How to Choose Various Tube and Bottle Styles
Many purchasing staff do not understand skin care OEM packaging products. The main purpose and properties of tubes and plastic bottles in cosmetic boxes are unclear. How to choose?
First, the hose:
( 20mL-50ml Vacuum Pump Adapter Foundation Liquid Tube )
The tube is divided into one-sided two-layer five-layer hose, which is also not the same as the resistance to penetration and touch, such as the five-layer tube from the surface layer to the inner layer of 2 adhesive layers and barrier layers. Features: With excellent gas barrier properties, it can reasonably avoid the penetration of O2 and odorous vapors, and avoid the leakage of the taste of the contents and related ingredients.
Composition:
Tube caps/tube are generally made of PE plastic. According to the thickness of the product, it is divided into single-sided tubes (commonly used, low cost) and two-layer tubes (good sealing properties). According to the appearance of the product, it is divided into annular tubes (commonly used, low cost) and flat tubes are also called special-shaped tubes (to be connected for the second time, the cost is higher). The casing of the hose has a screw cap (single-sided and two-layer, most of the double covers are electroplating process covers to improve the product level and look better, and technical professional lines often see screw caps) and a flip cover.
Second, Plastic bottles:
The materials of plastic bottles are generally PP, PE, K raw materials, AS, ABS, acrylic sheet, PET, etc. Commonly used in skin care products, utensils, fresh cream bottles, corks, caps, gaskets, pump head sealing caps for injection molding process; PET bottle blowing two-step forming tube materials for injection molding process, and packaging of finished products. Other moisturizing lotion bottles, such as thinner wall wash bottles, are blow-moulded.
You only have to have a basic grasp of the above content, and the OEM manufacturers of skin care products have technical and professional staff to express to you.
The key is to keep in mind the differences among the following common raw materials.
PET-PET has high definition, water bottle holder has flexibility, can be extruded but is harder than PP.
PP-PP bottles are softer than PET, easier to extrude, and less clear than PET, so some shampoo bottles that are not fully transparent are more common (favorable for extrusion).
Most of PE-Aquarius are not fully transparent and not as smooth as PET.
