Why Glass Comes in Different Colors

One of the primary benefits of glass packaging is that it’s renewable. This ensures that this packaging material can be recycled repeatedly without compromising on quality.

Be it a sauce jar used by huge brands or a bottle of wine, the glass can be melted and molded into another shape. And that’ll be another brand new packaging!
However, many always question why this material comes in a variety of colors. Is there a distinction in their respective qualities? Do they suggest something else? Do they work best under different temperatures?
Give this piece a read and you’ll find all your answers.

Color Significance

Check out the bottles shelved in a liquor bar next time you visit one. You’ll notice an interesting color classification there. All the beer bottles are packaged in amber glass whereas wine labels come in green glass bottles. Why is that so? 
Beer needs to be protected from damaging sunlight. The amber bottles absorb ultraviolet rays that hit with wavelengths shorter than 450 nanometers. This helps preserve beer for longer.
Compared to amber glass, green glass offers lesser protection from light. This is because wines and juices can tolerate exposure to light to some extent.

However, alcohol, water and other liquid foods can be stored in clear glass because they’re unaffected by light.

Separation and Recycling

The color of glass being used in manufacturing is important for the purposes of packaging. Similarly, it’s also important to classify scrapped glass based on their color. Therefore, color plays an important part in recycling as well.
It’s important to separate glass based on its color because recycling different colors together might leave a tint on clear glass. Single stream recycling programs have already made it challenging to get crystal clear glass because it’s hard to prevent colors from mixing.
This is particularly dangerous because if contaminants don’t melt into the glass stream, they can result in defected packaging products.

Benefits of Glass

One of the primary benefits of using glass for food products like wine, juices, water, beer, alcohol and sauces is that that it’s an inert material. This means that it doesn’t chemically react with the products to contaminate the contents or ruin their flavor.
Glass also offers greater transparency. This reassures buyers that they’re buying the right product for their needs. It also reflects well on the manufacturer who can claim to be transparent up front.
Glass is vertically robust as well so it reduces the risk of breaking while stacking bottles on top of one another during delivery.
If you’re looking for glass containers, Premium Vials has the largest variety for all types of products.
