Paper cups are considered to be a more environmentally friendly option as compared to disposable plastic cups. Here are some of the key points that make paper cups environmentally friendly 1. Biodegradability: Most paper cups are made from pulp materials, which are usually derived from renewable wood resources, making them biodegradable under natural conditions. In contrast, plastic cups are usually made from petroleum-based materials that do not break down easily. 2. Water Consumption: Plastic cups require a lot of energy, water and chemicals to manufacture. Paper cups, on the other hand, typically consume less energy and water. 3. Energy Consumption: The process of manufacturing paper cups usually consumes less energy as compared to plastic cups. The energy required to manufacture paper cups is mainly used in the production of pulp and the moulding process of the cups, which is relatively low compared to the mining, processing and manufacturing of plastics. 4. Recyclability: Paper cup recycling and recovery facilities are available in some locations. By properly recycling paper cups, the consumption of resources and the generation of waste can be reduced. To sum up, paper cups are environmentally friendly. However, paper cups have a plastic lamination on the inside in order to increase water resistance. Therefore, when choosing paper cups, you can prioritise the purchase of paper cups with biodegradable films to reduce the impact on the environment.

The aqueous barrier coating on coffee cups refers to a type of coating applied to the surface of the cups. It is a water-based coating that is typically used to enhance the appearance and functionality of the cups. The aqueous coating serves several purposes: 1. Enhancing visual appeal: The coating gives the cups a glossy and smooth finish, improving their overall aesthetic appearance. It can make the colors and designs on the cups appear more vibrant and attractive. 2. Providing moisture resistance: Coffee cups are often exposed to moisture from the hot beverage they hold. The aqueous coating acts as a barrier to prevent liquid from soaking into the cup's material, helping to maintain the cup's structural integrity and preventing leakage. 3. Improving durability: The coating adds a layer of protection to the cup, making it more resistant to scratches, scuffs, and general wear and tear. This helps to extend the lifespan of the cup and maintain its visual appeal even after repeated use. 4. Ensuring food safety: Aqueous coatings used for coffee cups are typically formulated to be food-grade and non-toxic. They are designed to be in contact with hot beverages without imparting any harmful chemicals or flavors to the drink. At the same time, water-based coated paper cups are easy to degrade, which is conducive to the protection of the ecological environment and reduce pollution.

Plastic-free coated paper cups are also called barrier coated paper cups. After use, the surface coating will decompose and disappear after treatment. At this time, the paper can be completely recycled.
