Common questions
What is the difference between 4 mil and thinner poly bags?
4 mil thickness provides puncture resistance, tear strength, and durability compared to thinner bags (2-3 mil). This makes 4 mil bags ideal for heavy-duty applications, sharp-edged products, and extended storage periods while remaining cost-effective for industrial buyers.
Are these bags food-safe and compliant with regulations?
Yes, these 4 mil flat poly bags meet FDA and USDA specifications, making them suitable for food storage, pharmaceutical packaging, and other regulated applications. Virgin polyethylene material ensures purity and compliance with food contact standards.
How should I seal these open-end flat poly bags?
Packrift offers three convenient sealing options: Twist Ties for quick, reusable closure; Bag Tape for secure, tamper-evident sealing; or Impulse Sealers for high-volume, professional heat-sealing applications. Choose based on your production volume and security requirements.
What is the optimal storage capacity for these 20 x 30" bags?
The 20 x 30" dimensions provide ample capacity for tools, hardware, textiles, and industrial components while remaining easy to handle manually. Storage capacity depends on product density, but these bags work well for items up to 10-15 lbs without stress to the 4 mil material.
