Since the advent of plastic packaging bags, their lightweight, low cost, and high strength have made them widely popular. People have grown accustomed to using plastic bags for carrying items. The market offers a vast array of plastic bag types, with countless variations in color alone—so which kind is truly the best? Do we really make informed choices when selecting plastic bags? Although we use plastic bags almost every day, our decisions about which ones to buy often fall into common misconceptions. (1) The thicker the plastic bag, the sturdier it must be. In daily life, we encounter many different kinds of plastic bags; does that mean the sturdier the bag, the better? Not necessarily. Plastic bags are subject to strict standards, especially those used for food packaging. Only products manufactured by reputable manufacturers and approved by the relevant authorities should be chosen, as only such bags can guarantee quality. Food-grade plastic bags must be clearly labeled “For Food Use.” When held up to the light, you can assess whether the material is clean. Qualified bags are spotless and free of impurities, whereas inferior ones may show stains or foreign matter. The thickness of a single layer of the bag must be at least 0.025 mm; bags thinner than this are prohibited from production and use by national regulations. (2) Colorful plastic bags look attractive—why not choose the most vibrant ones? While plastic bags come in a wide range of colors, caution is essential when making a selection. For bags intended to hold food, it’s best to opt for simpler, more muted hues, as these typically contain fewer additives. Many dark-colored bags are made from recycled waste materials, which are unsuitable for direct contact with food. (3) Reusing plastic bags. Many households keep old plastic bags on hand. In principle, as long as they are stored neatly and used appropriately, reusing them is acceptable. However, never use old plastic bags to come into contact with food or skin, as this can lead to chronic health risks.

Although plastic packaging bags are available in many hues, we must exercise caution when selecting them.
