Smart Weighing Scale Automation for Plastic Manufacturers

Jisha Polyfilm is a shrink film manufacturing company based in Gujarat, India, specializing in the production of LD Shrink Film rolls of various sizes and micron thicknesses. The company operates continuous production lines where every roll is individually tracked, labeled, and dispatched to customers.

As production volumes grew and product variety expanded — spanning multiple roll sizes (inches) and micron specifications — managing production records, printing accurate stickers for each roll, and dispatching the right rolls to the right customers became increasingly complex and error-prone when done manually.

The Challenge

Jisha Polyfilm faced several operational challenges across their manufacturing and dispatch workflow. As production volumes increased, the manual processes became a bottleneck:

  • Manually writing or typing product labels/stickers for every roll produced
  • No standardized format for roll identification (size, micron, weight, roll no.)
  • Difficulty tracking how many rolls were produced per manufacturing order
  • No automated barcode system for tracking individual rolls
  • Manual calculation of net weight (gross weight minus core weight)
  • No way to quickly scan and verify roll data at the time of dispatch
  • Lack of centralized dispatch scan sheets grouping rolls by size
  • Errors in micron/size labeling leading to incorrect dispatches
  • No audit trail of how many stickers were printed per roll/order
  • Workers had to manually convert sizes between mm and inches
  • No cross-verification between production records and dispatch records
Jisha Polyfilm Requirements

Requirements

To overcome these challenges, Jisha Polyfilm required a comprehensive digital solution:

  • Automatic generation of unique roll reference numbers (SM/XXXXX)
  • Barcode-embedded production stickers with roll number, size, micron, gross/core/net weight
  • Auto-calculation of net weight (gross minus core)
  • Size entry in both mm and inches with automatic conversion
  • Roll sequence tracking per manufacturing order and per size
  • A barcode scan-based dispatch sheet that groups rolls by size
  • Per-section weight totals (gross, core, net) on dispatch sheets
  • Print log tracking — know how many times each sticker was printed
  • Integration with Odoo Manufacturing Orders (MRP)

The Solution

Micra Digital developed a customized Odoo 19 Manufacturing extension for Jisha Polyfilm to digitize roll tracking, labeling, and dispatch:

  • Small Sticker Module: Auto-generated roll numbers, roll specifications, barcodes, and compact 3×2-inch PDF labels.
  • Smart Size & Micron Conversion: Real-time bidirectional conversion between mm/inches and micron/gauge.
  • Production Stickers: Custom large-format labels with size codes, batch numbers, and customer-specific details.
  • Barcode Scan & Dispatch: Scan rolls, validate records, group by size, and generate dispatch sheets with weight totals.
  • Print Audit Trail: Track every sticker print with timestamps and complete print history.
  • Roll Sequence Tracking: Automatically suggests the next roll number based on the Manufacturing Order and size.
  • The Result
