4 Powerful Benefits of Powder Coating Glass Bottles

The application of powder coating glass bottles is an important element for many companies in the design, manufacturing, and retailing phases of their products. Powder coating offers several significant financial, environmental, and even visual advantages over other bottle treatment methods.

The following will discuss some of the key benefits of powder coating glass bottles, as well as common use cases across a wide range of industries.

How Modern Powder Coating BeganPowder Coating Glass Bottles

The first iteration of powder coating as we know it today originated in the 1940’s and 1950’s. Previously, the only way to apply organic polymers to a material’s surface was to spray coat them on, a process which was limited as to its efficiency and effectiveness.

However, in the early 1950’s a German scientist named Erwin Gemmer developed a method of applying thermostatic resins to a substrate by means of a fluid-bed application. Then in the 1960’s, the development of electrostatic application made it much easier to spray on even coats of dry powder across the surface of a workpiece.

To this day, most manufacturers still use this simple and efficient electrostatic powder coating process to treat their products.

Four Benefits of Powder Coating Glass Bottles

What are some of the advantages that powder coating can offer to companies that deal in glass bottles? Here are just a few:

1) ENHANCED UV PROTECTION – Ultraviolet radiation can be harmful both to humans, and to many consumable products. While untreated glass typically blocks UV rays with short wavelengths (known as UVB), it does not offer much protection against long wavelength rays (UVA). However, the application of powder coating glass bottles can block potentially damaging UVA radiation from reaching the product contained within the bottle.

2) INCREASED DURABILITY – Powder coated glass bottles tend to be highly resistant to scratching, peeling, chipping, and other effects of normal wear and tear.

3) IMPROVED ECO-FRIENDLINESS – Other spray-on processes that involve solvent-based wet paint often release volatile organic compounds (VOCs) into the atmosphere. These VOCs can damage the environment by contributing to ozone pollution and can also pose a health risk to humans exposed to them for a significant period of time. In contrast, powder coating releases very few, if any VOCs into the environment, making it the preferred choice for environmentally conscious businesses.

4) WIDER BRANDING CAPABILITIES – Since powder coating is such a versatile technique, companies that want to differentiate their products in a crowded market can utilize this process to create glass bottles that have a very distinctive look and feel. In addition, powder coated glass bottles are able to retain their color and texture for a long time, adding to a high quality experience for the end consumer.

Industries that Profit from Powder Coating Glass Bottles

There are many different industries that frequently utilize powder coating methods to treat their glass bottles, including:

Powder Coated Glass Bottles

FOOD & BEVERAGE –  Exposure to UV radiation can, over time, change the taste and flavor of a premium wine, liquor, food and other beverages. Wine-makers and other companies in the food and beverage industry often use powder coating on their containers to protect their products. Not only does it help define a brand, but powder coating glass bottles also helps give the products inside a longer shelf life.

 

COSMETICS & FRAGRANCES – Many companies in the health and beauty sector use a powder coating process to protect body oils, colognes, and other items from UV damage. It’s crucial to powder coat a glass bottle effectively to meet the exacting standards of the cosmetics and fragrance manufacturers. Powder coating glass bottles can also make these products stand out from the crowd by customizing each bottle with a unique style and design.

NUTRACEUTICALS & CANNABIS – From omega-3 fish oils to herbal remedies, many brands that specialize in natural supplements also use powder coating to treat their glass bottles. By powder coating glass bottles, they are ensuring a long shelf life for their product as well as increased product safety.

Without a doubt, powder coating is an integral manufacturing component for many businesses that package their goods in glass bottles.

5 Proven Reasons to Buy Wholesale Glass Dropper Bottles

Glass dropper bottles, often called Euro Rounds, represent an incredible value. Glass containers come with a surprising variety of customization options, are easily transportable in bulk, and can be very cost-efficient. Let’s dive deeper though; here are 5 things to consider when purchasing glass dropper bottles, and 5 compelling reasons to use glass droppers.

They come in a wide range of sizes

Glass dropper bottles can be tiny, or they can be relatively large. Silver Spur’s glass dropper bottles come in sizes that range from 5ml all the way up to 100 ml, with numerous, incremental sizes in between. Whether you are looking to bottle a small, medicinal product or essential oil to be applied on a drop-by-drop basis, or a larger-quantity medication, there is a bottle size made to fit your needs.

They are a safe storage method

Glass dropper bottles allow you to store all kinds of mixtures, medicines, and chemicals. Glass dropper bottles are primarily used to store and transport items like eye drops, liquid medications, CBD products, essential oils, ear care medications, hair care products, and other hygiene products such as soap or shampoo. Clever up-cyclers all over the world have also found ways to repurpose these versatile, safe bottles to hold just about anything. What makes them so useful though?

Due to the manufacturing processes used to make glass, dropper bottles are inert. That means that the few added materials used in their manufacture will not seep into the bottle’s contents and contaminate them. They are incredibly easy to transport and store, and are a naturally reusable resource that can either be repurposed or recycled regardless of what they contained inside.

They come in a variety of colors

The color of your glass dropper bottle matters. Although color can be used to make a product more attractive, lending increased branding utility to your droppers, color isn’t just for show. Colored bottles, especially amber bottles, help prevent chemical changes from occurring with the bottle by blocking harmful UV light from interacting with the liquid inside.

Silver Spur offers a range of colored bottle options including flint, green, blue, and amber that are ideal for both marketing purposes and to protect the integrity of the contents within.

There is a choice between dropper inserts

Dropper inserts are attachments that are used for administering the contents of the bottle in single-drop increments. Typically, dropper inserts are used with eye drops, ear drops, or hair care products.

There are two types of dropper inserts available: vertical or horizontal. Both give users exceptional control when dispensing the bottle’s contents, with the horizontal dropper insert giving the user a slight advantage, especially when self-administering solutions like eye drops.

There are a wide range of bottle closures available

If you don’t require a dropper insert, there are numerous types of bottle closures available to prevent the contents of the bottle from spilling during transport. They come in two different classifications: dispensing vs non-dispensing.

Dispensing closures feature a pipette that extends down into the bottle. One common type of dispensing closure is the bulb syringe that’s commonly paired with a dropper bottle. Non-dispensing closures do not have a pipette, but otherwise can be very similar. Both types usually come with a child-resistant (CRC) or tamper-evident (TE) mechanism.

The advantage of wholesale

Glass dropper bottles are versatile and convenient. They come with a surprising amount of customization options, and can be employed for a near-infinite number of purposes. The biggest advantage to using glass dropper bottles is that their value increases as you buy them wholesale, without the typical worry of environmental impact.

The History of Boston Round Bottles

The History of Boston Round Bottles

Everybody talks about the discovery of fire and the invention of the wheel as humankind’s greatest achievements. But there’s another achievement that has an ancient history and a transformative effect on our way of life. The humble Boston Round glass bottle.

Bottles are so commonplace now that it’s hard to imagine them not existing. Our dive into the history of the glass Boston Round bottle needs to begin with how bottles came about in the first place.

When you start to think about everyday items in your home and workplace, you’ll find that you might know little about their histories. Objects we take for granted haven’t been around forever. Yet each one makes our lives easier.

If you’re intrigued about the history of glass bottles and the Boston Round bottles, keep reading to see what we’ve uncovered.

A Leap into the History of Glass Bottles

Before glass bottles, our ancestors made water containers from animal hides and gourds.

The first known invention of glass bottles was in ancient Egypt over 3000 years ago. The Egyptians made rudimentary glass bottles at first. They created a paste made from the natural substance silica and coated it in molten glass.

Glass itself was invented two thousand years prior. It wasn’t until glass blowing techniques came about in the 1st century BC that the material was used for many applications.

As glass jars and bottles are durable and useful, they were made in increasing quantities as the centuries passed. Glass bottles were made on a mass scale with the invention of automatic glass blowing technology in the late 19th century.

When Was the Boston Round Glass Bottle Invented?

Whether you recognize the name or not, you’ll recognize the bottle. The Boston Round bottle is commonplace, particularly in drug dispensaries and pharmaceutical companies. In fact, you might well have a few in your bathroom cabinet.

When glass bottles became easier to make in the 19th and 20th centuries, production shot up. They were particularly popular in the medicinal industry as the ideal form of packaging because glass is airtight and keeps odors out (or in). The ability to create dark-colored glass such as amber was also beneficial, as it prevents UV rays from degrading light-sensitive products inside.

Boston Round glass bottles could potentially have been designed to store liquids over solids as they have a narrow neck. This narrow diameter would’ve helped prevent any evaporation around the original cork stopper, something a solid, like a tablet, wouldn’t suffer from.

There are no records to describe when the Boston Round bottle came about. This is possibly because many glass bottle suppliers existed in the late 1800s and 1900s, each offering similar bottles.

Where Did Boston Round Bottles Get Their Name?

When glass bottle manufacturing took off in the pharmaceutical industry, bottles were commonly described by their shape. Bottles containing beverages, particularly carbonated drinks, were often round. This is because a round bottle has much more inherent strength than one of any other shape.

The likelihood is that Boston Round bottles have “round” in the name purely as a shape descriptor.

So why are they named “Boston”?

Strangely enough, they were also referred to as a Winchester bottle, particularly in the UK. Named Winchester Quart bottles, they were commonplace in 1860 at least when the Pharmaceutical Journal Part Two was published. The journal states, “…a Winchester quart bottle, which every druggist has in his store-room…”

It was named Winchester, not for the English city but after a measure at the time called a “Winchester”.

There’s no indication of why Winchester Quart bottles are also known as Boston Round bottles, but they were a common bottle at the turn of the 20th century and manufactured by many glassmakers.

What Are Boston Round Bottles Made From?

Traditional Boston Round bottles were made of glass, often brown-colored glass. This was most likely to protect its content from light. This is why you typically see an amber Boston Round bottle as opposed to a clear glass bottle. You can also choose from a cobalt blue or a green soda lime glass color.

The Boston Round glass bottle type has never gone out of fashion though thanks to its useful shape and these days it can be made out of glass or plastic. Glass is durable, easy to sterilize and 100% recyclable, making it an ideal material for storing a range of medicinal compounds.

Plastic has the benefit of being lightweight and still strong. The Boston Round also features a threaded neck for a screw cap. These became common from 1930 onwards and took over from corks and glass stoppers as the most useful sealing method.

Why Are They So Popular?

Whether you call them Boston Rounds, Winchester Bottles or Winchester Quarts, the bottle shape has seen enduring popularity for over a hundred years. The rounded shoulder is useful for solids and creams as angled shoulders can cause the contents to get stuck. The narrow neck is traditionally beneficial for liquids, preventing evaporation and making it easier to pour accurately. As they’re round, they’re also exceptionally strong and more comfortable to handle.

Of all the glass bottle shapes, it seems that this was the optimal design. You can use them with many different types of tops as well. We’ve even optimized the caps to the bottles to include liquid droppers, lotion pumps, spray tops, as well as the standard screw-on black cap.

These days, you can buy Boston Round bottles in a wide variety of colors. From clear glass to amber, cobalt blue, and green, both colored plastic and glass bottles are available to suit your needs. The amber color can protect your contents from the sun, whereas the clear Boston Round bottles allows for maximum visibility of the contents in your bottle. Clear Boston Round bottles are perfect for liquids that you want to display such as colorful herbal supplements.

Boston Round Bottles Are Popular As Ever

The history of pharmaceutical equipment is fascinating and often overlooked. Boston Round bottles are such a popular shape that we all have instances of them around our homes. These glass bottles have been used for packaging for many years and are tried and true.

Useful for everything from essential oils to medicines to CBD’s and creams, we can’t see the Boston Round falling out of favor.
