Embodiment 1

[0024] The antifreeze agent was prepared in the following proportions: glycerin 50%, antifreeze peptide 0.1%, D-sorbitol 2%, ethanol 7%, and the balance was water.

[0025] Choose long-fiber leaf-increasing pulp base paper as the base layer of the wrapping paper, and immerse the base layer of the wrapping paper in the antifreeze treatment agent at a speed of 100-150 m / min through a roll; after drying, the upper surface of the base layer is coated with gloss The oil layer is coated with a wax layer on the lower surface, and the low-temperature frozen food outer wrapping paper is prepared after cutting.

Embodiment 2

[0027] The antifreeze agent was prepared in the following proportions: glycerin 50%, antifreeze peptide 0.3%, D-sorbitol 2%, ethanol 7%, and the balance was water.

[0028] Choose long-fiber leaf-increasing pulp base paper as the base layer of the wrapping paper, and immerse the base layer of the wrapping paper in the antifreeze treatment agent at a speed of 100-150 m / min through a roll; after drying, the upper surface of the base layer is coated with gloss The oil layer is coated with a wax layer on the lower surface, and the low-temperature frozen food outer wrapping paper is prepared after cutting.

Embodiment 3

[0030] The antifreeze agent was prepared in the following proportions: glycerin 50%, antifreeze peptide 0.5%, D-sorbitol 2%, ethanol 7%, and the balance was water.

[0031] Choose long-fiber leaf-increasing pulp base paper as the base layer of the wrapping paper, and immerse the base layer of the wrapping paper in the antifreeze treatment agent at a speed of 100-150 m / min through a roll; after drying, the upper surface of the base layer is coated with gloss The oil layer is coated with a wax layer on the lower surface, and the low-temperature frozen food outer wrapping paper is prepared after cutting.

Abstract

The invention provides an anti-freezing treatment agent and an application method thereof. The anti-freezing treatment agent provided by the invention is prepared from the following components by masspercentage: 30-65% of glycerin, 0.2-0.6% of anti-freezing peptide, 1-3% of D-sorbitol, 5-10% of ethanol and the balance water. According to the technical scheme, the anti-freezing peptide is added toimprove the physical properties of food packaging paper in a long-term low-temperature frozen state and / or under the condition of large temperature difference change, so that the food packaging papermaintains good paper performance and is prevented from being broken due to brittle denaturation, and the quality stability of packaged contents is guaranteed.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to an antifreeze treatment agent and an application method thereof. Background technique [0002] Food packaging is a large player in the packaging industry, accounting for about 70% of the entire packaging industry. Food packaging paper is a packaging product with pulp and cardboard as the main raw material. It needs to meet the requirements of non-toxic, oil-resistant, waterproof, moisture-proof, and airtight, and the paper used for packaging food meets the safety requirements of food packaging. Because food packaging paper is in direct contact with food, and most of its packaging is directly imported food, the most basic requirement for food packaging paper is to meet the requirements of food hygiene. Secondly, according to the different requirements for the use of food packaging paper, there are also Relevant technical standards must be met. [0003] Due to the introduc...
