The meat packaging industry is gradually shifting towards flexible packaging solutions.
This trend is driven by the need for more efficient, sustainable, and consumer-friendly packaging options. Flexible packaging offers many advantages over traditional rigid packaging. These benefits include extended shelf life, reduced material usage, and increased convenience for retailers and consumers.
The development history of meat food is closely related to the development of packaging technology, the main one is related to flexible packaging technology. The technological innovation of the meat industry requires the support of flexible packaging technology. On the contrary, the emergence of new flexible packaging technology also promotes the development of the meat industry.
The packaging of meat products is mainly based on the different shapes of the products. Different specifications and types determine the different packaging forms.
Vacuum shrink packaging is a high-barrier packaging film that can be used for beef, pork, mutton, poultry, seafood, dairy products, and processed meat. Its high barrier and high shrinkage properties can significantly extend the storage time of fresh meat and expand the shelf life of fresh meat. Meat logistics radius. Vacuumed food bags need to have low-temperature toughness, puncture resistance, abrasion resistance, oxygen barrier, heat sealability, shrinkage, tear ability, transparency and gloss, printability, heat resistance, and meat products Adhesion, and many other comprehensive properties. It is a multi-layer co-extruded film that combines functional layers such as an anti-wear outer layer, an oxygen barrier layer, an anti-puncture layer, and a sealing layer within a thickness of tens of microns.
Retail Packaging
Modified atmosphere packaging (MAP) can maintain the original freshness and flavor of food, has a long shelf life, and good product appearance display effect, so it is widely used in the retail packaging of fresh meat and processed meat. Modified atmosphere packaging adjusts the gas composition of the environment in which food is placed to inhibit biological activity and color changes, and slow down the rate of deterioration, thereby maintaining food freshness and extending shelf life. High-barrier packaging materials can prevent protective gases from escaping or outside air from entering the packaging.
The trays used for modified atmosphere packaging can be high-barrier semi-rigid trays made by thermoforming, prefabricated trays, or high-barrier foam trays. There are two types of cover films used in modified atmosphere packaging: non-shrink cover film and shrink cover film. The shrink cover film has a shrinkage rate of 5%-40%. After shrinking through the heat sealing tunnel, a convex drum effect is formed above the tray, which can resist the loss of protective gas cause packaging collapse, and maintain good performance throughout the shelf life. packaging appearance.
Stretch film is a multi-layer film, usually non-shrinkable, that can be produced by multi-layer co-extrusion or dry lamination. During the stretch film packaging process, the bottom film is heated and formed into the shape of the container through heat stretching. The food is placed into the formed lower film cavity and vacuumed, and the upper film and lower film are heat-sealed to form a complete package... Stretch film is suitable for food that requires independent small packaging, while stretch film with medium barrier properties is used for packaging high-temperature sterilized meat products.
Skin Packaging
Skin packaging is a unique form of vacuum packaging. The upper film of skin packaging is a flexible film, and the lower film can be a multi-layer semi-rigid tray. Common materials include APET, PS, etc. During the skin-fitting packaging process, the product is placed on a semi-rigid lower film, and the upper film is heated to close to the melting point, softened, and then attached to the food surface under vacuum, which can perfectly replicate the three-dimensional structure of the food surface, forming Unique three-dimensional packaging effect. Skin packaging is very suitable for various deep-processing products.
