Properties of Aluminum Bottle Closures

Aluminum is the third most common element in the earth’s crust. It is found in nature as stable alumino-silicates. A complex extraction and primary smelting process allows the production of aluminum in its metallic form. Then, when suitably alloyed and with various semi-fabrication processes such as rolling, extruding and forging, a whole spectrum of physical and mechanical properties become available. These properties have led to the extensive use of aluminum in various end markets such as packaging.

Most of the aluminum used in packaging is in the form of rolled cans and glass bottle closures.

The attractive properties of aluminum closures used in packaging industry can be summarized as below:-

Durability and Strength:
Aluminumclosures are durable and strong. You can likely trust aluminum caps to keep your product safe and secure dozens of times a day without even knowing it

The low density and thinner sections of aluminum compared with some competing packaging materials…

Production of Aluminum

The increased adoption of aluminum in the manufacturing industry has created significant economic and environmental wins for both – the business and consumers.

Key Benefits

Green goals achievement
Leading manufacturing companies are using aluminum to achieve their aggressive sustainable manufacturing goals. By building lightweight and artfully designed end products that delight customers the company aims to achieve the green goals.

Positive environmental impact
Aluminum is recyclable. Not only does aluminum production use less energy, but it also reduces landfill waste, contributes much lower greenhouse gas emissions, and reduces costly transportation. A 10 percent increase in aluminum end-of-life recycling rates decreases industry greenhouse gas emissions by 15 percent.

Profit and purpose connection
Customers are increasingly looking to buy from companies with a strong sense of corporate responsibility and a solid environmental track record. As more companies see the link between sustain…

Global Aluminum Market – The Metal That Is In Demand

Aluminum is the most abundant metal found in the earth’s crust. It is available as primary and secondary aluminum for various applications. Primary aluminum is produced from mining ore while secondary aluminum comes from recycled aluminum scrap.

Over the years, aluminum has gained prominence mainly due to its inexpensive extraction process. Moreover, the use of aluminum results in a reduction of CO2 emissions by up to 90% as compared to other products.

Considering these factors, the global aluminum market value is projected to register a good annual growth rate by 2023. In conclusion, the demand for aluminum is expected to increase significantly over the next decade.

These days metal packaging industries are focusing on increasing the production of aluminum caps for glass bottles. As per studies, the global aluminum closures and caps market is growing rapidly and is projected to reach US$68.71 billion in size by 2023 (approx).

Nipra is one of the largest players in the metal pac…

Olive Oil Packaging Tips

Storage and packaging is a very significant step of any food, including olive oil. In fact, olive oil shelf life can be influenced by different factors, from olive quality to processing technologies; however, the selection of proper storage conditions, including packaging, can be of great importance. Hence, the time you start the olive oil packaging process, you must have a thought about the following factors.

Study the products that have already gained shelf space. What makes one stand out from the others?
Check about what kind of packaging is used and why. The answers might surprise you. Often times, it is how attentively the oil is packaged that makes the difference between moving off the shelves and gathering dust on them.
Equally important is that your package protects the product. A clear bottle might show off a pretty harvest-fresh color, but it certainly won’t protect the integrity of the oil from damaging exposure to light. So check what kind of bottle you would want to store th…

How the Demand for Glass Bottle Closures Increase?

A bottle closure is, nothing but a device that seals the contents inside of a bottle, protecting those contents from dust, spilling, evaporation, and/or from the atmosphere itself.

In the olden days there was limited demand for glass bottles and jars since most goods were stored in barrels, pottery jugs, wooden boxes, burlap sacks, etc. Most people also lived off the land and had limited need for glass bottles; they also lacked the resources to pay for such luxuries. Thus, the demand to create variety of closures was limited as cork sufficed for virtually all of the stored products of the time.

The use of bottles - and the need for varied closures to seal them - arose when the market started manufacturing products like liquor, wine, olive oil, patent medicines etc. With the expansion of these demands came the need for suitable containers all of which had to be properly sealed to function. Thus the need for glass bottled goods also increased rapidly. And parallel with the creativ…

Basic Properties of Wine Bottle Closure

To afford the necessary protection, the materials from which the wine bottle closure is to be made must show certain basic properties as listed below:

The material should be impervious to any possible contaminants.
The closure must not absorb foreign substances e.g. absorption of water, dust, germs, etc
The container and the closure should not react together
The closure must be capable of clear labeling, often difficult, for example, with plastics.
The closure/material must protect the wine from light and heat
The container and the closure should not react together, either alone or in the presence of the product. This can occur with a certain combination of dissimilar materials.
Keeping the above properties in mind, aluminum tends to be the best material for wine bottle closure. Aluminum meets the food & health food standards and shows optimal performance in terms of storage and protection. Thanks to the aluminum’s superior barrier qualities - the quality of the wine remains at peak co…

Aluminum Closures for Today’s Wines

Years ago, about 80%-90% (approx) of all wine bottles produced in the world were sealed with natural cork. Today, thanks to aluminum, only 40-50% (approx) of all bottles produced globally are corked. More and more winemakers are shifting their bottle closures to aluminum bottle caps so that it reduces their risk of product spoilage to ensure that their name on a wine bottle stands the test of time as well as their rich heritage.

How did aluminum screw-cap take over corks?

The aluminum screw-cap provides better insulation to the wine from oxygen than cork.
It eliminates the nasty smell that TCA (trichloroanisole) gives out from ‘cork taint’.
Aluminum capped wines contributed more consistency in flavor and taste even when the wine ages, than those bottles, closed with a cork.
The aluminum caps are cost-effective as compared to the corks.
Waste aluminum can be recycled. It saves energy and helps prevent pollution.
Nipra takes pride in offering aluminum bottle caps. The team has extensive kn…
