Clear PET cans show the drink, seal with the same standard aluminum lids as a regular can, and suit fresh refrigerated café product sold within days. Aluminum cans block all light, take pasteurization, and suit shelf-stable retail product distributed through a co-packer. For a café selling cold brew, matcha, and tea from its own fridge, clear PET wins: the drink merchandises itself, cans start at 70 cents with lids included, and they seal on a $1,799 countertop machine.
Because a café can and a grocery can do different jobs. A grocery can survives months of ambient shelf life, trucks, and warehouses; nobody who buys it has ever seen the liquid inside. A café can sells itself from a fridge three feet from the register to a customer deciding in about two seconds.
Aluminum was engineered for the first job. Clear PET, a food-grade recyclable plastic with an aluminum lid seamed on top, was made for the second: the layered latte, the green of a matcha, the cascade of a cold brew all do the marketing before anyone reads a label.
| Clear PET can | Aluminum can | |
|---|---|---|
| You can see the drink | Yes, that is the pitch | No |
| Lid and seam | Standard aluminum end, double seamed | Standard aluminum end, double seamed |
| Light protection | None; keep it in the fridge, sell it fresh | Total |
| Product model | Fresh, refrigerated, dated, days | Pasteurized, shelf-stable, months |
| Sealing equipment | Countertop seamer from $1,799 | Crowler seamers or production lines |
| Cost per can, café volume | 70 to 99 cents by the case, lids included | Cheap in bulk, high minimums for small printed runs |
| Branding | Custom printed clear cans from 1,000 units | Printed runs typically start in the tens of thousands |
PET pricing is Canned blank-can entry pricing by size; subscription volume brings it lower.
Yes, and this is the detail that makes café canning possible at all. A clear PET can necks to a standard aluminum end and closes with the same double seam as an all-aluminum can. The customer gets the familiar crack of a pull tab; the operator gets a real hermetic seam, not a snap-on cap.
On the Canned line every size, 4, 8, 12 and 16 oz, necks down to the same 55mm mouth, so one countertop machine seals all four with no changeover. Lids are included with the cans, and pull-tab, full-open, and peel-off ends cover different drinks: full-open for anything sipped like a cup, peel-off for tamper-evident freshness.
Both materials keep oxygen out; the double seam does that work, and it is the same seam on both. The real difference is light: aluminum blocks all of it, clear PET blocks none of it by design, because seeing the drink is the point.
For shelf-stable product that will sit under store lighting for months, light matters and aluminum is correct. For a café can that lives in a fridge and sells within days as dated fresh product, light exposure is measured in hours and the visibility is worth far more than the protection. Match the material to the product model and both answers are right.
Aluminum is the champion here, honestly stated: it recycles endlessly with no quality loss, and roughly half of aluminum cans actually get recycled in the US. If a drink's whole identity is sustainability at retail scale, aluminum has the stronger story.
Clear PET is the most widely accepted plastic in curbside recycling, the same #1 resin as a water bottle, and a clear unpigmented body is exactly what recyclers want. Real US recycling rates for PET run lower than aluminum's, so the fair summary is: both are recyclable, aluminum gets recycled more. The aluminum lid on a PET can recycles like any can end.
One more honest note: a café canning in-house replaces single-use cold cups and lids, which is the packaging it actually competes with behind the counter, not the retail aluminum can.
Blank clear PET cans from Canned run by the case with lids included: 70 cents for the 4 oz, 80 cents for the 8 oz, 86 cents for the 12 oz, and 99 cents for the 16 oz at entry volume. Larger orders bring each size down, and the Canned Club subscription takes the 16 oz to 74 cents and the 4 oz as low as 57 cents.
Bulk aluminum is cheaper per unit at truckload quantities, which is why retail brands use it. The catch is access: printed aluminum runs typically start in the tens of thousands of cans, and small-batch aluminum bodies for taproom-style seamers land in the $1 to $2 range per can. At café volume, a case at a time, clear PET is both the cheaper and the only practical option.
Branding follows the same split. Custom printed clear cans start at 1,000 units at 95 cents to $1.25 per can, designed in the online studio, so a café can put its logo on a real printed can at a volume it will actually sell.
Clear PET, fresh and refrigerated: cold brew, iced lattes, matcha, chai, iced tea, lemonade, juice. Anything still, cold, and good looking. These sell on sight and move within days, which is exactly the window dated fresh product wants.
Aluminum, through a co-packer: pasteurized shelf-stable recipes and anything headed to grocery distribution. Retort pasteurization is production-line territory; a countertop café setup should not attempt it. Carbonated drinks need a pressure-rated can, which today means aluminum or the carbonation-ready cans coming to the Canned lineup.
The honest decision rule: if the drink is made in your shop and sold from your fridge, clear PET. If it is leaving your building for someone else's shelf, aluminum through a production line.
Yes. PET is the same food-grade #1 resin used for water and juice bottles, sealed with a standard aluminum end. Treat the contents like any fresh café drink: refrigerated, dated, and sold within its quality window.
Today's Canned clear PET cans are made for still drinks: coffee, matcha, tea, lemonade, juice. Carbonation takes a pressure-rated can; the seamer itself seals those, and carbonation-ready cans are coming to the lineup.
No. They seam with standard aluminum ends, included in the per-can price. Options are a pull tab, a full-open end, or a tamper-evident peel-off, plus snap-on overcaps for drinks that get sipped over time.
The same as it would in an aluminum can without pasteurization: it is fresh product. Refrigerated black cold brew holds 7 to 10 days; milk and alt-milk drinks 3 to 5. The can carries your fridge life, it does not replace refrigeration.
Yes. Custom printed clear cans start at 1,000 units, from 95 cents to $1.25 per can depending on volume, with about a 40-day lead time. Blank cans plus stickers cover you until a recipe earns a printed run.
