Common Questions
Q: What makes 4 mil poly bags different from standard bags?
A: At 4 mil, these bags are twice as thick as standard 2 mil poly bags. This extra thickness provides much better puncture resistance, making them ideal for items with sharp edges, points, or rough surfaces that might poke through thinner material.
Q: Can I use these for food items like breadsticks?
A: Yes! These bags are made from FDA food-contact compliant LDPE material. While most food sellers prefer cello bags for their premium clarity, these heavy-duty poly bags work well when you need extra protection for long, fragile baked goods.
Q: How do I seal these bags?
A: These open-end flat bags can be heat sealed, taped, or tied closed. For a professional finish, we recommend using an impulse sealer — the 4 mil thickness seals cleanly with slightly longer heat time.
