Mil Thickness Guide
At 3 mil thickness, these bags fall in the heavy-duty category. They provide substantially more protection than standard 1.5-2 mil bags, resisting punctures from sharp corners on matted prints, frame hardware, and stacked inventory. For extremely fragile or high-value items, consider pairing with cardboard stiffeners or upgrading to our 4 mil options for maximum protection.
Storage and Handling
Store bags in a cool, dry environment away from direct sunlight to maintain clarity and prevent premature aging. LDPE bags remain flexible in cold temperatures, making them suitable for warehouse environments without climate control. For archival applications, ensure prints are fully dry before bagging to prevent moisture entrapment.
