Boba shops can sell their own canned milk tea with a countertop can sealer and empty clear 16 oz cans: build the drink cold, fill, seal, date the can, and keep it refrigerated. Milk tea holds its quality for about 3 to 5 days in the fridge. Pearls are the honest constraint, since tapioca firms up within hours refrigerated, so most shops sell pearl cans same day, add fresh pearls at pickup, or run jelly and popping toppings that hold. Pearls visible through a clear can are the best fridge marketing a tea shop gets.
Because boba already sells on sight. Pearls resting at the bottom, a brown sugar streak up the wall, milk clouding into tea: that is the whole reason customers film the drink before they sip it. In a clear PET can, every bit of that shows in the grab-and-go fridge. In an opaque can, boba is just a beige liquid with a label doing all the work.
The seal protects the look, too. The can never spins during sealing: the seaming head rotates while the can stays still, so the brown sugar streaks and the milk-over-tea gradient come out of the machine exactly as poured. A layered drink is the whole merchandising pitch here, and it survives the seal untouched.
And a canned boba travels the way a cup with a dome lid never will. It rides in a bag, stocks a home fridge, and sells a second unit to the customer who already ordered one at the bar.
The same short list as any drink canning program: a countertop can sealer, empty cans with lids, and fridge space. Canned machines start at $1,799 for the one-button automatic, with free shipping and Affirm or Klarna at checkout; the $1,899 Pro adds a touch screen for back-to-back batch runs. Both seal a clear PET can in a few seconds.
Boba goes in the 16 oz can, the same size as your large cup. It starts at 99 cents by the case with the lid included and drops to 74 cents on Canned Club subscription volume. The 8 oz size makes a strong tea-flight or kids' pour, and the machine adjusts to any can height itself: the platform raises each can from 4 to 16 oz to the seaming head, no spacer discs, so mixing sizes in one batch run is no changeover at all.
One boba-specific tip: toppings go in first, cold tea over, seal cold. A chilled fill keeps the gradient sharp and the can condensation-free for the fridge.
This is the honest part of the guide: tapioca pearls do not love the fridge. Cooked tapioca starts to firm up within hours of refrigeration and is noticeably chewy-going-on-hard within a day. The tea is fine for days; the pearls are not. Every shop canning boba picks one of three plays:
| Strategy | How it works | Best for |
|---|---|---|
| Sell pearl cans same day | Can with fresh pearls in the morning, date for today, discount at close | High-traffic shops that clear the fridge daily |
| Add fresh pearls at pickup | Can the milk tea alone, drop hot fresh pearls in a cup or side pot when the customer grabs it | Preorders, app pickup, and office runs |
| Use toppings that hold | Grass jelly, lychee jelly, agar pearls, and popping boba keep their texture for days refrigerated | Multi-day fridge stock and wholesale accounts |
Pearl texture is a quality issue, not a safety one. The tea's refrigerated window still applies either way.
House-canned boba is fresh product, not shelf-stable product. The seam keeps oxygen out and carries your fridge life, it does not replace refrigeration. Milk tea follows the same windows as any dairy or alt-dairy drink; the toppings set the shorter clock:
| Product | Storage | Quality window |
|---|---|---|
| Milk tea or alt-milk tea, canned | Fridge, 40°F or below | 3 to 5 days |
| Milk tea with tapioca pearls, canned | Fridge, 40°F or below | Same day for texture; the tea itself holds longer |
| Tea with jelly or popping toppings, canned | Fridge, 40°F or below | 3 to 5 days |
| Any canned drink left at room temperature | Counter | Treat as same-day |
Conservative quality windows for unpasteurized, refrigerated product. Date every can and follow your local health department's rules.
Yes, under the same rule as every fresh canned drink: the can is a to-go cup with a better lid, not a preservation method. Keep it at 40°F or below, date every can, and sell inside the windows above. What you cannot do is treat an unpasteurized milk tea as shelf-stable at room temperature.
Boba's quirks are quality quirks, not safety ones. Pearls harden, tea and milk separate into a layer line, and brown sugar settles; all normal, and a shake-before-opening note on the label sets the expectation for everything except the pearls, which nobody shakes back to soft. Our food safety guide covers the handling details.
Boba already carries the best pricing power in cold drinks, so run the math at $6.50 to $7.50 a can. The 16 oz can and its lid start at 99 cents by the case and drop to 74 cents on subscription volume. Ingredients land around 75 cents to $1.25: brewed tea for pennies, milk or creamer at 30 to 50 cents, sugar or syrup, and the topping, with tapioca among the cheapest toppings you stock.
That puts total product cost around $1.75 to $2.25, so a $7 can returns roughly $4.75 to $5.25 gross, a 68 to 75 percent margin, better than most cup sales once you count the dome lid, the fat straw, and the sealing film you did not use.
Six cans a day at $5 gross is about $900 a month, which clears the $1,799 machine in two months. And boba buyers are already multi-unit buyers: the customer picking up four cans for a study group is the same one who orders a round of cups today.
Let the pearls face the room. Stock the cans so the topping layer shows at eye level, and put the boldest visual, brown sugar streaks or a jelly layer, at the front of the row. A fridge full of visible pearls stops foot traffic in a way no poster does.
Sell the same-day story instead of hiding it. A shelf card that says canned this morning turns the short pearl window into a freshness claim, and an end-of-day discount on pearl cans clears the fridge while training customers to come back early.
Start with stickers from your label printer: flavor, sell-by date, keep-refrigerated, shake before opening. Once a flavor earns a permanent slot, custom printed clear cans from 1,000 units put your logo on the can while keeping the pearls visible, which is the entire point of going clear.
They stay safe but not soft: refrigerated tapioca firms up within hours and is hard by the next day. Sell pearl cans same day, add fresh pearls at pickup, or switch multi-day stock to jelly and popping toppings that hold their texture.
The full-open lid: the entire top peels away, so a wide boba straw or a spoon fits with no cutting. Standard pull-tab lids work for pearl-free teas people sip like a soda.
Yes. Popping boba, grass jelly, lychee jelly, and agar pearls all hold their texture for days refrigerated, which makes them the go-to toppings for cans that need to sit in the fridge more than a day.
The 16 oz matches your large cup and carries the toppings best, so it is the standard. An 8 oz works for tasting flights and kids' pours, and every size seals on the same machine.
No. The seam keeps oxygen out, which protects tea aroma better than a filmed cup. Brew strength and a cold fill matter far more than the container; separation is normal and shakes back in.
Not hot fills, and not carbonated drinks in today's clear PET cans (the seamer itself seals carbonation-rated cans, and carbonation-ready cans are coming). Every cold milk tea, fruit tea, and slush-free house special cans perfectly today.
