Bubble Tea Cups, literally translated as "pearl milk tea cups", are containers specifically designed for holding pearl milk tea. Here is a basic description of them:
- Plastic materials: They are the most common ones. Food-grade plastics such as PP (polypropylene) and PET (polyethylene terephthalate) are often used. The PP material is heat-resistant and has stable chemical properties, making it suitable for holding hot drinks. It can withstand the relatively high temperature of freshly made pearl milk tea without deforming easily or releasing harmful substances. The PET material has good transparency, is lightweight, and has a relatively low cost. It is used to display the rich colors and ingredients of milk tea to attract consumers' attention and is often used for packaging cold drinks.
- Paper materials: They have outstanding environmental protection attributes. The surface is usually covered with a layer of food-grade waterproof film, which can not only isolate the moisture of milk tea and prevent leakage but also conform to the current trend of environmentally friendly consumption. Many coffee shops and tea shops' co-branded pearl milk tea products will choose beautifully designed paper cups printed with characteristic patterns, adding a literary flavor and collectible value.
- Degradable materials: With the concept of environmental protection deeply rooted in people's hearts, milk tea cups made of degradable materials such as PLA (polylactic acid) are becoming more and more popular. They are made from renewable plant resources and can decompose relatively quickly in the natural environment after being discarded, reducing the pressure on landfill and incineration and helping to maintain ecological balance.
- Sealing and leakage prevention: The cup lid fits tightly with the cup body and has a built-in silicone sealing ring to prevent milk tea from spilling when bumped. High-quality cup lids are easy to open and close tightly, ensuring that consumers can carry and drink safely and conveniently.
- Heat insulation and temperature preservation/cooling: The design of double-layer cup walls has become popular. A vacuum or heat-insulating materials are filled in the middle to slow down heat conduction, keeping hot drinks warm for a longer time and cold drinks cold, maintaining the taste. Some cups are also equipped with cup sleeves to improve the comfort of holding and strengthen the heat insulation effect.
