When sourcing plastic cups, buyers often decide between PET (Polyethylene Terephthalate) and PP (Polypropylene). While both have their uses, PET is the superior choice for premium cold beverages, while PP is typically used for hot drinks or lower-cost, sealed boba teas. Understanding the difference is key to positioning your brand correctly.
The most visible difference is clarity. PET is crystal clear, offering a glass-like finish. PP, on the other hand, is naturally translucent or hazy. If you are serving a colorful layered drink, a fruit salad, or a visually appealing smoothie, PP will dull the colors and make the product look less appetizing. PET enhances the visual appeal.
Feels firm, rigid, and premium in the hand. It resists deformation when held, providing a high-end experience for the consumer.
Feels softer and more "squishy." While it has high heat resistance (making it microwaveable), this softness can feel cheap for cold drink applications.
PET: Perfect for cold drinks (-20°C to 60°C). Not suitable for hot drinks.
PP: Can handle boiling temperatures (up to 120°C).
Decision Guide: If you are sealing hot soy milk, choose PP. But if you are selling iced coffee, smoothies, or bubble tea where visual appeal and a premium hand-feel are paramount, PET is the undisputed winner.
