Compact 3x3 inch poly bags ideal for organizing small parts, hardware, and components with reliable protection and clear visibility. These 1.5 mil flat poly bags are designed for businesses and operations that need efficient, economical packaging for small items. From hardware distributors sorting screws and bolts to jewelry suppliers organizing findings, these compact 3x3 inch bags provide the perfect balance of protection and practicality. Manufactured from 100% virgin Low Density Polyethylene (LDPE) resin, each bag meets FDA/USDA specifications for food-contact compliance, making them suitable for both industrial and consumable applications. The LDPE construction delivers superior clarity for product visibility while maintaining the flexibility and puncture resistance needed for everyday use. Unlike rigid packaging, these lightweight bags conform to contents and maximize storage efficiency. Each bag features a durable bottom seal that provides reliable strength even when packed with dense hardware or components. The 1.5 mil thickness strikes an optimal balance—thin enough to be economical for high-volume use, yet strong enough to resist tearing during handling and storage. Key Benefits: Superior clarity allows instant product identification without opening the bag FDA-compliant virgin LDPE resin safe for direct food contact Flexible material conforms to contents, maximizing storage space Durable bottom seal prevents leaks and maintains bag integrity Multiple closure options: heat seal, tie, staple, or tape shut Economical 1.5 mil thickness reduces material costs without sacrificing protection Specifications: 3" x 3" | 1.5 mil | LDPE (Low Density Polyethylene) | 1000 bags/case | FDA-compliant | Bottom sealed Common Applications: Hardware and fastener packaging (screws, bolts, nuts, washers), jewelry component organization (beads, findings, clasps), small electronics parts storage, craft supply packaging, coin collecting and numismatics, pharmaceutical sample packaging, seed packet distribution, small tool and accessory bundling, laboratory specimen bags, and retail point-of-purchase packaging for small items. What are flat poly bags used for? Flat poly bags are open-top polyethylene bags used for packaging, organizing, and protecting individual items or small quantities of products. They're the most versatile and economical packaging solution for applications ranging from industrial parts storage to retail merchandise protection. What does 1.5 mil mean for poly bags? 1.5 mil refers to the thickness of the polyethylene film, equal to 0.0015 inches. This lightweight gauge is ideal for small, non-sharp items where puncture resistance is less critical than economy and clarity. For heavier items or those with sharp edges, consider upgrading to 2 mil or 4 mil bags for added durability. Can LDPE bags be heat sealed? Yes, LDPE (Low Density Polyethylene) bags can be heat sealed using an impulse sealer or hand-held heat sealer. LDPE has a low melting point that makes it ideal for heat sealing, creating an airtight closure that's more secure than tying or taping. These bags can also be tied, stapled, or taped shut for added convenience.
