Core product advantages

  1. ​​Double sealing technology​
    It uses a combination of spring clips and food-grade silicone rings (thickness 3.5mm), which has been verified by negative pressure testing (-80kPa) to maintain the freshness of food for more than 12 months. The 140mm wide mouth design is suitable for quick storage and access of granular foods such as coffee beans and nuts, and the opening and closing life is up to 5,000 times.
  2. ​​Soda-lime glass material​
    It complies with GB 4806.5-2016 food contact material standards, and the lead migration amount is less than 0.005mg/L. The tank body is 4mm thick, the impact strength is 1.2MPa, and the transportation damage rate is controlled within 0.8% (based on the 2024 quality inspection report of the Zibo factory).
  3. ​​Storage efficiency optimization​
    The cylindrical structure (diameter 140mm×height 230mm) is suitable for standard storage shelves, supports four-layer stacking, and the single pallet loading capacity reaches 432 pieces, which increases the warehouse space utilization rate by 18%.

How Do Airtight Lids Work?

The clamp-top mechanism is designed to create a tight seal, preventing air from entering or exiting. This ensures that food stays fresh longer and avoids contamination. Unlike screw-top lids, clamp-tops are more reliable for maintaining airtight storage.

Why choose our glass bottles?

1. Professional selection plan for glass bottle raw materials

bulk glass bottle Material

The selection of raw materials for glass bottles is not generalized. Depending on the different uses of glass bottles, the choice of raw materials is also different.

Usually, for wine bottles, beer bottles, olive oil bottles, carboys, growlers, jugs and jars, we will choose soda-lime glass or flint glass (some people call it high grade white glass) according to customer requirements. Among them, soda-lime glass is strong and durable while also having the advantages of being economical and affordable, and is widely used in glass bottle manufacturing.

Perfume Bottles and Liquor Bottles & Spirit Bottles mostly use flint glass (aka high grade white glass) or Extra Flint Glass (also called super flint glass, Crystal White Material). Flint glass has better transparency than soda-lime glass, and this material is suitable for most common alcoholic beverages, such as vodka, whiskey, rum, etc. Because flint glass has sufficient transparency, it can well show the color of the liquor. In addition, it has good physical strength and is suitable for mass production. Most everyday liquor bottles are made from this type of glass. Some economical perfume bottles are also made from this material.

Extra Flint Glass has the highest transparency and is almost colorless. Due to its low iron content and high purity, it can show a pure and clear optical effect. Therefore, it is often used in high-end applications, such as high-end spirit bottles, luxury brand perfume bottles, etc.

Pursuing high-end materials without considering the purpose will make your product lose its market competitiveness. Similarly, it is not a wise choice to only pursue cost reduction so that the tonality of the product cannot match the brand temperament. Contact our customer service representatives, they will give you the most suitable product solution for you.
