Why is glass packaging widely used in liquor industries?

February 15, 2023

Although glass packaging is not as common as plastic food packaging, it is still widely used in everyday life. The following article details more information on how packaging suppliers are working to limit the amount of glass in landfills.


Plastic and aluminum are the most common types of food packaging used today. As the popularity of plastic food packaging has skyrocketed, combined with the fact that it is cheaper and increasingly popular, glass is not used nearly as much as it once was. After all, glass can break and can be dangerous when broken or shattered. Plastic is more convenient for many businesses, and consumers agree. Nevertheless, glass continues to be used in a variety of bottles and jars.


In 2002, Australia recycled about 320,000 tons of glass bottles and jars. This equates to nearly 1.2 billion bottles. If they are not recycled, they end up in landfills, exacerbating the country's and the world's environmental problems. Glass recycling is good for the environment, which is one of the main reasons for selling this form of packaging.


For years, glass packaging manufacturers have been refining their manufacturing techniques to produce lighter products. As a result, less material is needed and less waste is generated. A typical stubby beer bottle in 1986 weighed 260 g. In 1997, a stubby beer bottle of the same size weighed only 180 g. This is a 31% reduction. That's a 31 percent reduction. When combined with recycling efforts, far less waste goes into Australian landfills today - and much of that is due to the efforts of packaging suppliers across the country. As more and more consumers take responsibility for their actions, the trend toward glass use will only continue to grow.


First, glass retains natural flavors and qualities


Due to oxidation and hydrolytic rancidity, products should be packaged in containers to prevent them from coming into contact with air and water vapor or moisture, which can lead to premature degradation and unwanted flavors and odors in the product.


If this process occurs in a metal container, rancidity can be catalyzed, making the problem worse. Glass jars are the only material that does not have these problems. These glass jars also have gas-tight metal lids and gas barriers to protect them from the chemical reactions mentioned above.


Second, glass is non-reactive and inert


Glass is made entirely from natural resources, such as sand, silica, soda ash, limestone and alumina. These components make it inert and non-reactive, ensuring that packaged products do not react with glass in any way, and therefore, there are no safety hazards associated with packaging food in glass.


For example, if metal containers are not properly coated, they can rust quickly, which can affect the product and shorten its shelf life.


Plastic bags and bottles, especially when heated to high temperatures, may leach into the product and endanger the consumer's health. Therefore, using glass bottles and jars can keep products safe and tasty for a longer period of time.


In addition, glass can provide a high-end appearance to the product


In terms of appearance and appeal, there is no comparison between plastic, metal and glass jars. Packaging a product in a glass jar makes it look upscale and elegant, and more textured to the touch, greatly increasing the chances of sales, as people tend to choose products that look good and have a good visual experience, and a good look can make the item stand out. It also gives people a feeling that if the product packaging looks good, then the product must also be good. Glass packaging is usually more expensive than plastic and faces a more advanced user group.


In addition, the transparency of glass allows for a visible display of the product, assuring consumers that everything is in order. While the original label will ultimately speak to your business, using cheaper packaging materials can make your brand appear bland and uninspiring. Therefore, it is critical to choose packaging materials such as glass bottles that fit this criteria very well.


Finally, glass can also extend the shelf life of your products


Because glass is a good conductor of heat, it may dissipate or dissipate heat more quickly than plastic bags or jars.


Thus, when temperatures rise above 21 degrees Celsius during transport or storage, glass appears to be more viable because it absorbs heat more quickly. This is also conceivable for metal containers, but as mentioned earlier, there are various drawbacks. Even with sudden temperature changes, the product in the glass bottle stays the same.
