Compostable Bin Liners

Product Overview

Compostable bin liners are designed as a sustainable replacement for conventional polyethylene plastic trash bags, tailored to fit the most common tall kitchen bin size used across North America. The product line also includes 3-gallon kitchen waste bags, built with the same 100% compostable material and star-sealed bottom for extra strength, ideal for small countertop food scrap bins. These liners are also commonly known as biodegradable plastic bags or biodegradable bags, as they are formulated to fully decompose in industrial compost processing environments, replacing conventional polyethylene trash bags that persist in landfills for hundreds of years. The 13-gallon (49L) capacity liner is built to support full-week food scrap collection for typical households, eliminating the need for frequent bag changes between kerbside compost collection days. Manufactured with a PBAT + PLA blend material, the liner delivers reliable performance for wet food waste loads, with a star-sealed bottom structure that prevents base failure even under heavy, full-capacity loads. The product holds triple global compostability certifications, making it suitable for both retail consumer sales and institutional bulk procurement, and can be labelled with custom brand and sustainability messaging to align with partner brand values.

Core Product Features

1. 100% compostable material: Made from a PBAT + PLA blend, the liner breaks down fully in industrial compost environments, replacing conventional non-biodegradable polyethylene trash bags to reduce household plastic waste.
2. Versatile size options: The product line includes both 3-gallon small kitchen waste bags and 13-gallon tall kitchen bags, with the 13-gallon dimensions calibrated to fit standard 13-gallon (49L) waste bins used in most US and Canadian households, eliminating loose bag fit issues that can cause liner slippage or messy overhang.
3. Heavy duty thickness for wet loads: With an 18–25 μm film gauge, the liner is thick enough to hold a full week of typical family food waste, including wet scraps like fruit peels, vegetable trimmings, coffee grounds and food leftovers, without tearing or puncturing.
4. Star-seal bottom construction: The reinforced star-sealed base distributes weight evenly across the bottom of the bag, eliminating weak points that can cause leaks or base failure when carrying heavy wet loads, a common pain point with thin, flat-seal trash bags.
5. Triple global certification: The liner is certified by BPI, EN 13432, and ASTM D6400, meeting the strictest global standards for industrial compostability, so users do not need to worry about the bag being rejected at compost processing facilities.
6. Wide municipal acceptance: The liner is accepted by municipal compost facilities in over 30 US states, making it a reliable choice for households participating in curbside compost collection programs across most of the country.
7. Custom brand labelling support: The liner can be printed with custom brand logos and sustainability messaging, allowing retail brands, institutional suppliers and bulk purchasers to align the product with their own sustainability commitments and brand identity.

Core Advantages for Buyers

For retail buyers, the 13-gallon compostable liner format is the most in-demand size for household sustainable waste products, as it matches the bin size most North American consumers already own. The triple certification removes consumer uncertainty about compost facility acceptance, reducing return rates and customer support inquiries related to compostability compliance. The heavy duty 18-25μm thickness eliminates common customer complaints about thin compostable bags tearing under wet food loads, improving product satisfaction and repeat purchase rates. The standing display box pack format is optimized for retail shelf visibility, making it easy for shoppers to identify and select the product without additional packaging modifications.
For institutional buyers, including office buildings, restaurants, schools and municipal waste programs, the liner’s wide acceptance across 30+ US states simplifies procurement, as it can be used across multiple service regions without needing to source different bag types for different compost facility requirements. The durable star-seal construction reduces operational costs associated with bag leaks, which can require additional cleaning of waste stations and common areas. The option to source 3-gallon small liners also allows institutional buyers to stock bags for small countertop scrap bins in break rooms and kitchen areas, creating a consistent waste collection system across all facility sizes.
For brand partners, the custom labelling option allows brands to highlight their sustainability commitments directly on the product, resonating with eco-conscious consumers who prioritize brands that take tangible action to reduce plastic waste. The product’s alignment with circular economy goals makes it a strong addition to any sustainable product line, helping buyers meet their own plastic reduction targets and communicate their environmental values to customers.

Application Scenarios

This compostable bin liner is designed for a wide range of food scrap collection scenarios. For household use, the 13-gallon tall liner fits standard kitchen countertop tall bins, allowing families to collect food waste over a full week without frequent bag changes, before transferring the full liner to the curbside compost bin on collection day. The 3-gallon small liner is ideal for compact countertop scrap bins placed directly next to kitchen prep areas, making it easier for households to separate food waste from general trash without needing to walk to a larger bin. For commercial use, the liners are suitable for restaurant kitchen food waste collection, office break room waste bins, school cafeteria scrap collection, and multi-family residential building compost programs. They are also ideal for retail sale to eco-conscious consumers looking to replace conventional plastic trash bags with a more sustainable option for their kitchen waste. Unlike thinner, lower-gauge compostable bags, these liners can hold wet, heavy food loads without leaking, making them suitable for even high-volume food waste generation scenarios.

Industry Pain Points Solved

The product addresses several long-standing pain points in the compostable bag market. First, it solves the common problem of size mismatch: many compostable bags on the market are too small or too large for standard 13-gallon North American kitchen bins, leading to loose fit, slippage, or bags that are too tall to fit under bin lids. The calibrated dimensions of the 13-gallon liner ensure a snug, secure fit for most standard tall kitchen bins, while the 3-gallon option fills the gap for small countertop scrap bin needs.
Second, it solves the issue of poor durability: many low-cost compostable bags use thinner film gauges that tear easily when holding wet food waste, leading to messy leaks and customer frustration. The 18-25μm heavy duty film, combined with the reinforced star-seal bottom, ensures the bag can hold a full week of family food waste without tearing or base failure.
Third, it solves the compliance uncertainty problem: many compostable bags lack recognized certifications, leading to rejection at municipal compost facilities, which erodes consumer trust in compostable products. The triple BPI, EN 13432 and ASTM D6400 certification, combined with acceptance across 30+ US states’ compost facilities, gives consumers and buyers confidence that the bag will be accepted in standard compost processing streams.
Fourth, it solves the brand alignment gap: many generic compostable bags do not offer custom branding options, making it hard for retail brands and institutional buyers to showcase their own sustainability values. The custom labelling option allows partners to add their own brand messaging and sustainability claims directly to the bag, creating a more cohesive brand experience for end users.

Target Customer Groups

The product is designed for a diverse set of B2B buyers across the North American market. This includes retail consumer goods brands looking to expand their sustainable home product lines, grocery store private label programs, bulk wholesale distributors of sustainable waste products, commercial kitchen supply providers, municipal waste management departments running curbside compost programs, multi-family residential property managers, office space operators, restaurant chain supply procurement teams, and school and university facility management teams. All of these customer groups share a common need for reliable, certified, durable compostable bin liners that fit standard North American waste bins, and that are accepted by local compost processing facilities. The flexible size options, custom branding support, and global certifications make the product suitable for both small retail buyers and large institutional procurement teams.
