ELONGATION: > 120%HAZE INDEX: 2.1%

Synthesized via the fermentation of renewable plant starches like corn and cassava. In our multi-layer configurations, it functions flawlessly as an eco-friendly inner heat-sealing layer or a pure, clean single-layer carrier. It delivers superb low-temperature thermal sealability, crisp optical clarity, and robust grease-resistance—degrading smoothly back into natural compost without leaving microplastics or toxic chemical legacies behind.

Cellulose Core Layer (NK)Micro Vapor-Metallized Barrier (NKME)O₂ DeflectedH₂O Shielded
MVTR: < 0.5 g/m²/dayOTR: < 0.5 cc/m²/day

Engineered from sustainably managed wood pulp fibers (such as the premium NatureFlex series). Standard NK serves as a crystal-clear, high-tensile barrier layer, while NKME features a microscopic vapor-metallized layer that elevates its oxygen and moisture isolation to pure foil-like capabilities. This is the holy grail of sustainable engineering, providing the supreme barrier defense needed for hyper-perishable organics.

Sourcing FAQ

Sustainable Packaging FAQ: Demystifying Bio-Based Polymers

Rigorous batch testing and independent global laboratory validations guarantee absolute regulatory safety and mechanical line runability.

Absolutely not. PLA (Polylactic Acid) and NK/NKME cellulose films require a highly specific symbiotic ecosystem to trigger biodegradation—including constant elevated ambient temperatures (≥58℃), high relative humidity (≥90%), and active microbial presence. On dry, temperature-controlled warehouse shelves, these materials behave with identical molecular stability to traditional petrochemical films, exhibiting a secure storage life of up to 24 months without any degradation in structural tensile strength or gas barrier performance.
Industrial compostable packaging (certified under ASTM D6400 and EN 13432) requires municipal facility processing, where temperature, aeration, and bacterial colonies are artificially accelerated to break down robust structures like thick PLA linings within 180 days. Home compostable certification (like OK Compost Home) guarantees that lighter polymer matrices—such as our NK cellulose layers—possess a low enough molecular thickness and density to naturally melt and fully degrade back into ordinary backyard soil composting bins under ambient garden temperatures (20℃ to 30℃) within 26 weeks.
Standard bio-plastics have lower crystalline melting points, making them prone to burning under the rigid heat-sealing jaws of high-speed Form-Fill-Seal (FFS) automated machinery. We solve this by precisely regulating the co-polymer matrix. By cross-linking our stretched, high-tensile NK outer printable shell with custom thermo-stabilized PLA heat-seal layers, we broaden the thermal sealing window. This permits rapid, hermetic thermal fusion at optimal line speeds without causing film warping, web-curling, or layer delamination during automated commercial filling cycles.
