F20304: 3″ × 4″ Reclosable Seal-Top Bags in 2.0 Mil LDPE
The F20304 is a 3-inch wide by 4-inch tall reclosable seal-top bag in 2.0 mil clear LDPE. The 3×4 format is one of the most versatile and widely used sizes across jewelry, retail, hardware, pharmaceutical, and food packaging applications. It is large enough for most standard small items — folded gift cards, earring pairs with card backing, small hardware kits, and single packaged food samples — while remaining compact enough for high-volume peg display or drawered storage.
Jewelry Retail and Display Packaging
The 3×4 size is a standard jewelry retail bag format. Earring pairs on standard cards, pendants with pricing cards, ring-and-earring gift sets, and bracelet samples all fit neatly inside. The 4-inch height provides room for a jewelry card plus the item without crowding. Artisan jewelry makers and boutique retailers use this as their default bag size for general merchandise packaging at shows and in retail display cases.
Retail Gift Shop, Novelty, and Collectible Packaging
Gift shops and collectible retailers use the 3×4 bag for a wide range of small merchandise — enamel pins in sets, small folded art prints, magnets, rubber stamps, and packaged novelty items. The 3-inch width accommodates standard business card and gift card dimensions, making this size ideal for packaging cards with items. The reclosable seal top allows display bags to be opened by customers for inspection and resealed for purchase.
Hardware, Pharmaceutical, and Food Sample Applications
Hardware distributors use 3×4 bags for small fastener assortments, hardware kits, and component groups. Pharmaceutical suppliers use this size for individually packaged clinical samples, pill packets, and unit-dose supply kits. Food manufacturers use it for single-serving samples of flat packaged goods like powders, tea bags, and individual spice servings. FDA-compliant LDPE construction is appropriate for direct food and pharmaceutical contact.
How Does the F20304 Compare to F20303 and F20304H?
The F20304 is one inch taller than the F20303, providing additional depth for items that are slightly taller than a 3-inch bag allows. The F20304H is the heavy-duty reinforced version for sharp or abrasive contents. The F20304VP is the economy 1.4 mil version for high-volume, cost-sensitive applications.

LK bags are far better than the generic Chinese plastic zip bags. With ‘other’ bags you are either fighting to get the zipper open or you get bags that won’t stay closed. And with decent pricing from NFC – you can’t go wrong.
