Embodiment 1

[0032] The edible and soluble composite film packaging material is composed of starch, polysaccharide, protein and alcohols. In this embodiment, the starch is potato starch or corn starch or wheat starch, and the polysaccharide is xanthan gum sugar or chitosan or glucomannan or seaweed polysaccharide.

[0033] The preparation method comprises the following process steps:

[0034] A, material preparation: take starch, polysaccharide, protein and alcohols and put them into containers respectively, and set them aside;

[0035] B. Modification: Add maleic anhydride or acetic anhydride or sodium trimetaphosphate with a dosage of 15% into containers containing starch and polysaccharides respectively, and carry out general modification, that is, esterification, to starch and polysaccharides. Sex time 2 hours, spare;

[0036] C. Glue making:

[0037] The preparation of nail nails, said nail nails include the following components and weight percentages, the total amount is 100%, the...

Embodiment 2

[0046] The present embodiment is basically the same as Example 1, the difference being: the preparation of the nail gel: get 250 grams of the modified starch, 220 grams of the modified polysaccharide, 80 grams of collagen, 75 grams of zein, casein 75 grams of protein, 150 grams of glycerin, 150 grams of sorbitol;

[0047] The preparation of the second glue: get 250 grams of the polysaccharide, 250 grams of sodium carboxymethylcellulose, 100 grams of collagen, 100 grams of casein, 150 grams of glycerin, and 150 grams of sorbitol.

Embodiment 3

[0049] The present embodiment is basically the same as Example 1, the difference being: the preparation of the nail gel: get 220 grams of the modified starch, 250 grams of the modified polysaccharide, 75 grams of collagen, 80 grams of zein, casein 80 grams of protein, 175 grams of glycerin, 120 grams of sorbitol;

[0050] The preparation of the second glue: get 150 grams of the polysaccharide, 300 grams of sodium carboxymethylcellulose, 75 grams of collagen, 75 grams of casein, 200 grams of glycerin, and 200 grams of sorbitol.

Abstract

The invention discloses a preparation method for an edible and soluble composite film packing material. The preparation method comprises the following process steps of: A, preparing materials; B, modifying, namely adding a modifier into a container in which starch and polysaccharide are accommodated for later use; C, preparing glue, namely preparing glue A by placing modified starch, modified polysaccharide, collagen, zein, casein, glycerin and sorbitol into a reaction kettle, heating, stirring and cooling for later use, and preparing glue B by placing the polysaccharide, sodium carboxymethylcellulose, the collagen, the casein, the glycerin and the sorbitol into the reaction kettle and performing the steps; and D, preparing a film, namely preparing a film A by coating the glue A and the glue B on a film forming machine, starting the film forming machine for processing, adhering the prepared film A and a film B to form a whole body, and thus obtaining the edible and soluble composite film packing material. The preparation method is normalized, convenient to operate and energy-saving, and can be widely applied to the fields of packages of drink, food, condiments, vegetables and fruit, and the like, emission is reduced, and industrialized batch production can be easily formed.

Description

technical field [0001] The invention relates to a preparation method of packaging materials, in particular to a preparation method of edible and soluble composite film packaging materials. Background technique [0002] Traditional packaging materials have been used in food packaging for a long time. Statistics show that with the prosperity of commodities and the rapid rise of the packaging industry, the world's per capita consumption of packaging materials has reached 145kg / year, and packaging materials account for 100% of the annual waste generated worldwide. 1 / 4-1 / 3. Materials, including packaging materials, are the foundation and forerunner of national economic and social development, and are listed as the three pillars of modern high-tech alongside energy and information. On the one hand, packaging materials promote the development of social economy and the progress of human civilization, but on the other hand, they consume a lot of resources and energy, and emit a lot ...
