 One of the first questions that may come to mind when researching Plastic Cosmetic Bottles and cosmetic plastic jar manufacturers is: how are they made?

  The manufacturing process of cosmetic bottles and cosmetic plastic jars begins with either thermoplastic (recyclable) or thermosetting (non-recyclable) resin materials, and can include various methods of molding, including blow molding, extrusion blow molding, lamination, and thermoforming. Products are then quality controlled and inspected to ensure FDA approval or ISO certification. There are also many types of resin materials with various functions, which can be roughly divided into the following types:

  1 PETE or PET (polyethylene terephthalate)

  PET is very popular in cosmetics because of its damage resistance, lightweight, and flexible finish. It can be made transparent, frosted or opaque. It is suitable for most cosmetic formulations and can elegantly display the color and/or consistency of beauty or skincare products.

  PET can be recycled for one use. All PET bottles and cans of NDA also do not contain BPA.

  2 HDPE (High-Density Polyethylene)

  HDPE plastic is durable, reusable, and recyclable. It is suitable for most cosmetic formulations. Although translucent options are available, HDPE cannot achieve a transparent finish like PET.

  3 PVC or V (polyvinyl chloride)

  Although PVC is lightweight and can withstand different temperatures and conditions, it is not easy to recycle. Since toxins and pollutants are released during use and disposal, it can also cause serious health effects.

  4 LDPE (low-density polyethylene)

  LDPE has high flexibility but is not as strong as HDPE, and its resistance to temperature changes is also reduced. However, it has good chemical compatibility, can provide a clearer finish, and is ideal for products that need to withstand squeezing or careful dispensing, such as travel lotions, cosmetics, pharmaceutical products, or medicines.

  LDPE products can be reused, but are difficult to recycle.

  5 PP (polypropylene)

  PP is light, rigid, translucent, and able to withstand temperature changes. In addition to cosmetic containers, PP is also commonly used to make cosmetic lids, bottle caps, and Caska seals (a disc that seals the cream to the container before the top is fixed). PP can be recycled and can generally be reused.

  6 PS (polystyrene)

  Usually used to make foamed polystyrene products, PS applications in cosmetics are mainly used for outer packaging purposes, such as packaging fillers or protective cushioning. PS is easy to break and is designed for one-time use. Recycling can be difficult.

  7 (other)

  This classification involves various resins, such as polycarbonate and acrylate polymers. Therefore, the recycling potential and characteristics vary from type to type.
