Common Questions
Q: What makes 4 mil bags different from standard poly bags?
A: At 4 mil thick, these bags are about 2-3 times thicker than standard poly bags (typically 1-1.5 mil). This extra thickness provides much better puncture resistance and durability — ideal for sharp edges, heavy items, or long-term storage where you need bags that won't tear.
Q: Can I heat seal these bags?
A: Yes! LDPE poly bags heat seal easily with a standard impulse sealer. The 4 mil thickness may require slightly longer seal times than thinner bags. You can also close them with twist ties, tape, or bag clips.
Q: Are these food safe for packaging baked goods or candy?
A: Absolutely. These bags are made from FDA food-contact compliant virgin LDPE resin, making them safe for direct food contact. Great for packaging breadsticks, pretzel rods, candy sticks, or any long food items.
