• Heavy-duty 4 mil construction delivers over three times the impact resistance and twice the tensile strength of standard poly bags — protecting large, heavy, or sharp-edged contents from tears and punctures in transit and storage.
• Generous 18 x 30 format handles oversized items that standard bags can't accommodate, from bulk food goods and large garments to printed materials and industrial components.
• FDA food-contact compliant virgin LDPE resin makes these bags safe for direct food packaging — produce, baked goods, dried foods, grains, and more.
• Crystal-clear visibility lets you see contents at a glance, cutting down on errors in packing lines, warehouse picking, and retail display.
• Heat-sealable design allows secure closure for freshness retention, airtight storage, or tamper-evident packaging without additional equipment.
• Made in the USA using Prism Pak's proprietary LDPE resin formula — consistent gauge, reliable strength, and uniform clarity in every carton.
• In stock, ships within 24 hours — no delays, no back-order risk. Prism Pak maintains ready inventory so your operation never runs short.

Where it works best:

• Food service & grocery: bag large loaves of bread, whole produce, bulk grains, flour, dried beans, and oversized baked goods safely and compliantly.
• Retail & apparel: protect folded garments, linens, large apparel items, and towels for presentation, storage, or shipping.
• Printing & media: safeguard posters, blueprints, large-format prints, foam core boards, and archival documents from moisture and handling damage.
• Industrial & manufacturing: wrap machine parts, metal sheets, foam panels, and equipment components for clean storage or shipment.
• Agriculture & floral: bundle cut flowers, large plant cuttings, or wrap bulk agricultural products for market or transport.
• Warehouse & fulfillment: use as oversized product liners, protection sleeves, or void-fill wraps inside outbound cartons.

Solves key pain points: When you're working with large, bulky, or high-value items, undersized or flimsy bags create damage and waste. These 18 x 30, 4 mil bags eliminate that problem — wide enough, long enough, and strong enough to handle the job without improvising. The heat-seal compatibility locks in freshness for food products or provides tamper evidence for retail items. Because they're FDA food-contact compliant, you don't need to maintain separate inventories for food and non-food packaging — one bag covers both.
