Compostable Bin Liners

Product Overview

Compostable bin liners, also known as biodegradable plastic bags or biodegradable bags, are specialized waste collection solutions designed for kitchen food waste sorting and industrial composting processes. The 6L format of these caddy liners is widely recognized as the workhorse size for European kitchen composting scenarios, perfectly matching the daily food scrap collection needs of most households and small commercial kitchens. Manufactured by AISUNBIO, this 6L caddy liner adopts a deliberately heavier film gauge compared to most competing products on the market, with a thickness range of 15–22 μm, far exceeding the industry norm of 10–13 μm. This extra thickness directly addresses the most common pain point of existing compostable bin liners: tearing when removing a full, wet bag from the caddy. Combined with a four-point star-seal welding structure at the base, it completely eliminates base blow-out issues and handle-area tearing that often occur with ordinary thin compostable bags. The product holds both EN 13432 and BPI compostable certifications, covering compliance requirements for both EU and US markets, making it suitable for cross-border sales and global supply chain matching.

Core Product Features

1. Extra-thick film gauge: The 15–22 μm thick film is significantly more durable than the industry standard 10–13 μm thin film, effectively preventing punctures caused by sharp food scraps such as fruit peels, bone fragments, and hard vegetable stems.
2. Four-point star-seal bottom: The unique 4-point welded star seal structure eliminates weak corners that are prone to splitting under wet load, ensuring no leakage even when the bag is filled with high-moisture food waste such as wet coffee grounds, meat scraps, and citrus peels.
3. Flat-pack format: The product is packaged in flat-pack cardboard boxes, which is ideal for retail shelf display, saving valuable shelf space and making it easy for consumers to browse and pick up the product.
4. Full industrial compostability: The material can break down completely in industrial composting facilities alongside food waste, leaving no toxic residue or microplastic pollution, meeting the requirements of circular economy development.
5. Dual market certification: Both BPI and EN 13432 certifications are obtained, covering the compliance standards of the US and EU markets respectively, eliminating the compliance barriers for cross-border sales.
6. Private-label friendly: The product is suitable for private-label supermarket own-brand programs, supporting retailers to build their own exclusive waste solution product lines.

Application Scenarios

This 6L compostable bin liner is specially designed for kitchen food waste caddies, and is suitable for a wide range of scenarios. First, it is ideal for household kitchen food waste sorting, matching the 3–5 day food scrap collection cycle of most families, making it a perfect fit for daily household waste sorting needs. Second, it can be used in small commercial kitchens such as cafes, bakeries, and small restaurants, to collect food waste such as coffee grounds, fruit peels, and food scraps, ensuring no leakage during waste collection and transfer. Third, it is suitable for retail shelf display in supermarkets, convenience stores, and eco-friendly product stores, as the flat-pack format is easy to display and the dual certification can enhance consumer trust in the product's environmental performance. Fourth, it can be used as a supporting product for municipal waste sorting programs, helping residents to sort food waste conveniently and promoting the smooth implementation of municipal waste classification policies. In addition, it is suitable for private-label own-brand programs of supermarket chains, helping retailers to build their own eco-friendly product lines and meet the growing consumer demand for sustainable waste solutions.

Target Customers

The target customers of this compostable bin liner include multiple groups: First, supermarket chains and large retail groups that need to develop private-label own-brand eco-friendly products, as the product supports custom packaging and has sufficient production capacity to meet large order demands. Second, cross-border e-commerce sellers and distributors of eco-friendly household products, who need products with US and EU dual certifications to sell in the North American and European markets. Third, municipal environmental protection departments and waste sorting program operators, who need to provide supporting waste collection bags for residents to promote food waste sorting. Fourth, small and medium-sized catering enterprises such as cafes, bakeries, and small restaurants, who need durable and leak-proof food waste collection bags to improve the efficiency of kitchen waste management. Fifth, eco-friendly product stores and offline retail stores that focus on selling sustainable household products, who need high-quality compostable waste bags to enrich their product portfolio and meet the demand of environmentally conscious consumers.

Industry Pain Points Solved

The product is developed to solve multiple common pain points in the current compostable bin liner market. First, it solves the problem of easy puncture and tearing of ordinary thin compostable bags: most competing products use 10–13 μm thin film, which is easy to be punctured by sharp food scraps such as citrus peels, bone fragments, and hard vegetable stems, leading to leakage of food waste. The 15–22 μm extra-thick film of this product greatly improves the puncture resistance, eliminating this problem. Second, it solves the problem of base blow-out and corner splitting: ordinary compostable bags often use a simple flat seal bottom, which has weak corners that are prone to splitting under wet load, leading to leakage when the bag is full. The four-point star-seal bottom of this product evenly distributes the weight of the wet waste, completely eliminating base blow-out issues. Third, it solves the compliance barrier for cross-border sales: many compostable bags only have one certification, either BPI for the US or EN 13432 for the EU, which requires sellers to prepare different products for different markets, increasing inventory costs. This product has both certifications, covering both markets, reducing the inventory and compliance costs for sellers. Fourth, it solves the poor display effect of ordinary compostable bags: many products are packaged in bulky rolls, which take up a lot of shelf space and are not convenient for consumers to pick up. The flat-pack format of this product is ideal for retail shelf display, improving shelf space utilization and consumer shopping experience. Fifth, it solves the problem of incomplete composting: some low-quality compostable bags cannot be fully degraded in industrial composting facilities, leaving microplastic residue, which violates environmental protection requirements. This product is certified to be fully compostable, ensuring no harmful residue after degradation, meeting the requirements of circular economy.
