9X12 4 Mil 1000/CTN Flat Poly Bag

Dependable, heavy-duty flat poly bags for food service, retail, and industrial packaging — all in one versatile 9x12 size. These bags are manufactured from 100% virgin Low-Density Polyethylene (LDPE) resin, engineered to provide over three times the impact resistance and twice the tensile strength of standard LDPE bags. Heat-sealable and food-contact compliant, they protect everything from baked goods to hardware components — and ship within 24 hours of your order.

Size: 9" x 12" | Thickness: 4 mil | Material: 100% virgin LDPE | Quantity: 1,000 bags per carton | Compliance: FDA food-contact compliant

• Heavy-duty 4 mil thickness provides superior resistance to tears, punctures, and abrasion — keeping contents secure through handling, transit, and demanding storage conditions.
• 100% virgin LDPE resin delivers crystal-clear film, consistent wall strength, and reliable performance — no compromises from recycled material.
• FDA food-contact compliant for safe direct contact with baked goods, candy, deli items, produce, and portioned snacks.
• Heat-sealable construction lets you create an airtight seal to lock in freshness, prevent contamination, and give every package a clean, professional finish.
• Made in the USA to rigorous quality standards — Prism Pak brand bags are built to outperform imported alternatives in strength, clarity, and consistency.
• Crystal-clear LDPE film keeps contents visible for easy identification, retail display, barcode scanning, and quality inspection without opening the bag.
• 1,000 bags per carton supports high-volume operations with a cost-effective price-per-bag that keeps packaging costs in check without sacrificing quality.

Where it works best:

• Food service & bakeries: portion cookies, muffins, bread loaves, deli cuts, chocolates, and candy — with full food-contact compliance.
• Retail & e-commerce: package folded apparel, accessories, promotional bundles, gift items, and small consumer goods for a clean, professional presentation.
• Industrial & manufacturing: store and label hardware, fasteners, bolts, small tools, auto parts, and assembly components securely.
• Medical & laboratory: protect sterile supplies, specimens, documents, and sensitive equipment in controlled or clinical environments.
• Craft, hobby & print: store fabric swatches, printed materials, art supplies, beads, and project kits in moisture-resistant, clearly visible packaging.

Solves key pain points: Thin bags fail when you need them most — mid-shift breakage wastes product, slows production, and risks customer complaints. These 4 mil flat poly bags are built with extra wall thickness to handle real-world demands: heavier contents, rough shipping conditions, and repeated handling on the line. Heat-seal compatibility means you close bags quickly without tape, twist ties, or staples — cutting steps from your workflow and delivering a more professional result. And because they are food-contact compliant, one bag works across food and non-food applications, reducing the number of SKUs you need to stock.
