Abstract

The invention relates to a food grade konjac glucomannan adhesive tape and a preparation method thereof. The food grade konjac glucomannan adhesive tape contains an adhesive tape base material and glue sol. The preparation method comprises the following steps: preparing dissolved corn protein, dissolved nano-cellulose and mixed sol, preparing base material layer sol and the adhesive tape base material, preparing the glue sol, and preparing the food grade konjac glucomannan adhesive tape. The food grade konjac glucomannan adhesive tape has the functions of common glue and further has the characteristics that the transparency is high, the adhesive tape can be in direct contact with foods and can be degraded, and the like. Meanwhile, the change of the adhesion strength along the changes of the temperature and the time is relatively small, the adhesive tape has relatively good adhesion stability and does not have adhesive residue. The adhesive tape further has a certain waterproof functionand still has relatively good adhesive property under a relatively high humidity.

Description

technical field [0001] The invention relates to an adhesive tape and a preparation method thereof, in particular to a food-grade konjac glucomannan adhesive tape and a preparation method thereof, belonging to the technical field of daily necessities. Background technique [0002] Adhesive tape is composed of base material and adhesive, and two or more unconnected objects are connected together by bonding. Food-grade tape materials are generally used for processing, sorting, preserving, packaging or transporting food and medicine, and are suitable for direct and indirect contact with food. The adhesive tape is widely used, beautiful and simple, and convenient for mechanical operation. Environmentally friendly and degradable food-grade adhesive tape has broad market prospects. At present, there is no food-grade tape that meets the needs of the market in China, mainly because of high cost and immature technology. Adhesive tapes on the market usually use BOPP biaxially oriente...
