The manufacture of plastic packaging containers for cosmetics is a complex and intricate process involving various materials, technologies, and techniques. As a professional manufacturer of plastic cosmetic bottles, we are committed to providing our clients with high-quality, safe, and reliable plastic packaging containers. Below is an introduction to our manufacturing process:

Material Selection

The materials used for plastic cosmetic packaging containers typically include polypropylene (PP), polyethylene (PE), K-resin, acrylonitrile-styrene (AS), acrylonitrile-butadiene-styrene (ABS), polymethyl methacrylate (PMMA), and polyethylene terephthalate (PET). The choice of these materials directly affects the safety, stability, and environmental friendliness of the products.

PP: Often used to make thicker-walled cream jars, bottle caps, etc.

PE: Commonly used for flexible and somewhat elastic packaging containers.

AS: High transparency and good toughness, frequently used for vacuum bottle bodies.

ABS: Easy to color and used for plated accessories.

PMMA: High transparency but poor chemical resistance, requiring an inner lining for use.

PET: An environmentally friendly material that is lightweight, unbreakable, has high barrier properties, and is resistant to chemicals. It is widely used in blow molding.

Molding Processes

Injection Molding:

Plastic raw materials are heated and softened, then injected into a mold and cooled to form the product.

Suitable for making thicker-walled cream jars, bottle caps, stoppers, etc.

Common materials include PP, PETG, PMMA, ABS, etc.

Blow Molding:

Plastic raw materials are heated and softened, then air is blown into them to expand them, and they are placed in a mold to cool and form the product.

Capable of producing plastic bottles with various structures and shapes, such as lotion bottles and toner bottles.

Common materials include PET, PE, PP, etc.

Extrusion Machine Production:

Plastic raw materials are fed into an extrusion machine, heated, melted, and plasticized, then extruded into a molten parison, which is then placed in a mold and blown to expand and form the product.

Suitable for containers of specific shapes and sizes.

Post-Processing

Removing Excess Material and Burrs:

After molding, the excess material and burrs on the surface of the container need to be removed to achieve a smooth finish.

Assembly:

Caps, nozzles, pumps, and other accessories are installed to ensure tightness and ease of use.

Decorative Treatment:

According to customer requirements, silkscreen printing, gold stamping, labeling, and other decorative treatments are performed to enhance the product's visual appeal and brand recognition.

Silkscreen printing can use regular ink or UV ink, with UV ink providing better results with a glossy and three-dimensional effect.

Quality Inspection

Visual inspections are conducted to ensure that the containers have no obvious defects, scratches, or deformations.

Dimensional measurements are taken to verify the accuracy and consistency of the containers.

Physical and chemical tests are performed to ensure that the containers comply with relevant quality standards and regulatory requirements.

Packaging and Shipment

Packaging:

Appropriate protective materials and packaging methods are used to prevent damage and contamination.

Especially for transparent or translucent bottles with craftsmanship, care must be taken to prevent scratches from mutual collisions.

Shipment:

Packaged plastic containers are shipped according to orders and logistics requirements.

Before shipment, a final quality inspection and verification are conducted to ensure that the product quality and quantity are correct.
