Aluminium Milk Can Sizes: A 5L to 50L Capacity Guide for Dairies

November 1, 2026

For most Indian dairies, the practical aluminium milk can sizes are 20 litre and 40 litre for collection and transport, 5–10 litre for small farms and home delivery, and 30–50 litre for collection centres and bulk movement. The right size balances how much milk you handle per round against what a person can safely lift when the can is full.

Milk can sizes and what each is used for

• 5 litre: single buffalo/cow households, doorstep delivery, sample and testing cans.
• 10 litre: small farms, hotels and halwais collecting their own milk.
• 20 litre: the workhorse for village collection and two-wheeler transport — full weight stays manageable.
• 30 litre: a middle size for busier routes and small collection points.
• 40 litre: the standard for collection centres, cooperatives and dairy transport by tempo or cart.
• 50 litre: high-volume collection and chilling-centre feed, usually moved on trolleys.

Remember: capacity is not the same as weight

Milk weighs roughly 1.03 kg per litre, so a 40 litre can holds about 41 kg of milk plus the can's own weight. This is exactly why aluminium is preferred over steel for cans that people lift all day — an aluminium can is far lighter than a stainless steel one of the same size, which cuts strain and spillage during loading. If your team lifts cans onto vehicles by hand, a 20 litre is kinder on the back than a brimming 40 litre.

How to choose the right size for your dairy

Work backwards from your route, not from the biggest can you can buy:

• Milk per collection point: match the can so it fills in one or two rounds — a half-empty can sloshes and dents.
• Who lifts it: if one person loads and unloads, stay at 20–30 litre.
• Transport: two-wheelers suit 20 litre; tempos and carts handle 40–50 litre.
• Cleaning: smaller mouths are harder to scrub — check the neck opening before you commit (see our guide on cleaning and sanitising a milk can).

Standard sizing and build

Aluminium milk cans in India are commonly made to IS 1825 dimensions, with a tapered or straight body, a fitted lid, and welded or spun seams for a leak-proof base. At UB Aluminiums we make food-grade aluminium milk cans from 5 to 50 litres, with reinforced rims and strong handles for daily collection. If you are deciding between materials first, read aluminium vs stainless steel milk cans.

FAQs

What is the most common milk can size in India?
The 40 litre aluminium milk can is the most widely used for collection centres and dairy transport, with 20 litre popular for village-level collection on two-wheelers.

How much does a full 40 litre milk can weigh?
About 41 kg of milk plus the can's own weight — one reason dairies prefer lightweight aluminium cans that are easier to lift and load than stainless steel.

What size milk can should a small dairy farmer buy?
A 10 or 20 litre can usually suits a single-household or small farm — large enough for a full collection, small enough for one person to carry and clean easily.
