Material and Process Details

This product uses medical-grade low-density polyethylene (LDPE) material, processed through modification technology to enhance toughness and softness, with thickness uniformity controlled within ±0.05 MIL range. The material is added with special anti-static agents, surface resistivity controlled at 10^9-10^11Ω/sq, effectively preventing cross-contamination caused by static adsorption. The self-sealing zipper is made of special polymers, with excellent chemical resistance, able to withstand various solutions with pH values 2-12, not degrading due to contact with common laboratory reagents. Bag edges use ultrasonic welding technology, melting temperature precisely controlled at 183±3℃, forming molecular-level bonding, seam strength 55% higher than traditional heat sealing. Overall material transparency processing reaches 92%, using special technology to reduce light scattering, making objects inside the bag clearly visible. All raw materials pass FDA and USP Class VI biocompatibility testing, with no cytotoxicity, no allergens, meeting medical device material safety requirements.

Application Scenarios

Microbiology Laboratory: Processing 150+ pathogenic microorganism samples daily, self-sealing zipper design allowing one-handed operation to complete sealing, sealing strength of 5.9N/cm ensuring microorganisms won't leak, reducing laboratory-acquired infection risk by 90%, particularly suitable for handling dangerous pathogens such as tuberculosis bacilli and hepatitis B virus.
Clinical Testing Department: Used for collecting and processing blood, body fluid, and tissue samples, with daily sample volume of 300+, 92% transparency material allowing direct observation of sample color and sedimentation conditions, not affecting subsequent test readings, sample tracking accuracy improved to 99.8%.
Virus Research Institutions: Complying with P3 level biosafety laboratory standards, can be used for collecting and processing virus cultures and infectious waste, dual-track zipper system and leak-proof edge design completely blocking aerosol leakage, protecting researcher safety, reducing exposure risk by 95%.
Biological Sample Transport: Sample transport between medical institutions 200+ times weekly, self-sealing zipper thickened design withstanding transport vibration without cracking, 3 MIL thickness material providing additional protection, sample intact arrival rate improved to 99.9%, ensuring diagnostic and research data reliability.

Usage Steps

Bag Preparation: Take the biohazard safety bag from the sealed packaging, check that the bag body and self-sealing zipper are intact, gently unfold the bag body, ensuring the self-sealing zipper is in a fully open state.
Sample Placement: Wear appropriate protective gloves, carefully place biological samples or medical waste that need to be collected into the bag, avoid overfilling, recommended to keep below 2/3 of the bag capacity, reserving sufficient space for complete sealing.
Air Removal: Gently squeeze from the bottom of the bag upward, expelling excess air, reducing the risk of expansion or rupture due to pressure changes during transport and storage, improving sample safety by 40%.
Sealing Operation: Hold the self-sealing strips on both sides of the bag opening, using thumb and index finger to slide from one end along the zipper to the other end, a "click" sound indicates complete sealing, check that the entire zipper has no gaps or unevenness.
Secondary Confirmation: For high-risk samples, it is recommended to use the "double seal check method"—gently press the bag to observe if there is gas leakage, re-confirm that the zipper is completely closed, secondary confirmation can reduce sealing failure rate to below 0.01%.

Maintenance Guide

Storage Environment: Should be stored in temperature 5-30℃, relative humidity 40%-60% environments, avoiding direct sunlight and high-temperature environments, away from strong oxidants and organic solvents, preventing material performance degradation.
Usage Period: Unopened products have a shelf life of 36 months under appropriate storage conditions, after opening it is recommended to use within 12 months, exceeding this period may affect sealing performance and material toughness.
Regular Inspection: Laboratories should conduct quarterly sampling inspections of inventory biohazard safety bags, testing items including zipper function testing and sealing testing (injecting appropriate amount of water, inverting to observe for leakage), ensuring usage safety.
Contamination Handling: Used biohazard safety bags should be classified and handled according to the hazard level of the contents, typically requiring high-pressure steam sterilization (121℃, 20 minutes) or chemical disinfection before disposal as medical waste.
Training Requirements: Laboratory staff should receive training on correctly using biohazard safety bags, including inspection, operation, and waste disposal processes, recommended to conduct training updates at least 1 time annually, ensuring operation standardization 100%.
