What Are the Types of Food Packaging Materials
Food packaging materials play an important role in assuring that the contents are safe and healthy to consume. This is the reason why food packaging materials have always been a subject of ongoing research. This article will take a look into the different types of food packaging along how a majority of food manufacturers are creating innovative pouring packages for different kinds of beverages.
Glass is a popular choice as a food packaging material and offers a number of benefits as a package material. Since glass packaging is impermeable and non-porous, this ensures that there is no interaction between the food and the glass packaging that may affect the flavor of the beverage or food. Similarly, the zero rate chemical interaction of glass containers also makes sure that the flavor, aroma and the strength of the food content remains unaffected. The small glass jars are more visually pleasing as compared to other packaging and are also environmental friendly as 80% of the glass containers are recycled into new glass packaging. These help safeguard the food contents from being leaked or prone to harmful bacteria. It also helps protect food and drinks from being overly exposed to oxygen and moisture ensuring optimum flavor and freshness.
Plastic is another popular choice as a food packaging material since these are light-weight and convenient as compared to glass packaging. Furthermore, a variety of plastic types are available as food packaging materials. These include poly carbonate (PC), polystyrene (PS), polyvinyl chloride (PVC), polyethylene terephthalate (PET), high density polyethylene (HDPE) and polyethylene (PE). Lately, the hdpe canisters have also gained popularity owing to their flexibility and water resistance, light-weight and insulating. Furthermore, plastic also boosts an outstanding environmental and chemical stress crack resistance.
Metals are also used for food packaging and storage and provide total protection of food. Metal food packaging is also regarded as tamperproof.
However, a number of innovative ways have introduced to manage the outflow of food from the packaging and to eliminate food spilling and dripping. This also includes the flip-top cap since it is effective and clean in controlling the food flow. Moreover, it is also especially suitable for dispensing the higher viscosity products like specialty milks and creamers along with seasonings, spices and condiments. Another similar innovation is the tottle bottles that stand on their cap. These products, of late have become a popular choice in the food industry. These owing to their design have ruled out the contamination and environmental exposure concerns that are associated with opening the jar. The small opening ensures limited exposure to the skin and therefore, rules out the risk that any bacteria or dirt from the fingers or spoon will make its way to the food content.These are the popular food packaging materials and pouring technologies that have changed the way we package, store, preserve, carry and pour our food.
