Problems solved by technology

[0005]At present, the domestic production of candy packaging base paper is generally based on bleached softwood pulp, supplemented by some bleached hardwood pulp, to use traditional, simple free beating or Sticky beating makes it difficult to meet customer requirements for paper evenness, smoothness, tear index and other indicators, and the damage rate of candy paper is high during automatic packaging, resulting in greater waste

Embodiment Construction

[0038] A preparation method for candy packaging base paper, comprising the steps of:

[0039] (1) Crushing: use 80% Canadian bleached leaf wood pulp, 10% Indonesian bleached hardwood pulp and 10% Xinjiang high-grade cotton pulp, and put them into 8M respectively 3 High-concentration hydraulic pulper is used for pulping, and the pulping concentration is 10-12%;

[0040] (2) Beating: After crushing, it is pumped into the raw pulp pool, and passes through three φ450 double-disc mill beating lines respectively, using a new semi-free and semi-viscous beating process, and adding suitable carboxymethyl cellulose to speed up fiber swelling. Reduce fiber cutting, improve paper tear index, tensile index and kink strength;

[0041] (3) Ingredients: After beating, it is sent to the batching tank, and additives are added in the batching tank: wet strength agent (imported epichlorohydrin) 1-4%, imported cationic starch 1-4%, aluminum sulfate 2-4%, Imported rosin emulsion 1.0-2.5%, strippi...

Abstract

The invention discloses candy wrapping body paper which is prepared from the following raw materials in percentage by weight: 80 percent of imported bleached leaf wood pulp, 10 percent of imported bleached hardwood pulp, 10 percent of domestic high-grade cotton pulp and aids. The invention also discloses a method for preparing the candy wrapping body paper. The imported bleached leaf wood pulp, the bleached hardwood pulp and the cotton pulp serve as main raw materials, and a proper amount of carboxymethylcellulose is added during pulping, so that the tearing index, tensile index and twist strength of the finished paper are improved. Therefore, the damage rate of the candy wrapping paper is lower than 0.1 percent and is far lower than 0.5 percent required in the standard when the candy wrapping paper is used for wrapping candies by a high-speed mechanical automatic wrapping machine.

Description

[0001] technical field [0002] The invention relates to the field of food packaging, in particular to a candy packaging base paper, and also relates to a preparation method of the candy packaging base paper. Background technique [0003] Candy is one of the most important snacks in China. Commonly used packaging materials for toffee include candy wrapping paper, candy wrapping plastic paper, candy wrapping metal and candy wrapping glass, etc. Among all candy wrappers, candy wrappers have the fastest growth, and candy wrappers and candy wrapper plastic paper are the cheapest, with a wide range of raw materials, and they are not as fragile as glass, nor as heavy as metal, so they are easy to carry. The International Health Organization and environmental protection experts believe that the discarded candy wrapping plastic paper may cause white pollution, which is not conducive to environmental protection, and the candy wrapping paper is easy to degrade naturally after use, and ...
