Problems solved by technology

The existing food packaging containers are directly sterilized and made into food packaging containers suitable for food, but there are still many inconveniences. For example, the existing food packaging containers cannot withstand high temperatures and cannot be microwaved. Heating, the heat insulation effect is not good; for example, when a paper cup is filled with hot drinks, it is easy to burn your hands; when it is filled with cold drinks, there will be water droplets on the outer wall of the paper cup

Embodiment Construction

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0031] A kind of preparation method of food packaging container of the present embodiment, comprises the following steps:

[0032] 1) Prepare paper: use pulp to prepare food packaging paper;

[0033] 2) Printing the foaming glue: printing the foaming glue on one side of the food packaging paper by a screen printing machine or a gravure printing machine;

[0034] 3) Slitting: cutting the paper into the shape of packaging paper;

[0035] 4) Forming: use the packaging paper obtained by cutting to make food packaging containers and sterilize them, and the foaming glue is located on the outer surface of the side walls of the formed food packaging containers;

[0036] 5) Foaming: After the formed food packaging containe...

Abstract

The invention relates to a food packaging container and a manufacturing method thereof. A foamed layer is arranged on the outer surface of the side wall of the food packaging container and comprises a supporting layer and a fuzz layer. The supporting layer is integrally connected with the outer side wall of the food packaging container, the fuzz layer is integrally connected to the supporting layer, and the density of the fuzz layer is smaller than that of the supporting layer. The foamed layer is arranged on the outer surface of the side wall of the food packaging container, and therefore the effect of heat insulation can be achieved.

Description

technical field [0001] The invention relates to the technical field of food paper packaging, in particular to a food packaging container and a preparation method thereof. Background technique [0002] At present, in the field of food packaging, for the sake of environmental protection and saving, food packaging containers are gradually used instead of plastic packaging. The existing food packaging containers are directly sterilized and made into food packaging containers suitable for food, but there are still many inconveniences. For example, the existing food packaging containers cannot withstand high temperatures and cannot be microwaved. Heating, the heat insulation effect is not good; for example, when a paper cup is filled with hot drinks, it is easy to burn your hands; when it is filled with cold drinks, there will be water droplets on the outer wall of the paper cup. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
