Common questions
What makes 4 mil thickness ideal for industrial applications?
4 mil polyethylene provides optimal balance between durability and cost-efficiency. This thickness resists punctures from sharp tools and hardware while remaining flexible for easy product insertion and sealing. It's the industry standard for heavy-duty protection without excess material waste.
Are these bags compliant with food and pharmaceutical regulations?
Yes. These bags are manufactured to meet FDA and USDA specifications, making them suitable for food storage, pharmaceutical packaging, and other regulated industries. This compliance eliminates additional certification steps and ensures your packaging meets regulatory requirements.
What sealing options work best for these open-top poly bags?
You can seal these bags using twist ties for quick manual closure, bag tape for permanent seals, or impulse sealers for high-volume automation. Impulse sealers offer the fastest throughput for businesses processing large quantities daily.
How many bags do I receive per case, and what's the cost per bag?
Each case contains 250 bags, providing significant volume savings for industrial buyers. Purchasing by the case reduces per-unit costs compared to smaller quantities, making it cost-effective for ongoing packaging operations and inventory management.
