Does the stickiness of packing tape decrease over time?

Will the stickiness of sealing tape decrease over time?
The stickiness of sealing tape will decrease over time.

1. Cause Analysis
1. Glue Aging
The stickiness of sealing tape mainly comes from the adhesive component in its glue. Over time, the glue will gradually age. In this process, the molecular structure of the adhesive may change, resulting in a decrease in its stickiness.

Environmental factors such as temperature, humidity, and light can also accelerate the aging of glue. High temperature will soften the glue and reduce its stickiness; high humidity will cause the glue to absorb moisture and affect its stickiness; ultraviolet rays in light will destroy the molecular structure of the glue and make its performance worse.

2. Tape Surface Contamination
During storage and use, the surface of the sealing tape may be affected by pollutants such as dust, oil, and moisture. These pollutants will cover the adhesive surface of the tape, reducing the contact area between the glue and the adhered object, resulting in a decrease in stickiness.

3. Deformation of the tape under pressure
If the sealing tape is subjected to heavy pressure or folding for a long time, the base material and glue of the tape may be deformed. This deformation will affect the uniformity of the glue distribution, thereby reducing the stickiness of the tape.
