Oriented PE Film Patents: Top Companies & Filing Trends 2026
- 57.6% of all 491 records sit with just five assignees, so freedom-to-operate work in this field starts with a short list, not a long one.
- Filings fell 55% from 40 in 2021 to 18 in 2024 — the only complete three-year comparison the data supports, after a 2022 peak of 63.
- B32B laminate claims cover 60.5% of records, while adhesive-layer claims under C09J sit at just 8.6%, a much thinner claim thicket.
Filing growth compares 2021 (40 records) with 2024 (18) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 491 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
Mono-material laminates replace mixed-polymer packaging structures with a single resin family so the pack can be recycled without separating layers. Oriented polyethylene film — stretched in the machine direction or biaxially to raise stiffness and improve the sealing window — is the enabling component, and the search behind this page pulls together records that discuss stretch ratio, stiffness increase, sealing window, film printability, optical haze and line conversion alongside oriented or machine-direction-oriented polyethylene film. The scope runs from 2015 through the 2026-07-31 data cut-off.
The 491 records in scope span resin producers, film converters and adhesive/label specialists rather than a single industry segment, which is why the IPC composition below spreads across polymer chemistry, film shaping and finished-laminate classes rather than clustering in one.
Filing trend and technology composition
Two views of the same 491 records: how filing activity has moved year over year, and which IPC subclasses carry the claims.
Filing activity has cooled from its 2022 peak
Filings rose from 24 in 2017 to a peak of 63 in 2022, then fell to 18 by 2024 — a 55% drop over the 2021-2024 span, the last window the data can call complete. Because publication lags filing by roughly 18 months, the 2025 and 2026 counts (partial, ending at 3) are still filling in and should not be read as a continued decline.
Laminate and polymer-processing classes dominate
B32B (layered products & laminates) touches 60.5% of the 491 records and C08J (polymer processing) 38.7%, reflecting that most filings claim either the finished laminate structure or the resin-to-film conversion step. C09J (adhesives, 8.6%) and B65D (containers & packaging, 8.4%) are comparatively thin, since a record can carry multiple classes these shares sum to more than 100%.
Shares are the percentage of the 491 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Citation counts accumulate over time, so older US filings from the microfiber and coextrusion literature lead the table; treat them as markers of influence on the field's foundational film science rather than as current state of the art.

Concentration, class spread and citation age each tell a different part of the story — read together they point to where claim space is occupied and where it isn't.
The top of the field is narrow
Five assignees account for 283 of the 491 records in scope, and the top ten extend that to 79.0%. A freedom-to-operate review for a new mono-material laminate film can reasonably prioritise this small group before widening the search.
Growth has receded from its 2022 peak
Filings peaked at 63 in 2022 and had fallen to 18 by 2024, a 55% decline over that span. The 2025-2026 counts are still incomplete because of publication lag, so this reading should stop at 2024 rather than extrapolate further.
Laminate structure claims dominate; adhesive claims are thin
B32B (layered products) appears in 60.5% of the 491 records while C09J (adhesives) appears in only 8.6%. That gap suggests adhesive-layer chemistry tuned for mono-material PE stacks is comparatively under-claimed relative to the laminate architecture itself.
Foundational citations skew older
The most-cited records in this set date to the 1990s-2000s microfiber and coextrusion literature. High citation counts here mark historical influence on film science, not which assignees are active in oriented PE laminates today.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to oriented polyethylene films for mono-material laminates, with the prior art for and against each one.
Who is filing, and where momentum has shifted
The ranked leaders are resin producers and film/label converters; recent-year activity has slowed across nearly all of them at once.
One resin producer sets the pace
The leading assignee holds 103 of the 491 records, well ahead of fifth place at 28 and tenth place at 16 — a steep drop-off that marks this as a leader-plus-long-tail field rather than an evenly split one.
Recent-year activity has gone quiet across the leaders
Several of the most active historical filers, including major resin producers, show zero filings in the latest year against a prior-year base, a -100% year-on-year reading. One assignee bucks this pattern with 3 filings in the latest year, +50% YoY, suggesting activity is consolidating rather than disappearing.
One producer pairing files together repeatedly
The strongest co-assignee pair in this dataset appears together 19 times, well ahead of the next pairings at 5 each. That level of repeat co-filing usually reflects a joint venture or shared production arrangement rather than incidental overlap.
| Assignee | Recent year | YoY |
|---|---|---|
| Basell Polyolefine GmbH | 3 | +50% |
| Dow Global Technologies LLC | 0 | -100% |
| Borealis AG | 0 | -100% |

One assignee leads with 103 of the 491 records in scope, well ahead of the fifth-ranked company at 28. The top five assignees combined hold 57.6% of all records, so a competitive review can start with a short list rather than the full 79-company ranking. That said, the long tail is real: most of the remaining companies appear with only a handful of filings each, which suggests active but fragmented interest outside the leaders.
Filings grew from 24 in 2017 to a peak of 63 in 2022, then declined to 18 by 2024, a 55% drop over that three-year span. The 2025 and 2026 counts look lower still, but publication typically lags filing by around 18 months, so those most recent years are undercounted rather than genuinely quiet. The safest read is that momentum has cooled from its 2022 high, not that the technology is being abandoned.
It is a TotalEnergies OneTech filing published in March 2025 for a biaxially-oriented polyethylene film built from a resin with specific melt index, density, and molecular-weight-distribution parameters, including a minimum Mz of 800,000 g/mol. The claims tie the film to that resin composition and to a production process, rather than to a generic 'oriented PE film' concept. Anyone formulating a high-density PE resin for biaxial orientation should check its exact numeric ranges before finalising a resin spec.
Adhesive and tie-layer chemistry for mono-material PE stacks looks comparatively open: C09J (adhesives) appears in only 8.6% of the 491 records against B32B's 60.5% for laminate structures generally. Print-surface treatment and low-haze high-speed biaxial orientation also show thinner coverage relative to the core laminate and resin-processing classes. These are reasonable areas to scope a first claim, though a full clearance search should confirm the gap before drafting.
The most-cited records here date back to the 1990s and 2000s and relate to microfiber and coextruded film science, with the top record cited 323 times. Older patents simply have had more time to accumulate citations within any searched corpus, so high citation counts mark historical influence on the field rather than which companies are active today. For a current-activity view, the filing-trend and assignee-ranking data are more reliable than the citation table.
