Common questions
Can I write directly on the white block?
Yes. The large white block panel is specifically designed for direct marking with markers, pen, or label makers, eliminating the need for separate labels and reducing labor time.
Are these bags food-safe?
Absolutely. All bags meet FDA and USDA requirements for direct food contact, making them suitable for food storage, distribution, and retail applications.
How durable is the 4 mil thickness?
4 mil LDPE offers excellent puncture and tear resistance for industrial use. It provides durability compared to standard 2-3 mil bags while remaining cost-effective for high-volume operations.
Can these bags be resealed multiple times?
Yes. The reclosable zipper closure maintains structural integrity through multiple open/close cycles, enabling cost savings through reuse across inventory cycles and shipping returns.
