What is water-activated gummed kraft paper tape?

water-activated gummed kraft paper tape is a common type of adhesive tape with a layer of special starch adhesive on the back, which can maintain good adhesion performance in humid environments. This article provides a detailed introduction to wet kraft paper tape from the aspects of raw materials, production process, performance characteristics, and application fields of starch adhesive.

 

I. Raw materials for starch adhesive

 

Starch is the main raw material for making starch adhesive, which is a carbohydrate composed of multiple glucose molecules. Common starch materials include corn, potatoes, wheat, and other crops. In the process of making starch adhesive, other substances need to be added, such as water, alkaline substances, and modifiers.

 

Starch

Starch is the main raw material for making starch adhesive, which has good adhesion and viscosity and is suitable for making glue. Starch can be extracted from various plants, among which corn, potatoes, and wheat starch are the main raw materials.

 

Water

Water is the solvent of starch adhesive, which is used to dissolve starch into glue. In the process of making starch adhesive, an appropriate amount of water needs to be added according to specific conditions to achieve the best viscosity and adhesion performance.

 

Alkaline substances

Alkaline substances are auxiliary raw materials for starch adhesive, which can adjust the viscosity and stickiness of starch. Common alkaline substances include sodium hydroxide and sodium carbonate.

 

Modifiers

Modifiers are important auxiliary agents in the production of starch adhesive, which can change the physical and chemical properties of starch, improve its adhesion performance and stability. Common modifiers include sodium chloride and ammonium sulfate.

 

II. Production process of starch adhesive

 

The production process of starch adhesive mainly includes starch dissolution, heating, cooling, and viscosity adjustment.

 

Starch dissolution

Slowly add starch powder to an appropriate amount of water while stirring until the starch is completely dissolved. During the dissolution process, it is necessary to control the temperature and stirring speed of water to ensure complete dissolution of starch.

 

Heating

Heat the starch solution to a certain temperature to make it semi-transparent, while stirring to eliminate the aggregation and coagulation of starch particles, ensuring the uniformity and stability of starch adhesive.

 

Cooling

Slowly cool the heated starch adhesive solution while stirring, gradually lowering the temperature to below room temperature to make the starch adhesive more dense.

 

Viscosity adjustment

In the process of making starch adhesive, the viscosity and adhesion performance of starch adhesive can be adjusted by adding some modifiers, alkaline substances, etc., to achieve the best glue performance.

 

Performance Characteristics of Wet Water Buffalo Paper Tape

 

Wet water buffalo paper tape is widely popular due to its excellent adhesion and water resistance. Its main performance characteristics are as follows:

 

Good Adhesion

Starch adhesive has excellent adhesion and can firmly stick the tape to various materials, maintaining long-term adhesion without easy peeling or detachment.

 

Strong Water Resistance

The special starch adhesive of wet water buffalo paper tape can maintain good adhesion performance in humid environments without peeling or failure.

 

High Tear Strength

The tough texture of the buffalo paper material, combined with its adhesive properties, gives wet water buffalo paper tape high tear strength that is not easily torn or damaged.

 

Wide Range of Applications

Wet water buffalo paper tape is suitable for sealing and fixing a variety of materials and occasions, such as paper, plastic, metal, and packaging boxes.

 

IV. Application Fields of Wet Water Buffalo Paper Tape

 

Wet water buffalo paper tape has a wide range of applications, mainly used in the following areas:

 

Packaging Industry

Wet water buffalo paper tape is commonly used for sealing items in the packaging industry, such as cardboard boxes, wooden boxes, and paper bags.

 

Logistics Industry

Wet water buffalo paper tape can be used for sealing packaged items in the logistics industry to ensure that they are not damaged during transportation.

 

Construction Industry

Wet water buffalo paper tape can also be used in the construction industry for temporary closure and fixing, such as temporary closure of doors and windows, and fixing of decoration materials.

 

Home Furnishing Industry

Wet water buffalo paper tape can also be used in the home furnishing industry, such as furniture fixing and repair.

 

Artistic Field

The tough texture of the buffalo paper material makes wet water buffalo paper tape suitable for edge sealing and fixing of picture frames in the artistic field.

 

In summary, wet water buffalo paper tape, with its excellent adhesion and water resistance, has become a common packaging and fixing material in various industries. Starch adhesive, as an environmentally friendly, non-toxic, and easily degradable adhesive, is in line with the modern concept of environmental protection.
