Glass bottles are the main container for liquor packaging. The quality of glass bottles is crucial to the production, transportation, and storage of liquor, as well as consumer experience and safety. Inferior glass liquor bottles will also affect the reputation and brand image of liquor brands, distilleries, and glass bottle traders. As one of the high-quality liquor bottle suppliers in China , HUIHE has nearly 20 years of experience in the production and sales of glass spirit bottles. We have the responsibility to introduce relevant content in detail to people who need to understand the quality of spirit bottles.
High-quality liquor glass bottles refer to glass spirit containers made of high-quality raw materials and precision processing techniques. It has high purity, good transparency, excellent physical properties and chemical stability, and can safely store various liquor. Precision processing instruments strictly control parameters such as temperature and time during the production process, making the surface of the product smooth and flat, not easily damaged, and ensuring the high-end quality of spirit bottles.
Appearance quality: A good glass spirit bottle should be neat and smooth in appearance, without damage or cracks. The mouth of the bottle should be round and bright, without burrs, and the overall lines should be smooth and natural, which will not affect the volume of the material inside the bottle and the leak-proof seal. sex.
Light transmittance: A good glass bottle has good light transmittance, without obvious emulsification, turbidity, bubbles, etc. that affect the material quality and clear light transmittance.
Thickness: A good glass bottle has a uniform thickness and no uneven thickness, which will not affect the bearing capacity of the bottle mouth or bottle body.
Physical and chemical properties: Good glass bottles show good characteristics in terms of heat resistance, cold resistance, any corrosion properties, antigenic properties, etc., and are not fragile, easy to corrode, easy to absorb substances, etc.
In terms of materials, some inferior glass spirit bottles contain excessive amounts of heavy metals, such as lead and mercury, which are harmful to human health.
In terms of performance, it is poor in resistance to cold and hot temperature differences, vibration resistance and corrosion resistance, and is fragile during transportation and use.
In terms of appearance, it has poor permeability, rough shape, stiff lines, flaws, and a gritty feel to the touch. Specifically in:
In the manufacturing process of glass spirits bottles, the raw materials used to make the mold will also affect the quality level of the product to a certain extent. If the raw material of the mold is of poor quality and has insufficient density, it will oxidize too quickly after being exposed to high temperatures during the smelting process, causing tiny pits to form on the surface of the mold , which will also cause the surface of the glass bottle to be dull. If the shape of the mold is not manufactured correctly or the installation is not consistent enough, the glass bottle will have defects such as protruding seams or protruding mouth edges. If the mold is damaged, there is dirt on the joint surface, or the top core is lifted too late and before it enters the position, the glass frit has fallen into the preliminary mold, which will cause part of the glass to be pressed or blown out from the gap.
If the temperature of the raw material of the glass bottle is too high during the hot melting process, the temperature of the gob will be too high. The bottle produced after the initial mold has not been completely cooled and formed. At this time, it will cause collapse and deformation. If the glass liquid is Failure to accurately enter the mold, resulting in excessive friction with the surface of the mold, will cause the gob to be overcooled, the gob to be too long , and the gob to not fall in the middle of the prototype mold and stick to the wall of the mold cavity, causing wrinkles and deformation. In addition, the raw materials contained in the glass bottle material are not clean, and the temperature of the material is uneven when it is put into the kiln for hot melting, which will cause bubbles to appear in the produced liquor bottle.
The main reason for the cold storm is that the glass spirits bottle is in the cooling and setting process and fails to reduce the thermal stress caused by the temperature difference of the product. This results in cold storms and cracks. After the hot-melted glass raw material is dropped into the molding mold, the artificial molding blows up and spreads unevenly, which will cause spots to appear on the body of the liquor bottle. The spots on glass spirits bottles are divided into two types: cold spots and spots. The machine's discharging speed is uneven. Improper adjustment of the air nozzle will cause the temperature of the initial mold and the finished mold of the liquor bottle to be inconsistent, which will easily cause cold spots on the body of the liquor bottle. Spots directly affect the smoothness; spots are caused by uneven machine speed or too slow speed, resulting in uneven glass bottles and uneven bottle wall thickness, resulting in spots.
Uneven thickness refers to the uneven distribution of glass on the glass bottle, mainly due to the uneven temperature of the glass droplets . The hot parts have low viscosity and are easy to blow thin; the low-temperature parts have high resistance and are thicker. The temperature of the model is uneven. The glass on the warm side cools slowly and is easily blown thin. The glass on the cold side is blown thick because the glass cools quickly.
The temperature of the gob is too low or the model is too cold, the mouth and shoulders of the spirits bottle will not be fully blown, resulting in defects such as gaps, deflated shoulders , and unclear patterns.
When purchasing glass spirits bottles, you need to make a simple judgment on the quality of the glass spirits bottles. The specific judgment methods are as follows:
Check the spirit bottle material: Check the type and quality of glass used in the bottle. High-quality spirits bottles typically use thick, durable glass that feels sturdy in the hand. Check whether the glass is clear, free of bubbles, impurities or flaws, and whether the surface is smooth, cracked or stained.
Assess the structure of the liquor bottle: Inspect the bottle for obvious flaws, such as cracks, chips or uneven seams, protruding or dented bottoms. Run your fingers along the rim of the bottle to make sure the edges are smooth and well-handled.
Observe the stability of the spirit bottle: Observe whether the glass bottle body is deformed or skewed, and whether the bottle is stable and balanced when placed on a flat surface to ensure that the bottle is upright and not shaking.
Test the tightness of spirit bottles: Depending on the type of closure used (cork, synthetic cork, screw cap , etc.), evaluate its sealing functionality. Open and close the bottle to evaluate its ease of use and effectiveness of the closure mechanism. Pour a small amount of liquid from the bottle and check for leaks or drips.
It's worth noting that some quality aspects of a spirits bottle, such as glass thickness and weight, may vary depending on the bottle's purpose and price point. High-end bottles may have thicker glass and more intricate designs, while more affordable bottles may have thinner glass but still meet quality standards.
By evaluating the appearance of glass spirit bottles, we can roughly check some quality problems of glass bottles. However, for the physical and chemical properties of glass bottles, we need to use instruments to conduct professional tests to detect various defects of glass bottles. Whether the parameter value is within the qualified range. The following is an introduction to professional testing of liquor bottles:
The biggest weakness of glass bottles is their brittleness. During the circulation process of glass spirit bottles, such as production and packaging, spirit filling, transportation and use, collisions between bottles or bottles with other hard objects often occur. Use an impact test instrument to impact the bottle at different locations to measure the material's ability to resist high-speed impact.
Under the general trend of "lightweight" production of glass bottles as a whole, the detection of bottom thickness and wall thickness of glass bottles has also become a necessary inspection item. The minimum thickness of a good glass bottle wall should be more than 1.2 mm, especially for square bottles. Thickness is the most important factor affecting the quality of square spirit glass bottles.
Internal stress is an important physical property that affects the quality of glass. Its presence will reduce the mechanical strength and thermal stability of the glass, so when the internal stress in the product is large or exceeds the allowable value, it may break during transportation, high-temperature sterilization, filling and storage. The inspection of internal stress can control the quality of the product and can also be used to supervise and control the annealing process system.
The infrared inspection machine uses a high-resolution solid-state camera as the imaging data collector, which can quickly image the mouth, body and bottom of the glass bottle passing through the machine. By comparing with the standard model in the computer, it was found that the mouth, body and bottom of the bottle were all damaged or cracked bottles.
Thermal shock resistance is the thermal stability of glass, which refers to the ability of glass to undergo severe temperature changes without being damaged. Expressed as the maximum temperature difference that the glass container can withstand without being damaged. In China's liquor bottle production standards, the standard for glass container liquor bottles requires that the thermal shock resistance of liquor bottles is ≥35°C.
The vertical deviation of a spirit bottle refers to the deviation of the edge of the bottle mouth from the central axis of the bottom of the bottle. That is the roundness value of the bottle. If the bottle deviation is too large, it will affect the operation of the bottle in the production line. For example, the production line is capped by machines. If it is not round, the bottle will not be sealed tightly, resulting in air leakage and deterioration. The verticality of the bottle, while short bottles and bottles with high weight are more likely to have verticality problems.
