Problems solved by technology

[0002] The commonly used food packaging materials are mainly paper-plastic boards, tinplate plates, and aluminum alloy plates; these food packaging materials can be made into food packaging containers such as cans, bottles, and cans, but paper-plastic boards have the disadvantages of low strength and easy deformation. Although tinplate and aluminum alloy have better strength, the cost is also higher; there is no food packaging plate with lower cost and higher strength in the market.

Abstract

A board used for packaging food is composed of paper board and coated layer. It is prepared through preparing coating material from food-class unsaturated polyester, solidifying agent, promoter, dibutylester and filler, and finally coating it on paper board. Its advantages are low cost, high strength and not deforming easily.

Description

Technical field: [0001] The invention relates to a board and a preparation method thereof, in particular to a board for food packaging and a preparation method thereof. Background technique: [0002] The commonly used food packaging materials are mainly paper-plastic boards, tinplate plates, and aluminum alloy plates; these food packaging materials can be made into food packaging containers such as cans, bottles, and cans, but paper-plastic boards have the disadvantages of low strength and easy deformation. Although tinplate and aluminum alloy have better strength, the cost is also higher; there is no food packaging plate with lower cost and higher strength in the market. Invention content: [0003] The object of the present invention is to overcome the above-mentioned defects, provide a food packaging plate with lower cost and higher strength, and provide a preparation method of the plate. [0004] To achieve the above object, the present invention adopts the following t...
