PURTERIA Vapor Barrier Tape, 9 Mil, 3.6 in x 180 ft

PURTERIA Vapor Barrier Tape is a white polyethylene seam tape sized for joining and sealing vapor-barrier liners. Its 3.6-inch width, 180-foot roll, and release liner are aimed at longer sealing runs, though customer feedback reports mixed adhesion on vapor-barrier material.

At a glance

A 180-foot roll is intended for seams and sealing work on poly liners, vapor barriers, insulation and underlayment.
The listing describes a release liner that peels away to help dispense the tape.
The manufacturer describes the tape as waterproof and weatherproof, but these are listing claims rather than independently verified performance.

Customer feedback highlights perceived quality and ease of use, but adhesion and value for money draw mixed reactions. For a tape intended for plastic-barrier seams, the adhesion reports matter because performance depends on the specific liner and surface. The rating distribution skews positive, though ratings alone do not explain the differing experiences.

Positive themes

Customers describe the tape as high quality and easy to use.

Mixed feedback

Adhesion feedback is mixed, with reports ranging from strong sticking to poor bonding on vapor-barrier material.
Value feedback is divided, with some considering it worth the price and others finding it costly.
