Production process of PE coated kraft paper tape!

Coated kraft paper tape is a common adhesive material widely used in packaging, box sealing, transportation and other fields. It is made by coating a special adhesive on kraft paper.

This type of tape has excellent tear resistance and adhesion, making it very popular in industrial and commercial applications.

Below, I will introduce the production process of coated kraft paper tape.

The main raw materials for coated kraft paper tape include kraft paper, adhesive, and auxiliary materials.

Kraft paper is usually made of long cellulose fibers and has good mechanical strength and flexibility.

The adhesive solution is composed of materials such as butyl rubber and resin, which can provide the adhesive and durability required for the tape. Auxiliary materials include solvents, stabilizers, and pigments.

Kraft paper coating

The first step in making coated kraft paper tape is to apply the kraft paper. Usually, the manufacturer operates on a coating machine.

The kraft paper is rolled at one end and then moved through the conveyor belt of the machine, while spraying glue from the nozzle. Nozzles are usually composed of fine holes and can evenly apply glue to the surface of the paper.

After coating, the kraft paper passes through a drying chamber to allow it to dry.

Preparation of glue solution

Glue is an important component of coated kraft paper tape. The preparation of adhesive solution usually requires mixing butyl rubber and resin together, and then adding stabilizers and solvents to make it a viscous substance.

Manufacturers usually adjust the composition of the adhesive based on the required tape specifications and performance requirements.

Tape coating

After the kraft paper is dried, the manufacturer will send it back into the coating machine for tape coating. The purpose of this coating is to provide an additional adhesive layer for the tape to better bond.

The glue is sprayed onto the other side of the paper and evenly distributed on the surface through a series of rollers. After coating, the tape is sent into an oven for baking to dry and reach the required level of adhesion.

Cutting and packaging

After coating and baking, the coated kraft paper tape needs to be cut to the required length and width. Manufacturers usually use automatic cutting machines for operation to ensure accuracy and efficiency.

The cut tape is rolled into rolls or placed on cardboard chips, and then placed in packaging bags for transportation.

Overall, the production process of coated kraft paper tape requires multiple steps and the use of professional equipment and materials.

By controlling parameters such as coating thickness, adhesive composition, and baking temperature, manufacturers can produce tape products that meet different needs. During the production process, it is necessary to strictly follow safety operating procedures and conduct quality inspections on the finished products to ensure that they meet the required standards and requirements.
