Structural Polysaccharide Platform: The Scientific Foundation Behind Sacralin™

 
 What Is Structural Polysaccharide Technology?

Structural polysaccharides—such as alginate, agar, cellulose, chitosan, and starch—are naturally occurring polymers with inherent molecular strength, film-forming ability, and biodegradability. Unlike synthetic bioplastics (PLA, PHA, PBAT), which require chemical synthesis or fermentation, these polysaccharides are directly extracted from renewable biomass and can be engineered to mimic plastic-like behavior.

Sacralin™ is based on a proprietary blend of agar, sodium alginate, and glycerin, designed to perform as a drop-in thermoplastic replacement on existing plastic manufacturing equipment — without retooling.

 
Why Structural Polysaccharides Are Different (and Why They Matter)

Direct natural extraction
Biodegradation
30 days (soil, compost, or marine)
No microplastic residue
Runs on existing plastic equipment
Biodegrades naturally — safe for soil, water, marine
High regulatory interest
 
How Sacralin™ Works (Science Behind the Performance)

Sacralin's performance is rooted in molecular behavior and structural interactions of its three core ingredients:

·       Agar — Structural backbone

Forms a solid, glassy network when cooled, giving shape, rigidity, and thermoformability.

·       Sodium Alginate — Strength, bond stability, and water resilience

Cross-links in the presence of calcium or heat, improving moldability, flexibility, and tensile strength.

·       Glycerin — Plasticizer and mechanical tuner

Controls elasticity, flexibility, and processing performance—acting similarly to petroleum plasticizers (phthalates, adipates) but naturally derived.

 Sacralin’s material behavior mimics thermoplastic polymers.

 
Industrial Processing Compatibility (Drop-In)
