Cellulose film — sometimes called regenerated cellulose film or by the historical brand name “cellophane” — predates modern petroleum-based plastics by decades. Invented by Swiss chemist Jacques Brandenberger in 1908 and commercialized through the 1920s-1950s, cellulose film was the dominant transparent packaging material before petroleum-derived alternatives (PET, polyethylene films, polypropylene films) displaced it through the 1960s-1990s. The material has returned to the compostable packaging landscape through the 2010s-2020s as one of the few genuinely transparent materials that biodegrades cleanly.

This guide is the working B2B reference on cellulose films from a foodservice perspective.
What Cellulose Film Actually Is
Cellulose film is regenerated cellulose — the same molecular structure as cellulose in plant cell walls (wood, cotton, hemp, bamboo) but processed into thin film form. The manufacturing process involves dissolving cellulose from plant feedstock, treating it chemically, and regenerating it as thin film through controlled processes.
Key properties:
Plant-based throughout. Made from wood pulp or other cellulose-rich plant materials. Bio-based at the molecular level.
Optically transparent. Cellulose film is naturally clear, providing visibility through the package.
Biodegradable. Cellulose biodegrades through normal environmental processes — the molecule is recognized by environmental microbes as the same material plants produce naturally.
Heat-sensitive. Pure cellulose film softens with heat; modifications or coatings extend the temperature range.
Moisture-sensitive without coatings. Pure cellulose film absorbs moisture; coatings (PLA-based, wax-based) provide moisture barrier where needed.
The History: Why Cellulose Film Came and Went
Cellulose film dominated transparent packaging through the mid-20th century:
1920s-1950s: “Cellophane” became synonymous with transparent food packaging. Wrapped candies, baked goods, and various retail products used cellophane wrapping universally.
1960s-1980s: Petroleum-derived plastics (polyethylene, polypropylene films, PET) became commercially competitive. Lower cost and improved moisture barrier properties displaced cellulose film across most applications.
1990s-2000s: Cellulose film essentially disappeared from mainstream foodservice. Petroleum film alternatives dominated.
2010s-2020s: Compostable packaging demand brought cellulose film back to commercial relevance. Modern producers (NatureFlex, others) provide compostable cellulose film alternatives to petroleum film equivalents.
The historical trajectory illustrates how material category dominance can shift based on cost and performance — and how regulatory and customer demand for compostable alternatives can revive previously-displaced materials.
Modern Cellulose Film Applications
In the contemporary compostable packaging landscape, cellulose film serves specific applications:
Compostable Cellophane Bags
For specialty produce (microgreens, herbs, flowers), bakery items (cookies, single-pastry presentations), and gift packaging where transparency drives sales.
The full compostable bags range includes cellulose-based cellophane bag formats.
Window Packaging Components
Some compostable food containers use cellulose film for window panels — providing visibility into the contents while the rest of the package uses fiber substrate.
Specialty Wrapping Applications
For premium gift packaging, specialty retail bakery wrapping, and similar applications where compostable transparency justifies the cost premium.
Limited Industrial Applications
Some specialty industrial applications continue using cellulose film for specific properties (dimensional stability, heat resistance in specific ranges).
Cellulose Film Compared to PLA Films
Both cellulose film and PLA film provide compostable transparency, but with different properties:
Cellulose film:
– Plant-based throughout
– Naturally compostable across multiple environments
– Higher cost typically
– Limited heat tolerance
– Sensitive to moisture without coatings
PLA film:
– Plant-based bioplastic
– Industrially compostable
– Lower cost typically
– Heat tolerance varies (PLA softens at 40°C)
– Better moisture barrier
For B2B procurement, the choice depends on application:
Cellulose film preferred: Specialty applications, gift packaging, where the historical aesthetic and broader biodegradability matter.
PLA film preferred: Volume cold packaging applications where cost matters more.
The full compostable food containers range covers various transparent packaging options across substrate alternatives.
Cellulose Film Cost Position
Cellulose film typically costs more than PLA film for equivalent transparent packaging:
- Cellulose film bags: $0.05-$0.12 per bag at pallet pricing (compared to PLA-based equivalents at $0.04-$0.10)
- Cellulose film window components: small premium over PLA window alternatives
For most B2B procurement, the cost premium is modest in absolute terms but meaningful at high volume. Specialty applications justify the cellulose preference; volume applications often default to PLA alternatives.
Compliance Considerations
For cellulose film procurement:
California SB 54 alignment. Compostable cellulose films satisfy SB 54’s compostability pathway when properly certified.
Certification verification. BPI certification or equivalent for the specific cellulose film SKU.
Some cellulose films are home-compostable. Pure uncoated cellulose film may qualify for TÜV OK Compost HOME certification — meaningful differentiation for some applications.
What “Done” Looks Like for Cellulose-Film-Aware Procurement
A B2B operator with cellulose film awareness:
- Understanding cellulose film as specialty compostable transparent material
- Application-appropriate use of cellulose film for premium positioning or specialty packaging
- Continued use of PLA film for cost-conscious volume transparent packaging
- Per-SKU certification verification for cellulose film SKUs
The compostable transparent packaging landscape includes both modern PLA bioplastic films and historical cellulose films now returning to commercial relevance. Understanding the material history and current positioning helps B2B procurement teams make informed choices when transparent compostable packaging is needed.
For most B2B foodservice procurement, the established categories across compostable cups and straws, compostable bags, and compostable food containers handle volume requirements; cellulose film fills specific specialty roles where the material’s distinctive properties justify the procurement choice.
Background on the underlying standards: ASTM D6400 defines the U.S. industrial-compost performance bar, EN 13432 harmonises the EU equivalent, and the FTC Green Guides govern how “compostable” can be marketed on packaging in the United States.
