Sausage Packaging: Innovations, Materials, and Solutions for Modern Needs

Sausages are a staple in global cuisine, available in countless varieties—from fresh bratwurst to smoked chorizo and shelf-stable frankfurters. However, their diverse textures, moisture levels, and preservation needs demand tailored sausage packaging solutions.

As a leading manufacturer of flexible plastic packaging, we deliver high-performance materials and designs that protect sausage quality, extend shelf life, and meet sustainability goals.

In this article, we will explore sausage classifications, packaging methods, material innovations, and how our factory supports this dynamic industry.

Types of Sausages

Sausages are broadly categorized based on processing methods and preservation requirements:

• Fresh Sausage:
  Fresh sausages, such as breakfast sausages, Italian salsiccia, with high moisture, are perishable and require refrigeration.
• Cooked/Smoked Sausages:
  Cooked sausages and smoked sausages are fully cooked, have a longer shelf life, and may require reheating. Frankfurters and kielbasa are some of the most famous cooked sausages.
• Dry-Cured/Fermented Sausages:
  Salami and pepperoni are dry-cured sausages, they are low moisture, preserved through fermentation.
• Vegetarian/Vegan Sausages:
  Vegetarian/Vegan Sausages like Plant-based protein links are sensitive to texture changes, often oil-rich.

Common Sausage Packaging Solutions

Different packaging techniques address unique challenges in sausage preservation and presentation.

We can select the most suitable packaging for sausages by considering the specific characteristics of each type of sausage.

Vacuum Packaging

• Process: Air is removed to inhibit bacterial growth.
• Best For: Fresh sausages, cooked and smoked sausages.
• Materials:
  1. PA/PE Coextrusion Film:
     It exhibits excellent mechanical strength and puncture resistance, along with superior oxygen barrier and moisture-proof properties.
     It is heat-sealable and suitable for automated packaging equipment, making it ideal for vacuum packaging fresh sausages, cooked sausages, and more.
  2. PA/EVOH/PE high barrier co-extruded film:
     It features high barrier properties, providing excellent resistance to gases such as oxygen and carbon dioxide, significantly extending the product’s shelf life with remarkable freshness preservation.
     It also offers high transparency and gloss, making it suitable for high-quality sausages or cooked products that require extended shelf life.
  3. PET/PE Laminated Film:
     It provides good mechanical strength and barrier properties.
     The PET layer offers excellent printability and optical performance.
     It is cost-effective and suitable for conventional vacuum packaging, making it an ideal choice for mass-market vacuum-packaged sausages.
  4. Polyvinylidene Chloride Coated Film (PVDC):
     It has excellent oxygen and moisture barrier properties.
     Outstanding chemical resistance, making it suitable for products with high moisture-proof and preservation requirements.
     Widely used for high-end sausage products and long-term storage packaging.
     

And how long does vacuum-packed sausage last in the fridge?

Vacuum-packed sausage can last up to 2 weeks in the fridge if it’s unopened and adequately stored at or below 40°F (4°C). However, always check the expiration date on the package.

Once opened, it’s best to consume the sausage within 3 to 5 days for optimal freshness and safety.

For longer storage, vacuum-packed sausages can be kept in the freezer for up to 1 to 2 months.

Modified Atmosphere Packaging (MAP)

Modified atmosphere packaging can effectively inhibit microbial growth, delay oxidation reactions, and preserve the flavor and texture of sausages.

• Process: Replaces oxygen with nitrogen or CO₂ to slow oxidation.
• Best For: Fresh sausages, premium cooked sausages, and fermented sausages.
• Materials:
  1. Multi-layer Coextrusion Film likes PA/PE、PA/EVOH/PE、PET/PE .
     With excellent barrier properties, it effectively blocks oxygen, carbon dioxide, and moisture.
     It boasts high mechanical strength and superior puncture resistance.
     It is ideal for vacuum packaging or gas-flush packaging (such as CO₂ and N₂ mixtures) for sausage packaging with high barrier requirements, such as premium cooked sausages and fermented sausages.
  2. Laminated Film: such as PET/PE、PET/Al/PE、BOPA/PE.
     It provides excellent barrier properties and mechanical strength.
     The PET layer offers superior printability and optical transparency.
     An optional aluminum foil layer can be added to enhance barrier effectiveness.
     It is primarily used for tray sealing or pouch packaging.
  3. High barrier films with precise gas permeability (e.g., EVOH layers).
     It is particularly suitable for high-quality sausages that require long-term preservation.
  4. PP or PE: It is primarily used for tray-sealing packaging in combination with high-barrier films.
     It offers excellent heat-sealing properties and is suitable for pre-formed trays paired with lidding films.
     It is commonly used for tray packaging of refrigerated or frozen sausages.

Bag Packaging

• Process: Sausages are placed in pre-formed or stand-up pouches, often with resealable zippers.
• Best For: Pre-sliced sausages, bulk retail packs, or gourmet products requiring a premium presentation.
• Materials:
  1. PET/PE Laminated film:
     Provide excellent mechanical strength and transparency.
     Suitable for printing, and enhancing product visual appeal.
     Low cost, suitable for mass-market products.
     Applied to the bag packaging of regular sausages or refrigerated sausages.
  2. Aluminum Foil Laminated Film:
     Completely blocks light, oxygen, and moisture.
     Provides optimal protection and extended shelf life.
     The higher cost is mostly used for premium products.
     Applied to the packaging of fermented sausages or high-quality cooked sausages.

Thermoforming Packaging

• Process: Plastic sheets are heated and molded into trays or clamshells, then sealed with a film lid.
• Best For: Premium sausages, ready-to-eat meals, or deli-style sliced products.
• Materials: APET/PE, PP, or recyclable PET trays paired with high-barrier lidding films.

Shrink Packaging

• Process: Heat-sealed films shrink tightly around sausages.
• Best For: Bulk packaging of linked sausages.
• Materials: Polyolefin shrink films.

Natural Casings

• Process: Traditional animal intestines (hog, sheep) or collagen casings.
• Best For: Artisanal dry-cured sausages.
• Limitations: Limited shelf life, higher cost.

Flow-Wrap Packaging

• Process: Automated horizontal wrapping for individual portions.
• Best For: Snack-sized vegan sausages.
• Materials: PET/PE laminates for clarity and durability.
