The production of the environmentally friendly packaging material of the present invention is mainly made of more than half of the recycled fiber plant shell material and other main materials, crushed and mixed into a raw material body, and then 'water, edible oil, active interface agent, Milk powder, pulp, stone powder, etc. are mixed into fluid-like secondary materials, and liquid agents such as adhesives are put into each other and stirred, | Stirred into a raw material mass, processed by extrusion and discharge, and pressed into a sheet to form a thin plate The flake-shaped raw material sheet is dried, glued, and then dried and processed to make an edible packaging material that is edible and safe and convenient for stamping and shaping of different containers, and has the purpose of environmental protection and packaging for recycling. Due to the rising awareness of environmental protection, in order to make the objects on the earth sustainable, various resources with environmental protection concepts have been continuously developed and researched. H The packaging materials for food are restricted by the need for hygienic and safe food packaging. 1P Therefore, recyclable packaging containers or metal boxes, trays, etc. can be reused by cleaning and are classified as environmentally friendly packaging materials, but packaging materials packed in large quantities, If such materials are used for packaging, it is not only costly, but also needs to be cleaned, and there are too many containers of the same object, which will result in the waste of another resource. Therefore, in the design and use of edible packaging, it is usually used Designed to be discarded or recycled afterwards, making it relatively environmentally friendly and effective. Traditional food packaging containers such as lunch boxes, plates, bowls, etc. are more commonly made of paper, and the raw materials are The materials used are mainly new wood pulp. After being processed into cardboard, it is pressed into various packaging containers according to the mold. Therefore, it is said to be environmentally friendly. Recyclable beating and reuse, or direct incineration will not affect environmental protection. However, because wood pulp is usually obtained by felling trees, the direct acts of environmental persecution are the most fouling diseases, and the production process and the added items in the middle need to be new.
