LK Packaging 6 x 9 Lab-Loc® Reclosable Specimen Bags Black 2 Mil

LK Packaging 6 x 9 Black Lab-Loc® Reclosable Specimen Bags, 2 Mil

LK Packaging’s 6 x 9 black Lab-Loc® reclosable specimen bags provide light-blocking containment for photosensitive specimens with the same 2 mil LDPE 3-wall construction and reclosable zipper closure as the standard Lab-Loc® line. The integrated document pocket keeps requisition forms with the specimen throughout the collection-to-analysis chain without direct specimen contact.

Which specimens require light-blocking packaging during transport?

Light-sensitive laboratory specimens include bilirubin, beta-carotene, porphyrins, vitamin B12, folate, and some therapeutic drug monitoring specimens. Exposure to fluorescent or ambient light during transport can cause photodegradation that alters test results, making black or amber containment essential for accurate reporting. LK Packaging’s black Lab-Loc® bags protect these specimens from the point of collection through laboratory receipt.

How does black LDPE protect specimens from light degradation?

Carbon black pigment in the LDPE film blocks visible and UV light transmission across the bag’s opaque walls. The 2 mil construction provides sufficient thickness to prevent light penetration even under extended transport durations in illuminated courier bags or pneumatic tube carriers. Unlike amber plastic containers, the bag’s opacity is achieved without restricting specimen container type or collection method.

Black specimen bags in neonatal and pediatric bilirubin testing workflows

Neonatal intensive care units collecting bilirubin specimens for phototherapy monitoring require rapid transport with light protection. LK Packaging’s black Lab-Loc® bags provide the necessary opaque containment for heel stick bilirubin specimens from NICU bedside to the stat laboratory, maintaining specimen integrity across the critical analysis window for jaundice management decisions in neonatal care.

Do black specimen bags meet OSHA bloodborne pathogen containment requirements?

Yes. LK Packaging’s black Lab-Loc® bags include biohazard symbol printing on the exterior to communicate hazard status to all handling personnel. This maintains compliance with OSHA 29 CFR 1910.1030 requirements while providing the light protection required for photosensitive specimen types commonly encountered in clinical chemistry and toxicology testing.
