What factors are closely related to the adhesive strength of Bopp Jumbo Roll Tape?

The adhesive strength of Bopp Jumbo Roll Tape is one of its key properties in a variety of applications. Its adhesive strength is affected by many factors, the following are some of the main factors:
Adhesive type:
The chemical composition of the adhesive directly determines the interaction of the tape with the adhesion surface, thereby affecting the adhesive strength.
Different adhesives have different adhesion effects on different material surfaces.
Adhesive coating amount:
The amount of adhesive applied on the back of Bopp tape directly affects the adhesive strength.
Too much adhesive may result in too strong a tack that is difficult to release or peel off; too little adhesive may result in insufficient tack.
Characteristics of the base material (Bopp film):
The surface treatment, thickness, tensile strength and other characteristics of Bopp film will affect the adhesive strength of the tape.
The smoothness and surface energy (wetting tension) of the film are closely related to the wetting and adhesion of the adhesive.
Ambient temperature:
Sticky strength changes with temperature.
At low temperatures, the viscosity of the adhesive may decrease; at high temperatures, the viscosity may increase, which may also lead to aging or degradation of the tape.
humidity:
Humidity also has an effect on the viscosity of adhesives.
High humidity can cause the adhesive to absorb moisture, reducing the adhesive strength.
Storage conditions:
Temperature, humidity and time the tape is stored can all affect its adhesive strength.
Improper storage conditions may cause the adhesive to age or degrade.
Application surface characteristics:
The cleanliness, smoothness, chemical properties, etc. of the surface to which the tape adheres all affect the adhesive strength.
Oil, dust or other contaminants on the surface may reduce viscosity.
Pressure and contact time:
When applying tape, the pressure applied and the contact time between the tape and the surface both affect the strength of the adhesive.
Appropriate pressure and sufficient contact time help enhance the tape's adhesion to the surface.
Aging and Degradation:
Over time, tape may lose its stickiness due to aging or degradation.
Exposure to ultraviolet light, high temperatures, or other adverse environments may accelerate this process.
In summary, the adhesive strength of Bopp Jumbo Roll Tape is affected by many factors, including adhesive type, coating amount, substrate properties, ambient temperature, humidity, storage conditions, application surface properties, pressure and contact time, as well as aging and Degradation etc. These factors need to be considered when selecting and using tape to ensure the required adhesive strength is obtained.
