Contenitore per cosmetici

Cosmetic containers are often available in plastic bottles, glass bottles, tubes, vacuum bottles, etc.

1、 The material of plastic bottles is usually PP, PE, K material, AS, ABS, acrylic, PET, etc.

2. Usually used for cosmetic containers with thicker walls such as cream jars, bottle caps, stoppers, gaskets, pump heads, and dust covers.

为注塑成型: PET blow molding is a two-step process, pipe preform is injection molded, and the finished packaging is blow molded. Other containers, such as thin-walled lotion bottles and detergent bottles, are also blow molded.

3、PET materials are environmentally friendly materials with high barrier properties, lightweight, shatter-resistant characteristics, chemical resistance, and strong transparency. They can be made into pearlescent, colored, magnetic white, and transparent forms, and are widely used in the packaging of lotion. The bottle mouth is generally standard sizes of 16#, 18#, 22#, and 24#, and can be equipped with a pump head for use.

4. The acrylic material is an injection-molded bottle, with poor chemical resistance, generally cannot be directly filled with paste, requires an inner liner for barrier, filling should not be too full to prevent the paste from entering the space between the inner liner and the acrylic bottle, to avoid cracking. The packaging requirements during transportation are high, as scratches appear particularly obvious. It has high transparency, a thick wall in appearance, but is expensive.

5、AS、ABS: AS transparency is better than ABS, and its toughness is better.

1. Glass bottles used for cosmetics are mainly divided into: skincare products (creams, lotions), perfumes, essential oils, and nail polishes. The capacity is relatively small, and bottles larger than 200ml are rarely used for cosmetics.

2. Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. Solid pastes are generally stored in wide-mouth bottles, which are suitable for aluminum foil or plastic caps. The bottle caps can be used for effects like color spraying; emulsions or water-based pastes are generally stored in narrow-mouth bottles, equipped with pump heads. It is important to prevent springs and balls from rusting. Currently, most pump heads are equipped with glass beads, and material testing is usually required for suitability tests. If a cap is used, it should be paired with an inner plug. Water-based solutions should be paired with a small hole inner plug, while thicker emulsions should be paired with a large hole inner plug.
