2. PP (Polypropylene): The "Portable Responsibility" That is Lightweight and Safe

Core: Lightweight and flexible, lighter than HDPE; resistant to high temperatures (can withstand temperatures around 100℃), not afraid of occasional cleaning with hot water; odor, high safety, meets food-grade standards, and can hold hair care oil, makeup remover oil, and other intimate wash and care products.

3. PET (ethylene Terephthalate): The "Aesthetic Representative" That is Transparent and Beautiful

Core characteristics: High transparency, can clearly see the remaining amount inside bottle; moderate hardness, not easy to deform; resistant to most wash and care product ingredients (such as cleansers, body lotion), but not resistant to strong acids andis (cannot hold high-concentration fruit acid, salicylic acid products).

Application scenarios: Press-type bottles for sensitive skin cleansers, bottles for essential wash and care products —— Transparent bodies allow easy observation of usage, and a clean appearance also meets the "appearance" requirements of the party of refinement.

When purchasing such PE plastic bottlesNote: PE materials are mostly in the form of soft tubes), you can focus on the sealing of the tube mouth and the soft of the tube body to ensure the user experience.
