PET Double Layer Inner Supplement Bottle

PET Double Layer Inner Supplement Bottle with a dual-layer inner liner design, offering an acrylic-like appearance that combines high transparency with excellent structural stability. The dual-layer design effectively enhances sealing and moisture resistance, making it ideal for health supplements requiring strict storage conditions—such as drop pills, capsules, Ganoderma spore oil, bird's nest products, and probiotics. 

These products are widely used by health supplement brands, OEMs, health food enterprises, and cross-border e-commerce businesses.

Capacities range from 12ml to 200ml to accommodate various dosage requirements. The bottle exterior supports multiple finishing techniques—including screen printing, hot stamping, UV printing, frosting, and spray coating—while the inner liner can be customized in various colors to boost brand recognition.  

We provide comprehensive OEM/ODM services covering everything from bottle design and mold development to finished product packaging, offering customization options for capacity, color, logo, and packaging solutions. 

Made from food-grade PET, the products comply with international standards such as FDA, LFGB, and ISO 9001, making them suitable for both domestic and international markets.
