Every packaging line has heroes. They don’t wear capes—just gloves, hairnets, and pedometer-busting shoes. In a busy Ahmedabad 3PL serving FMCG and marketplace sellers, the night shift led by Priya Patel had one recurring villain: bundles breaking and flaps popping during staging. Tape held only so long. Rope looked messy and cut into corrugation. Steel strap solved strength but brought rust worries, sharp edges, and slowdowns.
The answer arrived as something disarmingly simple: TruBond PP Strap with round clips paired to their semi-automatic tabletop strappers. What changed wasn’t merely the bundle—it was the shift’s rhythm, safety, and confidence.
Meet the Team, Meet the Problem
Priya’s crew pushes 8,000–10,000 bundles per night—mixed cartons, return parcels, and promotional kitting that can’t justify heavy PET or steel. They needed fast, quiet, safe bundling that held through multiple handlings and a bumpy last-mile—without leaving rust streaks or torn flaps.
Before the change, the team logged an average 2.6% rework from bundle loosening and crushed edges. Operators avoided steel after two minor nicks in a week. Morale dipped; throughput followed.
“We didn’t need a bigger tool. We needed the right strap—something light, quick, and safe to use nonstop,” Priya recalls.
What They Changed: PP Strap & Round Clip, Set Up Right
TruBond’s PP strap (polypropylene) is purpose-built for light and medium loads where volume and ergonomics matter.
Working spec window (typical):
Widths: 9, 12, 15/16, 19 mm
Thickness: 0.5–0.9 mm (grade-dependent)
Surface: Embossed for feed reliability and grip; smooth available
Break Strength: up to ~300–450 kg depending on width/grade
Jointing: Heat-seal/friction weld on semi/auto machines; round metal clips for manual/portable tensioners
Coil Core: 200/406 mm ID to suit tabletop and arch strappers
Color: Natural/white, black, custom tints for line coding
Temperature Window: Best in ambient operations; choose PET for high heat/long dwell or heavy palletization
Sustainability: Recyclable PP; low dust feed; clean presentation
Why round clips? They’re fast to place with manual tensioners, form a reliable crimp joint on PP, and keep the bundle safe when a machine can’t reach the staging area. For machine bundling, the built-in heat seal eliminates clips altogether—great for throughput.
Priya’s team standardized two SKUs: 12 mm × 0.6 mm for parcel bundles and 16 mm × 0.7 mm for heavier FMCG cases. Machines were tuned for consistent friction-weld times, and mobile trolleys carried hand tensioners + round clips to off-line zones.
Human Outcomes: Safer Hands, Quieter Floors, Faster Wrap-Up
The first week told the story.
Rework rate fell from 2.6% to 0.9% as bundles survived consolidation and van loading.
Throughput improved by 11–14% because PP strap fed smoothly and welded predictably—no reset after every third bundle.
Operator safety & comfort shot up. No sharp edges, no recoil, and significantly less noise than steel.
Presentation improved—white PP with neat welds looked “retail ready,” which mattered to brand audits.
“The round-clip kits gave us freedom in overflow zones. The machine lines were faster, and the manual teams could still keep pace,” says Yash, the line lead on aisle 3.
“Our QA stopped flagging crushed edges. Honestly, the floor just feels calmer.”
Where PP Strap Wins (and Where You Should Choose PET Instead)
To make the best choice, match strap to load, journey, and dwell:
PP Strap sweet spot
Applications: Carton bundling, print stacks, apparel sets, lightweight pallets, e-commerce returns, kitting.
Machines: Tabletop and arch strappers (semi/auto).
Benefits: Lower cost/coil, fast sealing, operator-friendly, recyclable, clean look.
When PET is smarter
Applications: Heavy pallets (ceramics, metals, timber), long sea journeys, outdoor staging, where tension retention under temperature swings matters.
Why: PET’s elongation recovery and higher break strength keep loads tight for longer. Use serrated clips or heat seal on auto lines.
Think of PP as your high-volume bundling athlete and PET as your long-haul bodyguard.

Audit the mix: Sort by weight and route. Put <15 kg bundles and short-haul cartons into PP 12 mm; heavier bundles into PP 16 mm (or PET if >40 kg and long dwell).
Match the joint: Heat-seal on machines; round clips for manual zones. Keep clip width equal to strap width.
Tune the weld: Fix friction time and pressure; print settings by SKU at each station.
Edge protection: Add small corner pieces where cartons crush easily—cheap insurance.
Color code: Use white PP for parcels, tinted PP for priority or returns. Visual control speeds bays.
Train for tension: Two-hand method on manual tools; quick pull test after every fifth bundle for the first week.
Track & improve: Log rework and meters/100 bundles. If rework >1%, check weld time or move that SKU to 16 mm.
The crew laminated this on a board at the end of aisle 2. Rework stayed under 1% through monsoon—a first.
Why TruBond for PP Strap & Round Clips
Machine-friendly embossing & tight gauge control for consistent feed and weld.
Round clips and strap sized as a system, so your joint efficiency is predictable.
Coil options for every table/arch strapper common in Gujarat plants.
Batch labels & documentation for audits, plus quick service and training from a local team.
Upgrade path: If your loads evolve, TruBond maps an easy step to PET strap and battery tools—same partner, new strength class.
In other words, it’s not just a coil. It’s how your shift wins.
