Poly Bags by Mil Strength

1. Start with the product weight and whether it has sharp or irregular edges.

2. Choose a bag size that allows the product to fit without excessive stretching.

3. Select film thickness based on expected handling and puncture risk.

4. Match the closure style to whether the bag needs to be sealed once or opened repeatedly.

Film thickness is one of the most useful ways to narrow a poly-bag assortment because it affects flexibility, puncture resistance, material use, and cost. Lightweight contents may not need the same gauge as hardware, parts, or products with corners. Bag dimensions and closure style still matter, so mil thickness should be evaluated together with the product shape and packing process. Thinner films are useful for lightweight products and applications where flexibility is the priority.

Mid-range gauges cover many everyday packaging, storage, and parts-handling needs. Thicker films provide additional puncture and tear resistance for heavier or more demanding contents. Film thickness is only one factor—also consider bag size, closure, product edges, and handling. Use the current product table and individual item details to confirm available sizes, materials, quantities, and specifications for the exact item you are considering.
