Use this list when you compare quotes or sign off a lab dip for footwear, bags, or small leather goods. It keeps your team aligned on what must appear on the purchase order so bulk matches the swatch you approved. For company background and service scope, read the About Bintang Karunia Abadi page, then return to the site home for an overview of markets we supply.
1. Confirm width, thickness, and yield
Record usable width in millimeters, total thickness, and whether the article is sold by meter, yard, or kilogram. Note the pattern repeat if the grain is directional. Ask how many pairs or panels you should expect per roll so cutting rooms can plan spreads without surprises.
2. Match abrasion and flex tests to the end use
State the Martindale or Wyzenbeek target, cold flex needs for winter boots, and any brand RSL on restricted substances. If you only need city-office handbags, do not pay for motor-grade UV packages. If you need both, write two separate line items so the mill does not average them into one weak spec.
3. Lock color with light source and lot rules
Name the standard illuminant for approvals, attach a digital Lab value if you use one, and define how many Delta E units you allow between lots. Decide who holds the master swatch and how many days the supplier has to answer a shade challenge after goods land.
4. Choose backing and hand-feel intentionally
Knit, woven, or foam backings change stitch tear and stitch sink on sewing lines. Call out peel strength on bonded constructions and whether you need flame lamination compatibility. For deeper material science on PU versus PVC, see our earlier note on PU leather vs PVC leather.
5. Plan packing, rolls, and shelf life
Specify core diameter, maximum roll weight your lift tables accept, and whether rolls ship face-in or face-out. Ask for UV wrap or kraft only if your warehouse needs it. Add humidity limits if you store goods near the coast.
6. Align delivery slots with cutting calendars
Share your factory blackout dates and the minimum buffer you want between arrival and cutting. If you run multiple colors on one style, ask whether partial shipments are allowed or if you need a single lot per color.
7. Name the commercial owner at BKA
Put one technical contact and one logistics contact on the PO. When you are ready to request strike-offs against this checklist, open the products section for article families, then use contact with your PO draft attached.
