Compostable Bin Liners

Product Overview

Compostable bin liners, also commonly referred to as biodegradable plastic bags or biodegradable bags, are designed to replace traditional single-use plastic bin liners for food waste collection in kitchen caddies and outdoor composting systems. Our range of compostable bin liners includes 6L kitchen caddy liners as well as 10L and 20L variants, engineered to be 100% leak proof, strong, and exceptionally durable for daily household and commercial use. Unlike standard biodegradable bags that only break down in high-temperature industrial composting facilities, our liners are certified to biodegrade in home garden compost heaps at ambient temperatures, aligning with the growing global shift towards circular economy and zero-waste waste management practices. The product range is manufactured at our Shouguang factory, which maintains a full quality system to sustain the required compostability certifications, including incoming resin testing and annual third-party audits to ensure consistent product performance.

Core Certification Advantages

Our compostable bin liners hold dual TÜV Austria OK Compost certifications, the most rigorous and widely recognized compostability standards globally. The OK Compost HOME mark (certification number TA8022004873) is the most demanding compostability certification available, confirming that the bags fully biodegrade in a home garden compost pile at ambient temperatures, without requiring the high heat and controlled conditions of industrial composting facilities. The OK Compost INDUSTRIAL mark (certification number TA8012004872) further validates that the liners also break down efficiently in industrial composting environments, offering end-of-life flexibility for users with access to either home or industrial composting systems. The scope of these certifications includes both printed and coloured film variants, meaning custom printed liners for private label programs retain full compostability compliance. Additionally, the liners meet the requirements of Australian council schemes specifying AS 5810 equivalence, making them suitable for use in regions with mandatory compostable waste collection regulations. The product range also meets the strictest European retailer sustainability policies, positioning it as a compliant option for private label programs across major global supermarket chains including Woolworths, Coles, Aldi, Lidl and Tesco.

Quality Assurance System

Our Shouguang manufacturing facility maintains a comprehensive quality management system designed to uphold the strict requirements of TÜV Austria compostability certifications and global retailer sustainability standards. This system includes rigorous incoming resin testing to ensure all raw materials meet compostability specifications, eliminating the risk of non-compliant materials entering the production process. The facility also undergoes annual third-party audits to verify ongoing compliance with certification requirements, as well as regular internal quality checks to ensure consistent product performance across all production batches.

Industry Pain Points Addressed

Our compostable bin liners are engineered to solve key pain points in the sustainable waste management and compostable product market, including:
1. Limited Home Compostability: Many compostable bin liners on the market only break down in high-temperature industrial composting facilities, leaving households without access to industrial composting unable to compost their food waste. Our liners are certified to break down in home garden compost heaps at ambient temperatures, solving this accessibility gap for residential users.
2. Leaks and Durability Issues: Traditional thin compostable liners often tear or leak when holding wet food waste, creating mess during collection and disposal. Our 12-18 μm thick film and star seal bottom construction are 100% leak proof and exceptionally durable, eliminating these common user complaints.
3. Retail Compliance Gaps: Many compostable liners fail to meet the strict sustainability policies of leading supermarket chains, making them unsuitable for private label programs. Our liners hold dual TÜV Austria certifications and meet AS 5810 equivalence requirements, ensuring compliance with major retailer and municipal scheme standards.
4. Compromised Certification for Printed Products: Many compostable bag manufacturers lose their compostability certification when using printed or coloured film, as inks can interfere with biodegradation. Our TÜV Austria certifications cover both printed and coloured film variants, allowing for custom branded private label products without compromising compliance.
5. Caddy Compatibility Issues: Many compostable liners are not designed to fit standard EU and AU kitchen caddy dispensers, leading to difficult dispensing and user frustration. Our roll format is engineered to fit standard EU and AU caddy dispensers, ensuring a seamless user experience.
