Sized 3″ × 3″ 2-mil LDPE, this reclosable zipper bag is well suited to storing, sampling, and organizing items with a secure, resealable closure.
F20303H: 3″ × 3″ Heavy-Duty Reclosable Seal-Top Bags in 2.0 Mil LDPE
The F20303H is the heavy-duty version of LK Packaging’s 3″ × 3″ reclosable seal-top bag, constructed from 2.0 mil LDPE with reinforced walls for increased puncture resistance. This format is the right choice when a 3×3 bag is needed but the contents include sharp edges, rigid metal corners, or abrasive surfaces that could compromise standard-weight bags during handling and storage.
Industrial and Hardware Applications for Heavy-Duty 3×3 Bags
Precision parts distributors, hardware packagers, and machine tool suppliers use the F20303H to bag small components with sharp edges — stamped metal brackets, cutting tool inserts, drill stops, and flat metal parts that have punched or sheared edges. The reinforced construction handles the point contact stress from sharp corners without developing pinhole punctures that would compromise contents in labeled storage.
Craft and Specialty Sharp-Item Packaging
Craft distributors packaging items like tile cutters, glass scoring tools, metal stamps with raised edges, and metal embossing dies use the F20303H to ensure bag integrity during shipping and display. The heavy-duty construction prevents the bag from tearing at contact points with rigid metal items, which is especially important for retail display packaging where the bag provides the only containment on a peg hook or shelf.
Fishing and Outdoor Gear Lure Components
Fishing tackle packagers use 3×3 heavy-duty bags for lure components and small terminal tackle with sharp hooks. The extra width compared to 2-inch wide bags allows hooks to sit flat without compressing the bag walls. The reinforced LDPE prevents hook points from puncturing the bag during packing, storage, and display in tackle retail environments.
When to Choose F20303H vs. Standard F20303
The F20303H is appropriate when contents have sharp edges, corners, or points that could puncture a standard bag. For soft, blunt, or non-abrasive contents — beads, fabric items, paper goods, foam shapes — the standard F20303 is sufficient and more cost-effective. Use the H variant only when the specific content profile requires it.
