Recyclable High-Barrier Film Patent Snapshot 2026
The recyclable high-barrier film patent space is tightly concentrated, with Dow Global Technologies and Rohm & Haas jointly accounting for the dominant share of filings across a corpus of 9 patent families. Activity peaked in 2021 and has since eased, signaling a field in decline where the foundational IP positions have largely been established.
Dow and Rohm & Haas hold commanding positions in a highly concentrated field
The recyclable high-barrier film patent evidence snapshot is dominated by two applicants — Dow Global Technologies LLC and Rohm & Haas Co — each holding 11 patent records at the top of the ranking, well ahead of third-ranked Oerlemans Packaging BV at 7 patent records.
The top five filers account for 94% of the combined total across the ranked applicants visible in this query, indicating an exceptionally narrow competitive field with little room for mid-tier challengers. The gap between the top two and the remaining applicants is substantial.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | Dow Global Technologies LLC | 11 | |
| 2 | ROHM & HAAS CO | 11 | |
| 3 | Oerlemans Packaging BV | 7 | |
| 4 | Suzhou Zijin Plastic | 1 | |

| 7 | ROHM & HAAS CO (50 00) | 1 |
The entrenched positions of Dow and Rohm & Haas — reinforced by their well-documented co-filing relationship — suggest that the core polymer coating and laminate architectures for recyclable high-barrier films have been largely claimed. New entrants face a high barrier to differentiated IP in the main technology branches.
Patent publication typically lags filing by 18–24 months, so activity in 2024–2026 may be under-represented in this corpus. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity peaked in 2021; layered laminates dominate the technology mix
Annual filing volumes and technology branch composition together reveal a field that surged briefly around 2020–2021 before retreating, with B32B layered products and laminates remaining the visible technical route throughout.
Annual filing trend
Filings were absent before 2020, rose to a peak of 5 records in 2021, then fell sharply to zero in 2022 and 2023, with only a single record appearing in 2024. The 2024–2026 window is subject to publication lag and may not yet fully reflect recent activity.

B32B (layered products and laminates) is the leading branch, followed by C08J (polymer processing and solutions) and C09D (coatings, paints and inks). B65D (containers and packaging) has a smaller but meaningful share, while B29D (specific plastic articles) represents only a single patent record — the sparsest branch in the corpus.

Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Dow Global Technologies LLC
Dow holds 11 patent records, tied for first, with its portfolio concentrated in C08J 7 (polymer processing and solutions), B32B 27 (layered laminates), and C09D 127 (fluoropolymer coatings). Its co-filing record with Rohm & Haas amplifies its effective IP footprint. No recent momentum signal is present in the applicant momentum data, consistent with the field’s decline-stage classification.
patent records: 11Oerlemans Packaging BV
Oerlemans Packaging BV holds 7 patent records, ranking third, and distinguishes itself from the chemical leaders by emphasizing B32B 27 (layered laminates), B65D 65 (packaging containers), and B32B 7 (laminate bonding structures) — a downstream, application-oriented profile. This positions the company closer to the packaging OEM segment rather than the polymer chemistry layer.
patent records: 7Frequently asked questions
The current corpus contains 9 patent families in scope. This is a narrow field, and the total reflects a technology area that has not attracted broad multi-applicant participation.
Dow Global Technologies LLC and Rohm & Haas Co are co-leaders, each with 11 patent records. Oerlemans Packaging BV ranks third with 7 patent records. These three applicants account for the large majority of activity among the top filers.
The field is classified as Decline. Annual filing volume peaked in 2021 at 5 records and has since eased sharply. The multi-year recent growth rate is negative. The 2024–2026 window may be under-represented due to publication lag, but the structural trend points to a maturing IP estate.
Europe (EPO) leads with 5 patent records, followed by China with 3. Austria, India, Mexico, the Netherlands, and the United States each have 2 records. Germany, Spain, and WIPO (PCT) each carry 1 record.
B32B (layered products and laminates) is the leading branch, followed by C08J (polymer processing and solutions) and C09D (coatings, paints and inks). B29D (specific plastic articles) is the sparsest branch with only 1 patent record.
The most significant co-filing relationship is between Dow Global Technologies and Rohm & Haas Co (US), with 9 joint filings — deepening their combined IP position beyond what either entity’s individual count indicates. A secondary relationship between Dow Global Technologies and Rohm & Haas Electronic Materials accounts for 2 joint filings.
