LK Packaging 6 x 6 Lab-Loc® No-Print Reclosable 3-Wall Specimen Bags 2 Mil

LK Packaging 6 x 6 Lab-Loc® No-Print Reclosable 3-Wall Specimen Bags for Custom and Research Use

LK Packaging’s 6 x 6 Lab-Loc® no-print specimen bags deliver the same three-wall reclosable construction as the standard printed version — without biohazard symbol or pre-printed text — making them ideal for research laboratories, industrial sample collection, and specialty applications where custom labeling or alternate marking systems are required. The LAB20606NP’s blank polyethylene surface accepts laser-printed labels, adhesive barcode labels, and hand-applied identification markers without conflict from pre-existing print elements.

What Is the Difference Between Printed and No-Print Specimen Bags?

Standard Lab-Loc® specimen bags feature pre-printed biohazard symbols and regulatory text required for clinical biological specimen transport under OSHA’s bloodborne pathogen standards. The no-print version (NP) omits this pre-printed content, providing a clean surface for applications where the printed content is not required or where custom labeling systems must be the primary identification method. Research institutions and non-clinical sample collection operations frequently require the no-print format to avoid regulatory language that could create compliance confusion outside clinical settings.

Which Laboratories Specify No-Print Specimen Transfer Bags?

University and pharmaceutical research laboratories, environmental testing facilities, food safety testing labs, and industrial quality control departments are the most common users of no-print specimen bags. These operations collect samples that may not fall under OSHA bloodborne pathogen definitions but require the same organized, document-plus-specimen bag format for chain-of-custody sample management. The no-print format also suits veterinary diagnostic laboratories where human biohazard symbology can create regulatory classification ambiguity.

Research and Academic Laboratory Sample Organization and Chain of Custody

Academic research laboratories running multi-site clinical trials, observational studies, and biobank collection protocols rely on no-print specimen bags to avoid pre-printed clinical indicators that could introduce bias or misclassification in blinded study designs. The document pocket in the LAB20606NP holds the research protocol identifier, participant ID code, and collection timestamp without exposing the specimen container to external contamination, while the blank bag surface is used for study-specific barcode labels that integrate with laboratory information management systems (LIMS).

Where Can Research Labs Order the LAB20606NP in Bulk from NFCbags.com?

LK Packaging’s LAB20606NP no-print specimen bags are available at NFCbags.com in case quantities for research institutions, environmental labs, and industrial testing facilities. NFCbags.com stocks the full Lab-Loc® line including both printed and no-print variants, enabling purchasing departments to source both formats from a single supplier with consistent quality standards. Contact NFCbags.com for case pricing, shipping lead times, and options for recurring delivery on the LAB20606NP.

Are No-Print Lab-Loc® Bags the Same Quality as Printed Versions?

Yes — the LAB20606NP uses identical 2 mil polyethylene construction, reclosable zipper, and 3-wall architecture as the standard printed LAB20606. The only difference is the absence of pre-printed content on the bag surface. The polyethylene film quality, zipper closure strength, and document pocket capacity are equivalent across all Lab-Loc® variants. Institutions that require both printed and unprinted variants can order both through NFCbags.com and rely on consistent construction quality across the full order.
