Every Batch Tested. Every Lot Traceable.
Our Quality Assurance Plan (Doc. Ref. MAP/QAP/2026/01) governs incoming material checks, in-process control and final product certification — aligned to IS:2771 and IS:1060 standards for GeM & institutional supply.
Incoming Raw Material Inspection
No material is issued to the production floor until sampling checks are logged and signed off by the Quality Inspector.
| Component | Control Parameters | Inspection Method | Acceptance Criteria | Frequency |
|---|---|---|---|---|
| Kraft & Duplex Paper | GSM weight, moisture absorption, bursting factor (BF) | Digital GSM scale, moisture meter, hydraulic burst tester | Match PO specs (±5%); 8–12% moisture max | Every incoming reel lot |
| Gum Powder | Adhesive viscosity, lump formation | Zahn Cup No. 4 viscosity test, visual sieve test | 25–35 sec flow; smooth uniform paste | Every batch preparation |
| BOPP Film | Micron gauge, surface brightness/gloss | Digital micrometer caliper, gloss meter | 25–50 microns (±2%); zero pinholes | Random sample per roll |
| Stitching Wire | Wire gauge, zinc coating condition | Outside micrometer gauge, visual wipe test | Uniform thickness; no rust | Every fresh bundle spool |
| Bundle Patti | Strip width, tensile stretch limit | Vernier caliper, manual snap test | Standard width; no splitting under tension | Random check per delivery |
In-Process Manufacturing Inspection
Quality variables are controlled directly at each machine interface to isolate dimensional variances early.
| Machine Stage | Critical Control Points | Inspection Method | Tolerances | Frequency |
|---|---|---|---|---|
| 1. Corrugation & Cutting | Flute height, board cut size | Micrometer, calibrated steel tape | Solid B/E flute; ±2mm cut tolerance | Every 50 sheets |
| 2. Pasting Machine | Adhesive uniformity, ply alignment | Tear-separation test, edge alignment scan | No loose patches; edges fully aligned | Continuous / hourly |
| 3. Scoring & Slotting | Fold crease depth, slot profile | 90° bend test, steel layout scale | Easy bend, no fractures; centred slots | Batch start & mid-point |
| 4. Punching (Die-Cut) | Edge sharpness, lock-tab crease | Visual sweep, physical box setup | Clean corners; flaps lock tightly | Every 100 pieces |
| 5. Pinning (Stitcher) | Staple pattern & pitch | Count audit, closed-leg check | Fixed count per size; flat staples | Every bundle lot |
| 6. Strapping | Strap tension, bundle count | Manual pressure check, tally | Firm hold, no buckling; accurate count | Every strapped package |
5 boxes sampled per lot — inner/outer dimension accuracy, box bursting-strength value and joint-integrity status are verified against the client's blueprint specification using certified measuring tape and a hydraulic box burst tester.
