It consists of minimum two layers. It helps maintain the freshness and aroma of the foods, and is good for protection from radiation, oxygen, moisture, oils, and microorganisms [7]. Plastics are the most important class of packaging materials. 431-467. Nr.3. Each type of plastic has a code of its own approved by the Food and Drug Administration in the US. Journal of Agricultural and Food Chemistry, 57(18), 8089–8092. Foods packed in glass containers range from coffee, to dairy products, spices, spreads, syrups, processed vegetables and fruits, and meat and fish products [15]. Fibreboard is used to ship bulk food due to its strength and resistance to impact scratching and crushing damage [11]. Plastic bags are the raw material that is produced from the byproducts of crude oil, and it can be recycled in many ways. Their relative impermeability for substances from the surroundings has great influence on the shelf life and the quality of the packed goods. Lightweight plastic packaging also contributes to lighter truck loads, which helps reduce the energy used for transportation, lower shipping costs and reduce the amount of waste generated. (2016). (2007). Surface treatment, heat treatment and annealing are subsequent steps in the production process. This way of producing a foil with natural minerals saves 40% CO. Information retrieved from Ref. Soft-drinks, seafood, and pet-food are commonly enclosed by aluminium packages. PP Chalk is the environmentally friendly version of polypropylene (PP). Polyethylene terephthalate (PETE or PET) is a lightweight plastic that is made to be semi-rigid or rigid which makes it more impact resistant, and helps protect food or liquids inside the packaging. Depending on its method of production and packaging purpose, paper can be found as Kraft paper, sulphite paper, greaseproof paper, Glassine, or parchment paper. fresh salads, fruits, cold meats, snacks, etc. [15] Grayhurst, P. & Girling, P.J., (2011). Hereâs what to know. Given the packaging’s main purpose of preservation, containment, and protection of food, the packaging material can be rigid, flexible, or semi-flexible [3]. Recyclable packaging is manufactured from food grade recycled plastics, with full food packaging contact approval in a range of materials. Their relative impermeability for substances from the surroundings has great influence on the shelf life and the quality of the packed goods. Plastic containers and packaging protect against the contamination of food and offer adequate mechanical strength. Upon coating or waxing, their applications extend to packaging and serving of wet and fatty foods [5]. Some aluminium grades used in food packaging include AA 3003 (O, H22, H24), AA 8006, AA 8011, AA 8079, and AA 1235 [8]. Present and Future of Biodegradable Polymers for Food Packaging Applications. Glass is well-known for being amid the most reliable and least toxic materials for packaging foods and drinks. JFE Steel Corporation. Glass bottles are commonly used for alcoholic drinks, soft drinks, and potable water. Alloying elements, such as magnesium and manganese, are sometimes added to aluminium to enhance its strength. PP can be recycled into new raw material for non-food purposes. Thermoplastics, on the other hand, soften when heated and are able to retain their initial conditions at room temperature. Plastic has multiple uses and provides light, innovative materials that solve a variety of challenges. OPS can be recycled into new raw material for non-food purposes. Oriented polystyrene (OPS) is produced by stretching the extruded polystyrene foil, which makes the material stronger – or in this case harder – and improves visibility through the material. When people buy food products, they donât always think about the packaging that their food comes in. We connect engineers, product designers and procurement teams with the best materials and suppliers for their job. It has good resistance to heat and black sulphide stain, which makes convenient for making fish cans [9]. Plastics are organic polymeric materials that can be molded into the desired shape. Retrieved from: https://www.cmog.org/article/glass-romans. The safety of all materials used for packaging foods is controlled under Division 23 of the Food and Drugs Act and Regulations, Section B.23.001 of which prohibits the sale of foods in packages that may impart any substance to the contents which may be harmful to the consumer of the food. Retrieved from: https://alfipa.com/applications/aluminum-foil-laminates-food-packaging/, [8] (n.d.). Safety aspects of nanotechnology applications in food packaging. The plastic material is primarily used for food packaging that requires glass-clear quality, e.g. Chipboard is the cheapest form of paperboard, made of recycled paper, and is used as outer layers of food cartons, such as cereals and tea. Bionanocomposites for Food Packaging Applications. The most commonly used material for food packaging is plastic. Conventional food packaging materials currently used vary between metals, paper, glass, and plastics [5]. Table 1: Different categories, types, and applications of biodegradable polymers. Thermosets are polymers that irrevocably solidify upon heat and are non-reformable, which makes them unsuitable for food packaging. In Sustainable Food Systems from Agriculture to Industry.
