Material and Process Details

Made of medical-grade modified polymer composite material, with main components being specially modified high-density polyethylene (HDPE) and polypropylene (PP), with added special toughening agents and chemical stabilizers. The material thickness is precisely controlled at 0.08±0.003mm, far exceeding the minimum thickness of 0.05mm required by the national standard GB 19217-2011, providing more reliable physical protection.

The product is manufactured using advanced co-extrusion composite technology, forming a three-layer functional structure: the outer layer uses high-strength HDPE, providing basic strength and printing suitability; the middle layer adds special barrier agents, forming an effective barrier against microorganisms and chemicals; the inner layer uses chemical corrosion-resistant modified PP, resistant to various laboratory reagents. The three layers work together to ensure excellent performance even under harsh conditions.

The biohazard symbol is printed using special chemical corrosion-resistant ink, with strong printing adhesion, not easily fading or peeling off, maintaining clarity even with long-term exposure to laboratory disinfectants and chemical reagents. The symbol design strictly follows ISO 7000 and GB 19217 standards, with conspicuous black trefoil biohazard patterns printed on a bright orange-yellow background, with high visual recognition.

The bag bottom adopts patented "star-shaped" heat-sealing technology, with a heat-sealing strength of 22N/15mm, 2.5 times that of ordinary heat-sealing, thoroughly solving the problem of traditional laboratory waste bags easily leaking from bottom corners when loading liquid or heavy items. It also includes special anti-static treatment, with surface resistivity controlled within the range of 10^9-10^12Ω, reducing static accumulation, lowering the risk of sparks and dust attraction.

Application Scenarios

PCR Laboratory: Conducts nucleic acid amplification experiments, generating a large amount of waste potentially containing gene fragments. Thickened laboratory medical bags can safely collect discarded reaction tubes, tips, etc., with BFE 99.9% filtration efficiency ensuring no gene contamination spread, ensuring the accuracy of experimental results.
Microbiology Laboratory: Cultivates and studies various microorganisms. Clear biohazard symbols remind laboratory personnel to pay attention to safety, with 0.08mm thickness providing reliable protection, effectively preventing microorganism leakage causing environmental contamination and laboratory infections.
Virus Laboratory: Handles high-risk virus samples, with extremely high requirements for waste bags. Thickened design and excellent barrier performance ensure viruses will not spread through waste leakage, complying with the strict biosafety requirements of BSL-2 and BSL-3 laboratories.
Medical Testing Laboratory: Analyzes various clinical samples, generating a large amount of waste potentially containing pathogens. The acid-alkali resistance range of pH 0-14 enables safe collection of waste in contact with various reagents, without damage due to chemical corrosion.
Biopharmaceutical Research Institution: Conducts drug development and biological product research, requiring standardized handling of various biological material waste generated during the experimental process. Biohazard symbol thickened medical bags provide professional waste management solutions, complying with GLP and GMP requirements.

Usage Steps

Choose Appropriate Specifications: Based on the type and quantity of laboratory waste, select the appropriate size of laboratory medical bag, with common specifications including 45×55cm, 60×80cm, 70×90cm, etc.
Check Confirmation: Check if the bag body is intact, if the biohazard symbols are clear, if the heat-sealed edges are firm, ensuring compliance with usage standards before use.
Correct Installation: Place the medical bag on a dedicated waste container, fold the bag opening outward covering the container edge by at least 10cm, ensuring stability without slipping, preferably choosing a container with a lid design.
Standard Disposal: According to laboratory waste management procedures, put biohazardous waste into the bag, sharp objects should first be placed in dedicated sharps containers, liquid should be sealed or absorbed before disposal, not exceeding 2/3 of the bag's capacity.
Safe Sealing: When the waste reaches an appropriate amount, operate within a biosafety cabinet or fume hood, carefully lift the bag opening, avoiding squeezing the air inside the bag, use the provided high-strength ties to tightly seal at a position 8cm from the bag opening.
Secondary Protection: For high-risk biological waste, it is recommended to use double-layer packaging, first packaging with one bag, then placing it in a second bag, forming a double barrier, both layers requiring clear marking.
Complete Marking: Fill in laboratory name, date, waste type, hazard level, responsible person, and other information in the designated area of the bag, ensuring waste traceability management.
Standard Disposal: Place the sealed waste bags in dedicated biohazard waste containers, handling according to laboratory biosafety management regulations, either inactivating or directly handing over to professional institutions for processing.

Color/Style Display

Orange-Yellow Standard Version: Complying with international biohazard warning color standards, with conspicuous orange-yellow background paired with black biohazard symbols, used to collect general biohazardous waste, suitable for most laboratories.

Maintenance Guide

Storage Conditions: Store in a dry, well-ventilated, and shaded environment, temperature controlled between -20°C to 50°C, relative humidity not exceeding 80%, away from heat sources, fire sources, and direct sunlight.
Protection Requirements: The storage area should be set up independently, avoiding storage with chemicals and sharp objects, preferably equipped with moisture-proof facilities and fire-fighting equipment, with regular disinfection to reduce contamination risk.
Shelf Life: Under recommended storage conditions, unopened products have a shelf life of 48 months, and opened products should be used within 24 months, exceeding the shelf life may affect barrier performance.
Inventory Management: Laboratories should establish a medical bag usage registration system, recording batch numbers and usage situations, implementing a first-in-first-out principle, regularly checking inventory quality, replacing problematic items promptly.
Emergency Plan: Develop a laboratory waste leakage emergency handling plan, equip spare medical bags, disinfectants, personal protective equipment, and other emergency supplies, ensuring prompt and effective handling in case of accidents.
