Great product ### ⭐⭐⭐⭐⭐ This 12 mil tape works great! *by G***K on January 17, 2026* This tape is great. I have bought 5 rolls of this tape and it sticks to plastic excellent. It cuts easy with a knife or razor blade. Great for crawl spaces and high ceilings in pole barns where plastic needs to be secured. Great value for the money. I purchased a roll of white tape from another vendor and it would not stick to the plastic lime this one does so I returned it. ## Frequently Bought Together - CrawlSpace-DIY - Vapor Barrier Tape, [3 Pack] 4" x 180' PE 12mm Polyethylene Tape, Moisture Barrier Seal and Seam, Insulation Tape for Crawl Space Vapor Barrier, Marine & More - Taiyin 1" Vapor Barrier Christmas Tree Clips Plastic Nylon Rivet Clips White Furniture Assembly Shelves Retainer for Crawlspace Barrier Poly Liners, Covers and Encapsulations(500 Pcs) - CrawlSpace-DIY - Butyl Tape - 1.5" x 100' - 3 Pack Butyl Sealant Home Repair Tape, Butyl Rubber for Boat Sealing RV Sealant Tape Vapor Barrier Window, Glass Roof Patching - Waterproof --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/508376168-crawlspace-diy-vapor-barrier-tape-3-pack-4-x-180](https://www.desertcart.hr/products/508376168-crawlspace-diy-vapor-barrier-tape-3-pack-4-x-180) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-19*
