13 x 18 Clear Reclosable Zip Bags (100 Count) - Heavy Duty Seal

In this review the Spartan Industrial 13 x 18 reclosable zip bags are evaluated for apparel packers, online sellers, and general storage users who need a reliable, heavy-duty clear bag. The bottom line: these 100-count, 4.0 mil virgin LDPE bags deliver a noticeably thick material and a strong, airtight seal that protects contents from moisture and dust. For anyone packing shirts, bulk baked goods, or parts, the bags combine durability and an easy one-touch zip closure that speeds up shipping and storage tasks without extra tools.

Key Features

• 100 Count Size: A full box of 100 bags keeps a steady supply on hand for repeated packing runs or long-term storage needs.
• 13 x 18 in Dimensions: The roomy 13 x 18 in interior (length excludes zipper) fits folded shirts, multiple bakery items, or medium-sized gear without forcing or folding.
• 4.0 Mil Thickness: The 4.0 mil clear virgin LDPE construction feels thick and durable, resisting punctures and handling better than thin sleeves.
• Secure Airtight Zipper: The resealable zip creates an effective water-resistant, airtight seal that helps protect merchandise from moisture and contamination.
• One Touch Seal: The self-sealing zipper allows fast, consistent closure without impulse sealers or tape, which speeds packing for small businesses.
• Food Grade Safe: Odorless and non-toxic material makes these bags suitable for storing baked goods, food items, and proofing dough in a pinch.

Who It's For

These bags are best for small apparel shops, online sellers, crafters, and household users who need a dependable, clear packaging option for shirts, garments, or bulk food items. The combination of size and strength suits those who pack multiple items per bag or want extra protection during shipping and storage.

Those who should look elsewhere include buyers who need archival, acid-free protection for delicate textiles or those requiring heavy industrial chemical resistance; the bags are sturdy but are made from LDPE and are not formulated for long-term museum storage or aggressive solvent exposure.
