Glass bottles are mainly used in cosmetics


Glass bottles are mainly used in cosmetics: skin care products (creams, lotions), perfumes, essential oils, nail polishes have a small capacity, and the capacity of more than 200ml is rarely used in cosmetics. Glass bottles are divided into wide mouth bottles and narrow mouth bottles. Solid pastes are usually wide mouthed bottles. It should be equipped with an aluminum cover or a plastic cover. Caps can be used for color sprays and other effects; lotions or aqueous pastes The body usually uses narrow-necked bottles and should be equipped with a pump head. If the lid is fitted with a stopper, the liquid is provided with a small hole and a stopper, and the thicker emulsion is provided with a large-pore stopper.

1. Cream bottle series: glass bottle body + double plastic cover (general capacity is 10g-50g)

2, the essence of the series: glass bottle + plastic pump head or anodized aluminum pump head (relatively high, 20 to 100ml)

3, toner series: glass bottle + plastic inner plug + shell (100ml or more, can also be equipped with pump head)

4, essential oil bottle series: glass bottle + inner plug + big head cover or glue drop head + dropper + anodized aluminum cover

The hose is divided into a single-layer, two-layer, five-layer hose, which is different from the pressure-resistant penetration and feel, such as a five-layer tube from the outer layer of the inner two adhesive layers and a barrier layer. Features: It has excellent gas barrier properties, can effectively prevent the infiltration of oxygen and odor gas, and prevent the odor of the contents and the leakage of active ingredients.

The hose + cap / hose is usually made of PE plastic. According to the thickness of the product, it is divided into single-layer tube (multi-purpose, low-cost) double-layer tube (good sealing performance). According to the shape of the product, it is divided into a round hose (multi-purpose, low-cost) flat hose, also known as a special-shaped tube (to be a secondary joint, the cost is higher). The outer casing of the hose has a nut (single layer and double layer, the double cover is mostly electroplated cover to increase the product grade, looks more beautiful, the professional line is mostly nut), and the cover.

The material of the plastic bottle is usually PP, PE, K material, AS, ABS, acrylic, PET, etc. Commonly used in cosmetic containers, wall thickness, cream bottle caps, cap gaskets, pump head dust caps for injection molding; PET bottle blowing two-step forming tube blanks for injection molding, blown bottle packaging. Other lotion bottles, such as thinner container wall wash bottles, are blown bottles.

PET-PET has high transparency and the bottle is soft and can be extruded but harder than PP.

PP-PP bottles are softer than PET, easier to squeeze, and less transparent than PET, so some opaque shampoo bottles are more common (easy to squeeze).

PE- bottles are basically opaque and not as smooth as PET. Detailed description of OEM packaging materials, compulsory courses in the cosmetics industry!
