Everyone has some level of experience with food packing. Many of the foods we eat today are processed, and packaging technology plays a significant role in ensuring the safety of these foods by preventing spoilage and elongating their shelf life.
If you pay attention, you’ll notice that practically all of the processed items you buy at the shop are sealed in plastic before you bring them home.
The evolution of food packing methods is discussed in this article. Let’s explore the fascinating realm of reliable packaging solutions for food, shall we?
What Exactly Is Food Packaging?
The term “food packing” encompasses the methods, materials, and innovations behind the storage and transport of edible goods.
There are several reasons why foods are packaged, including the ability to keep them for longer periods of time.
However, the technology behind food packaging has not kept up with the times. Its origins are intriguing, to say the least. Such as, many liquid food packaging machines now use quality XHVAL Valves for better flow efficiency.
Who Was The First Who Thought Of Putting Food In Plastic?
There have been many iterations of food packing throughout history. The Journal of Agricultural and Food Chemistry attributes much of its evolution to Napoleon, who reportedly offered 12,000 francs to anyone who could devise a practical food-packaging process. To keep his soldiers fed, Napoleon required a fresh strategy.
According to the Journal of Agricultural and Food Chemistry, Nicholas Appert did not come up with the canning method until 15 years after the original award was given.
Food was boiled and then sealed in airtight glass jars using his method, which eventually led to the development of the canned goods we see in supermarkets today.
A Condensed Overview Of The Evolution Of Food Packing
Packaging for food has a long and storied history. Paper and wrapping paper, used for preserving food, was largely invented by the Chinese.
The Egyptians made advancements in the art of glassblowing and shaping. The versatility of glass allowed it to be shaped into containers for storing liquids and foods.
From there, revolutionary figures like Nicholas Appert pushed things forward. Appert’s ‘canning’ technique using glass was the forerunner to the modern metal can. Quaker Oats, a food producer, began putting their oats in cardboard cereal boxes in the 1880s.
What Are The Main Functions Of Food Packaging?
Putting together food packaging involves a lot more than meets the eye. The primary roles of food packaging include:
- Packaging keeps perishable foods safe from spoilage by isolating them from the air and moisture. Once the food is opened, it quickly spoils. The correct packaging of food results in longer shelf life, which is great news for any producer of said food.
- Food packaging is used to prevent food from spoiling or becoming harmful to eat due to contact with biological agents, such as rats, insects, germs, bacteria, and other such things.
- Everyone reads the nutrition facts label. Brand names, expiration dates, and ingredient lists can all be printed directly on the package of each and every food item for sale.
- Food packaging, such as milk cartons or canned foods with pre-cut slices, also facilitates more convenient product utilization. These foods can be stored for later use according to their respective expiration dates.
How Many Distinct Forms Of Food Packing Are There?
These are some of the wide varieties of food packaging:
- Using aseptic packaging means you’ll get food products that have been disinfected but don’t need to be refrigerated. Food and drink items, including liquid eggs, soup, milk, other dairy products, etc., are packaged in aseptic cartons.
- Meat, seeds, fish, and beverage cans can all be safely stored in trays. They are typically rectangular and flat and have high edges to keep the contents in place.
- Snack foods, including crackers, chips, and packed fruits, are typical candidates for bagging (the process of placing food into bags).
- Cereals, frozen foods, pizzas, fast food, and many other things come in various boxes.
- Beverage and food cans are two common uses for cans, which are durable and multipurpose containers. Their construction utilizes thin metal canisters protected from corrosion by a tin coating.
- In various shapes and sizes, egg cartons for holding eggs, aseptic cartons, and coated paper are the most well-known food cartons.
- Materials like plastic sheets, foil, or paper are used to create flexible packaging. One typical use of flexible packaging is for prepackaged salad in plastic bags.
- The pallet is a sort of non-consumer food packaging that wholesalers and distributors commonly use. A pallet is a flat metal or wooden structure used to transport and store food in several cardboard boxes.
- Wrappers are a product that needs little introduction. Numerous manufacturing techniques are employed for the mass production of sweets, like candy bars and chewing gum, including the widely used flow wrapping.
What Are The Qualities Of Good Food Packaging?
Experts in the field of packaging agree on a few requirements for safe and sanitary food packaging. Some of the top ones are:
After packing is complete, there should be no sign of food spoilage. Hence care must be taken with the packing material and technique.
The packing must be robust enough to withstand the pressures of shipping, loading, and unloading. The quality must meet the packaging used for high-end manufacturers such as auto parts manufacturers and even home appliances manufacturers.
Some food manufacturers skimp on high-quality materials in order to keep prices low. Chemical reactions between these substances and foods can compromise their safety. This means that the packing material must be safe for use with food.
We see food packaging multiple times every day. Unless you happen to be living on a farm, the odds are good that the food you eat has been packaged in some way so that it can be transported more easily.
Because of this, investors should expect a lot from the sector in the coming years. Many upscale packers depend on PWR Pack since they are the go-to provider of innovative food packaging solutions.
