Material and Process Details


This product uses medical-grade polypropylene (PP) material, produced through special co-extrusion process, forming a uniform thickness of 3 MIL transparent film. The inner layer is added with anti-static agent, surface resistivity controlled at 10^10-10^12Ω, effectively reducing contamination caused by static adsorption. The material undergoes low-temperature modification treatment, maintaining sufficient toughness in -40°C environments, without brittle cracking. The self-sealing zipper part uses food-grade PE material, high flexibility, long repeated use lifespan. Printing uses environmentally friendly water-based ink, no solvent residue, complying with USP Class VI level biocompatibility requirements for medical device packaging materials, passing ISO 10993-5 cytotoxicity testing.

Application Scenarios

Hospital Laboratory Department: Processing 500+ blood, urine, and other specimens daily, self-sealing zipper design reducing single specimen sealing time from 8 seconds to 3 seconds, work efficiency improved by 62%, sample cross-contamination rate reduced to below 0.02%.
Pathology Department Specimen Transfer: Tissue sections, biopsy samples, and other sensitive specimens safely transferred between different departments through biohazard bags, temperature marking system ensuring clear specimen preservation conditions, reducing specimen degradation rate by 75%, improving diagnostic accuracy.
Microbiology Laboratory: Processing 200+ culture samples weekly, medical-grade PP material providing excellent bacterial solution sealing performance, preventing pathogen leakage, protecting laboratory staff safety, reducing occupational exposure risk by 85%.
In-Hospital Specimen Transport: Specimen transport between different floors and departments averaging 350 times daily, biohazard symbols clearly visible, ensuring correct handling by transport personnel, specimen loss rate reduced from 5 times per month to zero, tracking management efficiency improved by 93%.

Usage Steps

Bag Preparation: Take a biohazard bag from the packaging, confirm the self-sealing zipper is intact, gently open the bag mouth, keeping the bag body expanded.
Information Marking: Use a specialized marker to fill in patient information, specimen type, collection time, and other data in the designated area on the bag, or attach pre-printed labels.
Specimen Placement: Place sealed primary containers (such as blood collection tubes, urine cups) into the bag, ensure the outer surface of the container is not contaminated, it is recommended to place only one specimen in a single bag to avoid confusion.
Temperature Selection: According to specimen preservation requirements, mark at "FROZEN", "REFRIGERATE", or "ROOM TEMPERATURE" temperature markings, clarifying specimen storage conditions.
Sealing Operation: Firmly grip the self-sealing strips on both sides of the bag, starting from one end, slide thumb and index finger along the zipper, a "click" sound indicates sealing is complete, check that the sealing strip is completely closed with no gaps.

Maintenance Guide

Storage Conditions: Should be stored in a clean, dry environment, temperature 15-30°C, relative humidity 40%-60%, avoid direct sunlight and humid environments, away from heat sources and chemicals.
Post-Opening Handling: Packages should be used within 6 months after opening, unused bags should be resealed in packaging to prevent dust contamination and static adsorption.
Quality Inspection: Before each batch use, sample 1% of the bags for self-sealing zipper function testing and sealing performance testing, stop using that batch of products if abnormalities are found.
Adverse Reactions: If bag discoloration, brittleness, self-sealing zipper function abnormalities, or other issues are found, stop using immediately and contact the supplier, while retaining samples and batch number information.
Waste Disposal: Used biohazard bags should be harmlessly disposed of according to medical waste disposal procedures, not discarded as ordinary garbage, avoiding environmental pollution and secondary hazards.
