The application scenarios for lotion bottles cover the entire cosmetic industry chain, including raw material dispensing, finished product packaging, and daily consumer use. Their safety requires multiple verifications: the PETG material must pass FDA or EU EN standard testing to ensure no harmful substances are released; the bottle opening seal must pass pressure testing to prevent leakage during transportation; accessories such as droppers must match the bottle body to avoid jamming or detachment. Furthermore, the abrasion resistance of surface treatment processes must also meet industry standards; for example, the hot stamping layer must pass friction testing to ensure it does not peel off over long-term use.
The mainstream material for lotion bottles is PETG (polyethylene terephthalate-1,4-cyclohexanedimethyl ester), a thermoplastic environmentally friendly plastic with high transparency, strong impact resistance, and chemical corrosion resistance. It also meets food-grade contact standards and is suitable for storing cosmetic concentrates, lotions, and other ingredients.
