Compostable cellulose-based OTR/WVTR barrier packaging solution
W-Cycle proposes enhancing its patented SupraPulp omniphobic cellulose material with food-grade compostable additives to achieve oxygen and water vapor transmission rate (OTR/WVTR) barrier properties. This innovation targets sustainable food packaging applications, offering a fully compostable alternative to plastic barriers for tier 1 food companies and institutional food service markets.
Overview
W-Cycle is developing a next-generation compostable packaging material that combines its patented SupraPulp omniphobic cellulose base with food-grade, compostable additives possessing oxygen and water vapor transmission rate (OTR/WVTR) barrier characteristics. The goal is to create a fully compostable packaging solution that meets the barrier performance requirements of demanding food packaging applications while eliminating dependence on plastic or chemical coatings.
This innovation directly addresses the growing demand from food manufacturers, institutional caterers, airlines, retail chains, and restaurant services for sustainable packaging that can reliably contain hot, wet, greasy, or oxygen-sensitive foods. By integrating barrier functionality into a cellulose-based substrate, W-Cycle aims to expand the applicability of compostable packaging into product categories that have traditionally required plastic-based barrier films.
Technical specifications
Core technology foundation:
- Built on W-Cycle's existing patented SupraPulp platform, a non-coated, cellulose-based material that is naturally omniphobic—resistant to liquids, oils, and grease without chemical surface treatments
- Temperature stability ranging from -40°C to 200°C, with microwave and oven-safe properties
- Compatible with molded fiber manufacturing processes
Barrier enhancement approach:
- Incorporation of food-grade, compostable additives with inherent OTR/WVTR barrier properties
- Custom additive recipes developed in-house to optimize barrier performance while maintaining compostability
- Additives selected for their ability to bond with cellulose fibers, ensuring material integrity
Manufacturing and prototyping capabilities:
- In-house laboratory for material testing and additive screening
- Proprietary additive formulations tailored to specific customer requirements
- Prototype development cycle of 3–6 months, followed by initial customer facility testing
Technology readiness level
W-Cycle has six years of R&D experience in molded fibers and pulp materials, supported by established laboratory infrastructure and manufacturing capabilities for producing molded fiber sheet samples. The company is actively testing multiple additives suitable for molded fiber substrates and developing unique proprietary recipes.
The base SupraPulp material is commercially available and currently being supplied to tier 1 food companies with custom formulations. The OTR/WVTR barrier enhancement is at an advanced R&D stage, with ongoing material testing and additive optimization. Prototyping and customer-side validation cycles are expected to take 3–6 months, after which initial testing can proceed in customer facilities.
About W-CYCLE
W-Cycle is an Israeli food-tech company that develops and manufactures sustainable, compostable food packaging solutions. The company's core innovation is SupraPulp, a patented, non-coated, cellulose-based material designed to serve as a high-performance alternative to traditional plastic packaging. Unlike conventional compostable options, SupraPulp is omniphobic, meaning it is naturally resistant to liquids, oils, and grease without the use of chemical coatings. The material is engineered to be durable across a wide temperature range, remaining stable in both freezing conditions as low as -40°C and high-heat environments up to 200°C, while also being microwave and oven-safe.
These packaging solutions are primarily targeted at B2B markets, including food manufacturers, institutional caterers, airlines, retail, and restaurant services that require reliable, leak-proof containment for hot, wet, or greasy foods. By providing a commercially competitive and environmentally friendly substitute, W-Cycle aims to address the global accumulation of plastic waste in landfills and oceans. The company, which maintains operations in Kibbutz Gan Shmuel, Israel, supports clients through custom design, prototyping, and manufacturing services, helping businesses transition away from plastic-dependent packaging architectures to fully compostable, nature-based alternatives.
