LK Packaging 13 x 18 Lab Seal® Tamper-Evident Specimen Bags Blue 1.8 Mil

This 13″ × 18″ 1.8-mil tamper-evident security bag is a dependable choice for secure transport of cash, evidence, and sensitive items.

LK Packaging 13 x 18 Lab Seal® Tamper-Evident Specimen Bags in Blue for Large Specimen Transport

LK Packaging 13 x 18 Lab Seal® Tamper-Evident Specimen Bags in Blue provide the large-format capacity needed for anatomical pathology specimens, wide-mouth specimen jars, multi-tube panel sets, and bulk biological collections requiring secure tamper-evident secondary containment. Manufactured from 1.8 mil low-density polyethylene with a 3-wall construction, these bags feature the Seal-N-Rip® one-time tamper-evident closure that creates visible integrity evidence for chain-of-custody documentation. The separate front document pocket isolates paper requisitions from the specimen compartment, preventing contamination of clinical paperwork during transport. LK Packaging biohazard printing satisfies OSHA 29 CFR 1910.1030 labeling requirements. The blue tint integrates into color-coded routing programs for high-volume laboratory receiving operations.

Why Large-Format Specimen Bags Need Tamper-Evident Closures

Large anatomical specimens, surgical tissue samples, and multi-container panel sets represent high-value clinical materials where chain-of-custody integrity carries significant medical and legal weight. A tamper-evident seal on large-format bags provides documented evidence that the specimen has not been accessed, substituted, or contaminated between the collection or surgical suite and the pathology laboratory. For medicolegal cases, organ biopsy specimens, or pre-transplant tissue evaluations, the tamper indication supports the integrity documentation required by accrediting bodies and risk management programs. The visible evidence of opening provides a clear audit indicator that standard zippered bags cannot provide.

13 x 18 Inch Format for Anatomical Pathology and Bulk Specimen Collections

The 13 x 18 inch dimensions accommodate formalin-fixed tissue biopsy containers, large urine collection bottles, blood culture bottle sets, and cytology specimen containers that exceed the capacity of standard 6 x 10 or 10 x 10 formats. Anatomical pathology departments receiving gross tissue specimens in wide-mouth specimen jars up to 12 inches in height benefit from the 18-inch bag length, which allows the jar to sit flat within the bag without forcing the adhesive flap to stretch. The document pocket on the 13-inch-wide face holds pathology requisitions, patient identification labels, and tissue submission forms in the clearly visible position expected by pathology accessioning staff.

Surgical Pathology Specimen Transport From Operating Room to Pathology Department

Hospital operating rooms transporting fresh and formalin-fixed surgical specimens to the pathology laboratory use large-format tamper-evident bags to maintain specimen integrity and documentation continuity from the surgical suite. OR staff place the specimen container, patient identification labels, and surgical requisition into the 13 x 18 bag, seal with the Seal-N-Rip® closure, and hand off to secure courier for transport to pathology. The blue designation can indicate urgent intraoperative consultation specimens requiring priority processing by the on-call pathologist, distinguishing them from routine surgical resection cases in the pathology receiving queue.

Is the 1.8 Mil Gauge Sufficient for Large Anatomical Specimen Containers?

The 1.8 mil low-density polyethylene film in LK Packaging Lab Seal® bags provides adequate strength for standard specimen jar and container transport. Laboratories transporting particularly heavy or sharp-edged containers should evaluate whether the gauge is appropriate for their specific application and consider pairing the bag with a secondary rigid transport container for added protection. LK Packaging also offers higher-gauge specimen containment solutions for applications requiring additional puncture or tear resistance. Contact your LK Packaging distributor to discuss the full range of specimen containment options for large-format pathology transport.
