Transparent plastic vacuum bottle is a kind of vacuum packaging container made of transparent materials (such as PET, PP or AS plastic). Vacuum sealing is achieved through the internal piston or air bag structure to ensure that the contents (such as skin care products, essence liquid, medicine liquid, etc.) are not in contact with the air and prevent oxidation and pollution.
Material characteristics:
PET (Polyethylene terephthalate): High transparency, lightweight, chemical resistant, suitable for water-based or highly fluid products.
PP (polypropylene): semi transparent to transparent, high temperature resistant, steam sterilized, suitable for products that require disinfection.
AS (Acrylonitrile Styrene): High transparency, high hardness, commonly used in high-end skincare packaging.
Structural design:
Using a vacuum pump head and piston/airbag system, air is extracted when pressed to maintain a vacuum state inside the bottle.
The bottle body is transparent, allowing for intuitive observation of the remaining capacity.
