Common Questions
Q: Why choose 4 mil over thinner bags?
A: 4 mil is considered heavy-duty and is ideal when you're storing items with sharp edges (like screws or jewelry findings) or need bags that will be handled repeatedly. Thinner bags (1.5-2 mil) work for lightweight items, but 4 mil won't puncture or tear easily.
Q: Can I use these bags for food items?
A: Yes! These bags are made from FDA food-contact compliant material, so they're safe for storing candy, small baked goods, or any food items. The 4 mil thickness provides extra protection.
Q: What's the best way to seal these bags?
A: You have several options: fold over and tape, staple closed, use a twist tie, or heat seal for a professional finish. Heat sealing creates an airtight closure that's great for long-term storage.
