Many procurement personnel do not understand cosmetic OEM packaging materials. They are unclear about the uses and characteristics of glass bottles, tubes, and plastic bottles in cosmetic packaging. Today, I will explain this in detail for you!
1. Glass
Glass bottles are mainly used for cosmetics: skincare products (creams, lotions), perfumes, essential oils, and nail polish, which have small capacities, and capacities above 200ml are rarely used in cosmetics. Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. Solid pastes are usually in wide-mouth bottles. They should be equipped with aluminum or plastic caps. The bottle caps can be used for colored sprays and other effects; lotions or water-based pastes are usually in narrow-mouth bottles and should be equipped with pump heads. If the cap is equipped with an inner plug, the water-based products have small holes and inner plugs, while thicker lotions have large hole plugs.
Combination:
1. Cream bottle series: glass bottle body + double-layer plastic cap (generally with a capacity of 10g-50g)
2. Essence series: glass bottle + plastic pump head or anodized aluminum pump head (relatively high, 20 to 100ml)
3. Powder series: glass bottle + plastic inner plug + outer shell (above 100ml, can also be equipped with a pump head)
4. Essential oil bottle series: glass bottle body + inner plug + large cap or glue dropper + dropper + anodized aluminum cap
2. Tubes
Tubes are divided into single-layer, double-layer, and five-layer tubes, which have different pressure resistance, penetration resistance, and hand feel, such as five-layer tubes having two adhesive layers and a barrier layer from the outer layer to the inner layer. Features: Excellent gas barrier performance, effectively preventing the infiltration of oxygen and odor gases, preventing the leakage of the contents' smell and active ingredients.
Combination:
Tubes + caps / tubes are usually made of PE plastic. They are divided into single-layer tubes (multi-purpose, low cost) and double-layer tubes (good sealing performance) based on product thickness. Based on product shape, they are divided into round tubes (multi-purpose, low cost) and flat tubes, also known as special-shaped tubes (for secondary connections, higher cost). The tube's outer shell has a screw cap (single-layer and double-layer, double caps are mostly electroplated caps to enhance product grade, looking more beautiful, while professional lines are mostly screw caps) and flip caps.
3. Plastic bottles
The materials of plastic bottles are usually PP, PE, K materials, AS, ABS, acrylic, PET, etc. They are commonly used for cosmetic container walls, thick cream bottle caps, bottle stoppers, gaskets, pump heads, and dust caps for injection molding; PET bottles are blow-molded in a two-step process, and tube blanks are used for injection molding, with blow-molded finished products for packaging. Other lotion bottles, such as thinner-walled containers, are blow-molded.
For the above content, you only need to have a preliminary understanding; cosmetic OEM manufacturers have professional staff to explain to you. It is important to remember the differences between the following common materials.
PET - PET has high transparency, and the bottles are flexible and can be squeezed but are harder than PP.
PP - PP bottles are softer than PET, easier to squeeze, and have lower transparency than PET, so some opaque shampoo bottles are more common (easier to squeeze).
PE - The bottles are basically opaque and not as smooth as PET. Detailed description of OEM packaging materials, a must-learn course in the cosmetics industry!
Acrylic - Thick and hard, acrylic is most similar to glass.
