2025-11-16

With the rapid economic development of China, disposable paper cups have become a daily necessity for bento boxes, and for family travel and portability, they have become essential daily necessities in places such as homes, restaurants, and offices. The versatile design, bright colors, and fearless characteristics have been loved by many people. At present, paper cups sold in the market are generally made of single-layer paper in terms of structural design. Generally, paper cups have low strength and are prone to deformation after being filled with hot water. The insulation effect is not good and they cannot slip.

Double layered paper cup

Single layer paper cup is one of the disposable paper cups, also known as single-sided coated paper. That is to say, the layer inside the paper cup has a smooth PE forest film single-layer cup, which is generally used to hold drinking water and facilitate people's drinking. The single room material is made of food grade pasture paper and food grade PE film.

Double layered paper cups, as the name suggests, refer to paper cups with 2 layers, and the quality of double-layer paper cups is better than single-layer paper cups. The usage time of double-layer paper cups is also longer than that of single-layer paper cups. It can also be used to hold hot beverages, such as hot coffee.

In order to expand the applicability of paper cups, straight walled double-layer paper cups were introduced to the market in 1940. These paper cups are not only easy to carry, but also can hold hot drinks.

In today's paper cup market, various advertising paper cups, disposable paper cups, etc. can be seen everywhere, but sometimes there are situations such as insufficient product quality assurance, non-standard standards, and chaotic prices. Paper cups are an important part of our daily lives, but when faced with a chaotic product market, we often feel lost when purchasing paper cup products. So, what should we pay special attention to when purchasing double-layer paper cup products?

Firstly, certify the QS logo. According to relevant national regulations, food paper packaging containers and other products must include the QS logo before they can be sold. Therefore, it is important to carefully confirm the product description information when purchasing.

Secondly, the packaging is complete. The paper cups sold are sealed in plastic bags. When purchasing, check if the packaging bag is damaged to protect the paper cups from external environmental pollution. At the same time, the enterprise name, address, implementation standards, production date, expiration date, etc. marked on the paper cup should also be marked in detail. If omitted, it is recommended not to purchase.

Thirdly, aesthetics. Any paper cup product may have some decorative patterns or advertising embellishments. When choosing paper cups for drinking water, we should try not to buy products with bright colors and too many patterns. Because paper cup products come into contact with various inks when coloring. If low-quality ink is used for printing, it will pose a threat to the safety of using paper cups.
