Secure, reclosable protection for laboratory samples, medical supplies, and precision components. These 5" x 12" reclosable bags combine heavy-duty 4 mil LDPE construction with a reinforced side-welded zipper for reliable, reusable storage. The narrow-but-tall design is ideal for test tubes, medical instruments, long hardware parts, and specialty items that require organized, contamination-free storage. Made from 100% virgin Low Density Polyethylene (LDPE) resin meeting FDA and USDA specifications for food-contact safety. The reinforced zipper closure creates an airtight seal that opens and closes repeatedly without losing grip strength. Unlike cheaper bags with flimsy zippers that fail after a few uses, the side-welded construction anchors the zipper tracks securely to the bag body, preventing separation even when handling heavier items. The 4 mil thickness provides puncture resistance while maintaining enough flexibility for easy handling in laboratory, medical, and industrial settings. Key Benefits: Reinforced zipper: Side-welded construction prevents zipper separation during repeated use FDA-compliant material: Safe for direct food contact and medical-grade applications Superior clarity: LDPE film provides excellent visibility for quick content identification Heavy-duty 4 mil: Puncture-resistant thickness protects contents from damage Reusable design: Durable zipper closure withstands multiple open-close cycles Economical packaging: 1000 bags per box for high-volume operations Specifications: 5" x 12" | 4 mil | LDPE (Low Density Polyethylene) | 1000/box | Reclosable zipper | FDA/USDA compliant Common Applications: Laboratory sample storage (test tubes, pipettes, specimen containers) • Medical supplies (exam gloves, syringes, surgical instruments) • Hardware parts (long bolts, screws, dowels, fasteners) • Electronics components (cables, wire assemblies, connectors) • Food packaging (breadsticks, asparagus, long cookies, pretzel rods) • Craft supplies (paintbrushes, markers, knitting needles) What are reclosable zipper bags? Reclosable zipper bags feature interlocking plastic tracks that press together to create an airtight seal and can be opened and closed repeatedly. The side-welded design anchors the zipper to the bag body for added strength compared to standard press-to-close bags. What mil thickness is best for laboratory and medical use? 4 mil bags provide excellent puncture resistance for most laboratory and medical applications without being overly stiff. This thickness protects against tears from sharp edges while remaining flexible enough for easy handling and storage in tight spaces. Are these bags safe for food contact? Yes, these bags are manufactured from 100% virgin LDPE resin that meets FDA and USDA specifications for direct food contact. They are safe for storing dry food items, though they are not designed for vacuum sealing or sous vide cooking.
