That's an excellent question! Finding the right liner for a rectangular trash can can be surprisingly tricky, but getting it right makes cleanup so much easier. The best liner is one that fits well, is durable, and suits your specific needs.
First and foremost, focus on the fit. A liner that is too small will slip down into the can, and one that is too large is wasteful and messy. For a rectangular can, you need a bag designed for that shape. Look for terms like "rectangular," "boxy," or "tall kitchen" bags. To find the perfect size, measure your can's dimensions: height, width, and length. The bag's gallon capacity should match or slightly exceed your can's volume. A snug fit around the top rim is ideal.
Next, consider the material and strength. For general kitchen use, high-density polyethylene (HDPE) bags are strong and affordable. For heavier wet waste, like food scraps, low-density polyethylene (LDPE) bags are more stretchy and puncture-resistant. Always check the micron thickness; a 1.0 to 1.2-mil thickness is a good standard for household use. If you dispose of sharp objects like broken glass or pet waste, opt for a heavy-duty or contractor-grade bag with a higher mil rating.
Finally, think about functionality. Drawstring bags are incredibly convenient for quick and hygienic tying. Scented bags can help neutralize odors in a kitchen, while unscented are better for offices or sensitive noses. For the most eco-friendly option, look for certified compostable bags made from materials like cornstarch, but ensure your local facility accepts them.
In short, the best liner for your rectangular urban trash can is a correctly sized, durable bag that matches your waste type. A well-fitting, strong bag prevents leaks, makes taking out the trash simple, and keeps your can clean.
