending into a slurry with a certain concentration. Vacuum adsorption molding and post-drying to form environmentally friendly paper products of different types and uses. [0003] At present, the surface of the paper tray made of general raw materials is prone to dander, discoloration, impurities, wrinkles, and cracks. For some products, dander will be adsorbed on the surface, and discoloration, impurities, wrinkles, and cracks are even more serious. It directly affects the packaging effect of the product, the surface of the paper tray is not high-grade visually and the touch is not soft, and the color of the paper tray cannot be diversified. In order to ...
