Recycled PET Bias Binding Tape for Underwear — Specification, Uses and Sourcing Notes
Recycled PET Bias Binding Tape for Underwear: Specification, Uses and Sourcing Notes
Recycled PET Bias Binding Tape is the version buyers specify for underwear when the base material is fixed by performance rather than by price. This entry sets out what the material actually changes, which specification to write into the tech pack, and where the cost sits — the three questions that decide whether the item passes bulk approval.
What it is
Recycled PET gives bias binding tape its drape and hand feel. In practice that means the trim behaves differently in cutting, in finishing and in wear: tighter tolerance is needed on the finished dimension. Buyers who specify the material up front avoid the most common failure — an item that looks right on the sample card and behaves differently in bulk.

- Consistency — the approved counter sample becomes the reference for every reorder.

How to specify it
- Name the base material in the tech pack, not just the item.

- Retain a golden sample at the factory and a second one with you.
