How to identify the pros and cons of Teflon tape

1. The tape with poor tape retention force will open after packaging for a period of time (between 20 minutes and 1 hour), and cannot be pasted again. (more pronounced in cooler environments and windy dry conditions).

2. Inferior Teflon film tape has poor toughness and is easy to break: Inferior tape is easy to break and has low strength, which is mainly related to the quality of Teflon film.

In addition, the tape paper tubes produced by regular enterprises are made of high-density paper tubes, with no paper scraps on the cut surface, and the tapes with a thickness of less than 100 meters are 3 mm, and those with a thickness of more than 100 meters are 4-5 mm, while small enterprises are Thick paper tubes are used for blind production, usually with a thickness of 5-7 mm, which is relatively large in appearance, but the thickness of the glue is clearly compared. Therefore, when choosing the tape, you must clearly see the width and thickness of the tape. Also note that because the inferior tape is mixed with a lot of impurities, there is an imperceptible gap between the tapes when the tape is rolled in strips, so the same number of meters is the case. The lower volume will be relatively large, thereby deceiving consumers.
