PET cold drink cups are made of food-grade material, offering cold resistance, leak-proof safety, and secure handling. Available in various capacities from 330ML to 700ML to meet different beverage needs, they feature an ergonomic arc-shaped body for a comfortable grip. Compliant with international safety standards, they are an ideal choice for milk tea and coffee.
Disposable PET cold drink cups are common packaging containers for beverages such as milk tea and coffee. Their core function is to safely hold cold drinks while preserving taste. Usually made of food-grade PET (Polyethylene Terephthalate), these cups are non-toxic, cold-resistant, and leak-proof, widely used in takeout, convenience stores, and beverage shops. The design must balance sealability, transparency, and grip comfort while complying with food safety standards.
I. Material and Manufacturing Analysis
PET material is widely used in food packaging due to its high transparency and chemical stability. Disposable cold drink cups are integrally formed by injection molding, with a wall thickness typically between 0.3–0.5 mm, ensuring strength while avoiding material waste. Offset printing can be used to print brand logos or patterns on the cup body; the printed layer must pass food contact safety testing. Lid designs include flat lids, high dome lids, and direct-drink lids
II. Specification Selection and Application Scenarios
Common capacities include 330ML, 400ML, 500ML, and 700ML to match different drink sizes. For example, 330ML suits espresso, 500ML fits standard milk tea, and 700ML is used for large fruit tea. In cup design, the viral “chubby cup” increases visual appeal by enlarging diameter, while cold drink cups use an arc-shaped body to optimize grip.
III. Technical Highlights and Safety Standards
Food-grade PET must pass the GB4806.7-2016 national standard test to ensure no harmful substances like BPA. The high-transparency design makes beverage color clearly visible, and the cup body is cold-resistant down to -20℃, suitable for low-temperature drinks like smoothies. The arc-shaped cup bottom disperses pressure, preventing deformation even when fully filled. Production requires a National Industrial Production License (e.g., Yue XK16-204-05893), with daily output up to 10 million pieces to meet large-scale supply needs.
IV. Usage Precautions
Store away from high-temperature environments to prevent cup deformation. For direct-drink lids, ensure the straw hole edge is smooth to avoid lip injury.
