The evolution of food packaging has required advances in multi-layer plastic film technology, which has moved on from the traditional 5/7 layer design to more complex structures over the last few decades. This progress has been driven by the food industry's growing demand for better barrier properties. The emergence and popularization of 9-layer coextruded films has been a major breakthrough in the last five decades, and the successful application of 9-layer films has paved the way for more complex structures that push the boundaries of what is possible to achieve.
These high-performance multi-layer barrier films are essential for extending the shelf life of perishable products such as meat, cheese, poultry and fish, as well as for maintaining the freshness of refrigerated products such as nuts, milk powder, pet food and wine. The 9-ply films have a thinner nylon layer that provides greater flexibility than the 5- and 7-ply films, which have a thicker, stiffer nylon layer and a more rigid structure.
Multi-layer barrier film helps keep meat products fresh
Meat packaging involves wrapping meat products in multiple layers of barrier film material, which is an important step in protecting meat products from various environmental hazards. Initially, natural plant materials were used, but as technology progressed, synthetic and specialized barrier films were developed specifically for meat packaging.
These multi-layer barrier films protect meat from dust, microorganisms, bacteria and contaminants, prevent unpleasant odors, discoloration and flavor changes, and also regulate moisture content. It is important to note that bacteria are naturally present in meat, so it is necessary to take other measures along with packaging, such as refrigeration to stop or slow down microbial growth and sterilization, or heat to eliminate bacteria.
Typically, internal packaging of meat consists of direct contact between the meat and the barrier material, usually supplemented by external packaging in the form of cartons or other specialized materials. Different barrier films are used for internal packaging, ranging from translucent to thick, gas-impermeable to gas-permeable, and flexible to semi-rigid, each of which fulfills a specific function, including aesthetics and providing optimal protection for the meat using multi-layer barrier technology.
Flexible Packaging Materials For Healthy Food
The ready-to-eat and fresh meat sector is poised to witness the fastest and most significant growth, driven by a surge in demand for pre-cooked food options that cater to time-pressed consumers seeking economical meal solutions with minimal preparation time. This trend is fueled by a shift away from traditional grocery and retail outlets.
Advancements in flexible, shelf-life extending packaging tailored for container-ready products are expected to bolster growth in the fresh and frozen meat, seafood, and poultry markets. These packaging innovations help maintain product quality and extend shelf life.
Within the processed meat market, there's an increasing emphasis on premium, high-margin products designed for convenience. This focus is likely to drive growth and innovation in this segment.
