Common questions
Are these bags food-safe and compliant with regulations?
Yes, all bags meet FDA and USDA requirements, making them suitable for food storage, processing, and packaging applications. Compliance documentation is available upon request.
How many times can these bags be resealed?
The durable 4 mil polyethylene and single-track zipper design supports repeated resealing for extended product life. Most users experience 5-10+ reliable closures before showing wear, depending on storage conditions and handling intensity.
What is the difference between 4 mil and thinner gauge bags?
4 mil thickness provides puncture resistance, durability, and moisture barrier compared to thinner 2-3 mil options. This makes them ideal for demanding industrial, food processing, and pharmaceutical applications where product protection justifies the minimal cost premium.
Can I order partial cases or do I need to buy full cases?
Standard ordering is by the case (500 bags per case). For bulk volume needs or custom quantities, contact our sales team to discuss volume pricing and delivery options.
