F. A. Q.

Access comprehensive information in our dedicated FAQ concerning Glassrock products and services.

Why China offers the best quality price ratio ?

With an unlimited supply of gas, boundless production capacity, and a motivated workforce eager to perform at full capacity, China is positioned as a key player in alleviating the global energy & glass supply demand.

GlassRock offers:

Fast turnaround times with exceptional speed from concept to delivery.
Adherence to strict international standards (ISO 9001 certified), guided by western joint venture partnership
Chinese production & raw material lower costs.
Low minimum order quantities from 12,000 units for glass bottles.
Molds price starting at 1800$.
Sales in over 5 continents worldwide.
Flexibility and responsiveness to customer needs.

China continues to scale up glass production to meet surging global demand, which otherwise risks going unmet.

Why GlassRock rather than a competitors ?

We are able to propose anti scratch coating even on small batches of tailor made bottle , while competition usually requires 100 000 + bottles and 4 molds to propose this service we can offer it with one mold on a 30 000 bottles.

Thanks to our local entity, we are able to handle export tax rebate procedures directly with Chinese customs when goods are shipped abroad. In China, many third-party suppliers are unable or unwilling to manage this process, as VAT refunds can take up to nine months to be returned. As a result, they often increase their prices or compromise on product quality, since they do not qualify for export tax rebates. This not only leads to unnecessary costs but also represents money that could be used more effectively elsewhere in your project or business.

Contrary to 100% of our competitor we have a multicultural team trained to international request which proactively propose problem solving course of action and anticipate the usual challenge face in different country our team speaking Chinese, English, French.

We allow ultra customization, having many client in tropical island we are able to propose solution of storage client by client, humidity proof with plastic layer and palettes.

Can I personalize my bottle ?

It’s possible to have a trademark or logo embossed or debossed on a glass bottle. Glassrock provides this service at no additional cost, incorporating the design into the initial bottle mold. You just need to open a mold with your own logo.

Embossing involves raising the logo or design above the glass surface, while debossing creates a recessed impression in the glass. Both techniques offer a unique and visually appealing way to enhance your bottle’s design, making it stand out on store shelves.

We can aswell provide personalized labels for further customization as well as closures adapted to the bottle you need.

While glass allows for many design possibilities, not all designs are feasible (unlike ceramic bottles, which offer more creative flexibility). We encourage you to share your idea with us, and we’ll confirm whether it can be done on your custom glass bottle.

Here are some examples of existing customization methods :
Frosting can give the surface a soft, matte texture that feels refined, while color spraying allows for unique hues or gradients that express a brand’s personality. For decoration and branding, silk screen printing, hot stamping, and decal application enable vivid, durable graphics or metallic details directly on the glass. More intricate touches like laser engraving allow for precise personalization or limited-edition markings, and fire polishing perfects the finish with a smooth, glossy sheen. Finally, metal accessories can be integrated for added weight and distinction, completing a design that’s both visually striking and true to the brand’s character.

What is the difference between a sample bottle mold and a mass-production bottle mold?

A sample mold for a bespoke glass bottle can be used as an early step in a client’s bottle-development process. It is a cost-effective way to review their design and adjust it before committing to full production. Costing 800$, a sample mold is only good for few sample pieces.

A production mold is produced only once the final design has been confirmed. This is a full set of production molds that are usable for at least 500,000 mass-produced glass bottles.

How many glass bottles fit in a 40HQ container?

It is possible to fit approximately 28,000 standard 700ml glass bottles in a 40HQ (high cube) container assuming that they are packed in cartons on pallets.

For smaller capacity bottles such as beer bottles, that contain often 12 oz (330ml), approximately 66,000 can fit in a 40HQ.

These numbers are only approximation, the number of bottle per container varies between every bottle shape or size, verify the product page for details.

What is the difference between flint and super-flint glass?

Flint glass is a clear, colorless, and cost-effective glass commonly used in manufacturing bottles, jars, and other containers. It is lead-free and known for its good clarity. Super-flint glass, also called extra-flint glass, has a higher silica content, giving it superior clarity and brilliance compared to standard flint glass.

At GlassRock, super-flint bottles are typically heavier with a deeper base measuring 20-30mm. They are the top choice for premium spirit brands producing vodka, cognac, brandy, and whisky. Additionally, they have a lower minimum order quantity (MOQ) than flint bottles.

The primary difference between the two lies in their silica content and manufacturing process. Super-flint glass’s increased silica results in exceptional clarity, making it ideal for high-end spirits, perfumes, and cosmetics. While it is more expensive to produce due to pricier raw materials and a more complex process, its superior quality offers a valuable investment for products requiring premium packaging.

Do we need to clean bottles before filling?

Like all other bottling plants anywhere in the world; some dust, card shavings or other particulates can enter bottles and they should always be cleaned on your production line prior to filling.

How does Glassrock monitor the quality?

We have the following quality tests:

measuring tests (weight, content, dimensions, etc.)
destructive testing (internal pressure, pendulum swing impact, thermal shock, etc.)
100% inline testing by inspection machines (wall thickness, crack testing, impurity testing, etc.)
QC workman will check the goods randomly during the production

Are there lead or other harmful chemicals in bottles from China?

The glass bottles themselves contain no lead or harmful chemicals. GlassRock can have them tested by an independent facility upon request to confirm this. However, the inks used for labels may contain lead and/or chromium to enhance color vibrancy. Since these labels do not come into contact with the food product, regulations do not prohibit their use. If desired, GlassRock can use inks without lead or chromium upon request.

Are you a trading company or a manufacturer ?

We are ISO 9001 certified manufacturer implented in China with an international management.

How are the bottles packed?

Bottles are generally packed either in reusable cardboard boxes with dividers or in bulk on cardboard trays on pallets.

GlassRock provides varying levels of cardboard quality and can custom-print boxes with a client’s corporate or product-specific branding.

Many customers choose this option to reuse the shipping boxes for selling their products. The cost of boxes depends on factors like size, cardboard quality, number of printing colors, and the size of the printed area. Bulk packing helps reduce unit shipping costs by allowing more bottles to be packed in a single container

Why are wine bottles usually green or brown?

These colors help protect the wine from light, which can degrade its flavor and create an unpleasant taste.

How are wine bottles made?

Wine bottles are typically made by blowing molten glass into a mold. The glass is then annealed to strengthen it and prevent it from breaking.

What is the average size of a wine bottle?

Why are most beer bottles brown or green?

The color brown and green being the most common. These colors help protect the beer from light, which can degrade its flavor and create an unpleasant taste. Clear bottles are sometimes used for specialty beers or when the brewer wants to showcase the color of the beer. Beer bottles have been used since the 16th century, but commercial bottling didn’t start until the late 17th century.

Clear glass bottles exposed to sunlight caused beer to turn “skunky” due to a chemical reaction triggered by UV rays. Brown bottles were discovered to shield beer from UV rays.

Green bottles were used during World War II when brown glass was scarce and later became a symbol of status for some breweries.

Blue bottles have been developed to provide a more premium positioning for the breweries.

Modern technology allows clear glass bottles to be coated with UV protectants.

How are beer bottles made?

Types: There are several types of beer bottles, each with its own unique characteristics:

Longneck: This is the most common type of beer bottle, characterized by its tall, slender shape. Longneck bottles are often used for lager and pilsner styles.
Swing-top: These bottles have a hinged lid that swings open and closed, allowing for easy refilling and resealing. Swing-top bottles are popular for craft beers and specialty brews.
Stubby: Stubby bottles are shorter and wider than longneck bottles. They are often used for higher-alcohol content beers or for creating a retro or nostalgic feel.
Growler: Growlers are larger bottles that are typically used for filling beer directly from a brewery tap. They are often made of glass or stainless steel.
