Glass Sauce & Dressing Bottles

The filling temperature of glass bottles is usually limited by the heat resistance of the glass and the structural design of the bottle. Generally speaking, ordinary glass bottles can withstand a filling temperature of about 60°C to 85°C. If the filling temperature is too high, it may cause thermal cracks or breakage of the glass bottle due to excessive temperature difference.

For specific uses, such as bird's nest glass bottles, ketchup bottles or beer bottles, etc., high-temperature filled bottles can withstand high temperatures of 121°C (such as during steam sterilization, and pasteurization), which depends on the design and manufacturing process of the glass, such as thickness increase, material selection and annealing treatment, etc. For high-temperature filling, it is recommended to choose a glass bottle specially designed for high-temperature filling.

If your product requires high-temperature filling, please inform our sales staff before purchase.

We offer labeling services for your needs. At Newray, we can customize self-adhesive stickers and labels for you. Additionally, we have a partnering labeling factory located nearby that specializes in applying self-adhesive stickers to glass bottles and works with us year-round.

If you require customized labels for bottles or lids, we can fulfill that request. Our factory maintains a clean and organized environment, and all workers wear sterile caps to ensure a hygienic labeling process in a workshop with a cleanliness level of 300,000.

Our pricing is reasonable, and we offer preferential rates for larger quantities. By using our services, you can eliminate the hassle of manual labeling and reduce costs, as our charges are significantly lower than those in your own country. This helps you save money, increase your profit margins, and accelerate your sales growth.

Yes, we can. We can provide matching lids for our ketchup bottles.

The lids are made of a variety of materials. We have iron lids, aluminum lids, plastic lids, plastic flip lids with holes, etc. In addition, we can also customize the size and logo of the anti-theft and leak-proof sealing films often used in ketchup or honey bottles and seasoning bottles.

Newray does not produce these lids and sealing films by itself, but cooperates with well-known domestic lid and sealing film manufacturers to supply them. We have cooperated with these factories for decades to ensure quality and delivery time.

Yes, we can match and ship your goods to wherever you want. We provide door-to-door service, and if our freight forwarder can deliver to the address you provide, we will cooperate.

Yes, we can ship in batches. If your warehouse is not big enough to accommodate all the goods at once, we can ship in multiple batches. Usually we provide customers with a one-month rent-free period. If it exceeds this period, you can pay a small fee for us to help you store the goods. This fee is very low and much more cost-effective than renting a warehouse in your own country.

If your product requires high-temperature sterilization during filling, please inform our sales team in advance. We ensure that the glass bottles we produce can withstand sterilization at high temperatures of 121 degrees Celsius during the initial product design phase. Newray will arrange proofing for your product and provide a sample test report that includes detailed physical and chemical performance indicators, such as impact resistance and thermal shock resistance. You can also use these samples for production-filling experiments to ensure there is no risk of breakage.

Additionally, Newray confidently offers a 100% quality assurance guarantee for our products. If you encounter any quality issues with our glass bottles during the filling process, we will provide after-sales service and full compensation. Our professional after-sales team will be available to address any concerns, ensuring your complete satisfaction. We are able to make this promise because we have full confidence in the quality of our products.

First and foremost, the raw materials used in our lid factory are guaranteed to be of high quality and sourced from the top iron printing manufacturers in China.

Additionally, all iron sheets undergo two treatments for rust prevention prior to production.

For products containing highly acidic contents, you have the option to coat the inside of the lid with a full glue layer, which effectively prevents acidic substances from coming into contact with the iron lid. While lids with a full glue coating tend to be more expensive than the standard half-glue option, they provide superior rust prevention.

If your country has strict requirements for BPA-free or plastic-free lids, please inform our sales team, and we will provide you with a quotation for the appropriate products.
