Frame the nylon–polypropylene trade-off at component level

The record turns weight, adjustability and assembly behavior into separate fields that can be checked on the same finished route.

Product priority
What to record: Targeted component mass, hand, tail drape and adjustment frequency
Project detail: ____________________
How to confirm: Rank requirements on the approved product brief

Tape identity
What to record: Fiber, weave, width, thickness, mass per length, finish and code
Project detail: ____________________
How to confirm: Condition, measure and retain each candidate

Adjuster route
What to record: Buckle identity, bar path, layer count and tail orientation
Project detail: ____________________
How to confirm: Photograph the threaded production assembly

Folded return
What to record: Fold length, seam pattern, needle, thread and edge finish
Project detail: ____________________
How to confirm: Make matched returns and open one specimen for inspection

Component mass
What to record: Finished tape length plus attached hardware and reinforcement
Project detail: ____________________
How to confirm: Weigh complete assemblies on the same basis

Use observations
What to record: Feed, holding, edge wear, hole growth, recovery and tail position
Project detail: ____________________
How to confirm: Cycle both assemblies with one agreed sequence

Lower polymer density does not by itself predict the mass, thickness or performance of a finished strap made with a different weave.
