Biohazard Specimen Transport Bags Manufacturers, Suppliers, Factory

1. Brief Introduction

(1) Product Description

Biohazard specimen bags are used by hospitals laboratories and diagnostic centers to provide secondary containment for biological samples during transport and storage.
Reliable performance depends on seal integrity mil thickness document pouch separation and printed warnings rather than unit price alone.
Multiple sizes wall configurations and materials are available to match different specimen containers and procurement scenarios.

(2) Applicable Scenarios & Target Audience

Channel Type	Applicable Scenario	Target Audience
Clinical Use	Specimen collection and inter-department transport within hospitals and clinics	Hospitals and clinical staff
Laboratory / Diagnostic	Secondary containment for samples sent to reference and diagnostic labs	Diagnostic centers and lab networks
Distribution	Bulk stocking across multi-site healthcare networks	Distributors and medical supply wholesalers
Custom / OEM	Branded and barcode-printed bags for standardized packaging across locations	Procurement teams at hospital systems and diagnostic chains

(3) Bag Format Types

Available in standard preprinted zipper bags for routine specimen transport
Available in custom biohazard specimen zipper bags with branding barcodes and language fields
Available in bulk wholesale packs for high volume procurement
Each format is designed to match its intended container size and handling workflow

(4) Closure & Document Pouch Design

Resealable zipper closure provides a fast liquid-tight seal for secure transport
Built-in tear strip allows quick one-hand opening when resealing is not required
Separate outer document pouch keeps requisition forms dry and isolated from the specimen

(5) Seal Integrity & Leak-proof Performance

Full seam seal and zipper closure are tested to reduce leakage claims during transport
Bags remain flexible through refrigeration and freezing without cracking the seal
Sample testing verifies dimensions mil thickness seam integrity and leak-proof performance against set acceptance criteria

2. Basic Specifications

Biohazard specimen bags are typically supplied in a handful of standard footprints sized to common blood tube urine cup and swab containers, with custom dimensions available for non-standard primary containers. Film gauge is generally specified in mil rather than by a single universal thickness: a 2 mil LDPE film is the common baseline for routine courier transfers, while a heavier 3 to 4 mil gauge is recommended for automated sorting long-haul shipment or cold-chain transport. Bags are most often supplied clear so contents remain visible, packed in cases of 1000 for standard sizes, with smaller counter packs available for lower-volume or trial orders. Packaging counts and carton configurations can be adjusted to suit freight volume and warehousing needs.

Item	Specification	Remarks
Size (L x W)	6 x 9" (15.24 x 22.86cm) 8 x 10" (20.32 x 25.4cm) 12 x 15" (30.48 x 38.1cm)	Custom sizes available
Bags per Case	1000 bags per case (standard 6 x 9" and 8 x 10" sizes) 500 bags per case (larger 12 x 15" size)	Small counter packs of 100 bags available for retail or trial orders
Film Color	Clear transparent film with black and red biohazard warning print	Custom colors and multilingual printing available
Thickness	Standard: 2 mil (50 microns) Heavy-duty: 3-4 mil (75-100 microns)	Mil thickness customizable by container weight; heavy-duty grade improves leak resistance and cold-chain performance
Qty per Carton	1000 pcs/case x 4 cases/carton = 4,000 pcs/carton 100 pcs/pack x 10 packs/case = 1,000 pcs/case	Packaging configuration adjustable by size and thickness for volumetric weight calculation

3. Material & Safety

Biohazard specimen bags in the market are manufactured predominantly from low-density polyethylene film, valued for its clarity flexibility and reliable heat-sealing performance. Quality bags use a 3-wall construction with a dedicated outer document pouch so requisition forms stay separate from the specimen, and close with a resealable zipper paired with a built-in tear strip for fast one-time opening. Because sharps such as needles or broken glassware can compromise film integrity, they belong in a dedicated sharps container rather than a specimen bag. Handling and packaging practices are generally referenced against frameworks such as OSHA's Bloodborne Pathogens Standard and IATA/DOT UN 3373 requirements for biological substances, and bags are typically BPA-free and latex-free with compliance documentation available on request for the target market.

Item	Specification	Remarks
Raw Material	LDPE (low-density polyethylene) virgin resin film	Material formulation matched to mil thickness and load for seam and zipper integrity
Wall Construction	3-wall design with separate document pouch (standard) 4-wall heavy-duty configuration available	Document pouch keeps requisition forms dry and isolated from the specimen
Closure Type	Resealable zipper closure with built-in tear strip	Zipper provides a fast liquid-tight seal; tear strip allows quick opening when resealing is not required
Regulatory Reference	OSHA Bloodborne Pathogens Standard 29 CFR 1910.1030 IATA/DOT UN 3373 packaging requirements for biological substances	Applicable frameworks for secondary containment and biohazard labeling
Note: All bags are BPA-free and latex-free. Relevant compliance documentation (FDA registration, USDA-compliant resin, REACH, RoHS, etc.) can be provided based on the target market. Sharps such as needles or broken glassware must not be placed in a specimen bag and should be routed to a dedicated sharps container.

4. Product Physical Properties

Film-level physical properties determine whether a specimen bag holds up under routine handling refrigeration and freezing without seam or zipper failure. For a representative 2 mil LDPE film, tensile strength and elongation at break indicate how much stress and stretch the film tolerates before tearing, dart impact reflects puncture resistance from drops or rough handling, and seam strength reflects the reliability of the zipper weld under load. Reputable suppliers validate these figures against thickness-to-load and cold-chain criteria before production, so buyers can specify mil thickness by container type rather than relying on a generic one-size bag. The figures below are representative factory reference values; certified test reports can be supplied for a given production batch.
