In any shrink wrapping project, there are two main types of tape used. The first one is what we call a shrink/patch tape or tear tape, because of its pinked or serrated edge for easy tear capabilities.
The other tape that we use in the shrink wrapping process is a preservation or hull/attachment tape. As an example, this tape is what is typically used to attach shrink film to the hulls of boats for shipping purposes.
Shrink Wrap Solutions preservation tape is a high-end tape that can be applied to non-porous surfaces for extended periods and then be removed without leaving an adhesive residue.
Shrink/Patch Tape is stocked in 2", 4" and 6" widths by 180' in length, and is 7 mil thick. Each roll has an easy tear pinked/serrated edge and is individually wrapped in shrink wrap. The tape contains UV inhibitors in the adhesive.
Preservation tapes come in a variety of widths in 108' (36 yds.) lengths. This high end, high quality tape is 9 mil in thickness and will require a cutting blade at times to assist in cutting this tape from the roll. They are used primarily for attaching films, such as shrink film to non-porous, hard surfaces.
