Applications
The 18×20 in. footprint accommodates folded knit sweaters, crewnecks, and zip-front apparel in single-unit packaging for wholesale or direct-to-retail distribution. Additional B2B applications include large industrial parts kits and gasket sets, oversized document and drawing storage, bulk hardware assortments requiring organized resealable containment, and large medical or lab supply kit assembly. The reclosable zipper supports applications with multiple open-and-reclose cycles in receiving, QC, or fulfillment workflows.
Features
The reinforced side-welded zipper provides a consistent, secure closure that maintains alignment across repeated use. 2 mil LDPE balances flexibility with puncture resistance appropriate for soft goods, folded apparel, and clean-room or warehouse storage environments. Excellent clarity allows product identification and inspection without opening. The open-bottom fill format accommodates high-speed manual or semi-automated bagging operations.
Material Notes
100% virgin LDPE resin construction with FDA/USDA compliance supports use across food-adjacent, pharmaceutical, and clean-goods packaging applications. LDPE at 2 mil provides standard-duty protection for soft, non-abrasive contents. The reclosable zipper is integrally formed with the bag film — no added adhesive or mechanical fastener. All gauge specifications are nominal.
Use Case Notes
Apparel distributors and wholesale knit goods suppliers use 18×20 reclosable bags for folded garment protection during warehouse storage and multi-stop LTL shipment. The resealable format is particularly useful in returns processing, where garments require re-inspection and re-bag before restocking. Industrial MRO distributors use this size for pre-kitted hardware and gasket sets that require periodic access in the field. The 500-count case supports mid-volume operations without excess inventory burden.
Common Questions
What garment sizes does 18×20 accommodate? Folded men’s and women’s XL–XXL knit sweaters, crewnecks, and hoodies will generally fit within the 18×20 in. interior. Smaller folded garments (S–L) fit with additional headspace for tissue or care card inserts.
Is the zipper compatible with zipper pull aids or tamper-evident inserts? The standard side-weld reclosable zipper is a plain press-lock track. It is not pre-fitted for zipper pulls or tamper-evident seals, but standard aftermarket zipper aids are compatible with this track width.
Can these bags be used for food packaging? Yes. The 100% virgin LDPE resin meets FDA/USDA specifications for incidental food contact. They are appropriate for dry goods, fresh produce, and non-liquid food items where a resealable barrier is required.
Why Buy
Reinforced side-welded zipper construction and 100% virgin LDPE resin combine durability with compliance across apparel, industrial, and food-adjacent applications. The large 18×20 in. format fills a niche between standard reclosable sizes and custom oversize bags, reducing the need for bag-within-bag approaches for bulky folded goods. Available in 500-count cases for efficient per-unit cost at mid-to-high volume packaging throughput.
