Garbage Bag Sizes: How to Choose the Right Bin Liner for Your Needs

Using the wrong size garbage bag can lead to leaks, spills, and wasted time. The right fit? It makes waste management clean, fast, and frustration-free.

At Matthews Cleaning Company, we supply a full range of commercial bin liners to suit everything from kitchen caddies to 240 L wheelie bins. In this guide, we’ll help you match garbage bag sizes to your bin type so your staff, site or household stays clean and compliant.

Why Garbage Bag Size Matters

Too small, and the liner slips down or tears. Too big, and you waste material and risk messy overhangs. Choosing the correct bin liner size:

• Improves hygiene and odour control
• Speeds up changeovers
• Reduces plastic waste and costs
• Prevents leakage and overfilling

Quick Reference: Garbage Bag Size Chart

Bin Size	Recommended Bag Size	Product Example
10–15 L (Bathroom / Caddy)	450 × 520 mm	Use 18 µm liners or compostable options
36 L (Under-sink / Office Bin)	500 × 600 mm	Classic 36 L Black Bin Liners
54 L (Kitchen / Café Bin)	600 × 740 mm	Classic 54 L Bin Liners
72–80 L (General Waste)	720 × 910 mm	Classic 80 L Bin Liners
120 L (Wheelie Bins / Janitorial)	900 × 1150 mm	Classic 120 L Black Bin Liners
240 L (Council Wheelie Bin)	1120 × 1470 mm	Classic 240 L Bin Liners

How to Measure for Bin Liners

To find the perfect garbage bag size, use this formula:

• Width: Half of the bin’s perimeter (Width × 2) + 100 mm for overhang
• Length: Height of the bin + half the diameter of the bin base

Or, skip the maths—just measure the bin and match it to our product chart above or contact our team for quick help.

Choosing the Right Thickness (Microns)

Garbage bag thickness affects puncture resistance:

• 18–20 µm: Ideal for light office waste, tissues, paper
• 25–30 µm: Suitable for kitchen, café and food scraps
• 30+ µm: Required for sharp, heavy, or industrial waste

All our Classic and Enviroplus bin liners are tested for commercial-grade durability, so you can bag waste with confidence.

Eco-Friendly Bin Liner Options

Looking to reduce plastic waste? We stock Enviroplus 80 L Compostable Bin Liners certified to Australian standard AS 4736 for commercial composting. These are ideal for food-service, schools, or venues working toward zero-waste goals.

How to Store Bin Liners Correctly

To extend shelf life and prevent breakdown:

• Store in a cool, dry cupboard away from direct sunlight
• Avoid storing near heat sources or cleaning chemicals
• Use FIFO (First In, First Out) rotation for large stock

Bin Liner Materials: HDPE vs LDPE

The two most common materials for bin liners in commercial environments are HDPE (High-Density Polyethylene) and LDPE (Low-Density Polyethylene). HDPE liners are thinner, rustling, and better suited to dry, light waste. LDPE liners are softer, quieter, and more puncture-resistant — better for heavy, wet, or sharp waste. For commercial kitchen use or heavy construction waste, always choose LDPE or a star-sealed bottom construction which distributes weight evenly and resists tearing at the base.

Bin Liner Thickness Guide

Bin liner thickness is measured in microns (μm). As a general guide for commercial use: 15–20 microns for light office paper waste, 25–30 microns for general purpose commercial waste, 40–50 microns for kitchen food waste and heavy general waste, and 60–80+ microns for construction, industrial, or sharps waste. Over-specifying liner thickness wastes money; under-specifying leads to split bags and double-handling. Match the thickness to your actual waste type and weight.

Choosing the Right Bin for Each Area

Different areas of a commercial facility have different bin requirements. Reception and office areas typically use 20–40L slim-profile bins with lids for a professional appearance. Kitchens and food preparation areas require 60–120L bins with foot pedals to maintain hygiene (no hand contact). Outdoor collection points use 240L wheelie bins with lockable lids. Recycling stations benefit from clearly labelled, colour-coded multi-stream bins. Our commercial bins range covers all of these applications.

Recycling and Waste Segregation

With increasing regulatory and corporate responsibility requirements around waste segregation, commercial facilities are increasingly deploying multi-stream waste systems. A typical commercial waste segregation system includes: general waste (red or black lid), commingled recyclables (yellow lid), paper and cardboard (blue lid), organic waste/food (green or brown lid), and clinical or hazardous waste (purple or orange containers in healthcare settings). Clear labelling and signage are essential to ensure staff and visitors use bins correctly. Matthews Cleaning stocks compliant waste management solutions for all facility types.

Bin Liner Cost Management for Large Facilities

For facilities consuming high volumes of bin liners — hotels, hospitals, shopping centres, aged care facilities — purchasing in bulk carton quantities significantly reduces per-unit cost. Buying the correct size and thickness (rather than oversizing as a safety margin) also reduces waste expenditure.
