Selecting the right can—and the right seaming method—starts with your product. Food and beverage formulas, pharmaceuticals, nutraceuticals, industrial goods, and specialty items all place different demands on packaging. This guide walks you through the key decisions: product chemistry, processing method, can construction, lid options, and seam technology. We’ll also show where Dixie Canner equipment fits so you can move from concept to production with confidence.
Start with the product: formula, pH, and process
1) Know your product and pH.
Your can’s internal lining must be compatible with the product’s acidity/alkalinity (pH), fats/oils, alcohol, and flavor compounds. Acidic foods (low pH) often require different lacquers/linings than neutral products. If you’re unsure, request lining recommendations and Can Manufacturer’s Seam Specifications from your supplier.
2) Confirm if thermal processing is required.
Many shelf-stable foods need retort processing (thermal processing) to ensure safety and stability. Your target F₀ / lethality, texture, and appearance drive can and lid choices. Some beverages and dry products may not need retort but still benefit from vacuum or inert-gas packaging.
3) Define your oxygen strategy.
If flavor and freshness are oxygen-sensitive (coffee, nuts, seafood, botanicals, nutraceuticals), plan for vacuum and/or inert gas flush prior to seaming. This helps lock in quality and extend shelf life.
Why choose can applications over alternative packaging
-
Increased operational efficiency: Rigid cans fill faster and more accurately, improving line throughput.
-
Durability: Cans stack without damage, saving space in storage and transport.
-
Shelf stability: Cans support longer shelf life, whether via retort or controlled-atmosphere seaming.
-
Sustainability: Aluminum and steel cans are endlessly recyclable, supporting circular economy goals.
Can package options (materials, shapes, and ends)
Materials & constructions:
-
Aluminum & metal cans: Excellent barrier to light and oxygen, ideal for beverages, seafood, meats, and many processed foods.
-
Composite cans (paper with barrier liners): Lightweight, great for dry goods (coffee, powders, snacks).
-
Plastic cans: Useful where visibility or specific form factors are required.
Specialty lid/end options:
Peel-Off, EZO (Easy-Open), Sanitary, CDL, LOE, dome-type, and cartridge/nozzle formats. Match the end to product viscosity, consumer convenience, and processing needs (e.g., easy-open for RTD beverages, cartridge for adhesives).
Extended shelf life routes
-
Thermal processing (retort): Heat-treat sealed cans to achieve shelf stability in low-acid and many prepared foods.
-
Vacuum & gas flush: Reduce oxygen prior to seaming for oxygen-sensitive products (coffee, nuts, seafood, nutraceuticals).
-
Hermetic double seams: The mechanical closure that keeps light and oxygen out, preserving quality.
Wide range of products that can shine in cans
-
Food & Beverage: Fruits, vegetables, meats & seafood, soups, beer, wine, soft drinks, RTD, nutritionals, coffee and tea.
-
Pharma/Nutraceutical/Devices: Formulas, supplements, and certain devices benefit from controlled atmospheres and robust protection.
-
Industrial: Lubricants, cleaners, adhesives, caulking cartridges, capacitors, paints/solvents (with proper linings and ends).
-
Specialty/Gourmet: Coffee and tea (vacuum/gas flush), dried fruit & nuts, bakery mixes, caviar/crab/oysters (with vacuum/thermal options).
Understanding why can seam technology works
A double seam (can seam) hermetically roll-forms the body flange and lid curl into five layers of plate material, then compresses them into a gas- and liquid-tight closure. Quality seams are repeatable and measurable (cover hook, body hook, overlap, countersink, tightness). For oxygen-sensitive products, Dixie Canner’s Vacuum and Gas Flush options complete the atmosphere-control cycle before the seam is made—so you lock in your target environment and then seal it hermetically.
Matching your application to the right can and seamer
Aluminum & metal cans
-
Best for: Beverages (including RTD coffee/tea), seafood, meats, prepared foods.
-
Why: Superior barrier to light and oxygen, compatible with retort, broad end options.
-
Recommended seamers:
-
Dixie Double Can Seamers: Hermetic closures on round, rigid containers across sizes and materials.
-
Dixie Vacuum Can Seamers: Add vacuum, gas flush, multi-flush, and timed delays for oxygen control.
-
Dixie Direct Drive Can Seamers: Tough, precise, and easy to sanitize; 10–30 cpm depending on model.
-
Composite cans (with metal/plastic ends)
-
Best for: Coffee (whole bean/ground), nutrition powders, snacks, dry mixes.
-
Why: Lightweight, cost-effective; pair with vacuum/inert gas seaming for freshness.
-
Recommended seamers: Vacuum-capable seamers (e.g., UVGMD-class) to hit low-oxygen targets.
Plastic cans & specialty lids
-
Best for: Visibility or dispensing needs; industrial cartridges with nozzle ends.
-
Why: Form-factor flexibility; pair with the right end and seaming tools for a secure closure.
-
Recommended seamers: Validate end compatibility; dome-type lids and small diameters can be accommodated with change parts.
Vacuum-packed cans
-
Best for: Oxygen-sensitive items (coffee, nuts, seafood, botanicals).
-
Why: Vacuum and gas flush reduce oxidation; multi-flush can further reduce residual O₂.
-
Recommended seamers: Dixie Vacuum Can Seamers with multi-flush and timed delays.
Equipment that supports your decision
-
Dixie Double Can Seamers – Hermetically seam lightweight metal tops onto round, rigid containers in a wide range of sizes, types, and styles. Perfect alignment, interlocking seam rolls with the chuck, and no-spill operation (container turns only during seaming).
-
Dixie Vacuum Can Seamers – Chambered systems with vacuum, gas flush, multi-flush, and timed delays to tailor oxygen levels before the seam.
-
Dixie Direct Drive Can Seamers – UL/CE listed, rust-resistant, easy to clean, and fast—ideal for beverage and industrial lines needing reliable throughput.
-
Retorts & thermal processing – For products requiring shelf-stable sterility, pair seamers with Dixie RDSW-3SS Retort and controls for repeatable processes and records.
Practical selection checklist
-
Product & pH: Confirm chemistry and lining compatibility; get supplier guidance and seam specs.
-
Process: Determine if you need retort, hot-fill, or controlled-atmosphere packaging (vac/gas flush).
-
Can & end type: Choose aluminum/steel, composite, or plastic; select end style (EZO, sanitary, peel-off, dome, cartridge, etc.).
-
Shelf life target: Set oxygen goals; plan for vacuum, single flush, or multi-flush routines.
-
Seamer fit: Match can diameters/heights and end types to seamer capability; plan change parts for SKU flexibility.
-
Scale & speed: Align CPM and footprint with your current line and near-term growth.
-
Compliance & QA: Ensure data logging, teardown inspection, and maintenance cadence meet your standards.
When in doubt, ask (and test)
Most can suppliers will review your formula and recommend can bodies, ends, and linings. They’ll also provide Can Manufacturer’s Seam Specifications so your QA team has the teardown targets. For oxygen-sensitive applications, run pilot trials with vacuum and gas flush profiles to verify product quality and shelf life before scaling.
