When choosing trash bags, many people focus on size and thickness but overlook an important factor: how the bag is folded and sealed at the bottom. The folding style directly impacts strength, leak resistance, and how well the bag fits in a container. Let’s compare the four common types—C-Fold, Star-Seal, Double-Fold, and S-Shape—to see which works best for different needs.
1. C-Fold Liners
C-Fold bags are folded flat in a “C” shape. This makes them compact, easy to stack, and ideal for bulk packaging. However, because the seal is straight across the bottom, liquids may pool and increase the chance of leaks.
-
Best for: Dry waste, offices, and light use.
2. Star-Seal Liners
Star-seal bags are gathered and sealed in a star-like shape. This distributes waste evenly and removes corners where leaks usually occur. They also conform easily to round or square bins.
-
Best for: Restaurants, healthcare facilities, or anywhere leak resistance is critical.
3. Double-Fold Liners
As the name suggests, these bags have a reinforced double fold at the bottom. This design adds extra strength to carry heavy loads without tearing. However, compared to star-seal, they may not fit containers as flexibly.
-
Best for: Industrial use, construction sites, or heavy-duty waste.
4. S-Shape Liners
The S-shape fold improves expansion and bag opening. This design helps liners hold more volume and makes them easier to dispense from a roll. Leak protection is moderate, depending on the thickness.
-
Best for: Retail stores, households, and high-turnover environments where convenience matters.
Which One Should You Choose?
- If leak prevention is your top concern → Star-Seal
- If handling heavy, bulky waste → Double-Fold
- If you need cost-effective liners for dry waste → C-Fold
- If you want easy dispensing and space-saving → S-Shape
