This collection includes 4 mil reclosable poly bags designed for heavy-duty product protection, storage, and organization. Made from thick, durable polyethylene, these bags provide increased puncture resistance and strength compared to lighter-gauge options, making them suitable for sharp, bulky, or heavier items. Featuring a resealable closure, the 4 mil reclosable poly bags in this collection are commonly used in industrial, warehouse, and retail environments where secure containment, repeated access, and reliable protection are required.

4 Mil Reclosable Poly Bags

Poly bags are measured width x length. The opening is always on the width dimension (first dimension shown).

  • All poly bags are measured by inside usable dimensions (without the zipper or lip included in the size).
  • All reclosable poly bag sizes meet FDA and USDA specifications for food.
  • Your product's contents are always visible through these clear low density polyethylene bags.
  • The zipper type seal makes these bags reclosable and perfect for items that need to be kept fresh or repackaged.


Bag selection here is driven by three specs: size, thickness, and quantity. Use left-side filters to refine by width × length (in inches), mil thickness (commonly 1–4 mil), bag style (flat vs. reclosable where applicable), and case quantity (often 500 or 1,000 per case). Those filters help match puncture resistance and fit to your product and packing method.
