Generally, when the tape is produced or cut into strips, air is often trapped between the adhesive layer and the adhesive layer, resulting in the appearance of air bubbles. Sometimes when the machine is properly controlled, the surface of the tape will be flat after a period of time when the air escapes. Some are unable to escape, resulting in the appearance of bubbles.

    In addition, there are the following two problems for the use of 3M tape:

1. The factors that cause the aging of 3M tape are:

1. Oxygen.

2. Ultraviolet rays (sunlight).

3. Metal, especially brass or rust.

4. Bleach.

5. Plasticizers.

Under the long-term influence of the above factors, the tape will deteriorate, soften, cure, and lose its viscosity.

2. How long is the service life and duration of 3M tape?

    For a tape supplier, all tapes are coated with pressure-sensitive adhesive for a certain substrate. The pressure-sensitive adhesive is a viscoelastic polymer. In terms of materials, all materials are exposed to oxygen, ultraviolet rays, dust, solvents, moisture Air, etc., will be more or less affected, so 3M will give advice on the appropriate use period, storage environment and conditions, packaging specifications, etc., according to the performance characteristics of different tapes, in order to maintain equivalent quality and performance.
