That's a great question! For a standard urban kitchen trash bin, typically around 13 gallons, the liner that works best is a durable, leak-resistant plastic bag designed specifically for trash cans.
Here’s the breakdown of what to look for:
* Material & Durability: High-density polyethylene (HDPE) bags are strong and affordable for light daily waste. For heavier or sharper debris (like food packaging or broken glass fragments), low-density polyethylene (LDPE) bags are more stretchy and puncture-resistant. Look for terms like "strong-arm" or "extra strength."
* Fit is Key: The liner should fit snugly. A bag that's too small will slip inside; one too large is wasteful and messy. Standard 13-gallon drawstring bags are the universal fit for most city kitchen bins. Always check your bin's capacity.
* Essential Features: Drawstrings are a must for easy, hygienic tying and carrying. Leak-proof technology (like a star seal at the bottom) is crucial for containing messy liquids from food waste, preventing bin stains and odors.
* Thickness Matters: Gauge (microns) indicates thickness. For general use, 0.7-1.0 mil is standard. For heavier loads, consider 1.2 mil or higher.
* Eco-Conscious Option: If reducing plastic is a priority, consider compostable bags (look for certified ASTM D6400) for food waste, but note they require industrial composting facilities. For dry recycling, sometimes going liner-free or using a reused paper bag is effective.
Pro Tip: Slightly stretch the bag's opening over the bin's rim to create a secure cuff. This prevents it from falling in and keeps the rim clean.
In short, the best liner is a well-fitting, durable, drawstring bag with leak protection that matches your typical waste type. Investing in quality liners saves money and hassle by preventing leaks and tears, keeping your bin cleaner and more sanitary.
