🔍 Our Quality Control Process

Precision at Every Step. Excellence in Every Piece.

At SR Flexopack Limited, quality control is more than a checklist — it’s a discipline embedded in every layer of our operation. We maintain a comprehensive, multi-stage Quality Control (QC) Process to ensure that each product we manufacture — whether it’s a neck board, back board, poly bag, or export carton — meets the highest standards of performance, consistency, and compliance.

Our QC protocols are designed to serve clients in garments, food, FMCG, and industrial export sectors, ensuring that all products align with international buyer requirements and withstand real-world logistics.

✅ 1. Raw Material Inspection

Every batch of raw materials (paperboard, kraft liner, duplex, PE-coated sheets, poly rolls) is inspected upon arrival for:

  • GSM accuracy (± tolerance range)

  • Moisture content

  • Color and surface smoothness

  • Odor and contamination

  • PE/lamination adhesion (if applicable)

📌 Only approved materials move forward to production.

✅ 2. In-Process Quality Checks

During the production process, on-site supervisors and quality technicians conduct hourly checks to monitor:

  • Die-cut accuracy (shape, angle, size)

  • Printing registration & color alignment

  • Folding, creasing, and perforation quality

  • Adhesive bonding and seal strength

  • Size tolerance (width, length, thickness)

📋 Any deviation results in immediate adjustment or rejection before mass production continues.

✅ 3. Final Product Inspection

Before packaging and dispatch, we run random sampling from each production lot based on AQL (Acceptable Quality Limit) standards to verify:

  • Visual defects

  • Structural rigidity and edge finishing

  • Print correctness (buyer logo, carton marking, barcode)

  • Count accuracy and packing configuration

  • Batch traceability & production date labeling

📦 Defective units are removed and reworked before delivery clearance.

✅ 4. Special Performance Testing (for applicable products)

For products such as export cartons and freezer-safe packaging, we perform:

  • Bursting strength test

  • Box compression test (BCT)

  • Water resistance/moisture test

  • Cold-chain endurance simulation (for frozen food cartons)

✅ 5. Pre-Dispatch Final QC Clearance

Once products are packed, a final QC report is generated. The dispatch team receives clearance only after:

  • QC head signs the batch release

  • Labels and markings are matched against the buyer’s tech pack

  • Final count is verified against the purchase order

📑 Documentation & Traceability

Each product batch is backed by:

  • QC Inspection Checklist

  • Raw Material Approval Sheet

  • Final Batch QC Report

  • Sample Verification Record

  • Buyer PO and Tech Pack cross-check

This allows us to track every shipment for accountability, audits, and long-term client trust.

🎯 Why Our QC Process Stands Out

  • Dedicated QA/QC department with trained inspectors

  • Compliance with AQL and international inspection standards

  • Buyer-specific QC customization (Zara, H&M, Walmart, etc.)

  • Sample retention for future reference

  • Fast resolution for any client concern

At SR Flexopack, we believe that great packaging isn’t just produced — it’s perfected.
