This 3″ × 4″ 2-mil LDPE reclosable zipper bag is a dependable choice for storing, sampling, and organizing items with a secure, resealable closure.
F20304H: 3″ × 4″ Heavy-Duty Reclosable Seal-Top Bags in 2.0 Mil LDPE
The F20304H is the heavy-duty version of LK Packaging’s 3″ × 4″ reclosable seal-top bag, made from 2.0 mil LDPE with reinforced construction for greater puncture resistance and seal integrity. This is the right choice when a 3×4 bag is needed but the contents include sharp metal edges, rigid angular corners, or abrasive surfaces that could puncture or compromise a standard-weight bag.
Metal Parts, Hardware Kits, and Sharp Component Packaging
Hardware distributors and precision parts suppliers use the F20304H to individually bag small items with punched, sheared, or machined edges — metal clips, locking tabs, stamped brackets, and cut metal components. The 3×4 footprint provides enough room for these flat metal items without oversized empty space that would allow the item to shift and repeatedly contact bag walls. Reinforced construction prevents the slow bag failure caused by repeated contact with sharp edges during shipping and handling.
Fishing Tackle and Sharp Lure Packaging
Fishing tackle manufacturers and retailers use the F20304H to bag hook-and-lure components, treble hooks, and terminal tackle with exposed points. The 3×4 size accommodates a wider range of lure sizes than the 3×3 square, and the heavy-duty construction handles hook points without puncture. Tackle variety packs assembled with pre-bagged components need heavy-duty bags to maintain integrity through retail display and storage.
Jewelry and Craft Findings with Sharp Pin Backs
Jewelry findings with exposed pin backs — brooch pins, tie tacks, and lapel pin clutches — can puncture standard bags when multiple pieces are bagged together. The F20304H’s reinforced walls maintain integrity when packaging these items individually or in small counts. The 3×4 format provides enough room for a jewelry piece plus a printed insert card.
How Does F20304H Compare to Standard F20304 and F20304VP?
The F20304H has reinforced construction for superior puncture resistance compared to the standard F20304. The F20304VP (1.4 mil economy) is at the opposite end of the spectrum — thinner and more cost-effective for lightweight non-sharp contents. Match the variant to the application: H for sharp/abrasive, standard for general use, VP for high-volume lightweight applications.
