Poly Bags for Industrial, Food & Shipping Applications
Over 2,400 poly bag SKUs — reclosable, flat, gusseted, anti-static, food-safe, and specialty bags in every size and thickness.
Poly bags are one of the most versatile packaging materials in any warehouse or production facility. From small reclosable zip bags for parts storage to large gusseted bags for product protection, Material Handling USA carries the widest selection of polyethylene bags available.
Our flat poly bags range from 1.5 mil (light duty) to 6 mil (heavy duty) in hundreds of width and length combinations. Reclosable zip-top bags are available in standard, heavy-duty, write-on, and colored varieties. Gusseted bags offer extra capacity for bulky or irregularly shaped items.
Specialty poly bags include food-grade bags (FDA compliant), anti-static pink poly bags for electronic components, VCI bags for corrosion-sensitive metal parts, and freezer-grade bags rated for sub-zero storage.
All bags are available by the box (typically 100–1,000 per box depending on size) with case quantity discounts. Custom printed poly bags available by special order.

Frequently Asked Questions
What mil thickness should I use for poly bags?
1.5–2 mil is suitable for light-duty applications like retail display. 3–4 mil is standard for parts storage and general purpose. 4–6 mil is heavy-duty for sharp or abrasive items. Food applications typically use 2–3 mil FDA-compliant film.
What's the difference between LDPE and HDPE poly bags?
LDPE (low-density polyethylene) bags are soft, flexible, and clear — ideal for general storage and display. HDPE bags are stiffer, crinkly, and slightly cloudy — they offer higher tensile strength and are often used for grocery-style bags. Most industrial flat and zip bags are LDPE.
Are your poly bags food safe?
Yes — our food-grade poly bags are manufactured from virgin (not recycled) polyethylene and meet FDA 21 CFR requirements for food contact. These are suitable for direct food contact including packaging, storage, and freezer applications.
Can I get custom-size poly bags?
Yes. We can source custom widths, lengths, and thicknesses with typical lead times of 2–4 weeks for domestic production. Contact our team at (800) 326-4403 for a custom quote.
