Compostable Bin Liners

Product Overview

AISUNBIO's compostable bin liners, also widely referred to as biodegradable plastic bags or biodegradable bags, are purpose-built for domestic food waste collection and municipal organic collection schemes. Designed to sit inside standard kitchen caddies, these liners hold food scraps securely until collection day, eliminating the need to empty caddies directly into collection bins and reducing mess during the waste sorting process. Manufactured with calibrated film thickness and reinforced structural design, the liners deliver reliable performance for both kitchen food waste and garden waste applications, aligning with the requirements of North American and UK municipal organics programs.

Core Product Features

1. Star-seal bottom design: The reinforced star-seal base distributes weight evenly across the bottom of the bag, eliminating weak corner seams that are prone to tearing or leaking. This structure holds its shape even under wet food waste, preventing messy leaks and bag rupture during storage and transport.
2. Dual certification compliance: The liners hold BPI Compostable certification for North American municipal organics programs, as well as EN 13432 certification, meeting the global safety and degradability standards for compostable waste bags.
3. Retail-ready packaging: Each pack comes in a printed dispenser box, which can be customized to display your brand logo, EAN barcode, BPI certification mark, and clear usage instructions, making it ready for direct retail shelf placement.
4. Wide caddy compatibility: The liners are sized to fit standard 6L and 10L kitchen caddies commonly used in UK and US households, with additional capacity options available for larger waste collection needs.
5. Full industrial compostability: The liners break down completely alongside food waste in industrial composting facilities, with no additional sorting required, reducing the workload for waste management teams and eliminating plastic contamination in compost output.
6. Flexible closure options: Customers can choose liners with or without tie-flap closure, adapting to different usage preferences and waste collection requirements.
7. Custom printing support: Custom box and bag printing is available for orders starting from 30,000 pieces, allowing brands to create tailored packaging solutions for their target markets.

3. No-sort composting convenience: Unlike traditional plastic waste bags that require manual sorting before composting, these compostable liners can be added directly to industrial compost piles along with their contents, streamlining the waste management process for households and municipal teams alike.
4. Retail-ready shelf appeal: The pre-printed dispenser box is designed for retail display, with clear branding, certification marks, and usage instructions that help consumers make informed purchasing decisions, reducing return rates and improving customer satisfaction.

Target Customers

This product is ideal for a wide range of customers, including retail consumer goods brands looking to expand their sustainable product lines, municipal waste management authorities seeking compliant waste bags for their organic collection schemes, grocery store chains offering household waste solutions, commercial food service providers needing reliable food waste collection bags, and sustainable packaging distributors serving the North American and European markets. Additionally, brands focused on zero-waste and eco-friendly household products can leverage the certified compostable liners to meet the growing consumer demand for sustainable waste management solutions.

Application Scenarios

The compostable bin liners are designed for a variety of waste collection scenarios, starting with household kitchen food waste collection, where they fit inside standard 6L and 10L kitchen caddies to hold fruit and vegetable scraps, coffee grounds, tea bags, and other food waste until curbside collection day. They are also suitable for garden waste collection, holding grass clippings, leaves, and small plant trimmings for municipal green waste programs. For municipal organic collection schemes, the liners are accepted directly into curbside organics bins, eliminating the need for residents to empty caddy contents manually. The larger capacity options (30L and 120L) are suitable for commercial food waste collection in restaurants, cafes, office buildings, and community events, providing a reliable, leak-proof solution for large volumes of organic waste. All liners can be added directly to industrial composting facilities, where they break down alongside organic waste to produce nutrient-rich compost, with no residual plastic contamination.

Industry Pain Points Solved

1. Solves the problem of non-compliant waste bags being rejected by municipal organics programs: With BPI and EN 13432 certifications, the liners meet the strict requirements of North American and European municipal composting programs, reducing the risk of entire waste batches being rejected due to non-compostable bag materials.
2. Eliminates messy leaks and bag rupture: The star-seal bottom design addresses the common issue of weak corner seams tearing under wet food waste, reducing mess during storage, transport, and collection.
3. Reduces waste sorting workload: Unlike traditional plastic bags that require manual sorting before composting, these liners can be composted directly with their contents, cutting down on labor costs for waste management facilities and reducing the risk of plastic contamination in compost output.
4. Improves retail shelf readiness: The pre-printed dispenser box eliminates the need for brands to source separate packaging, reducing time-to-market for new sustainable product lines and ensuring consistent branding and certification display for consumers.
5. Adapts to diverse customer needs: With multiple capacity, material, color, and closure options, as well as custom printing support, the liners can be tailored to meet the specific needs of different customer segments, from retail consumers to municipal authorities to commercial food service providers.
