Introduction

In the packaging material industry, speed and precision go hand in hand. Every roll of film, every batch of paper, every printed label has to be weighed, recorded, and dispatched accurately often across multiple shifts and dispatch points.

However, for many packaging factories, weighing and labeling remain manual tasks. Operators weigh materials on basic scales, write weights on paper, and enter them later into an Excel sheet or ERP. This delay often leads to errors, mismatched entries, and poor inventory visibility.

This case study explores how one packaging material manufacturer transformed its production and dispatch process using an industrial weighing scale with printer integrated with a custom-built Weighing ERP system eliminating manual errors, boosting productivity, and achieving real-time traceability.

The Client: A Leading Packaging Material Manufacturer

The client is one of India’s largest producers of flexible packaging films and laminated rolls used by FMCG, food, and pharmaceutical brands. With a daily production output of over 25 tons and multiple dispatch lines, they faced increasing challenges in maintaining weight accuracy, batch tracking, and dispatch documentation.

Their plant operated three main stages:

Extrusion & Lamination Line – where rolls of film were produced.

Printing & Slitting Line – where film rolls were customized for clients.

Dispatch Section – where finished rolls were weighed, labeled, and loaded for transport.

Each roll needed a printed label showing weight, batch number, roll number, date, operator name, and QR code for traceability.

The Challenge

Before automation, the company faced several recurring problems:

Manual Recording Errors – Operators recorded weights in registers, which were later entered manually into ERP. Mistakes and mismatched entries were common.

Labeling Delays – Labels were printed separately using office printers, taking 30-40 minutes per batch.

Traceability Gaps – During audits, linking a roll’s physical label to its ERP record was difficult.

Inventory Inaccuracy – Dispatch teams couldn’t get live stock data, leading to duplicate entries or missing rolls.

Compliance Risk – Without Legal Metrology compliant labels, the process lacked standardization and audit readiness.

They needed a solution that could directly link weighing, labelling, and ERP entry in one automated flow.

The Solution: Industrial Weighing Scale with Printer + Weighing ERP Integration

The team at Punit Instrument Private Limited implemented a customized weighing automation system built around two key components:

Industrial Label Printing Weighing Scale – A robust platform scale with a built-in thermal printer.

“Earlier we spent hours writing weights and waiting for labels. Now it’s automatic. We just weigh, stick, and move to the next roll. It’s made our shifts smoother.” – Senior Operator, Dispatch Line 2

Even the quality control team benefited. They could scan any label and see full production and calibration data instantly from the ERP dashboard.

The ROI Breakdown

The client’s cost-benefit analysis showed:

40% reduction in manpower required for weighing and labeling

95% reduction in labeling errors

100% audit-ready traceability

25% faster dispatch turnover

Payback period: 6.5 months

Beyond numbers, the biggest gain was peace of mind every product that left the factory was accurately weighed, labelled, and digitally traceable.

The Future: Expanding Across Units

After the successful pilot, the company decided to replicate the system across all their packaging units. They are now connecting additional stations like raw material intake, quality inspection, and finished goods warehouse to the same Weighing ERP, creating a fully connected plant ecosystem.

The next upgrade will include:

Cloud-based reporting
