About Circular Blueprint

Packaging science, translated into practical judgement.

I’m Hosein Pouriman, PhD—a senior packaging specialist and polymer engineer based in New Zealand. Circular Blueprint is where I publish evidence-led packaging insight for people making difficult decisions across Australia and New Zealand.

Why this site exists

Packaging advice becomes dangerous when it becomes too simple.

A resin code does not describe a recovery system. A supplier declaration does not settle a finished-pack claim. A lower material weight is not automatically a lower-impact result. Circular Blueprint exists to examine the connections that disappear when packaging is reduced to a slogan.

From polymer films to FMCG systems

The science came first. Industry made the questions harder.

My doctoral research at the University of Auckland examined monolayer polymeric films for food-packaging applications. It involved materials, formulation, processing, structure and performance—the technical foundation beneath many packaging decisions.

Work in specialist materials development and large FMCG environments added the parts that laboratory work cannot answer alone: production trials, supplier capability, product protection, commercial constraints, sustainability reporting, labelling, implementation and the consequences of getting a change wrong at scale.

That combination shapes Circular Blueprint. I am interested in the point where material science meets the factory, the market, the recovery system and the evidence a business can actually defend.

What informs the work

A packaging decision seen from more than one angle.

The perspective behind Circular Blueprint comes from applied work across packaging R&D, sustainability and FMCG operations in the Australia and New Zealand market.

Polymer and film science

Materials, formulation, extrusion, barriers, mechanical behaviour and the limits of simplified material labels.

Packaging development

New-product development, specifications, suppliers, technical assessment and packaging-change implementation.

Manufacturing reality

Plant trials, line performance, conversion constraints, quality risks and what survives outside a presentation.

Sustainability systems

Material reduction, recycle-ready transitions, carbon considerations and the trade-offs behind circularity claims.

Compliance and evidence

ANZ requirements, APCO reporting, Australasian Recycling Label implementation, claim support and decision records.

Commercial judgement

Cost and complexity reduction considered alongside product protection, supply resilience and operational risk.

How I approach packaging

Evidence over slogans.

Good packaging work rarely produces a perfect answer. It produces a clearer decision: grounded in the product, honest about uncertainty and explicit about the trade-offs the business is accepting.

01

Start with the job of the pack

Product protection, safety, shelf life, manufacturing and distribution are the starting conditions—not obstacles added later.

02

Separate fact from assumption

Requirements, guidance, supplier statements, test results and internal preferences should not be treated as the same kind of evidence.

03

Keep the full system visible

A pack exists inside supply chains, factories, households and recovery systems. Optimising one part can damage another.

04

Leave a decision trail

The reasoning, source date, uncertainty and ownership of the next step should remain understandable after the meeting is over.

Circular Blueprint today

An author-led knowledge resource, kept deliberately low-key.

The website is maintained primarily to publish useful packaging analysis and preserve a body of practical ANZ knowledge. It is not a public checkout or an always-open consultancy. Selected professional work may occasionally be considered where availability, scope and conflict checks allow, under a separate written agreement.

Corrections, source suggestions and clearly defined professional correspondence are welcome. Please do not send confidential information with an initial message.

Explore the publication

Four connected views of packaging.

The archive follows the same questions that shape real packaging work: what applies, what performs, what the recovery system can handle and what the change costs.

01

The useful work is in the detail.
