Product Details
A milk tea insulation bag is a portable packaging bag designed to maintain the temperature of beverages such as milk tea. It is widely used in the takeout and carry-out of beverages. Its primary function is to slow down the melting of ice cubes in cold drinks and the cooling of hot drinks, ensuring the beverage maintains its taste for a certain period of time
Suitable for takeout packaging in beverage shops such as milk tea shops and coffee shops, and also suitable for individuals to purchase for takeaway drinks.
Material: The milk tea insulation bag is made of non-woven aluminum foil material
The outer layer is made of non-woven fabric, which is soft, lightweight, and environmentally friendly. It is also easy to print brand logos and patterns, serving as a promotional tool.
The middle layer is made of thermal insulation materials such as pearl wool, which has excellent heat insulation and cushioning properties. It can effectively block heat transfer and also provide a certain level of protection for the beverage, preventing it from being squeezed during transportation.
The inner layer is made of aluminum foil, which boasts excellent thermal insulation and waterproof properties. It can reflect heat, preventing heat loss or heat absorption, while also preventing beverage leakage and ensuring food safety.
