Verified by accredited third-party international certification bodies.
Yes. Ecopro compostable bags are certified to the world’s leading composting standards by accredited third-party certification bodies.
Our products hold certifications including BPI Commercial (ASTM D6400, License #10528743), European Bioplastics Seedling (EN 13432), and TÜV AUSTRIA OK compost INDUSTRIAL and OK compost HOME. We can also provide Australasian Bioplastics Association (ABAP AS 4736 and AS 5810) compliance upon request.
Each certification validates that the material breaks down safely in defined composting environments without leaving persistent microplastics or harmful residues.
Ecopro bags are manufactured from a bio-based composite formulation of PBAT (polybutylene adipate terephthalate), PLA (polylactic acid), and plant-based cornstarch resin.
They contain zero traditional non-biodegradable polyethylenes (PE, PP, or PVC) and do not use oxo-degradable additives. The polymer structure is designed to be digested by naturally occurring microorganisms in composting systems.
Ecopro compostable bags have an optimal shelf life of 10 to 12 months from the date of manufacture.
Because certified compostable resins naturally respond to moisture and heat, we recommend storing rolls in a cool, dry place away from direct sunlight and ambient temperatures exceeding 35°C (95°F). For commercial inventory, keeping cases sealed in original cartons ensures peak tensile strength and seal integrity.
No. Certified compostable bags undergo rigorous testing under ASTM D6400, EN 13432, and ISO 17088 standards.
Unlike conventional plastics that fragment into persistent microplastic particles, Ecopro materials are completely consumed by microbes in industrial or home composting facilities, converting into water, carbon dioxide (CO₂), and nutrient-rich biomass (humus) with verified ecotoxicity and heavy metal thresholds.
A reinforced star seal (X-seal) folds the bag material multiple times at the base before heat sealing, eliminating side seams and distributing the weight of waste evenly across the center of the bottom.
This design virtually eliminates bottom blowouts and wet leaks, making it the industry standard for organic food waste bins, municipal collection pails, and wet kitchen food scraps.
Under controlled industrial composting conditions (temperatures between 55°C and 60°C with adequate moisture and airflow), Ecopro liners disintegrate within 12 weeks and biodegrade within 180 days in accordance with ASTM D6400 and EN 13432.
For home compostable formulations (certified OK compost HOME and AS 5810), bags decompose under ambient garden composting temperatures over a slightly longer timeframe, matching the natural breakdown cycle of organic yard and food waste.
Yes. We engineer heavy-duty liners by adjusting film gauge (thickness from 0.015 mm to 0.05 mm / 0.6 mil to 2.0 mil), optimizing the PBAT/PLA polymer ratio, and applying heavy-duty star sealing.
Our engineering team confirms puncture risk, moisture content, and weight loads with buyers during sampling, locking in approved mechanical specifications before volume production.
Yes. Ecopro provides full OEM and private label manufacturing for retail brands, municipal programs, and wholesale distributors.
Customizable options include bag size (8L to 240L / 3 Gallon to 55 Gallon), film thickness, custom roll counts, coreless or cored rolls, custom Pantone film colors, up to 8-color flexographic printing, and retail packaging (printed paper boxes, shelf-ready display cartons, or branded outer bags).
Ecopro provides complete third-party compliance documentation matched to your exact ordered SKU.
This includes official BPI, TÜV AUSTRIA, or Seedling certificate copies, Technical Data Sheets (TDS), Material Safety Data Sheets (MSDS), material composition disclosures, and third-party laboratory test reports. We also supply logo usage authorization so your private label packaging complies fully with local green labeling laws.
We enforce multi-stage quality controls across our 60+ automated production lines. Extrusion lines are equipped with continuous thickness monitoring, while bag-making units check heat-seal temperature, perforation pitch, and dimension tolerances.
Finished lots are tested under AQL standards for tensile strength, elongation, dart drop impact, and leak resistance, with batch records and retained samples archived for complete traceability.
Our standard MOQ for custom star seal liners or private-label production is 1,000 kg per size/specification.
For evaluation and testing, we can provide in-stock sample rolls within 3 to 5 business days. Custom printed or custom-dimension prototype samples typically take 10 to 14 business days after artwork and technical specification sign-off.
We offer versatile packaging options tailored to your sales channels: coreless rolls with easy-tear perforated seams, paper sleeve bands, retail color boxes with dispensing slots, shelf-ready display cartons (PDQ), bulk master shipping cartons, and palletized shipments with stretch wrap protection.
