• 4 mil heavy-duty strength provides over 3x the impact resistance and 2x the tensile strength of standard polyethylene bags, keeping contents protected against tears, punctures, and rough handling during shipping and storage.
• Generous 12x20 dimensions accommodate a wide range of products — from apparel and bedding to machine components, bulk food items, and large retail merchandise — with room to spare for easy loading.
• 100% virgin LDPE resin ensures consistent quality with no recycled contaminants, making these bags suitable for sensitive applications including food packaging, medical supplies, and clean-room products.
• FDA food-contact compliant for safe direct contact with food products, including baked goods, produce, dried goods, and more — meeting industry standards for commercial food service and retail.
• Heat-sealable construction allows you to create a secure, tamper-evident airtight seal to lock in freshness, prevent contamination, and protect product integrity through every stage of distribution.
• Crystal-clear transparency keeps contents fully visible for quick identification, barcode scanning, and professional retail display without removing the product from the bag.
• Made in the USA under strict manufacturing standards, ensuring reliable, consistent bag quality across every unit in every carton.

Where it works best:

• Food service: bulk grains, pasta, dried fruit, candy, snack mixes, baked goods, deli portions, and packaged dry goods.
• Retail & apparel: garments, T-shirts, towels, bedding, folded clothing, and accessories requiring a clean, professional presentation.
• Industrial & MRO: large hardware, machine components, tools, safety supplies, and fasteners needing protection from moisture and handling damage.
• Agricultural: seeds, fertilizer packs, plant materials, and garden products that require moisture-resistant, durable containment.
• Medical & sanitary: sterilized supplies, disposable devices, and clinical items needing contamination-free, compliant packaging.

Solves key pain points: Standard lightweight poly bags fail when products need real protection through warehousing, freight, and retail display. These 4 mil bags are specifically built to resist punctures and tears even in demanding distribution environments. The virgin LDPE resin construction ensures product purity throughout the supply chain — critical for food service and medical applications — while the roomy 12x20 opening makes loading fast and efficient, reducing time on the packaging line without adding bulk, weight, or waste to your operation.
