Glass bottle, passing through the moment of luster

Introduction: The main characteristics of glass containers are non-toxic and tasteless; transparent materials, free and changeable shapes, beautiful surfaces, good barrier properties, airtightness, abundant raw materials, affordable prices, and can be used in multiple cycles. And it has the advantages of heat resistance, pressure resistance, and cleaning resistance. It can be sterilized at high temperature or stored at low temperature to ensure that the contents can not deteriorate for a long time. It is precisely because of its many advantages that it is widely used in the daily chemical packaging industry. This article mainly introduces some basic common sense of glass bottles, which can be used for purchasing newcomers.

Getting started and reference, in view of the limited ability of the editor, please leave a message to correct the mistakes, so that we can modify and improve:



In the cosmetics industry, based on raw materials such as quartz sand, limestone, barium sulfate, boric acid, borax, and lead compounds, it is combined with auxiliary materials such as clarifiers, colorants, decolorants, opacifiers, etc., through drawing, blowing, etc. The packaging material products formed by technological processing are called glass containers, also known as glass bottles.



1. Molding process

First, we must design, determine and manufacture the mold. The glass material is made of quartz sand as the main raw material, and other auxiliary materials are melted into liquid at high temperature, and then injected into the mold, cooled, cut, and tempered to form a glass bottle.



2. Surface treatment

The surface of the glass bottle can be treated by spraying, UV electroplating, etc., so that the product is more personalized. The spraying production line of glass bottles generally consists of a spray booth, a hanging chain and an oven. There is also the front-end water treatment for glass bottles, and special attention to the problem of sewage discharge is for glass bottles. As for the spraying quality of the glass bottle, it is related to the water treatment, the surface cleaning of the workpiece, the electrical conductivity of the hook, the size of the air volume, the amount of powder spraying, and the level of the operator.



3. Graphic printing

On the surface of the glass bottle, techniques or methods such as bronzing, high/low temperature ink screen printing, and labeling can be used. .





1. Bottle body

According to the bottle mouth: wide mouth bottle, narrow mouth bottle

According to the color of the material: ordinary white material, high white material, crystal white material, milky white material, tea material, green material, etc.

According to the shape: cylindrical, oval, flat, prismatic, cone, etc.

Common capacity: 5ml, 10ml, 15ml, 20ml, 25ml, 30ml, 50ml, 55ml, 60ml, 75ml, 100ml, 110ml, 120ml, 125ml, 150ml, 200ml



2. Bottle mouth

Common bottle mouth: ?18/400, ?20/400, ?22/400

Conventional (Wide Mouth Bottle): ?33mm, ?38mm, ?43mm, ?48mm, ?63mm, ?70mm, ?83mm, ?89mm, ?100mm

Bottle (control): ?10mm, ?15mm, ?20mm, ?25mm, ?30mm



3. Supporting

Glass bottles are often matched with products such as inner stoppers, large caps or plastic drippers, droppers, anodized aluminum caps, plastic pump heads, anodized aluminum pump heads, bottle cap outer covers, etc. Solid pastes generally use wide-mouth bottles, which are suitable for aluminum or plastic caps, and the caps can be used for color spraying. Emulsion or liquid pastes generally use narrow-mouthed bottles, which should be equipped with pump heads. If the lid is equipped with an inner plug, the small hole for liquid is the same as the inner plug, and the thicker emulsion is equipped with a large hole inner plug.



Glass containers are the second largest category of cosmetic packaging materials.

It can be applied to creams, perfumes, nail polishes, essences, toners, essential oils and other products.

Glass containers are divided into two ends in the cosmetics industry. One is the front-end molding process supplier, and the other is the back-end surface treatment supplier. The front-end focuses on product molding, and the back-end is processed by surface spraying, electroplating, printing, hot stamping and other processes. . Some large glass bottle factories also have their own full-process processing.



There are many sources of glass bottles. In the international market and have entered the Chinese market, there are Pilamo Glass (India), Banoran Glass (Italy), etc., and domestic Huaxing Glass, Huaqi Glass, Samsung Glass, etc. Post-processing products include Yafeng packaging and Meiyi coating.



1. MOQ description:

Due to the characteristics of glass manufacturing (the furnace is not allowed to stop at will), in the case of no stock in stock, the general minimum order quantity requirements range from 30,000 to 100,000, 200,000



2. Manufacturing cycle

At the same time, the manufacturing cycle is long, generally about 30 to 60 days. The larger the order, the more stable the quality of glass. However, glass bottles also have their disadvantages, such as large weight, high transportation and storage costs, and inability to withstand impact.



3. Glass mold fee:

Manual mold is about 2500 yuan, automatic mold is generally about 4000 yuan, 1 out of 4 or 1 out of 8 is about 16,000 yuan-32,000 yuan, depending on the manufacturer's conditions. Essential oil bottles are usually made of brown or colored and colored frosted, which can avoid light. The lid has a safety ring and can be equipped with an inner plug or a dropper. The perfume bottle is usually equipped with an exquisite spray pump head or a plastic cap.



4. Printing instructions:

The bottle body is a transparent bottle, a frosted colored bottle 'White Porcelain Bottle, Essential Oil Bottle' (the color is not commonly used, but the order quantity is high, and the professional line is less used), the spraying effect generally requires an additional 0.5 yuan-1.1 yuan / piece, depending on the area Depending on the difficulty of toning, the silk screen is 0.1 yuan/color. Cylindrical bottles can be used for single color calculation, and special-shaped bottles are calculated for double color or multi-color. There are usually two types of glass bottle screen printing. One is high temperature ink screen printing, which is not easy to decolorize, the color is dull, and the purple color is difficult to achieve the effect. The other is low temperature ink screen printing, which has brighter color and requires ink. High, otherwise it is easy to fall off, and attention should be paid to bottle disinfection. Bronzing silver 0.4 yuan / style. The total number of silk screen and hot stamping should not exceed 2 times. Too much color registration will result in high defective products and high cost.
