Double wall paper cup are a common type of paper drink containers, and the following is a detailed introduction about it:
Structure and material
Double-layer structure: it consists of inner paper cup body and outer paper cup body, and there is usually a certain gap between the two layers to form an air layer, which plays the role of heat insulation and heat preservation.
Material: generally made of food-grade wood pulp paper, the inner and outer layers of paper are bonded together by means of glue or hot pressing. In order to prevent liquid leakage, the inner layer of paper cups is usually treated with a polyethylene (PE) lamination or wax coating.
Features
Good thermal insulation: The air layer in the middle of double-layer paper cups can effectively block heat transfer, reduce the heat of hot drinks to the outside world, prolong the heat preservation time of hot drinks, and at the same time prevent the user's hands from being scalded, so that even when high-temperature beverages are served, the temperature of the hands can still be felt to be relatively low.
Higher strength: Compared with single-layer paper cups, double-layer paper cups use two layers of paper, the paper weight is usually higher, so it is more robust and durable, with better stiffness and compression resistance, not easy to deformation, rupture, and more stable when containing drinks, and can withstand a certain amount of weight and pressure.
Good printing effect: the outer paper layer of double-layer paper cups provides a larger surface area and better printing adaptability, and can be printed with a variety of beautiful patterns, colours and text through the advanced printing process, such as brand logos, advertising slogans, holiday theme patterns, etc., with bright colours and clear realism, enhancing the aesthetics and attractiveness of the product, and playing a good role in publicity and promotion.
Environmental protection and degradable: If biodegradable paper and lamination materials are used, double-layer paper cups can be gradually decomposed in the natural environment, with less pollution to the environment, in line with the concept of environmental protection, which is increasingly favoured by consumers and the market.
