BRAZIL MARKET LOCALIZATION · FLEXIBLE PACKAGING · MANUFACTURING · COMMERCIALIZATION
A single-serve electrolyte drink mix was being localized for Brazil with new market-specific formulas and a compressed commercialization timeline. The incumbent global packaging structure did not meet company material requirements for the target market and required replacement.
At the same time, Brazil’s high-temperature, high-humidity environment introduced uncertainty around the barrier performance needed to support product stability.
The challenge was to establish a new packaging system that met material requirements, protected the product, ran on existing manufacturing equipment, supported the regulatory timeline, and could be commercialized without delaying launch.
ROLE
Packaging technical lead
Material recommendation · Trial strategy & execution · Manufacturing assessment · Analytical testing · Final packaging recommendation
DEFINING THE PROBLEM / 01
MATERIAL
Incumbent structure required replacement under company material requirements.
PRODUCT
New market-specific formulas; product/package stability not yet established.
ENVIRONMENT
High-temperature, high-humidity target-market conditions increased the importance of barrier performance.
MANUFACTURING
Solution needed to run on existing packaging equipment without significant capital modification.
TIMING
Trials and stability work needed to progress in parallel with the regulatory and commercialization schedule.
The packaging strategy had to address material requirements, barrier performance, manufacturability, consumer usability, stability, and speed to market simultaneously.
MATERIAL STRATEGY / 02
Several commercially available film structures were screened against material, barrier, manufacturing, and timing requirements.
A high-barrier PET/aluminum laminate emerged as the strongest candidate because it aligned with the material requirement and was commercially available without a separate supplier-development program.
Because the required barrier level had not yet been confirmed through stability testing, two candidate aluminum gauges—9 μm and 12 μm—were carried into initial trials and stability work.
CANDIDATE A
9 μm
Advanced to trial + stability
CANDIDATE B
12 μm
Advanced to trial + stability
I recommended carrying both candidate structures forward to reduce commercialization risk while generating the data required for the final material decision.
ENGINEERING THE OPENING FEATURE / 03
Adding an equipment-based tear notch or microperforation would have required capital investment and additional implementation lead time.
Existing production equipment
Capital + lead-time constraint
Supplier-applied laser scoring
No major packaging-line modification
PACKAGING-MATERIAL SOLUTION
Laser scoring provided a consumer opening feature without requiring modification of the existing packaging line.
CONCEPTUAL SCORE-ZONE EVALUATION
Multiple score concepts were evaluated for tearability and repeat-position consistency.
“I evaluated multiple laser-score patterns for tearability and specified the final score location relative to the package repeat to maintain consistent placement during production.”
LEARN SMALL, THEN SCALE / 04
An initial trial was conducted on a small single-lane machine to understand how the PET-based structure behaved relative to the incumbent cellophane-based control. Both aluminum gauges were evaluated.
SEALING BEHAVIOR
Temperature and pressure requirements
MACHINABILITY
Film handling and equipment interaction
FILLING PERFORMANCE
Package interaction with product flow and filling
PACKAGE INTEGRITY
Consistent seals and leak prevention
PRODUCTION CAPABILITY
Operating conditions and achievable production speed
OBSERVED
The PET-based structure behaved differently from the incumbent material. Film friction emerged as an important processing variable.
ENGINEERING RESPONSE
A slip agent was added to reduce coefficient of friction and improve machinability.
The 9 μm and 12 μm structures demonstrated similar overall manufacturing performance, while the thicker structure required greater sealing temperature and pressure.
STARTING THE STABILITY CLOCK / 05
Material produced during the initial single-lane trial was used to begin stability testing while commercial manufacturing development continued.
Initial trial
Candidate packages produced
Stability initiated
Regulatory timeline supported
PARALLEL WORKSTREAM
Commercial manufacturing development continued simultaneously.
WHY PARALLELIZE
This approach allowed product/package uncertainty to begin being retired without waiting for commercial-scale manufacturing development to finish.
ANALYTICAL TESTING
Performed pH and water-activity analytical testing as part of the evaluation.
COMMERCIAL-SCALE VALIDATION / 06
Learning from the initial trial was carried into commercial production trials.
The new structure required different operating conditions from the incumbent material. Production speed was reduced relative to the control to establish reliable sealing and package integrity at commercial scale.
OPERATING PRINCIPLE
Incumbent settings
Structure-specific operating window
Manufacturing conditions were balanced against the primary requirement: consistently producing a functional, integral package.
FINAL RECOMMENDATION / 07
Based on combined manufacturing and stability results, I recommended the 9 μm aluminum structure as the long-term configuration.
Commercially available high-barrier laminate
Validated material gauge
Laser-scored opening feature
Adjusted film slip characteristics
Established manufacturing parameters

RECOMMENDED COMMERCIAL PACKAGING SYSTEM
OUTCOME / 08
01
New packaging structure established for the target market
02
Major packaging-line capital modification avoided
03
Consumer opening solution integrated through packaging-material design
04
Stability material generated early enough to support the regulatory timeline
05
Commercial manufacturing conditions established
06
Long-term material configuration selected
07
Successful on-time market launch
ENGINEERING PRINCIPLE
The project began with uncertainty around barrier requirements, product stability, material behavior, sealing conditions, and commercial manufacturability. The development strategy used parallel testing, staged scale-up, and evidence-based decisions to resolve those uncertainties while protecting the commercialization timeline.
