Tape Comparisons.   ![Tapes so many](https://www.globalplasticsheeting.com/hs-fs/hubfs/Tapes%20so%20many.jpg?width=348&name=Tapes%20so%20many.jpg)   When looking to seal plastic sheeting, the environment that it is being used in is what will dictate the best tape to select. Is there moisture, high humidity, sunshine, or water? Is the tape sealing two over-lapping sheet's of a crawl space liner in a moist basement? Or are we talking about sealing a tear in a slip and slide tarp. Is the tape going to be in the sun? For this post, we are going to introduce the films that Global Plastic Sheeting favors. ## **The best Over-All Tape:** Our most versatile tape, that is **water-proof, fish safe, and has UV** to protect from the sun's rays, **[Ultra Perm](https://www.globalplasticsheeting.com/ultra-perm-tape-waterproof-tape?hsLang=en-us)** is the best selection. This tape is EXCEPTIONALLY STICKY. When it is put down, it's not coming up.  If you have a tug of war with two sheets of plastic, the plastic will break before the tape let's go (in most cases). ## **The Best Tape for a Crawl Space Liner or Vapor Barrier:** If you are sealing a crawl space liner or vapor barrier,** [Vapor Seaming Tape](https://www.globalplasticsheeting.com/tapes?hsLang=en-us)** is a great choice. it is chemical resistant- not that you have chemicals in your basement- and has a nice strong hold. It will resist the moisture coming up from the ground.  If you want a double sided (two-sided) tape for this application, the **[Butyl Seal Tape](https://www.globalplasticsheeting.com/butyl-seal-tape?hsLang=en-us) **is a great choice. It is waterproof, aggressive, flexible and non-hardening. ## **The Best Tape That is Fire Retardant:** ****There are two choices when it comes to the tape being flame retardant. [Polyken 225 FR](https://www.globalplasticsheeting.com/polyken-225-fr-meets-far-2585-a?hsLang=en-us)****  meets FAR 25.853 (a)  and is used in the aerospace industry. It is used in areas where flame retardancy is required.  225 FR seals duct work, fiberglass insulation and more. [****Global CFRP Tape****](https://www.globalplasticsheeting.com/global-cfrp-tape?hsLang=en-us) is also fire retardant, and virtually leaves no adhesive residue on applications lasting up to 60 days. ## **The Best Waterproof and/or Fish Safe Tape?** [Ultra Perm](https://www.globalplasticsheeting.com/ultra-perm-tape-waterproof-tape?hsLang=en-us) is the clear cut choice here. It can be used in your pond, slip and slide tarp, and anywhere there is water.  This beast of a tape grabs on, and doesn't let go!
