Selection of packaging materials

Common materials for skin care product packaging

"Glass"

Glass: Advantages: Inexpensive/High chemical resistance

Disadvantages: Fragile/Bulky/Requires a large quantity/Low selectivity/few design variations

Used for: various cosmetics, face creams, lotions, essential oil cans, perfumes (with high alcohol content)

Plastic

All kinds of plastics, PE/PP/PETG/PET/Acrylic PMMA/MS/PS/SAN/AS, etc

Other materials

Metal and other aluminum cans/ceramics, etc

Introduction to Plastic packaging materials for skin care prdoucts

Advantages

Plastic has a low density and is light in weight. It can be transparent or opaque. High transparency (combining the transparency of glass).

It is easy to form and process. Just by changing the mold, containers of different varieties can be obtained, and it is easy to form large-scale production.

The packaging effect is good, there are many types of plastic, which are easy to color and have bright colors. Different types of packaging containers can be made according to needs

It has good corrosion resistance, acid and alkali resistance, oil resistance and impact resistance. And it has relatively good mechanical strength.

Disadvantage

Plastic is prone to deformation at high temperatures, so its service temperature is limited

The surface hardness of the container is low, making it prone to wear or scratches

Under the influence of photo-oxygen and thermal oxygen, plastics will undergo aging phenomena such as degradation, brittleness and reduced performance

It has poor electrical conductivity and is prone to static electricity accumulation, etc.

Category

Raw material nature classification mainly includes containers made of polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyester, polycarbonate, etc. 2.

The classification of forming methods mainly includes blow molding, extrusion molding, injection molding, stretch molding, rotational molding, vacuum molding and other types of containers.
