Active High-Barrier Film Patent Snapshot 2026
Active high-barrier film patenting is highly concentrated, with Cryovac Inc commanding the dominant position among the ranked filers. Filing activity is in a Growth stage, with recent-window momentum up 200% and several new entrants emerging in the most recent period.
Cryovac leads a sharply concentrated field
Cryovac Inc holds the top-ranked position, accounting for the largest share of patent records among the ranked applicants visible in this query. The top five applicants together account for 67% of the combined total of the ranked applicants visible in this query, signalling a field where a handful of incumbents set the pace.
The gap between Cryovac and the second-ranked applicant, Brueckner Maschinenbau GmbH & Co KG, is substantial. Below those two, remaining ranked applicants each hold only one or two patent records, indicating a long, fragmented tail with limited mid-tier competition.

Cryovac’s lead position implies deep freedom-to-operate constraints in multilayer laminate and coextrusion approaches. Entrants and challengers would need to differentiate on material chemistry, specific additive systems, or application-specific designs to carve out defensible space.
The most recent 18–24 months are likely under-counted due to standard patent publication lag; apparent low activity in 2025–2026 should not be interpreted as a slowdown. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Growth-stage momentum with layered-products technology dominant
The filing trend and technology composition charts together reveal a field expanding on a multi-year basis, anchored in multilayer laminate structures, with smaller but meaningful activity in plastics shaping and packaging applications.
Annual filing trend
Activity has grown over the observed window, with the recent three-year period delivering 200% growth versus the prior comparable period. Counts for 2025 and 2026 are understated by publication lag and should not be read as stagnation.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
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.
Cryovac Inc
Cryovac holds 14 patent records at the top of the ranking, with technical emphasis on B32B 27 (layered products and laminates), B29C 48 (shaping of plastics), and B65D 65 (containers and packaging). This broad, cross-functional coverage spans material structure through to end-use packaging, making it the deepest incumbent in the field. Momentum data does not flag a recent surge, consistent with a mature leadership position built over multiple filing cycles.
patent records: 14Brueckner Maschinenbau GmbH & Co KG
Brueckner holds 3 patent records with focus on B32B 27 (layered products and laminates), B29C 48, and B29C 55 (shaping of plastics — stretching), indicating a process-equipment orientation rather than material-composition coverage. This differentiated route means Brueckner’s patents are likely less directly blocking for material-science entrants, while posing constraints for equipment-integrated barrier film processing.
patent records: 3Frequently asked questions
The corpus covers 6 patent families in scope. The applicant ranking and technology classification are built from patent records, which can exceed the family count when a single family is filed across multiple offices.
Cryovac Inc is the top-ranked applicant with 14 patent records, far ahead of the second-ranked applicant, Brueckner Maschinenbau GmbH & Co KG, which holds 3 patent records.
The field is classified as Growth, with annual filings still rising and recent-window growth reaching 200% versus the prior comparable period. New entrants have appeared in the most recent filing cohort.
New Zealand leads with 8 patent records, followed by Europe (EPO) with 6 and the United States with 3. Germany, India, Japan, and WIPO (PCT) each carry 2 records, and China holds 1.
B32B (layered products and laminates) is the visible class with 27 patent records. Under-served adjacent branches include C08K (use of additives in polymers) with 3 records and A01G (horticulture and forestry) with 1 record.
One co-applicant relationship is documented: Jiangsu Jicui Advanced Polymer Material Research Institute Co., Ltd. and Nanjing Tailenwei New Material Technology Co., Ltd. filed one record jointly. The broader field otherwise operates through solo filings.
