Adhesive starch granules in paper boxes, when mixed uniformly with water at a certain temperature, absorb surrounding moisture and gradually swell under the catalysis of caustic soda, reaching the gelatinization temperature through several expansions. As the temperature rises, starch granules begin to disperse and gradually break down into smaller pieces. Upon immersion into the face and core papers, they start to bond, requiring an initial viscosity (achieved primarily through the action of caustic soda and borax solutions). With the increase in temperature, the moisture in the starch granules evaporates and is partially absorbed by the face and core papers, enabling a faster achievement of the initial viscosity. The adhesive connects the inner paper, core paper, corrugated paper, and face paper into a cohesive unit, thereby achieving the bonding purpose.

Characteristics of Paper Box Adhesives:

1. Excellent Penetration: Good penetration is a challenge for paper products that are difficult to adhere to. No Moisture and Color Change: Corrugated boxes do not regain moisture and change color after forming and drying, and are resistant to compression and mildew.

2. Cost Reduction: With less competition in watchmaking and high bonding strength, we can lower your production costs, creating significant economic benefits for your company and thereby realizing self-worth.

3. Bonding Stability: The adhesive strength exceeds that of other products. The hygiene standards meet the requirements of the Chinese health department and enable export packaging for storage in humid environments (such as refrigeration) and sea transportation.

4. Long Life Storage for Box Glue: Dragon Brand reinforcing agent is suitable for various glue-making machinery and equipment, ensuring that the glue produced does not thin out or become thin in high-temperature environments. It can be stored for 7-10 days.
