1、 About glass bottles

Glassware products are made of more than ten kinds of raw materials, such as broken glass, soda ash, sodium nitrate, barium carbonate, quartz sand, etc. It is a kind of container made by melting and shaping at 1600 ℃. It can produce glass bottles of different shapes according to different molds, mainly including various wine bottles, beverage bottles, Pickled vegetables bottles, cosmetics bottles and other special-shaped glass bottles,. Glass bottles are sealed and transparent, which can store products that are highly sensitive to humidity for a long time. Its manufacturing process is simple, the shape is free and varied, the hardness is high, it is heat-resistant, clean, easy to clean, and has the characteristics of being reusable. But glass bottles also have their drawbacks, such as heavy weight, high transportation and storage costs, and lack of impact resistance.

2、 Cosmetics glass container

1. Glass bottles used in cosmetics are mainly divided into skin care products (cream, lotion), perfume, essential oil, nail polish and other categories with small capacity, and those with a capacity of more than 200ml are rarely used in cosmetics. Its materials are mainly divided into high whiteness, plain whiteness, sodium calcium, milky whiteness, etc.

2. Glass bottles are divided into wide mouthed bottles and narrow mouthed bottles. For solid paste, wide mouthed bottles are generally used, which should be equipped with aluminum or plastic caps. The caps can be used for color spraying and other effects; Emulsion or aqueous paste generally use narrow mouth bottle, and pump head should be equipped. Attention should be paid to prevent spring and ball from rusting. Most pump heads are equipped with glass beads, and material body test is usually required. If a cover is equipped, an inner plug is required. If a water agent is equipped with a small hole, it is the same as an inner plug, and thicker lotion is equipped with a large hole inner plug.

3. Glass bottles have consistent material selection, multiple shapes, rich processing techniques, and diverse combinations with bottle caps. Common bottle shapes include cylindrical, elliptical, flat, angular, conical, etc. Manufacturers often develop a series of bottle shapes. The bottle body technology includes spray painting, transparent, frosted, semi transparent color matching, silk screen printing, hot stamping, silver stamping, etc.

4. If glass bottles are handmade, there may be some deviation in capacity. When selecting, testing and correct capacity labeling should be carried out. For example, automatic production lines have more uniform requirements, but the shipment volume is larger, the cycle is relatively longer, and the capacity is more stable.

5. Uneven thickness of glass bottles can easily cause damage or be easily crushed by the contents under severe cold conditions. Reasonable capacity should be tested during filling, and paper should be used to hold and separate them individually during transportation. The product should be equipped with a color box, inner tray, and middle box for better anti vibration effect.

6. The commonly used bottle shapes for glass bottles are usually in stock, such as essential oil bottles, ordinary transparent or frosted bottles. The production cycle of glass bottles is relatively long, ranging from 20 days to 45 days for some supplies. The general order quantity is 5000 to 10000, and the smaller the bottle shape, the larger the quantity that needs to be made. The cycle and minimum order quantity will be affected by peak and low seasons.
