Common questions
Are these bags FDA approved for direct food contact?
Yes, these 4 mil white block reclosable poly bags meet FDA and USDA requirements for food contact applications, making them suitable for food storage, ingredients, and packaged goods destined for retail distribution.
Can I write directly on the white block without pre-labels?
Absolutely. The integrated white write-on block is designed for pen, marker, or label gun application, eliminating the need for separate labeling and reducing your per-unit packaging costs and prep time.
What makes 4 mil thickness different from thinner poly bags?
4 mil LDPE provides puncture resistance, tear strength, and durability compared to 1-3 mil bags. This means fewer damaged shipments, longer shelf life during storage, and reduced waste, critical for industrial and food supply operations.
Are these bags resealable multiple times?
Yes, the reclosable zipper closure is designed for multiple open-and-close cycles without loss of integrity, allowing customers to access contents repeatedly while maintaining freshness and security throughout the product lifecycle.
