Frequently Asked Questions
What is a 2 mil pre-opened bag?A 2 mil pre-opened bag is a 0.002" thick polyethylene bag wound on a roll with the front panel already slit open and the back panel perforated, so an automated bagger or a worker can drop the product straight in and tear the filled bag away. Ours are tubular with a durable bottom seal, wound on 3" cores with 1" diameter core plug holes, and available all clear or with a white front and clear back. Is 2 mil thick enough for my products?2 mil handles lightweight, soft, non-abrasive items up to about 2 to 3 pounds — apparel, textiles, documents, cables, and boxed cosmetics. If your product has sharp edges or corners, weighs more than 3 pounds, or takes rough handling in transit, step up to 3 mil for general-purpose use or 4 mil for industrial parts. How much do 2 mil bags save compared to 3 mil?2 mil bags typically run 30 to 40 percent less per bag than 3 mil bags of the same size, because you are buying a third less film. At 10,000 or more bags a month that gap adds up quickly, which is why high-volume apparel and e-commerce fulfillment operations run 2 mil wherever the product allows it. Are 2 mil pre-opened bags food safe?Yes — they are made from FDA-compliant polyethylene suitable for direct food contact. At 2 mil they are best suited to dry, lightweight food items such as snacks, candy, and bakery goods; heavier, moist, or sharp-edged products call for 3 or 4 mil. Verify compliance for your specific application. Will 2 mil bags work on my Autobag machine?Yes. Our 2 mil pre-opened bags are wound on 3" cores with 1" diameter core plug holes, the standard for Autobag® AB series and HS-100, 500, 550, 650 and 850 machines, Packway baggers, Rennco vertical baggers, and any equipment built for 3" cores. Check your machine's tension and seal-heat settings when switching to a thinner gauge. What size pre-opened bag do I need?Measure your product's length, width, and depth, then choose a bag 1 to 2 inches wider and 3 to 4 inches longer than the product so it loads and seals cleanly. Bag width is the flat measurement across the bag, not the circumference. Also confirm the maximum roll width your bagger accepts before ordering. Why Buy from Prism Pak?
