Paper-based cold-chain packaging
Develop fiber structures, insulation, and barriers that protect temperature-sensitive products. Evaluate thermal performance alongside condensation, wet strength, and manufacturing requirements.
Sustainable materials for demanding packaging applications.
We develop packaging materials where sustainability, product protection, and manufacturing requirements are difficult to reconcile—from paper for the cold chain to recovered textile fibers.
Led by senior specialists with experience at Amazon, PepsiCo, Mars, and International Paper. Meet our specialists.
The material problems we work on
Our work spans fiber science, barriers, insulation, and material processing. These are three areas where we apply that expertise.
Material redesign for SB 54
Evaluate material changes for plastic reduction and design for recyclability or compostability under California’s SB 54. Determine how each option affects product protection, processing, and cost before committing to a redesign.
Requirements and exclusions depend on the material and producer. CalRecycle’s SB 54 guidance.
Recovered textiles and alternative fibers
Develop cushioning, insulation, and protective packaging from alternative feedstocks, including recovered textiles. Assess performance, feedstock consistency, processing compatibility, and end-of-life options together.
Meet your technical specialists
Work directly with experts who have spent decades developing materials and bringing packaging into commercial production.
Company experience and career accomplishments refer to the individual experts.
How we develop a material
A senior specialist leads the work from the initial requirements through trials and production planning.
Set the requirements
Define what the package must withstand, how it will be made, and what it can cost. Establish measurable performance and end-of-life requirements.
Develop and validate
Evaluate material structures and feedstocks against those requirements. Plan and lead trials with your team, suppliers, and testing partners.
Prepare for production
Translate trial results into material specifications and supplier requirements. Address processing constraints before scaling up.
Experience that reaches commercial scale.

WinterMarch helped us turn a complicated packaging redesign into a clear technical plan. Their team connected material science, supplier qualification, line trials, and sustainability claims so we could make decisions with evidence instead of assumptions. The cost reduction paid for the engagement many times over.
