What are the usages and characteristics of cosmetics packaging plastic bottles?


Many purchasers do not understand OEM cosmetics packaging materials. It is unclear the purpose and characteristics of glass bottles, hoses and plastic bottles in cosmetics packaging. Today I will explain to you in detail!


Firstly, Glass bottles


Glass bottles are mainly used for cosmetics packaging: skin care products (creams, lotions), perfumes, essential oils, nail polishes have a small capacity, and the capacity above 200ml is rarely used in cosmetics. Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. The solid paste is usually a wide-mouth bottle. It should be equipped with an aluminum or plastic cover. Caps can be used for color sprays and other effects; lotions or water-based pastes usually use narrow-mouth bottles and should be equipped with a pump head. If the lid is equipped with an inner plug, the liquid agent is equipped with a small hole and an inner plug, and the thicker emulsion is equipped with a larger hole inner plug.


Combination Examples:


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


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


3. Toner series: glass bottle + plastic inner plug + outer shell (more than 100ml, can also be equipped with pump head)


4. Essential oil bottle series: glass bottle + inner plug + big head cap or glue drip head + dropper + anodized aluminum cap


Second, the hose


The hose is divided into a single-layer double-layer five-layer hose, which is different in resistance to pressure, penetration and feel, such as the five-layer tube from the outer layer to the inner two adhesive layers and the barrier layer. Features: With excellent gas barrier properties, it can effectively prevent the infiltration of oxygen and odor gas, and prevent the odor of the contents and the leakage of active ingredients. Actually, it is a nice and popular cosmetics packaging tool today.

 Combination Examples:


Hose + cover / 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 round hose (multi-purpose, low-cost) flat hose, also known as special-shaped tube (to be secondary joint, the cost is higher). The outer shell of the hose has a nut (single layer and double layer, the double cover is mostly an electroplated cover to increase the product grade, it looks more beautiful, and the professional line is mostly a nut), and the cover.



3. Plastic bottles


The material of plastic bottles is usually PP, PE, K materials, AS, ABS, acrylic, PET, etc. Commonly used in cosmetics packaging container wall thickness cream bottle cap bottle stopper gasket pump head dust cover for injection molding; PET bottle blowing two-step molding tube blank is used for injection molding and bottle blowing finished packaging. Other lotion bottles, such as thinner container wall wash bottles are blown bottles.


The above content, you only need to have a preliminary understanding, OEM cosmetic design manufacturer, for examples, XJ Beauty, has professional staff to explain to you. It is important to remember the differences between the following common materials.


PET material: PET bottles has high transparency, the bottle is soft and can be squeezed but harder than PP.


PP material: PP bottles are softer and easier to squeeze than PET, and have lower transparency than PET, so some opaque shampoo bottles are more common (easy to squeeze).


PE material: PE bottles are basically opaque and not as smooth as PET. A detailed description of OEM packaging materials, a required course in the cosmetics industry!


Acrylic material: acrylic bottles are thick and hard. It is most like glass to show you the transparent outstanding feature.
