Preparation method of packaging paper for vegetable-based safe and environment-friendly food

Abstract

The invention discloses a preparation method of packaging paper for a vegetable-based safe and environment-friendly food. The preparation method comprises the following steps: smashing fresh cabbage and fresh celery, and adding water while stirring to prepare pulp; adding a proper amount of sweet potato starch, konjac gum and the like; performing ultrasonic oscillation to form paper-making pulp. Compared with an ordinary mechanical stirring manner, the preparation method has the advantages that an ultrasonic technical process is simple and is convenient to operate, the pulping efficiency is increased, the production energy consumption is lowered, and meanwhile the prepared pulp has superior strength and mechanical performance. Cinnamyl aldehyde and chitosan are complexed into mixed filler through a series of treatment methods, and the mixed filler is added into paper pulp, so that the antibacterial activity of paper can be improved remarkably; moreover, all components are pure natural components, so that the paper is safe and reliable. The packaging paper produced by the method is made from safe and reliable components, is solid and durable, has high strength, is safe to human body, and can be directly applied to packages of foods.

Description

technical field [0001] The invention relates to the technical field of wrapping paper, in particular to a method for preparing vegetable-based wrapping paper for safe and environment-friendly food.
