The packing belt is a packing material with very wide application, and plastic packing belts are most commonly used at present. The plastic packing belt is convenient to use, has thermoplasticity, and the chuck of the packing machine can soften and melt the packing belt to realize self-bonding of the packing belt. However, the plastic products are not easy to degrade, petrochemical-based raw materials are consumed in production, so that the use of the plastic products is limited, and more plastic products are forbidden. Paper materials have the characteristics of renewable, recyclable and degradable environment protection, so that the use of paper instead of plastic is an important direction of green development of materials in the packaging industry.

In addition, the paper packing belt disclosed by the invention has high mechanical strength and self-bonding performance, and improves the convenience of use, so that the paper packing belt can replace plastic packing belts.
The specific technical scheme is as follows:
the preparation method of the paper packing belt comprises the following steps:
(1) Preparing slurry: selecting one or more of cotton pulp, hemp pulp and needle pulp, adding water for disintegration to prepare pulp with the mass concentration of 3-8%, pulping, and adding 0.3-1.0% of PAE reinforcing agent;
(2) And (3) base material papermaking: diluting the slurry prepared in the step (1) to 0.2-0.6% of mass concentration by adding water, carrying out papermaking by using a cylinder paper machine, wherein the number of cylinder formers is 6-10, and the substrate ration is 200-500 g/m 2 The water absorption value is not lower than 1g/g;
(3) Cutting a base material: cutting the paper substrate manufactured in the step (2) into strips with the width of 6-30 mm by using a cutting machine, and then rolling into a disc shape;
(4) Dipping: carrying out gum dipping and drying treatment on the strip-shaped paper base material prepared in the step (3); the temperature of the glue solution is 65-95 ℃ when the glue is dipped, and the absorption capacity of the glue solution is not less than 1g/g; the drying temperature is 110-125 ℃, and the water content after drying is lower than 10%.
In the step (1), beating is carried out until the beating degree is 30-55 DEG SR and the wet weight of the fiber is 15-25 g.
In the step (4), the glue solution comprises 5-10% of PVA, 0.005-0.01% of glycerin, 0.025-0.05% of sodium borate and the balance of water.
The molecular weight of polyvinyl alcohol is 12-25 ten thousand, the degree of hydrolysis is 85-95%, glycerin is used as plasticizer, and borate is used as modifier.
