Meat is a high-value food product, and ensuring its quality, safety, and appeal throughout the entire supply chain—from production to consumption—is critical.
As consumer demand for purchasing meat while guaranteeing freshness and convenience continues to grow, meat packaging methods are constantly innovating. Packaging solutions emphasizing recyclability, reduced material usage, and lower carbon footprints are gaining significant attention.
Meat packaging involves various materials and processes designed to maintain freshness, safety, and flavor, minimize contamination, extend shelf life, and make meat products more accessible to consumers.
This guide explores the types, advantages, and trends in meat packaging, along with how to select the right packaging approach for your business.
Common Methods of Meat Packaging
Selecting appropriate packaging materials and techniques is crucial for preserving the freshness and safety of meat products, necessitating the use of suitable packaging methods tailored to different types of meat.
Vacuum Packaging
Vacuum packaging involves removing air from the packaging before sealing it, preventing external oxygen from entering to extend shelf life and maintain food freshness.
Vacuum packaging isolates oxygen, thereby inhibiting the growth of fungi, mold, and oxygen-dependent bacteria, achieving the goal of preserving food freshness.
Vacuum-packed meat does not exhibit the bright red color seen in traditional packaging because meat synthesizes oxygenated myoglobin when exposed to oxygen, resulting in a darker hue. By significantly reducing oxygen content, vacuum packaging preserves the meat’s color more stably. Compared to improvements in freshness and quality, consumer acceptance is also higher.
Vacuum packaging also helps reduce cross-contamination and prevents odors from other items in your refrigerator or home.
Vacuum packaging prevents dehydration and freezer burn in meat. By eliminating all oxygen, moisture cannot evaporate, preserving the original tenderness and juiciness for superior texture and flavor.
Vacuum Skin Packaging
Vacuum skin packaging involves covering thermoformed trays or molded plastic containers with a thin layer of plastic film that clings to the product like a second skin. This tension-free wrap preserves the product’s natural appearance, effectively maintaining quality and enhancing its appeal on retail shelves.
Vacuum skin packaging prevents food exposure to oxygen, thereby preserving the aroma, color, and nutritional value of packaged products.
Vacuum skin packaging supports and protects products during transportation, storage, and display. It secures food items in place, withstanding the unpredictability of supply chain distribution, transit, and in-store handling. This ensures customers receive aesthetically pleasing products free from damage incurred during shipping.
Modified Atmosphere (MAP）
Using the modified atmosphere (MAP) technology in packing is one of the most effective ways to protect and preserve the meat products.
Thanks to the fact that the air in the packaging is replaced with a gas mix, the meat manufacturers may completely get rid of microorgan-isms developing in the packaging, which in turn would improve the longer product freshness.
Modified atmosphere packaging can replace the natural gases within the package with an atmosphere suitable for specific products, but the chemical processes occurring during product storage must be taken into account.
Thermoforming Films
Thermoforming films are widely used in the food processing industry due to their high production capacity. The film is heated and stretched to form pouches. After filling the pouches with products, you can choose vacuum sealing, gas flushing, or direct sealing.
Our new thermoforming films offer high transparency and clear gloss. They showcase product quality to consumers through tight, wrinkle-free packaging and protect products during distribution and transportation.
Vacuum Shrink Packaging
Shrink bag is made from shrink film. The process is that the film edge is tightly wrapped around the product after vacuuming and being put in water heating to 85-90 ‘c.The excellent elasticity ensures the perfect packing.
Shrink bags offer exceptional clarity, outstanding strength, and superior sealing performance, designed to provide ultimate protection while maximizing shelf life and maintaining the product’s fresh appearance. They are ideal for packaging boneless and bone-in half-cuts of beef, pork, and lamb.
Tray Packaging
Refrigerated meat sold in supermarkets is typically presented on polystyrene trays. Absorbent paper is placed at the bottom of the tray to soak up meat juices, making the meat appear exceptionally bright red and stimulating consumers’ desire to purchase.
Common transparent film materials include the following:
Cellophane: One side is coated with nitrocellulose. When this side contacts the meat, it absorbs surface moisture until saturated, promoting oxygen permeation to maintain excellent color and reduce weight loss.
Polyethylene: Highly permeable to oxygen, it also offers excellent resistance to acids and alkalis, oil, and water vapor transmission, making it highly suitable for fresh meat packaging.
Aluminum foil
Can be laminated with other materials to create flexible packaging for frozen foods, or processed into semi-rigid containers of various shapes for packaging meat or ready-to-eat foods.
It offers excellent resistance to water vapor and gas permeability, but has poor shrinkability and heat sealability.
Canned Packaging
Canned meat packaging utilizes non-permeable materials and undergoes high-temperature sterilization to ensure long-term storage at room temperature.
Room-temperature meat products undergo sterilization at 121°C or higher, guaranteeing a minimum shelf life of six months for convenient distribution. This packaging isolates air and microorganisms while preserving nutritional value and flavor.
Canning extends shelf life and reduces cold chain requirements. It enhances food safety by preventing contamination, supports export capabilities, and facilitates global distribution. Its portable design suits outdoor consumption.
Packaging Methods for Different Meats
Effective meat packaging mainly relies on methods such as vacuum sealing, modified atmosphere packaging (MAP), and tray overwrap, which help maintain freshness, extend shelf life, and preserve the quality of various types of meat.
Each packaging corresponds to different functions and characteristics. Below, we will analyze the packaging for different types of meat.
Chicken Packaging
Chicken, as poultry, benefits from methods that address its high moisture content and sensitivity to bacterial growth such as Salmonella.
Vacuum Packaging – By removing air and using barrier films to create an anaerobic environment, it saves space, inhibits bacteria, and extends shelf life.
Modified Atmosphere Packaging (MAP) – Maintains meat color and tenderness, extends shelf life and storage time.
Shrink Bags – With puncture resistance and heat-sealing properties, they conform to the shape, effectively extend shelf life and enhance product visibility, reduce weight loss and inhibit microorganisms.
Beef Packaging
The focus of beef packaging is to maintain the red color and prevent dripping, extending the shelf life of cuts such as steaks.
Vacuum Sealed – By using vacuum bags to remove air, it prevents abrasion, moisture migration, and gas penetration, inhibits bacterial growth, extends shelf life, and saves space.
Modified Atmosphere Packaging (MAP) – Modified atmosphere packaging stores beef products in an environment other than air, sealed with transparent high-barrier films, and can combine different gases in appropriate proportions for various functions.
Traditional Packaging – This packaging consists of a foam tray used to hold the beef and an absorbent pad, wrapped with transparent breathable plastic film. This packaging is very economical, and the equipment used is also cost-effective, but the shelf life is very short and it cannot inhibit the growth of spoilage bacteria.
Pork Packaging
Paper Packaging – Paper packaging uses freezer paper for airtight sealing, usually with double-layer sealing, suitable for regularly shaped meat blocks, but it is more difficult for bone-in pork chops and irregularly shaped meat.
Vacuum Sealing – Vacuum packaging is an efficient packaging method that provides tight protection, strong puncture resistance, prevents freezer burn, maintains freshness, and extends shelf life.
Modified Atmosphere Packaging (MAP) – Inhibits bacterial growth, stored at 0°F, prevents cross-contamination, uses food-grade materials, with clear labeling.
Sausage Packaging
Sausage packaging comes in various forms, each with its specific uses. The most common types include vacuum packaging, modified atmosphere packaging (MAP), natural casings, and thermoformed films.
Vacuum Packaging – This method requires evacuating the air inside the package before sealing. Vacuum packaging can reduce the oxygen content required for spoilage bacteria reproduction, thereby significantly extending shelf life.
Modified Atmosphere Packaging (MAP) – Modified atmosphere packaging replaces the air inside the package with a specific gas mixture (usually carbon dioxide and nitrogen). It can maintain the texture and color of the sausage.
Thermoformed Films – This method requires heating plastic sheets to form them, tightly wrapping the product. The formed plastic is then cooled and trimmed to create a sealed package.
Natural Casings – The simplest and quickest method for filling sausages with natural casings, using convenient plastic sleeve packaging, coated with salt, easy to slide into the filling tube.
Frozen Meat Packaging
Proper frozen meat packaging is important, as it can maintain texture, flavor, and color, extend shelf life, and prevent contamination.
Vacuum Sealing – Removes almost all air, prevents freezer burn, can be stored in portions, saves space, and protects product quality.
Double-Layer Packaging – Tightly wrap the meat with plastic wrap, then add a second layer with aluminum foil or heavy-duty freezer bags, reducing contact with air, which is also a good packaging method.
Processed Meat Packaging
We understand that protecting smoked meats from moisture, oxygen, and contaminants, while maintaining their flavor and appeal, is crucial.
Thermoformed Films – This packaging simplifies the production process, reduces waste, and provides products that are fresh in appearance and taste.
Shrink Bags – Sealed packaging through high-barrier films, durable and aesthetically pleasing.
Which Type of Packaging Is Best Suited for Meat?
The optimal packaging type for meat depends on the meat variety, intended shelf life, and distribution channels. A key factor is the product’s shape and specifications, so there is no definitive answer regarding which packaging is best.
Selecting appropriate packaging based on specific products is ideal, leveraging the characteristics of different materials. This significantly impacts packaging quality, product integrity, and overall packaging process efficiency.
For supermarkets, MAP and VSP are more suitable options. Both effectively showcase the freshness and quality of meat products, while VSP lends a more premium appearance to the items.
Vacuum packaging maintains optimal color stability. For MAP, although gas flushing can be used as a safeguard, there remains a chance of color deterioration, which may reduce consumer appeal.
Vacuum packaging, modified atmosphere packaging (MAP), vacuum skin packaging, and shrink wrapping all help extend shelf life and enhance product appearance.
However, each packaging method has its own advantages. For instance, vacuum packaging maintains color stability, while MAP requires consideration of meat type, quality, production process, and storage conditions—different conditions yield different results.
Ultimately, selecting the optimal packaging based on your specific product is the correct approach.
