Clear Pre-Opened Bags 4 mil

Clear Pre-Opened Bags on a Roll 4 mil are the heavy-duty version of our roll-format pre-opened bags — built for industrial packing lines that need both the speed of roll dispensing and the strength to handle heavier, sharper, or more demanding products without bag failure. At 4 mil thickness, these bags stand up to metal components, sharp edges, and rough handling that would quickly compromise lighter-gauge roll bags.

The pre-opened mouth design means bags are ready to load the instant they’re separated from the roll — no time wasted pulling apart bag layers by hand. Combined with perforations for clean, one-motion separation, these bags dramatically reduce per-unit packaging time on production lines handling heavier industrial products. The crystal-clear polyethylene film maintains full product visibility throughout the packing and shipping process.

These bags are commonly used in automotive parts packaging, hardware kitting, metal fabrication, MRO distribution, and any manufacturing environment where speed of bagging and film durability are both non-negotiable. Compatible with standard tabletop and inline heat and impulse sealers. Available in multiple widths to accommodate your specific product dimensions.
