• Heavy-duty 4 mil thickness provides exceptional resistance to tears, punctures, and abrasion — protecting contents reliably through shipping, handling, and long-term storage.
• 100% virgin LDPE resin delivers superior clarity, consistency, and structural integrity compared to bags made with recycled material blends.
• 3x impact resistance and 2x tensile strength versus traditional low-density polyethylene bags — engineered to withstand demanding packaging and handling environments.
• Heat-sealable construction allows secure closure to lock in freshness, prevent contamination, and add tamper evidence to finished packaged goods.
• FDA food-contact compliant — safe for direct contact with food, making these bags a reliable choice for produce, baked goods, bulk dry goods, and food service portioning.
• Large 12x30 format handles long, oversized, or bulky items that standard poly bag sizes can't fit — from garments and rolled goods to extended industrial parts.
• Made in the USA — Prism Pak brand bags are manufactured domestically to consistent, dependable quality standards.

Where it works best:

• Food service: bagging baked goods, sub sandwiches, bulk produce, fresh pasta, and long or oversized food items for portioning, sale, or distribution.
• Retail & e-commerce: packaging garments, posters, rolled documents, banners, scarves, and soft goods for clean, professional shipment.
• Industrial & manufacturing: protecting long parts, rods, pipes, tubing, and precision components from dust, moisture, and surface damage during storage or transit.
• Printing & design: storing and shipping blueprints, large-format prints, architectural drawings, and rolled artwork without creasing or moisture damage.
• Agricultural: bagging cut flowers, asparagus, leafy greens, and other long or bundled produce for market, grocery, or wholesale distribution.

Solves key pain points: Finding a poly bag large enough for long or bulky items — without sacrificing durability — is a common challenge across food service, manufacturing, and retail. These 12x30 bags solve that problem with a heavy-duty 4 mil build and a generous format that comfortably accommodates oversized goods. The 100% virgin LDPE material ensures crystal clarity for contents visibility and meets food-contact compliance standards, while heat-seal compatibility adds flexibility for businesses sealing bags on a production line or at the point of packaging.
