CASE STUDIES

Packaging in Practice: Real Industrial Challenges Solved

How SRM Enterprises engineered custom fitments, heavy-duty boxes, and rapid fulfilment packs for automotive, industrial, and logistics leaders.
Automotive & Auto Components

Zero-Scratch Transit Packaging for Machined Transmission Gears

The Challenge:

Vibration during inter-facility freight caused parts to collide inside standard boxes, leading to micro-dents on gear teeth and reject rates of over 3.2%.

The Solution:

SRM engineered custom 10mm high-density EPE foam interlocking matrix trays housed inside heavy-duty 5-ply corrugated outer boxes with reinforced corner posts.

Illustrative Packaging Application:

Transit reject rate dropped to 0.0%, packing cycle time reduced by 22%, and the reusable foam inserts cut recurring material spend by 18%.

High-Compression Heavy-Duty Packaging for 85kg Cast Iron Pump Assemblies

The Challenge:

Conventional packaging suffered box bulging, bottom tear-out, and humidity damage during prolonged monsoon transit in standard trucks.

The Solution:

SRM designed a 7-ply heavy-duty container with a heavy bottom deck, reinforced corrugated edge protectors, and high-tensile PET strapping.

Illustrative Packaging Application:

Supported 3-high warehouse stacking without box deformation, eliminated transit moisture staining, and replaced costly wooden crates.

Rapid Pack-Out Optimization for a Multi-Node 3PL Fulfilment Centre

The Challenge:

Coordinating six different suppliers caused tape shortages, box dimension mismatches, and bottleneck delays during peak sale dispatches.

The Solution:

SRM established a single-source supply agreement with weekly scheduled replenishment of 12 standard die-cut box sizes, pre-printed BOPP tapes, and air bubble rolls.

Illustrative Packaging Application:

Consolidated invoicing into a single vendor, achieved 100% on-time stock availability, and accelerated dispatch speed by 15%.

3-Ply vs 5-Ply Corrugated Boxes: How to Choose the Right Wall Thickness

A practical engineering guide comparing burst strength, stacking capacity, weight limits, and cost trade-offs between single-wall and double-wall boxes.

Key Rules of Thumb:
  • Use 3-ply (single wall) for lightweight products up to 8–10 kg with internal support
  • Use 5-ply (double wall) for payloads between 10 kg and 35 kg requiring stackability
  • Pay attention to paper GSM and flute type (B, C, or E) alongside ply count
  • Consider climate humidity when determining required burst strength

How to Choose the Right EPE Foam Thickness & Density for Component Protection

Learn how to calculate cushioning requirements based on product drop height, part fragility (G-factor), and weight distribution.

Key Rules of Thumb:
  • 0.5mm – 2mm foam rolls are ideal for surface scratch protection and wrapping
  • 5mm – 20mm sheets provide excellent mid-level vibration and side cushioning
  • 25mm+ custom die-cut foam fitments protect heavy precision hardware from drop shocks
  • Match foam density (20 kg/m³ to 32 kg/m³) to the static load bearing pressure

Air Bubble Wrap vs EPE Foam: Which Protective Packaging Performs Best?

An objective head-to-head comparison of bubble wrap and EPE foam across shock absorption, puncture resistance, dust-free performance, and cost.

Key Rules of Thumb:
  • Air bubble is flexible, transparent, and great for void fill and odd-shaped retail products
  • EPE foam provides superior repeated impact resistance and will not pop under static loads
  • EPE foam produces zero abrasive friction against sensitive painted and polished finishes
  • Laminated foam + bubble pouches combine the surface softness of foam with bubble cushioning
