A multi-step process creates durable and high-quality ripple wall paper cups, perfect for hot beverages like coffee and tea. The ripple walls help insulate the mug, keeping the contents warm while also making the mug comfortable to hold. Rippled wall paper cups are made through a multi-step process involving the following steps:
Stock preparation: The paper stock is made by mixing the wood pulp with water and other additives such as starch to make a slurry. This mixture is then pressed and dried to form the cardboard used to make the cups.
Printing: The board is printed with food-safe inks for design and branding.
Die cutting: The cardboard is then cut into circular blanks, each blank will form the body of a cup.
Forming the corrugated wall: The blank is fed into a machine that forms the corrugated wall by wrapping the blank with a layer of corrugated paper. The machine applies heat and pressure to the cardboard to ensure that the corrugated layers adhere to the blank.
Forming the cup: The cardboard is then fed into another machine that folds the cardboard into the shape of a cup with a corrugated outer wall and a smooth inner surface.
Sealed: The bottom of the mug is sealed with a process called rolling seaming, which involves rolling the edges of the cardboard to create a tight seal.
Quality Control: Check the quality of finished cups and remove any defective cups from the production line.
Packaging: The finished cups are packed in sleeves or boxes and shipped to customers.
The ripple wall paper cup is designed for hot beverages like coffee, and its structure provides a degree of heat resistance. The corrugated wall design consists of two layers of cardboard with a corrugated layer in between, creating an insulating air gap that helps keep the contents warm while keeping the outside of the mug cool to the touch.
The heat resistance of corrugated wallpaper cups depends on several factors, including the quality of the cardboard, wall thickness, and cup design. Generally speaking, high-quality corrugated wallpaper cups can provide enough heat resistance for hot drinks such as coffee, allowing users to hold the cup comfortably without burning their hands.
However, it should be noted that the heat resistance of paper cups is limited. If the drink is very hot or the cup is left for too long, the cup will become too hot to hold. Always take care when handling hot beverages and use proper protection such as sleeves or holders to avoid burns or spills.
