Introduction to Bottled and Jarred Packaged Goods
When we walk through the supermarket, we see many bottled and jarred packaged goods on the shelf. Manufacturers use various packaging materials for storing perishable and non-perishable goods. Chemists and pharmacists use Glass vessels and bottles in laboratories to preserve chemicals so they may not react with the environment.
Covering materials have benefits for both producers and consumers. Packed goods are those goods that have a longer shelf life than homemade items. Household items like cleaning chemicals, pet food, meat, seafood, and all commodities come in glass and plastic jars.
Let us explain the history of bottled and jarred packaged goods, the reasons packaging is essential, the function of packaging in logistics, the jarred and packaged goods, and how packaging can extend food shelf life.
History of Bottled and Jarred Packaged Goods
The ancient Egyptians used ceramic jars to store pickles, homemade jam, etc. Glass bottles were first made in Mesopotamia in 1500 BC. Egyptians were the primary producers and users of glass bottles. In ancient times, Manufacturing glass bottles was a steady process. In 1903, Mike Owens invented the glass bottle manufacturing machine, which revolutionized the industry.
After this revolution, the production and use of glass bottles increased. In China, people used mulberry bark containers to store canned foods. NABISCO was the first brand that introduced brand-consumer packing in the 1890s. The packets industry continued to grow, and experts in this industry have introduced many innovations like zinc caps for shoulder seal jars.
Chemists use many chemicals like polypropylene, polyethylene terephthalate, terephthalate, polyethylene, BPA- based polycarbonate, epoxy resins, polyester, polymer, phthalates, etc for packaging. Nowadays every type of packing material is available in the market.
Reasons Packaging is Essential
Safety
Food containers resist the harmful chemicals from transferring into food.
Protection
The primary purpose of packing goods is to protect the products inside the container from any damage while storing, handling and transportation. Packaging protects the commodities from external factors like heat, sunlight, and humidity.
External factors can lead to the spoilage of goods.
Information for consumer
Companies do labeling to list the ingredients and nutrition content on the packet to provide information to the consumer about the health content of the product. Producers label the manufacturing and expiry date on the package.
Usability
Usability refers to plain, uncomplicated, and consumer-friendly packaging. Packing should be user and environmentally friendly.
Attractiveness
Packets are important because of their branding and marketing perspective.
Attractive packing stands out from the shelf and makes a person agree to buy. Wrapping is as necessary as food content. Stunning packets increase sales. A brand’s packets help tell its story. It also assists customers in understanding the brand’s values.
Sustainability
People are getting concerned about their environment because of the increase in air pollution.
Sustainable wrapping materials have more impact on the customers.
Materials Should be effortlessly recyclable and renewable. The packets should have environmental impacts written on their cover.
Impressive packets result in more sales.
Identity
The specific logo design and theme works to recognize the brand.
The Role of packaging in logistics
You need to ensure that your packaging operations are efficient for your brand’s logistics. The supplier must ensure the delivery of goods to the customer in the same condition as when they left the warehouse. Packaging plays a primary role in this process, beginning with selecting materials that can withstand the rigors of transportation.
To prepare products for delivery, it enables you to stack them, place them on pallets, and move them effortlessly throughout the warehouse. Protective wrapping is enough to limit the movement of goods.
Packets contribute to the efficient distribution. Packing also helps in conveying information about critical handling.
Efficient utilization of packets can free up space, reduce costs, and save you valuable time, allowing you to deliver large quantities efficiently.
Types of Bottled and Jarred Packaged Goods
Plastic
Plastic is the most commonly used type of material.
There are many types of plastics used in packaging. Polyethylene terephthalate is the most commonly used material in the US for food and beverage covering. Polyethylene Is a transparent, stiffer, and lightweight type of plastic. Polystyrene is a Nice and light plastic that helps in protecting delicate objects. Producers use silicone polymer for making bottle caps because of its water-resistant and air-tight characteristics. Phthalates (plasticizers) have softening properties. Few countries have legally restricted phthalates for making covers. Packaging should be tamper-evident.
Producers preserve ketchup, jams, and pickles in plastic pails. Manufacturers use Plastic bottles for filling sauces, strawberries, and chocolate syrup.
The tubs of Nutella come in plastic. The bottle of ultramarine blue clothes also comes in plastic. Its moderate rigidity, chemical resistance, high durability, and moisture resistance make HDPE high-density polyethylene bottles a popular choice.
Disposable tumblers, bowls, and egg trays are the formations of polystyrene and polymer.
Drugstore cosmetics such as face wash and lotions come in plastic tubes and dispenser bottles. Water bottles and gallons are a composition of plastic.
Water bottles are reusable, compressible, and recyclable. Food grade, non-toxic and transparent plastic is not harmful. Plastic is the primary material in the production of oil dispensing jugs.
Juice bottles have screw caps, and their primary material is translucent, white plastic. Dishwashers and foamer also come in plastic packing. Empty plastic bottles are recyclable, but they are not environmentally friendly.
Glass
In ancient times, the most commonly used pot was glass canisters. Glass packaging is renewable and recyclable. Fragrances and mists also come in glass sprayer bottles.
Amber, Cobalt-blue, and green glass bottles look attractive and protect their contents from UV rays. Glass bottles with a flip-top and a swing top look unique. Producers use clear glass for Wine bottles, decanters, and carafes. Chemists usually store Expensive creams in Glass cosmetic containers. Glass is the primary material for storing spices. Boston round glass bottles are suitable for storing bath n body products, and chemicals in laboratories. Glass is the core material for making double walls inside Thermos flask bottles. Wide-mouth glass bottles look the trendiest of all bottles. Honey comes in glass bottles, and Skincare items like serums come in Apothecary and dropper bottles.
The process for the formation of glass bottles is blow-molding. Blow molding is joining the parts of plastic and glass bottles.
Metal
Metal is the core material in the production of a sifter bottle.
Cocktails and wax come in a metal tin. Tin-plated steel is a core material in metal containers resistant to corrosion.
They help in the heating and cooling of food contents. Canning is converting metal into a can shape. Beverages and pet food come in cans. Metal containers are durable and reusable.
Producers coat metal packaging on one or both sides (typically cans, containers, caps, and closures).
Inside (food contact) internal coatings such as lacquers or enamels, while outside coatings are external coatings such as enamel, ink, or varnishes. Manufacturers use thermal processing for can coating. The reason for coating is Internal (food contact) coatings:
• protect the contents against the metal – for example, iron pickup in beer or discoloration of dark-colored fruits, such as plums and strawberries, when metals are in contact with them.
• protect the metal can from the contents – for instance, acidic soft drinks (which may corrode uncoated metal) or some fish, meats, and soups (which may cause sulfur stains). The functions of non-food coatings are:
• Protect metals from the environment, e.g. corrosion because of atmospheric pollution;
• Support decoration, labeling, and consumer information;
• Improve mobility (friction) of the article during filling operations. It is only possible to fill beverage cans with an external decoration, which creates friction (mobility) for the can to pass through the head.
We have examined only the internal coatings in this article. Coatings affect the manufacture of the can in the following ways:
• They reduce tool wear on tin-free steel (TFS) substrates. During deformation, electrolytic tinplate (ETP) on the surface of steel “lubricates” the metal, while steel without a tin coating would be very abrasive and the forming presses would rapidly wear out. Practices differ widely across industries, both geographically and company-by-company. There are several examples of (coated) metal packaging normally encountered in this article. Some countries or companies will use a particular type of metal, can, or coating for a specific end-use, while other countries or companies may use other materials for the same end-use. A single can may comprise different metals and several or similar internal coatings.
Types of Metal Cans
There are distinct types of cans and ends (or lids). A can comprises either two or three components (“two-piece cans” and “three-piece cans”); three-piece cans comprise a Cylinder, a top, and a bottom, while two-piece cans have a single top and bottom. Sizes range from tiny (a few grams) to catering packs (2–10 kg).
Drawn cans (two-piece cans) We can find this type of can in the beverage and food industries. Sweets, chocolates, and cookies also come in drawn cans, which usually have a slip lid. We can use both steel and aluminum to pack. Punch can deform metal discs. Companies form two-piece from a blank of metal into a can without a lid. In order to produce drawn cans, Producers use coils of metal that are unwound or stamped metal sheets to convert into discs. The metal substrate is usually double-sided coated. The method differentiates these cans used to form them:
- Single Drawn
- Drawn and Ironed
- Drawn and Redrawn
- Drawn and Wall ironed
Cardboard
Milk bottles/cartons are made of paperboard coated with plastic polyethylene. Paper board is a composition of both hard and softwood.
Cardboard is environmentally friendly and an alternative to the tin plate. Cardboard packaging is lightweight, affordable, and cost-effective.
Wooden packaging
Wooden packaging is a natural type of packaging derived from wood. Wooden pallets are stackable over one another because they can bear weight.
Aluminum packaging
Aluminum is more durable than plastic and glass. Producers use an aluminum wrap for packing Cheese, butter, chocolates, tea, etc.
How can Packaging Extend Food Shelf Life?
It prevents the food from spoilage and contamination.
Barrier
The foil, metalized, or transparent barrier found in packaging protects the product from risks such as oxidation, moisture, and contamination.
Gas permeability:
For products that need air to remain fresh, packaging should have the proper permeability, considering the oxygen transmission rate. Tiny holes may be present in this packaging or use gas-permeable material.
Physical protection
Besides providing physical protection, packaging also helps prevent damage that can make food more susceptible to spoilage risks.
