CONSULTANCY
SECTOR FOCUS 03 / CONVERTING & PACKAGING

Packaging advisory, dieline engineering & substrate sourcing.

From 3-ply and 5-ply corrugated shipper engineering to flexible barrier pouches, rotogravure prepress files, and tin/glass container procurement in Pakistan.

PACKAGING CONVERTING REALITY

Why packaging failures crush brand margins
in transit, storage, and retail shelves.

01 / CORRUGATED CRUSHING

Warehouse Box Collapse

Uncalibrated corrugated shippers made from low Bursting Factor (BF) fluting paper collapse when stacked 5-high in humid warehouses, crushing internal retail boxes and breaking bottles.

02 / BARRIER LAYER LEAKAGE

Flexible Film Delamination

Improper solvent adhesives or cheap low-density polyethylene (LDPE) sealant layers cause pouch seals to burst during cross-country freight from Karachi to upcountry markets.

03 / CYLINDER AMORTIZATION TRAPS

High Tooling on Small Runs

Startups spend PKR 400,000+ on rotogravure cylinders for 5 SKU variations, exhausting working capital before testing consumer demand in the local market.

TAILORED PACKAGING CAPABILITIES

Four Specialized Packaging Services
from Structural Spec to Quality Control.

PACKAGING MODULE 01

Corrugated Shipper Engineering & Stacking Calculation

Objectives

Engineer outer shipping boxes that withstand rough Pakistani transport, monsoon humidity, and vertical stacking without box deformity.

Scope Activities

  • Box Compression Test (BCT) & Edge Crush Test (ECT) specification
  • Flute selection (B-flute, C-flute, BC double-wall 5-ply) matching gross product weight
  • Moisture-resistant kraft liners and internal partition design for breakable items
  • Truck loading and palletization optimization (maximizing CBM utilization)

PACKAGING MODULE 02

Flexible Packaging Barrier Architecture

Objectives

Select multi-layer laminated pouch structures that protect sensitive ingredients against oxygen, light, and moisture vapor transmission.

Scope Activities

  • Laminate structure definition (e.g. PET / Met-BOPP / Poly; Kraft / Alu-foil / LLDPE)
  • Pouch format selection (stand-up pouch, 3-side seal, gusseted bag, zipper seal)
  • VFFS (Vertical Form Fill Seal) packaging machine heat-seal compatibility check
  • Gas transmission rate (WVTR & OTR) testing criteria setup

PACKAGING MODULE 03

Rigid Containers: Glass, Tin & PET Molding

Objectives

Source high-clarity bottles, hermetically sealed tin cans, and leak-proof closures from certified Pakistani and regional manufacturers.

Scope Activities

  • Neck finish standardization (28mm PCO, 38mm bericap, ROPP aluminum cap)
  • Induction heat seal (IHS) wads and leak-prevention torque testing
  • Tinplate food cans (lacquer coating inspection for acid/salt resistance)
  • Glass mold amortization evaluation and weight-lightweighting analysis
Key Deliverable Rigid Container Procurement Comparison & Leak-Test Quality Protocol.
PACKAGING MODULE 04

Prepress Color Standardization & Press Supervision

Objectives

Ensure that printing runs reproduce your exact brand colors without batch-to-batch variation across flexible and carton converters.

Scope Activities

  • Pantone Formula Guide color swatching and ink recipe verification
  • Rotogravure cylinder engraving inspection and flexo polymer plate sign-off
  • On-site press approvals at converters in Karachi SITE/Korangi and Lahore
  • Rub-resistance and tape-adhesion testing on freshly printed rolls

TYPICAL PACKAGING SECTOR CASE

Eliminating 9% Transit Breakage for a Gourmet Sauce Producer

A specialty condiment company was shipping glass sauce bottles in standard 3-ply cartons from Karachi to retail outlets in Islamabad. Jolt shocks on the National Highway resulted in regular bottle breakage, soaking cartons and ruining adjacent stock.

SourceIt re-engineered the outer shipper: upgraded to a 5-ply BC-flute carton using 150 GSM virgin kraft liner with interlocking corrugated cell dividers that isolated each bottle. Transit damage dropped to under 0.1% over the following quarter, recovering over PKR 750,000 in monthly write-offs.

COMMON QUESTIONS

Frequently Asked Questions

What is the minimum order quantity (MOQ) for custom flexible packaging?

In Pakistan, rotogravure flexible printing typically requires 300 kg to 500 kg per cylinder run (roughly 30,000 to 50,000 standard pouches). For new ventures, we identify short-run digital pouch converters or generic unprinted barrier pouches with custom label sleeves to minimize upfront capital.

How do we ensure our corrugated cartons don't sag in humidity?

We specify virgin imported or high-quality local semi-chemical kraft paper for the fluting medium and mandate a moisture-resistant sizing chemical in the corrugation starch adhesive.
