Common questions
What is the difference between 4 mil and thinner poly bags?
4 mil polyethylene provides significantly greater puncture and tear resistance compared to 2-3 mil alternatives, making it ideal for heavy-duty applications involving tools, hardware, and sharp objects. The added durability reduces product damage during transit and storage, lowering overall cost-per-use despite a higher per-unit price.
Are these bags food-safe and regulatory compliant?
Yes, these bags are manufactured from 100% virgin polyethylene and meet both FDA and USDA specifications, making them suitable for food storage, snack packaging, and other food-contact applications. This dual compliance expands usage across multiple industries beyond industrial packaging.
What closure methods work best with these open-top bags?
Packrift offers three proven closure solutions: Twist Ties for quick, reusable sealing; Bag Tape for secure, closure; and Impulse Sealers for high-speed, airtight sealing in production environments. Choose based on your volume, speed requirements, and reusability needs.
Why choose a 9 x 12" size for industrial packaging?
This mid-range dimension balances versatility and economy, accommodating small to medium parts, tools, and packaged goods while maintaining manageable material costs. The 4 mil thickness at this size offers an optimal strength-to-price ratio for high-volume industrial buyers seeking durability without premium pricing.
