Making outline
- Extrude/calender selected tab-adhesive thermoplastic charge into controlled thin film and qualify bonded metal/laminate trial interfaces
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
- Current memory-first method needs source and compatibility review.
