We have developed a film that modifies polylactic acid using our unique technology, imparting flexibility and heat resistance while maintaining a high biomass content (95%) and biodegradability!

【Various Physical Properties (Film Thickness 50μm)】 〇Transparency ・Haze: Modified PLA 3.0% / General PLA 2.0–32.0% 〇Tensile Properties ・Tensile Strength: Modified PLA 19MPa / General PLA 35MPa ・Elongation: Modified PLA 72% / General PLA 4% 〇Dimensional Change Rate (Heat Resistance) ・MD: Modified PLA 100℃ 0.3%, 120℃ 0.3%, 140℃ 0.3% / General PLA not measurable due to shrinkage ・TD: Modified PLA 100℃ 0.8%, 120℃ 0.8%, 140℃ 1.5% / General PLA not measurable due to shrinkage

A film that releases highly volatile natural and artificial fragrances! It imparts the aromatic effects and insect-repelling properties of natural fragrances to the film!

【Examples of Repellent Performance】 〇 Fruit Fly Repellent Test Results ・Lavender Film: Repellent Rate 74% ・Copaiba Film: Repellent Rate 75% 〇 Cockroach Repellent Test Results ・Copaiba Film: Repellent Rate 93%

Industry-leading functional anti-fouling film! Used in marine environments, it prevents contamination from marine organisms simply by being applied.

〇Composition: Marine organism anti-adhesion film / Adhesive / Release film 〇General adhesive type (repositionable type): Suitable for marine equipment, floats, fishing materials, aquaculture materials, etc. Ideal when you do not want to use paint or damage marine equipment. The film can be removed after use, restoring it to its original state. 〇Strong adhesive type: For long-term use where detachment would be problematic, such as marine structures and ship bottoms. *For details, please download the PDF or contact us directly.*
