What is the difference of cosmetic packaging jar material?

PET or PETE (Polyethylene Terephthalate )

PET is a lightweight and non-toxic material and can be semi-rigid to rigid. It has excellent humidity and heat resistance properties.

HDPE(High Density Polyethylene)

High Density Polyethylene is a thermoplastic polymer, known for its high strength-to-density ratio. HDPE has little branching, making it stronger intermolecular forces and tensile strength than LDPE.

PP(Polypropylene)

PP is normally tough and flexible. It is a white, mechanically rugged material and has a high chemical resistance.

ABS (Acrylonitrile butadiene styrene)

ABS is impact resistant and tough. A variety of modifications can be made to increase impact resistance, toughness, and heat resistance.

PVC (Polyvinyl Chloride)

PVC is a white, brittle solid. It has strong compressive strength and electrical insulating property.

LDPE(Low Density Polyethylene)

LDPE is defined by low density and it is tasteless, odorless and non-toxic. It has strong humidity resistance and excellent breathability. It cannot withstand high temperature for a long time.

PS (Polystyrene)

Polystyrene is clear, hard, and rather brittle. It is naturally transparent, but can be coloured with colourants.
