Glass Bottles And Jars Have Good Chemical Stability And Do Not Pollute The Contents

Glass bottles and jars are packaging containers for food, beverages and many products. They are widely used. Glass is also a kind of packaging material with a long history. With many kinds of packaging materials pouring into the market, glass containers still occupy an important position in beverage packaging, which is inseparable from its packaging characteristics that cannot be replaced by other packaging materials.
It is a hollow glass product that can be sealed with a lid or a stopper and can hold various materials quantitatively. Widely used as packaging containers for beverages, alcohol, chemicals, medicines, stationery and cosmetics. Glass bottles and jars are transparent, easy to clean, good chemical stability, no pollution to the contents, high air tightness, excellent storage performance, rich and colorful shapes and decorations, can be recycled and used many times, and the source of raw materials is abundant. However, glass bottles and jars are easily broken and have a large weight-to-volume ratio. These shortcomings are being gradually improved with the development of process technology.
Glass quality: pure and uniform, without defects such as sandstones, streaks, and bubbles. Colorless glass has high transparency; colored glass has a uniform and stable color and can absorb light energy of a certain wavelength. Physical and chemical properties: It has certain chemical stability and does not interact with the contents. It has certain shock resistance and mechanical strength, can withstand heating and cooling processes such as washing and sterilization, and can withstand filling, storage and transportation, and can remain undamaged when encountering general internal and external stress, vibration and impact. Forming quality: maintain a certain capacity, weight and shape, uniform wall thickness, smooth and flat mouth to ensure convenient filling and good sealing. There are no defects such as distortion, rough surface, unevenness and cracks. Manufacturing process The manufacturing of glass bottles and jars mainly includes batch preparation, melting, molding, annealing, surface treatment and processing, inspection and packaging.
