Printing ECO friendly degradable kraft paper tape technology!

With the continuous increase in environmental awareness, more and more consumers are beginning to pay attention to the environmental impact of products. As a commonly used packaging material, the use of tape is also increasing. However, traditional plastic tape has caused serious pollution to the environment. In order to solve this problem, the printing of non-adhesive biodegradable kraft paper tape has been widely used in daily life and industry as an environmentally friendly material. This article will detail the production process of this tape, including design, engraving, printing, backing, release, adhesive coating, rewinding, slitting, and other steps.

 

Design:

Firstly, the designer needs to design the appearance and patterns of the product, which will be printed on the surface of the tape. The designer needs to use professional design software to create these patterns and save them as vector graphic files, such as .eps or .ai files.

 

Engraving:

After the design is completed, the pattern needs to be transferred to the engraving plate. The engraving plate is a template-like item used for printing and can be used multiple times. The process of making the engraving plate is to engrave the designed pattern on photosensitive resin or rubber through photolithography or direct carving. The quality of the engraving plate directly affects the quality of the printed product, so fine production is necessary.

 

Printing:

Printing is one of the most critical links in the production of tape. During the printing process, the engraving plate is placed on the plate frame of the printing press, and the printing press transfers ink onto the engraving plate and then prints the pattern on the kraft paper tape. The printing process requires strict control of temperature, humidity, ink concentration, printing speed, and other parameters to ensure the stability and consistency of the quality of the printed product.

 

Backing:

Backing refers to applying a layer of adhesive on the back of the kraft paper tape after printing is completed. The backing adhesive can increase the viscosity of the kraft paper tape, preventing it from sliding or falling off during use. The selection of backing adhesive and coating technology is one of the key factors affecting the quality of the tape.

 

Release:

After the backing is completed, the kraft paper tape needs to be taken off from the printing press. Release refers to the process of separating the tape from the engraving plate. Professional release liquid is needed to process the engraving plate to separate it from the tape and prevent the viscosity of the tape from being affected.

 

Adhesive Coating:

After release, a layer of glue needs to be applied to the back of the tape. The quality and technology of the adhesive coating directly affect the service life and quality of the tape. Generally, different types of glue need to be used for different scenarios and requirements. For example, high-temperature glue is needed for tapes used in high-temperature environments.

 

Rewinding:

After adhesive coating, the kraft paper tape needs to be rewound. Rewinding is the process of re-rolling the tape from a wider to narrower paper roll, making it easier to store and use. Tension and roll diameter need to be controlled during rewinding to avoid damage and deformation to the tape.

 

Slitting:

The last step is slitting, which is also the final process of producing paper tape. In the slitting process, the rewound paper tape is cut into tapes of different widths and lengths. The slitting process requires ensuring cutting accuracy and speed, and labeling and packaging according to customer requirements.

 

In summary, this article provides a detailed introduction to the production process of biodegradable paper tape, including design plate, engraving, printing, release liner, adhesive coating, rewinding, and slitting. With the increasing awareness of environmental protection, biodegradable paper tape as an environmentally friendly material has been widely used in daily life and industrial fields.
