Will the stickiness of sealing tape decrease over time?
The stickiness of sealing tape will decrease over time.
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.
1. Storage conditions
Good storage conditions can slow down the rate at which the stickiness of the sealing tape decreases. For example, if the tape is stored in a dry, cool, ventilated environment, avoiding direct sunlight and high temperature and humidity, the service life of the tape can be extended.
Avoid contact between the tape and chemicals to prevent the chemicals from corroding the glue and affecting the stickiness.
2. Tape quality
The stickiness of sealing tapes of different brands and qualities will change over time to different degrees. Good quality tapes usually use high-quality glue and base materials, with better aging resistance and stickiness retention.
3. Use environment
When using sealing tape, if the surface of the object to be adhered is rough, unclean or oily, it will affect the stickiness of the tape. At the same time, if the temperature, humidity and other conditions in the use environment change greatly, it will also accelerate the reduction of the tape's viscosity.
Sealing tape is available in a variety of different specifications and thicknesses, and the appropriate size can be selected according to different packaging needs. Most modern sealing tapes use water-based adhesives, which are environmentally friendly and non-toxic and will not cause harm to the human body or the environment. This tape is usually made of polypropylene film as the base material and coated with adhesive. It has good adhesion and durability, which can ensure the sealing performance of the packaging box.
High-quality sealing tape has good wear resistance, water resistance and weather resistance, and can maintain good performance under various environmental conditions. For ease of use, sealing tape is usually designed to be easy to tear, without the use of tools such as knives, which improves work efficiency. In family life, sealing tape can be used to wrap gifts, organize items, etc. It is a very practical daily necessity.
