Why Choose Slide Seal Reclosable Bags?
Slide seal bags (also called slider bags or reclosable poly bags) offer a superior closure mechanism compared to standard zipper bags. The plastic slider glides smoothly along the zipper track, creating an airtight seal that keeps food fresh and protects contents from moisture, dust, and contamination.
Common Uses for Slide Seal Bags
- Food packaging: Bakery items, candy, snacks, produce, bulk foods
- Retail packaging: Craft supplies, small parts, jewelry, cosmetics
- Storage: Leftovers, meal prep, freezer storage (3 mil is freezer-safe)
- Food service: Take-out portions, sample packs, grab-and-go items
- Industrial: Hardware, fasteners, electronics components
What Does "3 Mil" Mean?
Bag thickness is measured in mils (thousandths of an inch). Our 3 mil slide seal bags strike the perfect balance: thick enough to resist tears and punctures, yet flexible enough for easy handling. For reference:
- 1-2 mil: Light-duty (paper, clothing)
- 3-4 mil: Medium-duty (most food applications) ✅ You're here
- 6+ mil: Heavy-duty (sharp objects, industrial use)

Frequently Asked Questions
What is a slide seal bag?A slide seal bag is a reclosable poly bag with a plastic slider that glides along a zipper track to open and close it. Our slide seal bags are 3 mil FDA-compliant LDPE, sold in cases of 250, and are also called slider bags or reclosable poly bags. What is the difference between slide seal bags and zipper bags?Slide seal bags have a plastic slider that glides along the zipper track, so they open and close easily even with wet or gloved hands. Traditional zipper bags require pinching the zipper closed along its full length, which is slower and easier to seal incorrectly. Are slide seal bags food safe?Yes. Our slide seal bags meet FDA requirements for direct food contact under 21 CFR 177.1520 and are made from virgin LDPE resin with no recycled content, making them safe for fresh and frozen foods, baked goods, dry bulk ingredients, and ready-to-eat meals. Can you freeze food in slide seal bags?Yes, 3 mil LDPE slide seal bags are freezer-safe and will not crack at low temperatures. They are commonly used for meal prep, portion control, and long-term frozen storage. Are slide seal bags reusable?Yes. The slide seal closure can be opened and closed hundreds of times without losing seal integrity, so many customers reuse these bags for storage, organization, and travel.
