Acrylic bottles combine the advantages of plastics (such as impact resistance, lightweight, easy coloring, easy processing, and low cost) with the aesthetic appeal and high-end feel of glass bottles. They allow cosmetic manufacturers to achieve the appearance of glass bottles at the cost of plastic bottles, while also offering the benefits of impact resistance and ease of transport.
ONE
Acrylic, also known as PMMA or acrylic.
Its chemical name is polymethyl methacrylate (PMMA). It is an important, well-developed, and malleable polymer material with good transparency, chemical stability, weather resistance, easy dyeing, easy processing, and a beautiful appearance. However, because it cannot directly contact cosmetic ingredients, acrylic bottles typically refer to plastic containers made from PMMA plastic as a base, injection molded to form the bottle shell or cap shell, combined with inner liner components made of other materials such as PP or AS.
TWO
1. Molding and Processing
Acrylic bottles used in the cosmetics industry are generally injection molded, hence the name "injection-molded bottles." Due to their poor chemical resistance, they generally cannot be directly filled with creams and require an inner liner for barrier. Filling should not be too full to prevent creams from entering between the inner liner and the acrylic bottle, which could cause cracking.
2. Surface Treatment
To effectively display the contents, acrylic bottles are often injection-molded in solid colors, transparent natural colors, and have a translucent feel. The acrylic bottle walls are often spray-painted to refract light effectively. The surfaces of matching caps, pump heads, and other packaging materials often undergo processes such as spraying, vacuum electroplating, aluminum plating, brushed finish, gold/silver plating, and secondary oxidation to reflect the product's individuality.
3. Graphic Printing
Acrylic bottles and matching caps commonly use processes such as screen printing, pad printing, hot stamping (gold/silver), heat transfer printing, and water transfer printing to print the company's graphic information onto the surface of the bottle body, cap, or pump head.
THREE
1. Bottle Types:
By shape: round, square, pentagonal, egg-shaped, spherical, gourd-shaped, etc. By use: Lotion bottles, perfume bottles, cream bottles, serum bottles, toner bottles,
Washing bottles, etc. Regular weights: 10g, 15g, 20g, 25g, 30g, 35g, 40g, 45g. Regular capacities: 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 accessories:
Acrylic bottles are mainly equipped with caps, pump heads, spray nozzles, etc. Bottle caps are mostly made of PP material, but PS, ABC material and acrylic material are also used.
Screen printing on acrylic bottle shells uses both regular ink and UV ink. UV ink produces a better effect, with gloss and a three-dimensional feel. During production, a sample should be made to confirm the color first, as the screen printing effect will vary depending on the material. Hot stamping (gold or silver) differs from printing with gold or silver powder. Hard materials and smooth surfaces are more suitable for hot stamping; soft surfaces have poor printing results and are prone to peeling. Hot stamping has a better gloss than printing with gold or silver powder.
