Production Process of Water-Activated Kraft Paper Tape！

Water-activated kraft paper tape is a special type of tape with a layer of wet kraft paper on its back. The wet kraft paper possesses excellent flexibility and tear resistance, making water-activated kraft paper tape widely used in packaging and sealing applications. Below is a detailed description of the production process of water-activated kraft paper tape.

 

Raw Material Preparation:

The main raw materials for water-activated kraft paper tape include adhesive, wet kraft paper, and auxiliary materials. The adhesive is typically a viscous bonding agent made from natural rubber, synthetic rubber, or acrylic materials. Wet kraft paper is cellulose material extracted from buffalo hide, which exhibits high toughness and abrasion resistance. Auxiliary materials include plasticizers, fillers, stabilizers, etc.

 

Wet Kraft Paper Treatment:

Wet kraft paper needs to undergo treatment to improve its processability and adhesive properties. Firstly, the buffalo hide is cleaned and soaked to remove impurities and dirt. Then, the buffalo hide is immersed in specific chemicals to soften the cellulose fibers and enhance their flexibility. Next, the treated buffalo hide is cut and ground to obtain the desired wet kraft paper.

 

Coating:

During the coating process, the adhesive is evenly applied to the back of the wet kraft paper. This can be achieved using a coating machine where the wet kraft paper is fed through a set of rollers, and the adhesive is applied to the rollers and then transferred onto the back of the wet kraft paper. The coating machine has a precise control system to ensure uniform adhesive application.

 

Drying (Continued):

The drying process of water-activated kraft paper tape requires special attention to ensure the quality of the paper and adhesive is not compromised. Control of drying temperature and time is crucial, as excessive temperature may cause the paper to become brittle or the adhesive to lose its stickiness, while prolonged drying time may result in the loss of flexibility in the wet kraft paper.

 

Cutting:

The dried water-activated kraft paper tape is cut using a cutting machine. The cutting machine utilizes sharp blades to cut the tape into the desired width and length. The cutting machine typically has an automated control system to achieve precise cutting according to predetermined specifications.

 

Packaging:

After the cutting process, water-activated kraft paper tape needs to be packaged for storage, transportation, and sale. The packaging process typically involves the following steps:

 

Reeling: The cut water-activated kraft paper tape is wound onto specific reels or cores. This can be done by placing the tape on a large reel and using an automated or semi-automated device to wind it up.

 

Packaging Material Preparation: Prior to packaging, packaging materials such as plastic film, cardboard boxes, or plastic bags need to be prepared. These packaging materials are used to protect the water-activated kraft paper tape from contamination, moisture, and physical damage.

 

Packaging: The reeled water-activated kraft paper tape is placed into the prepared packaging materials. Usually, a roll of tape is packaged as a smaller roll or placed into a tape dispenser box. This process can be done manually or by using automated packaging machines.

 

Labeling and Tags: After packaging, the water-activated kraft paper tape may have labels and tags attached, such as product models, specifications, production dates, and brand information. These labels and tags help users better understand the tape's performance and uses.

 

Quality Control:

Quality control is crucial in the production process of water-activated kraft paper tape. Manufacturers typically conduct strict quality inspections, including testing of raw materials, inspection of wet kraft paper, sampling checks of coating quality, testing of drying effectiveness, and inspection of the final product's appearance and performance. These control measures aim to ensure consistent quality standards of water-activated kraft paper tape and meet customer requirements and expectations.

 

Special Treatments (Optional):

Some water-activated kraft paper tapes may undergo additional special treatments to enhance their performance or meet specific needs. For example, tapes can be treated for waterproofing, heat resistance, or increased weather resistance. These treatments are often carried out based on specific application areas or customer requirements.

 

The production process of water-activated kraft paper tape includes several steps, such as raw material preparation, wet kraft paper treatment, coating, drying, cutting, and packaging. Through strict quality control and optional special treatments, manufacturers can ensure that water-activated kraft paper tape possesses high-quality adhesive performance and durability. Water-activated kraft paper tape finds wide applications, particularly in packaging and sealing tasks that require flexibility and tear resistance. Manufacturers continuously improve and innovate production processes to meet market demands and provide better product performance.
