Cut from the same lot as the sample you approve, with the peel figure measured rather than quoted. Typical use is general purpose closures, bags, packaging and display mounting. Service temperature runs -20 °C to 80 °C.
Each piece weighs about 0.4 g; 1,000 pieces to a carton. Tolerance on width is ±0.5 mm, on die-cut profile ±0.3 mm.

- Sold by the roll, carton or pallet — mixed widths allowed.
- EXW Xiamen, FOB or CIF to your port.
- T/T 30% deposit, balance against copy of B/L.
- Sample orders ship by courier in 7 days.
Choosing this construction
The adhesive decides whether this product works, not the hook. Clean and dry the surface, apply with a roller at roughly 10 N/cm², and leave it 24 hours before loading — peel measured immediately after application reads about 60% of its final value. On polypropylene, polyethylene or heavy powder coat, test a sample first or specify the rubber version.
Common questions
What is 20 mm hook and loop used for?
At 20 mm this construction is normally specified for general closures, bags, packaging, display mounting and low-load bundling. The width does not change the peel per unit width much, but narrower tape engages fewer hooks at the edge, which is where peeling starts — so if the joint opens repeatedly, go up one width rather than up one grade.
Will it stick to plastic crates or powder-coated metal?
Powder coat usually works with the heavy-tack acrylic, applied with firm roller pressure. Polypropylene and polyethylene have very low surface energy and are the most common field failure — test a sample on the actual substrate before production, or ask us to quote the rubber adhesive version.
How long before I can load it?
Twenty-four hours at room temperature for full strength. Peel measured twenty minutes after application is typically 55–65% of the final value, so a QC pull test done straight off the line will always read low and is not a valid reject criterion.
What is the minimum order and lead time?
Minimum order for this item is 5,000 pcs. Production runs 15–25 days after sample approval, with samples typically shipped in 7 days.
