Glass Oil Bottle Manufacturers

1. Why is glass the first choice for glass oil and vinegar bottles? How does Yangzhou New Coordinate Household Articles Co., Ltd ensure the safety of the material?
Traditional plastic oil bottles are prone to residual grease after long-term use, and may produce carcinogens after oxidation. Glass materials are chemically stable and have no microporous structure, which can prevent penetration and rancidity problems. Yangzhou New Coordinate Household Articles Co., Ltd uses high borosilicate glass (temperature resistance range -40°C to 300°C) and lead-free glass, and ensures safety through the following processes:
● Raw material screening: Only purchase borosilicate sand that meets food grade standards to avoid lead impurities;
● Process control: Accurately control the expansion coefficient during high-temperature firing to prevent cracking during alternating hot and cold;
● Finished product testing: Full inspection of indicators such as light transmittance and impurity bubbles. The permeability of the material can be easily identified by "looking at the color, weighing the weight, and listening to the sound": lead-free glass is lighter and the knocking sound is crisp.

2. How does the bottle mouth design solve the pain point of "hanging oil dripping"? New Coordinate's sealing innovation
The original plastic bottle is difficult to clean due to its narrow mouth, and the residual oil stains accelerate the oxidation of oil. The solutions of Yangzhou New Coordinate Household Articles Co., Ltd include:
● Stainless steel nozzle + glass bottle body combination: refer to international design, the nozzle is embedded with anti-oil guide groove to reduce surface tension;
● Silicone sealing ring double lock freshness: the bottle cap has built-in elastic sealing ring to isolate oxygen from entering and delay the deterioration of acidic liquids such as vinegar and olive oil;
● Wide-caliber bottle body design: support hand reach in for thorough cleaning to avoid sanitary dead corners.

3. Heat and acid resistance: How is laboratory-grade glass used in the kitchen?
Yangzhou New Coordinate Household Articles Co., Ltd draws on laboratory glass technology to enhance the functionality of glass oil and vinegar bottles:
● Borosilicate glass accounts for 81%: the thermal expansion coefficient is extremely low, and it will not burst when taken out of the refrigerator and directly exposed to the stove;
● Anti-corrosion formula: for acidic liquids such as vinegar and lemon juice, zinc and titanium elements are added to the glass to neutralize chemical erosion;
● Tempered reinforcement process: some products are quenched at high temperature twice, and the impact strength is increased by 30%.

4. Why should we avoid ceramic/ordinary glass oil bottles? Quality barriers of New Coordinate
● Ceramic material defects: microporous structure causes slow oil leakage, and the bottle is sticky and difficult to clean;
● Risk of leaded glass: low-priced glass contains 24% lead, and long-term contact with oil may precipitate heavy metals;
● Quality inspection barriers of New Coordinate:
▸ Acid and alkali resistance test for each batch (immersion in acetic acid solution for 48 hours);
▸ Negative pressure test for sealing (maintaining pressure for 30 minutes at -0.08MPa air pressure);
▸ Pass ISO 9000 system certification, and trace production data throughout the process.

5. How do foreign trade-level standards benefit domestic consumers?
As an integrated industrial and trade enterprise that supports foreign trade orders, Yangzhou New Coordinate Household Articles Co., Ltd applies export quality control to domestic products:
● Comply with European and American food contact material standards (such as FDA/EC1935);
● Environmentally friendly technology: kiln waste heat recovery technology reduces energy consumption, and the same source technology certified by Zibo Glass Industry Green Factory;
● Customized service: support sample processing, which can adapt to the capacity and liquid separation requirements of different catering scenarios.

Yangzhou New Coordinate Household Articles Co., Ltd combines laboratory-level glass technology, foreign trade quality control experience and practical kitchen needs to redefine the value of glass oil and vinegar bottles - it is not only a container, but also a food technology carrier that protects health.
