We Are PSL
Packaging strategy built on 15 years of doing the work
PSL is led by Felix Gass. 15 years in packaging, including Procter & Gamble and cross-sector work with brands from food to cosmetics to retail and private label.
PSL exists because companies keep making the same packaging mistakes: reacting to regulation instead of anticipating it, treating packaging decisions as procurement tasks instead of strategic ones, and losing months to supplier conversations that should have been resolved with a clear brief.
The person who diagnoses your situation is the same person who builds the roadmap. No handoffs. No juniors learning your industry on your budget. PSL draws on a curated network of specialists when the engagement requires additional expertise, but the strategy is always led by someone who has done this work for
15 years.
Based in Germany. Working across Europe. Independent. No material affiliations, no software partnerships, no supplier relationships that influence the advice.
What PSL is not.
Not a design agency.
We work upstream of design. By the time a designer opens a file, the strategic decisions about materials, formats, and regulatory constraints should already be made.
Not compliance software.
There are good tools for tracking EPR registrations and managing packaging data. We recommend the right ones. We do not replace them.
Not a Big Four consultancy.
We do not send a team of junior analysts to learn your industry on your budget. PSL is built for depth, not scale.
Industry partnerships
PSL is a steering committee member of the Sustainable Packaging Coalition (SPC). We contribute to EU packaging standards development and bring that regulatory intelligence directly into client work. When we advise on compliance, we know what is coming before it is published.

What We Deliver
Three integrated capabilities — strategy, structure, and execution support — deployed for brand owners, retailers, and material suppliers who need their packaging portfolio compliant, scalable, and sellable.
Packaging Strategy
We audit your packaging portfolio against PPWR, EPR, and sustainability targets — then build a prioritised roadmap your team can execute. Most clients start here.
Our capabilities
-
Portfolio audit & gap analysis (PPWR, EPR, recyclability)
-
3-horizon compliance roadmap
-
Regulatory assessment & packaging claims validation
-
LCA interpretation & target-setting
-
Board-ready strategy summaries

Workshops & decision-making frameworks
Structural Packaging Design
We design packaging structures that work on the filling line, in the supply chain, and in the consumer's hand — compliant by design, not retrofitted.
Our capabilities
-
Structural concept development & prototyping
-
Material substitution (plastic → paper, mono-material, bio-based)
-
Fit-for-use & production compatibility assessment
-
Reuse & refill format design
-
E-commerce packaging optimisation
In-house Support
Your packaging team is two people for a €500M brand. We fill the gap — without a 6-month hiring cycle. Embedded support that delivers from week one.
Our capabilities

Embedded packaging support (on-site or remote)
-
Project management & supplier coordination

Interim packaging team leadership
Our Sustainability Strategy
We hold ourselves to the same standards we set for clients.
We apply the same sustainability thinking to our own operations. Responsible sourcing, minimal waste, and honest measurement of where we stand.
Our Wins
What we have done so far: FSC-certified paper for all printed materials, CO2 offsetting for business travel, and a virtual-first setup that keeps our operational footprint low.
Coming Next
What is next: sustainable banking, the 1% for Charity commitment, full carbon neutrality, and B Corp certification as a medium-term goal.
