The design of disposable plastic straws fully reflects the principles of ergonomics and aims to provide excellent comfort. Its length, diameter and curvature are carefully calculated to meet the drinking habits of different users. For example, straws designed for children are usually shorter and of moderate diameter to facilitate their grip and use; while straws for adults are relatively long so that they can drink easily without tilting the cup. In addition, some straws adopt a unique bending design, which enables users to easily absorb drinks at various angles, significantly improving the convenience of drinking.

In terms of material selection, the design of disposable plastic straws shows a high degree of professionalism. Traditional plastic straws mainly use materials such as polypropylene (PP) and polyethylene (PE), which have excellent toughness and chemical resistance, can effectively resist the erosion of various drinks, and ensure the original flavor and safety of the drinks. In recent years, with the improvement of environmental awareness, biodegradable materials such as polylactic acid (PLA) have gradually been widely used in the production of disposable straws. These materials are not only similar to traditional plastics in physical properties, but can also be degraded by microorganisms in the natural environment, thereby significantly reducing environmental pollution problems.

In terms of functional design, disposable plastic straws also show innovation. In order to meet the needs of different drinks, the design of straws is becoming increasingly diverse. For example, for drinks containing fruit particles or ice cubes, some straws adopt a special aperture design to ensure that the fruit particles and ice cubes can pass smoothly. For drinks that need to be stirred, some straws are equipped with detachable stirring rods to facilitate users to stir. In addition, some straws also introduce a magnetic suction design, so that they can be easily adsorbed on the edge of the cup when not in use, avoiding the inconvenience and health hazards caused by random placement.

In terms of portability and hygiene, the design of disposable plastic straws is also well considered. The design of independent packaging not only keeps the straws clean and hygienic, but also makes them easy to carry and store. Whether dining out or traveling, users can easily carry disposable plastic straws and enjoy delicious drinks at any time. At the same time, this independent packaging design effectively avoids the risk of cross-infection that may occur in public places and ensures the health and safety of users.
