What material are milk tea cups made of? In terms of food-contact material regulations, the transparent or translucent milk tea cups commonly used in daily life are predominantly made from food-grade plastics-specifically, polypropylene (PP) or polyethylene (PE). PP material boasts excellent heat resistance (capable of withstanding brief exposure to temperatures exceeding 100°C) and strong chemical stability; it does not readily react with tea, creamers, syrups, or similar ingredients. Furthermore, compliance with the national standard GB 4806.7-2016 for plastic materials intended for food contact is the official basis for designating a product as "food-grade."
Take, for instance, this cup of freshly shaken Taro Mud Boba right here: its walls are thick enough to remain comfortable to the touch-never too hot-and even after vigorous shaking, no condensation forms to obscure the measurement markings. Thanks to its secure lid design, you can toss it into your bag without worrying about leaks; whether tucked into a side pocket during your commute or pulled out later, it remains perfectly clean and dry. The measurement markings are crystal clear-at 30ml, 50ml, 100ml, and so on-making it effortless to precisely mix honey water, dilute sparkling wine, or portion out homemade oat milk. The cup itself possesses a tactile quality that is both flexible and substantial-it is not the flimsy plastic that crumples at a mere squeeze-and even after repeated washing and drying, it remains as transparent and pristine as the day it was new. When baking, it doubles perfectly as a measuring cup; you can simply scoop out a couple of spoonfuls of powdered sugar right before whipping cream, with the measurement lines clearly visible right before your eyes-no need to go rummaging for a kitchen scale. It feels light and nimble in the hand, yet sits firmly and stably on a table; once you've finished your drink, simply twist the lid tight, and it's ready to be refilled with an iced Americano the very next day.
