Key Features & Benefits

• Heavy-duty 4 mil thickness provides over 3× the impact resistance and 2× the tensile strength of conventional LDPE bags, protecting contents from punctures, tears, and moisture in storage and transit.
• FDA food-contact compliant — crafted from 100% virgin LDPE resin meeting FDA/USDA specifications, making these bags safe for direct food contact across food service and production environments.
• Crystal-clear visibility lets you identify contents at a glance, scan barcodes without opening, and present products attractively for retail display or inspection.
• Heat-sealable construction allows secure closure for freshness retention, tamper resistance, and professional product presentation from packaging line to customer hands.
• Made in the USA from premium virgin polyethylene resin — consistent gauge, reliable sealing performance, and quality you can trust batch after batch.
• Bulk 1,000-count case reduces per-unit cost and keeps high-volume operations stocked without constant reordering.
• Versatile open-top design accommodates a wide range of products — load, seal, label, or fold as your packaging workflow demands.

Where it works best:

• Food service: packaging cookies, baked goods, candies, dried spices, snacks, and meal kit components
• Retail & e-commerce: poly-bagging folded apparel, soft goods, accessories, and lightweight consumer products for direct-to-consumer fulfillment
• Industrial & manufacturing: organizing hardware kits, fasteners, gaskets, foam inserts, and multi-component parts sets
• Warehouse & storage: protecting inventory from dust, moisture, and contamination during long-term storage or transit
• Crafts & specialty retail: packaging fabrics, craft supplies, prints, documents, and flat collectibles

Solves key pain points: Thin bags tear under load. Undersized bags waste time repackaging. These 12x12, 4 mil flat poly bags eliminate both problems. The heavy-duty LDPE construction resists punctures and tears that compromise product quality, while the generous 12x12 footprint accommodates a wide range of SKUs without multiple bag sizes cluttering your operation. Heat-seal capability locks in freshness for food products and adds tamper-evident security for retail. With 1,000 bags per case, you spend less time reordering and more time shipping.
