Sealant Tapes

Sealant tapes are used to seal the bagging film to the tool or part. They are very pliable and similar in texture to “chewing gum”. Most sealant tapes are butyl-based material which will stick to most bagging films (except silicone which is self-sealing) and to most fiberglass, aluminum, and plate glass tools. Sealant tapes should be tacky enough to allow for ease of sealing while maintain the vacuum bag able to remove cleanly from the part or tool.
