When purchasing acrylic containers, you need to understand these basic points

Introduction: Acrylic bottles have the characteristics of plastics such as resistance to falling, light weight, easy coloring, easy processing, and low cost, and they also have the characteristics of glass bottles such as beautiful appearance and high-end texture. It allows cosmetics manufacturers to obtain the appearance of glass bottles at the cost of plastic bottles, and also has the advantages of resistance to falling and easy transportation.

Product Definition

Acrylic, also known as PMMA or acrylic, is derived from the English word acrylic (acrylic plastic). Its chemical name is polymethyl methacrylate, which is an important plastic polymer material that was developed earlier. It has good transparency, chemical stability and weather resistance, it is easy to dye, easy to process, and has a beautiful appearance. However, since it cannot come into direct contact with the cosmetics, acrylic bottles usually refer to plastic containers based on PMMA plastic materials, which are formed by injection molding to form a bottle shell or a lid shell, and combined with other PP and AS material liner accessories. We call them acrylic bottles.

Manufacturing Process

1. Molding

The acrylic bottle shells used in the cosmetics industry are generally formed by injection molding, so they are also called injection-molded bottles. Due to their poor chemical resistance, they generally cannot be directly filled with pastes. They need to be equipped with an inner liner to block them. It is not easy to fill them too full to prevent the paste from entering between the inner liner and the acrylic bottle to avoid cracking.

2. Surface treatment

In order to effectively display the contents, acrylic bottles are often made of solid injection color, transparent natural color, and have a sense of translucency. The acrylic bottle wall is often sprayed with color, which can refract light and has a good effect. The surface of the matching bottle cap, pump head and other packaging materials often adopts spraying, vacuum plating, electrochemical aluminum, wire drawing gold and silver, secondary oxidation and other processes to reflect the individuality of the product.

3. Graphic printing

Acrylic bottles and matching caps are often made using processes such as silk screen printing, pad printing, hot gold stamping, hot silver stamping, thermal transfer, and water transfer to print the company's graphic information on the surface of the bottle, bottle cap, or pump head.

Product Structure

1. Bottle type:

By shape: round, square, pentagonal, egg-shaped, spherical, gourd-shaped, etc. By use: lotion bottle, perfume bottle, cream bottle, essence bottle, toner bottle, washing bottle, etc. Regular weight: 10g, 15g, 20g, 25g, 30g, 35g, 40g, 45g Regular capacity: 5ml, 10ml, 15ml, 20ml, 30ml, 50ml, 75ml, 100ml, 150ml, 200ml, 250ml, 300ml

2. Bottle mouth diameter: common bottle mouth diameters are Ø18/410, Ø18/415, Ø20/410, Ø20/415, Ø24/410, Ø28/415, Ø28/410, Ø28/415

3. Bottle body matching: Acrylic bottles are mainly equipped with caps, pump heads, nozzles, etc. Bottle caps and outer covers are mostly made of PP materials, but there are also PS, ABC materials and acrylic materials.

Cosmetic Applications

Acrylic bottles are widely used in the cosmetics industry.

In skin care products, such as cream bottles, lotion bottles, airless bottles, essence bottles, and water bottles, which acrylic material are used.

Procurement Notes

1. Minimum order quantity

The order quantity is generally 3,000 to 10,000 pieces. The color can be customized. Usually it is made of primary frosted and magnetic white, or with pearlescent effect. Although the bottle and the cap are matched with the same masterbatch, sometimes the color is different due to the different materials of the bottle and the cap.

2.The production cycle is relatively moderate, about 15 days. Silk-screen cylindrical bottles are calculated as single-color, flat bottles or special-shaped bottles are calculated as two-color or multi-color. Usually, the first silk-screen screen fee or fixture fee is charged. The unit price of silk-screen printing is generally 0.08 yuan/color to US$ 0.02 /color, the screen is US$ 15 to US$ 29/style, and the fixture is about US$ 8/piece.

3. Mould cost: injection moulds range from US$ 1,143 to US$ 4,286. Stainless steel moulds are more expensive than alloy moulds, but they are more durable. How many moulds can be produced at a time depends on the production demand. If the production volume is large, you can choose a mould with four or six moulds. Customers can decide for themselves.

4. Printing Instructions: The screen printing on the outer shell of acrylic bottle can be done with ordinary ink and UV ink. UV ink has better effect, gloss and three-dimensional sense. The color should be confirmed by making a plate first during production. The screen printing effect on different materials will be different. The processing technology of hot stamping and hot silver is different from the effect of printing gold powder and silver powder. Hard materials and smooth surfaces are more suitable for hot stamping and hot silver. The hot stamping effect of soft surfaces is not good and easy to fall off. The gloss of hot stamping and hot silver is better than that of hot stamping and hot silver. The screen printing film should be negative, the image effect is black, and the background color is transparent. The hot stamping and hot silver process should be positive, the image effect is transparent, and the background color is black. The proportion of text and pattern cannot be too small or too thin, otherwise the printing effect will not be good.
