About Glass Pacakging
Glass Packaging are made of more than ten kinds of raw materials such as broken glass, soda ash, sodium nitrate, barium carbonate, quartz sand, etc. A container made by 1600 degree high temperature melting and shaping process can be produced according to different molds. The glass bottles mainly include all kinds of special-shaped glass bottles, such as wine bottles, beverage bottles, pickle bottles, cosmetic bottles, etc. The glass bottle has a sealed and light-transmitting product that can be stored for a long time and is highly sensitive to humidity. The manufacturing process is simple, the shape is free and changeable, the hardness is large, it is heat-resistant, clean, easy to clean, and it can be used repeatedly. However, glass bottles also have their shortcomings, such as heavy weight, high transportation and storage costs, and impact resistance.
Cosmetic Glass Packaging
A. Glass bottles used in cosmetics are mainly divided into: skin care products (creams, lotions), perfumes, essential oils, nail polish, several categories of small capacity, more than 200ml capacity is rarely used in cosmetics. Its material is mainly divided into high white material, ordinary white, sodium calcium, milky white material and so on.
B. Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. The solid paste is generally used in wide-mouth bottles. The aluminum cap or plastic cap is suitable for distribution. The cap can be used for color spraying and other effects; emulsion or liquid paste The body is generally used in narrow-mouthed bottles. It is advisable to use a pump head. It is necessary to prevent springs and balls from rusting. Most pump heads are equipped with glass beads, which are usually used for material body test. Equipped with small holes and inner plugs, thicker emulsion is equipped with large holes.
C. The selection of glass bottles is more consistent, with more shapes, rich processing techniques, and a variety of bottle caps. The common bottle shapes are cylindrical, oval, flat, prismatic, and conical. Manufacturers often develop a series of bottle shapes. The bottle body process is sprayed, transparent, frosted, translucent toning, silk screen, bronzing, silver bronzing, etc.
D. If the glass bottle is made by hand, there will be a little deviation in the capacity. When selecting, it should be tested and marked with the correct capacity. However, automatic production line is more uniform, but the shipment volume is relatively large, the cycle is relatively long, and the capacity is relatively stable.
E. The uneven thickness of the glass bottle can easily lead to damage or be squeezed by the contents under severe cold conditions. A reasonable capacity should be tested during filling. Paper should be used for transportation and separated individually. Color box, inner tray and middle box can get anti-vibration effect.
F. The uneven thickness of the glass bottle can easily lead to damage or be squeezed by the contents under severe cold conditions. A reasonable capacity should be tested during filling. Paper should be used for transportation and separated individually. Color box, inner tray and middle box can get anti-vibration effect.
G. The commonly used bottle shapes of glass bottles are usually in stock, such as essential oil bottles, ordinary transparent or frosted bottles. The production cycle of glass bottles is long, and it takes 20 days to be fast. Some delivery periods take 45 days. The general order quantity is 5,000 to 10,000. The smaller the bottle type, the greater the amount to be made. The cycle and the order quantity will be Affected by peak season and low season.
Production Process Of Glass BottlesFirst, the mold must be designed and manufactured. The glass raw material uses quartz sand as the main raw material, and other auxiliary materials are melted into a liquid state at high temperature, and then injected into the mold, cooled, cut, and tempered to form a glass bottle. Glass bottles generally have rigid signs, and the signs are also made of mold shapes. According to the manufacturing method, the molding of glass bottles can be divided into three types: manual blowing, mechanical blowing and extrusion molding.
