LK Packaging 7 x 8 Medium Duty 1.9 Mil LDPE Flat Poly Bags for Hardware and Component Packaging

LK Packaging’s 7 x 8 medium duty flat poly bags deliver extra-thickness protection for small hardware sets, fastener kits, and component bundles that need more than standard gauge film provides. Made from 1.9 mil low-density polyethylene (LDPE), the KF0708MD is the step up from standard 1.4 mil bags — offering improved puncture resistance and a sturdier feel that communicates quality to end customers. The 7 x 8 footprint accommodates most small-parts packaging needs with an efficient bag-to-product fit ratio.

How Does 1.9 Mil LDPE Compare to Standard 1.4 Mil for Small Parts?

The additional 0.5 mil of thickness translates to roughly 35% more material — enough to contain sharp edges from stamped metal parts, bolt threads, and plastic gear teeth that would puncture or stress standard gauge bags over time in transit. LDPE at 1.9 mil also has enhanced flexibility in cold environments compared to LLDPE, which can be critical for industrial distributors shipping to facilities in northern climates where bags are handled in cold warehouse conditions.

Which Small Business Packaging Scenarios Benefit from 7 x 8 Medium Duty Bags?

Hardware stores, electronics assembly operations, and plumbing supply distributors frequently rely on the 7 x 8 medium duty format for multi-piece component sets. A single bag can hold nuts, bolts, and washers for a furniture assembly kit or a set of electrical terminal connectors with associated hardware. The clear film allows inventory staff to read part numbers through the bag without opening, reducing picking errors in high-volume warehouse environments.

Packaging Small Electronic Control Boards for Safe Transit

Electronics manufacturers shipping small PCBs in the 4–6 inch range use medium duty bags like the KF0708MD to provide a physical barrier against contact damage during shipment. While anti-static bags are used for ESD-sensitive components, the KF0708MD excels for non-ESD mechanical assemblies — control panels, terminal blocks, and relay modules — where the primary risk is physical abrasion rather than static discharge. The 1.9 mil LDPE provides enough stiffness to keep boards from bending in padded envelopes.
