Australian Bin Liner & Garbage Bag Sizes Explained
Bin liner sizes in Australia are measured in litres, matching the volume of the bin they’re built for. Small 27 and 36 litre liners suit kitchen and bathroom bins, 54 litre kitchen tidy bags handle general household waste, and 72 to 85 litre liners cover larger internal bins. Wheelie bins take 120 to 240 litre liners depending on council bin size, while 200 litre drum liners suit industrial drums. Matching litre capacity to your actual bin, rather than guessing dimensions, is the fastest way to stop liners tearing, overhanging or falling inside the bin. Guessing bin liner size by eye usually ends in liners that gape at the top, slip down inside the bin or split under weight. Matching litre capacity removes the guesswork. Pinpak’s bin liners and garbage bags cover the full litre range in one place, from small kitchen bags through to heavy duty wheelie bin and drum liners.
How Bin Liner Sizes Work in Australia
Bin liners are sized by the litre capacity of the bin they fit, not by bag dimensions alone. A 120 litre liner is built for a 120 litre wheelie bin, even though the flat bag measures roughly 460mm plus gussets by 1080mm. Gussets, the folded sides on many bin liners, let the bag expand to match round or square bins without splitting at the seams. Thicker gauge liners also matter here. Our guide on choosing the right packaging thickness explains how micron rating affects how much weight a liner can hold before it tears. Checking your bin’s stated litre capacity, usually printed on the lid or body, is the quickest way to find the right size without measuring the bag itself.Small Bin Liners, 27L and 36L for Kitchen and Bathroom Bins
27 litre bin liners measure 510mm by 590mm and suit small kitchen, bathroom or office bins. They’re sold 50 bags per roll, packed 1,000 per carton. 36 litre liners step up to 580mm by 660mm, a common size for slightly larger kitchen bins or under desk bins in commercial offices. Both sizes use a lighter gauge film, which keeps cost per bag low for high frequency, low weight waste like food scraps, tissues and general office rubbish.54L to 85L, Kitchen Tidy Through to Heavy Duty Bins
54 litre kitchen tidy liners, sized 630mm by 890mm, are the standard for freestanding kitchen bins in most Australian homes and cafes. 72 litre black LDPE liners measure 760mm by 900mm and suit larger internal bins in offices, retail stores and hospitality kitchens. 85 litre heavy duty liners use a thicker 40 micron film and gusseted construction, built for bins holding heavier or bulkier waste like packaging offcuts or garden clippings.120L to 240L, Wheelie Bins and Bulk Waste
120 litre liners fit standard council wheelie bins and use a 30 micron film with gussets, priced per carton of 250. 200 litre drum liners suit 44 gallon drums, available in black 100 micron for industrial waste or natural 50 micron where contents need to stay visible. Our article on recycling plastic packaging responsibly covers how to sort and dispose of these larger liners correctly once they’re full. 240 litre liners are built for the largest council and commercial wheelie bins, with a heavy duty 50 micron option for construction or industrial waste alongside a lighter 25 micron option for general bulk rubbish.Choosing the Right Gauge (Micron) for Your Bin Liner
Micron thickness determines how much weight and sharp edged waste a liner can hold before it tears. Thin liners around 25 to 30 micron suit light general waste. Mid range liners around 40 to 50 micron handle mixed household or commercial waste with the odd sharp or heavy item. Heavy duty liners at 50 to 100 micron are built for construction offcuts, glass, metal edges or genuinely heavy loads where a split bag creates real mess and cost.Frequently Asked Questions
What size bin liner do I need for a 120 litre wheelie bin?
A 120 litre bin liner is the correct match for a standard 120 litre council wheelie bin. Pinpak’s 120 litre liners measure 460mm plus gussets by 1080mm and use a 30 micron film, which is enough for general household waste without tearing under normal weight. If your bin regularly holds heavier items like garden waste or packaging offcuts, it’s worth stepping up to a thicker gauge liner or a 240 litre heavy duty option, even in a smaller bin, to reduce the risk of splitting.What is the difference between 27 litre and 36 litre bin liners?
The difference comes down to bin size rather than bag strength. A 27 litre liner measures 510mm by 590mm and suits smaller kitchen, bathroom or office bins, while a 36 litre liner measures 580mm by 660mm for slightly larger kitchen bins. Both are supplied at a similar light gauge, so the choice really comes down to which one fits your bin without excess bag hanging over the rim or, on the other end, pulling too tight and tearing at the top.How many litres is a standard Australian kitchen tidy bag?
Most freestanding kitchen tidy bins in Australia take a 54 litre liner, sized at 630mm by 890mm. This size balances enough capacity for a household’s daily food scraps and general waste with a bag that is still easy to tie off and carry to an outdoor bin. Cafes and small hospitality kitchens often use the same 54 litre size for under counter bins, since it matches typical bin dimensions used in commercial kitchen fitouts across Australia.What micron thickness should I choose for heavy duty rubbish?
For heavy duty waste like construction offcuts, garden clippings or anything with sharp edges, look for a liner rated 40 micron or higher. Pinpak’s 85 litre heavy duty liners use 40 micron film, while the 200 litre drum liner and 240 litre heavy duty wheelie bin liner go up to 50 and 100 micron for genuinely tough loads. Thinner liners under 30 micron are fine for everyday household or office waste but will usually split under sharp or heavy contents.Are drum liners the same as bin liners?
Drum liners serve the same purpose as bin liners, containing waste and protecting the container, but they’re sized for 44 gallon drums rather than council wheelie bins. Pinpak’s 200 litre drum liners measure 1000mm by 1500mm and come in black 100 micron for industrial waste that needs to stay contained and out of sight, or natural 50 micron for situations where checking the contents visually matters, such as recycling or inspection processes. Matching litre capacity and gauge to your bin is the simplest way to stop liners splitting, slipping or running out too fast.Browse Pinpak’s full range of bin liners and garbage bags to find your size, or call 1300 421 527 to talk through bulk pricing for your business.
