Seam Tapes

To maximize your film’s versatility and minimize installation times, GSI offers a full line of tape sealants for our lightweight films and for non critical applications. Proper seaming of films and liners is critical to their performance. To be certain that you are selecting the correct method for your project, contact us. We will discuss the options with you and let you decide which method is best for you.

Poly Seal® is a 2 sided adhesive tape used for joining two panels of polyethylene sheeting together by overlapping the edges eliminating an exposed tape joint. Pol Seal® is non hardening and permanently flexible. It is a good choice for long term applications where shear strengths are relatively low.

Transit-Seal® is recommended for applications requiring strong and quick adhesion to polyethylene sheeting. It has a black HDPE 5 mil backing with 1.5 mil permanent acrylic adhesive on a 90# release paper. Its adhesion gains strength with time making it well suited to long-term applications.

Moldable Sealant® and G25® tapes are comprised of a synthetic elastomeric adhesive which bonds instantly in a wide range of temperatures to most plastics, metals and concrete. Moldable Sealant® is a 2 sided tape used for blind overlap seams. The G25® has a special multi-polymer alloy film backing making it resistant to sunlight, thermal expansion, abrasion and puncture. Moldable Sealant® and G25® provide a very aggressive bond to polyethylene sheeting. They are non-hardening and permanently flexible. They work well for long term applications where shear stresses are low.
