Problems solved by technology

When twisted wrapping paper based on long-fiber soft base paper is used as wrapping paper for popsicles, due to the low temperature environment, the moisture absorbed by the paper will freeze, making the wrapping paper very hard, and it is easy to be brittle and broken, resulting in the popsicles being exposed This shortens the shelf life and cannot meet the needs of popsicle packaging

Embodiment 1

[0031] A kind of anti-freezing twisting paper is prepared through the following steps:

[0032] 1. Base paper substrate: long-fiber leaf-increasing pulp base paper is selected as the paper substrate. The weight of paper is 24-45 grams per square meter, and the technical indicators of base paper are as follows:

[0033] Moisture content 5.2%

[0034] Transverse tear strength 3.5KN / m

[0035] Longitudinal tear strength 3.3KN / m

[0036] Transverse tensile strength 25N / 15mm

[0037] The longitudinal tensile strength is 47N / 15mm.

[0038] 2. Printing: Printing is carried out on the upper surface of the paper base layer, that is, the vacuum aluminized layer.

[0039] 3. Penetration: Prepare the penetrant according to the formula of 24% glycerin, 16% D-mannitol, 4% sorbitol, and 56% water, and use the dip coating method to infiltrate, that is, the paper is completely immersed in the penetrant, and the paper is soaked at 120 m / The paper passes through the penetrating agent at a...

Abstract

The invention discloses a freeze-resistant twisted paper and a production method thereof and belongs to the field of packaging. The freeze-resistant twisted paper comprises a paper base layer, a printing layer disposed on the upper surface of the paper base layer, and a wax layer disposed on the lower surface of the paper base layer. The paper base layer is subjected to osmotic treatment. A penetrant comprises 30% of glycerin, 20% of D-mannitol, 3% of sorbitol and 47% of water. The freeze-resistant twisted paper solves the problem that the common wrapping paper is easy to crack and hardens after absorbing water.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a freeze-resistant twisting paper and a production process thereof. Background technique [0002] Popsicle is a favorite food for men, women and children, especially in summer, it is a popular cold food for relieving summer heat. At present, the most widely used popsicle packaging paper is mainly based on plastic film (PVC, PE) or paper-plastic composite packaging film. After use, waste packaging paper will pollute the environment and cause permanent damage to water and soil. In recent years, domestic research and development of degradable twist wrapping paper based on long-fiber soft base paper has the characteristics of exquisite printing, soft paper, high kink strength, no rebound after molding, good sealing, moisture-proof and odor-proof, and can be degraded , No harmful releases and other advantages. However, since the popsicle production process is carried out in a state of -22°C...
