Picking a container for a new beverage line isn’t just a design decision — it locks in your cost structure, shelf life, distribution options, and how the product feels in a shopper’s hand before they’ve read a single ingredient. Aluminum cans, glass bottles, and PET plastic bottles each solve the packaging problem differently, and the ‘best’ one depends on what you’re selling and where.
This guide breaks down how the three formats compare on cost, weight and logistics, product protection, branding flexibility, and sustainability, so you can match the container to your product and your growth plan instead of just copying a competitor’s shelf.
Quick Answer
For most new and growing beverage brands, aluminum cans offer the best balance of cost, shipping efficiency, and shelf branding — which is why they’ve become the default for craft beer, seltzer, energy drinks, and RTD cocktails. Choose glass when you need a premium look or the best possible product protection for delicate flavors (wine, kombucha, some spirits) — but be deliberate about the glass color. Choose PET when cost-per-unit and shatterproof convenience matter most, such as bottled water, juice, or sports drinks sold in large multipacks.
Cost, Weight, and Logistics
PET is generally the least expensive material to produce and fill, aluminum cans sit in the middle, and glass is typically the most expensive of the three — the gap widens further once you factor in freight, since glass is heavy, needs dividers or trays to prevent breakage, and fits fewer units per pallet. Aluminum cans are lightweight and stack efficiently, which lowers your per-unit shipping cost and makes cold-chain and retail-shelf logistics easier. If you’re self-distributing regionally or shipping direct-to-consumer, that weight difference compounds fast.
On decorated unit cost, a printed 12-oz can generally runs cheaper than a comparably decorated glass bottle at typical introductory order minimums, though exact pricing depends heavily on your co-packer, order volume, and finish (labels vs. direct printing vs. sleeves). Get quotes from your specific can or bottle supplier before locking in a business plan — published averages are a starting point, not a quote.
Shelf Life, Product Protection, and Branding
Glass is essentially impermeable to oxygen, but it is not automatically a light barrier — that depends entirely on the glass color you choose. Clear (flint) and green glass let most visible and UV light through, while amber (brown) glass blocks the large majority of UV and short-wavelength light. That’s why beer, which is prone to developing a ‘skunky’ off-flavor from UV exposure, is almost always packaged in amber glass rather than clear or green. If you go with glass for a light-sensitive product, spec amber or another dark tint, or plan for secondary protection like an opaque box or sleeve. Aluminum cans, by contrast, are fully opaque on all sides and give you a strong oxygen and light barrier by default, which is part of why hop-forward beers and other light-sensitive RTDs increasingly ship in cans.
PET is more permeable to gas and light over time than either amber glass or aluminum, so it’s typically better suited to beverages with shorter shelf lives or higher turnover, like water and juice, rather than products that need to hold carbonation or delicate aromatics for many months.
For branding, cans give you 360-degree, edge-to-edge full-color graphics printed directly on the metal, which tends to stand out in a cold case and works well for brands that change designs or run limited editions frequently. Glass supports embossing, custom bottle shapes, and premium finishes (frosting, foil labels, textured or tinted glass) that can signal a higher price point. PET is the most flexible for custom bottle shapes at lower cost, but its printing is typically limited to labels or sleeves rather than direct decoration.
Tips / Common Mistakes
Don’t choose a format purely on sustainability messaging without checking the specifics: aluminum has strong recycling infrastructure and tends to see a high recycled content in most markets, but actual environmental impact also depends on your transport distances, local recycling access, and whether you’re using recycled material in your own containers. Verify local recycling and refill infrastructure for your target markets rather than assuming national averages apply.
Match the container to your beverage’s actual shelf-life and light-sensitivity needs — over-engineering with glass for a fast-turnover product wastes margin, and choosing clear or green glass for a light-sensitive product can undo the protection you thought you were buying. Also confirm minimum order quantities early: can and bottle suppliers often have very different MOQs and lead times, and glass in particular can involve longer lead times for custom molds, embossing, or tinted glass. Finally, test your actual filled product on-shelf and in transit (including summer heat for trucks and hot cars) before committing to a full production run.

Beverage packaging materials FAQs
Which is cheaper: aluminum cans or glass bottles?
Aluminum cans are generally cheaper than glass bottles per unit, and the gap grows once shipping is included, since glass is heavier and less space-efficient to freight. PET is usually the cheapest of the three materials.
Which packaging is best for a new beverage brand with a small budget?
Aluminum cans are the most common starting point for new craft and RTD brands because of their lower shipping costs, competitive unit pricing, and strong shelf branding, though PET can be a lower-cost option for water, juice, or sports drinks.
Does glass protect a beverage from light better than aluminum?
Only if you choose the right glass color. Clear and green glass transmit most visible and UV light, so they offer little light protection on their own. Amber glass blocks most UV and short-wavelength light, which is why it’s the standard for beer. Aluminum cans are opaque on every surface, so they block light fully regardless of the can’s printed color.
Is PET recyclable like aluminum and glass?
Yes, PET is recyclable, but it generally has lower recycling and closed-loop reuse rates than aluminum in most markets, meaning more PET containers end up down-cycled into other products rather than turned back into new bottles.
Can I switch packaging formats after launch?
Yes, many brands change formats as they scale — for example, moving from bottles to cans to reduce shipping costs — but switching requires new production line setup, artwork, and sometimes new co-packer relationships, so it’s worth planning your likely long-term format before your first big production run.
