Protect small parts, jewelry components, and sample products with durable 3 mil flat poly bags. These 4" x 6" flat poly bags are designed for organizing and protecting small items including jewelry findings, hardware components, electronics parts, craft supplies, and sample packets. Made from 100% virgin Low Density Polyethylene (LDPE) resin, these bags provide reliable protection for small-item storage, retail packaging, and shipping applications. The 3 mil thickness offers an ideal balance of durability and flexibility. LDPE film provides excellent tear resistance and puncture protection while remaining pliable enough to conform around irregularly shaped items. The material's superior clarity allows products to remain visible for easy identification and quality inspection without opening the bag. A durable bottom seal ensures contents stay secure during handling and transport. Key Benefits: Superior clarity for product visibility and quality inspection Durable bottom seal prevents leaks and product loss Heat sealable for tamper-evident closures FDA-compliant LDPE resin safe for indirect food contact Flexible enough to conform around irregular shapes Tear and puncture resistant for reliable protection Specifications: 4" x 6" | 3 mil | LDPE (Low Density Polyethylene) | 1000/case | FDA-compliant | Heat sealable Common Applications: Jewelry findings and components, small hardware (nuts, bolts, washers, screws), electronics components and parts, sample packets for cosmetics or food products, craft supplies and beads, trading cards and collectibles, small medical device components, fastener and bearing packaging. What are flat poly bags used for? Flat poly bags are open-top polyethylene bags used for packaging, organizing, and protecting products during storage and shipping. They can be heat sealed, tied, stapled, or taped shut depending on the application and desired level of security. What is the difference between LDPE and other plastic bag materials? Low Density Polyethylene (LDPE) is more flexible and softer than High Density Polyethylene (HDPE), making it ideal for conforming around irregularly shaped items. LDPE provides superior clarity compared to HDPE, though it will have slight haze compared to crystal-clear materials like polypropylene or BOPP film. Can these bags be heat sealed? Yes, LDPE flat poly bags are heat sealable using impulse sealers, constant heat sealers, or hand-held heat sealing tools. Heat sealing creates a tamper-evident closure that's stronger than tape or ties, making it ideal for retail packaging or securing valuable small parts.
