Heavy-duty flat poly bags designed for protecting large industrial equipment, machinery parts, and commercial products during storage and shipping. These 32" x 44" flat poly bags provide reliable protection for oversized items commonly used in manufacturing, warehousing, and distribution operations. Made from 100% virgin Low Density Polyethylene (LDPE) resin that meets FDA/USDA food-contact compliance standards, these bags offer the versatility to serve both industrial and food-service applications. The 4 mil thickness delivers superior puncture resistance compared to standard 2 or 3 mil bags, making these ideal for items with edges, corners, or irregular shapes that might tear thinner films. The heavy-duty construction protects against dust, moisture, and contamination during warehousing or transport, while the excellent clarity allows for easy product identification without opening the bag. Why 4 Mil LDPE Construction Matters: Low Density Polyethylene provides a unique combination of flexibility and strength. Unlike rigid materials that crack under stress, LDPE stretches and conforms to irregular shapes while maintaining its protective barrier. The 4 mil gauge — approximately four times thicker than a standard grocery bag — resists punctures from sharp corners, metal edges, and protruding hardware while remaining flexible enough to wrap around odd-shaped items. This material also offers excellent moisture resistance, preventing condensation damage during temperature changes in warehouses or shipping containers. Key Benefits: Heavy-duty 4 mil thickness resists punctures and tears from sharp edges and corners Excellent clarity for quick visual inspection and inventory identification FDA/USDA compliant for food-contact applications when needed Flexible LDPE construction conforms to irregular shapes and sizes Moisture barrier protection prevents condensation damage during storage Can be heat sealed, tied, stapled, or taped for secure closure 100% virgin resin — no recycled content that compromises strength Specifications: 32" x 44" | 4 mil | Low Density Polyethylene (LDPE) | 100 bags/case | FDA/USDA compliant | Bottom seal or side weld construction Common Applications: Machinery parts packaging | Industrial equipment covers | Warehouse component storage | Bulk product bundling | Manufacturing work-in-progress protection | Commercial furniture parts | Large item shipping and distribution What are flat poly bags used for? Flat poly bags are open-top polyethylene bags used for packaging, protecting, and storing products of various sizes. They provide a cost-effective barrier against dust, moisture, and contamination while allowing easy insertion and removal of items. What does 4 mil thickness mean for durability? A 4 mil gauge measures the film thickness at 0.004 inches, providing approximately four times the puncture resistance of standard 1 mil bags. This heavy-duty construction is ideal for items with sharp edges, corners, or irregular shapes that would tear thinner films during handling or storage. Can LDPE bags be heat sealed? Yes, Low Density Polyethylene is thermoplastic and can be easily heat sealed using impulse sealers, band sealers, or heat sealing irons. LDPE creates a strong, permanent seal at relatively low temperatures (250-350°F), making it ideal for secure packaging applications that require tamper-evident or airtight closures.
