Disposable plastic straws are an indispensable product in modern beverage consumption. They are mainly made of thermoplastics such as polypropylene (PP) and polyethylene (PE). These materials are widely used in the production of straws due to their superior physical and chemical properties. Polypropylene and polyethylene have excellent processing properties and plasticity, which makes the molding operation in the production process simple, so that straws with various shapes and precise sizes can be manufactured. At the same time, the high strength and good toughness of these materials ensure the durability of the straws during use, significantly extending their service life.

In terms of chemical stability, polypropylene and polyethylene perform well and can resist the erosion of a variety of beverages. These materials will not react chemically when exposed to acidic, alkaline or sugary drinks, thereby effectively retaining the original flavor and safety of the beverage. This feature makes disposable plastic straws an ideal choice for various beverage stores, fast food restaurants and family gatherings. In addition, these materials have a certain temperature resistance, can maintain a stable shape in high or low temperature environments, are not easy to deform or break, and are suitable for the needs of cold and hot drinks.

In terms of material selection, disposable plastic straws also take into account cost-effectiveness and environmental protection factors. The abundance of raw materials such as polypropylene and polyethylene and their moderate prices make the production cost of straws relatively low, thereby reducing the operating costs of the catering industry and providing consumers with an affordable choice. However, with the improvement of environmental awareness, the environmental impact of traditional disposable plastic straws has gradually received attention. To meet this challenge, some manufacturers have begun to explore the application of biodegradable materials such as polylactic acid (PLA). These biodegradable materials can be decomposed by microorganisms in the natural environment, significantly reducing the burden on the ecological environment. Although the cost of biodegradable materials is relatively high, their environmental advantages make them the future development trend of disposable straw manufacturing.

In practical applications, disposable plastic straws show remarkable convenience with their excellent performance. Its design allows consumers to drink easily without tilting the cup, greatly improving the drinking experience. At the same time, these straws are easy to carry and store, suitable for use when dining out or at family gatherings, and can meet the needs of consumers at any time. In addition, the design of independent packaging ensures the cleanliness and hygiene of the straws, avoids the risk of cross-contamination, and further improves hygiene safety. Good sealing performance also effectively prevents spillage and leakage of beverages, keeping the environment clean.
