Material and Process Details

Made of medical-grade polymer material, with low-density polyethylene (LDPE) and high-density polyethylene (HDPE) as main components, adding special barrier agents and enhancers. The material thickness is precisely controlled at 0.075±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 three-layer co-extrusion technology, forming a multi-layer protective structure: the outer layer is high-strength HDPE, providing basic mechanical strength and rigidity; the middle layer is a special barrier layer, adding nano-level biological barrier enhancers, significantly enhancing penetration prevention performance; the inner layer is soft LDPE, with good extensibility and sealing properties. The three layers are perfectly combined through precision thermal fusion technology, with no risk of layer separation.

The anti-biohazard performance is achieved through a special barrier layer, adding "maze-like" microscopic structures in the middle layer, effectively blocking microorganism particles as small as 27nm from penetrating. This design is verified by ASTM F1671 viral penetration testing, effectively blocking Phi-X174 bacteriophage (diameter approximately 27nm, smaller than most viruses) under 60kPa pressure.

The bag heat-sealing adopts high-precision ultrasonic heat-sealing technology, with a heat-sealing width of 10mm, heat-sealing temperature precisely controlled at 185±2°C, pressure 0.62MPa, forming a firm seal with a strength of 18N/15mm. At the same time, the bag bottom corners undergo special reinforcement treatment, adopting "arc transition" design, eliminating stress concentration points, improving corner strength by 50%, solving the problem of traditional medical waste bags easily breaking from bottom corners.

The biohazard symbol is printed using specially formulated ink, complying with FDA indirect food contact material standards, free from heavy metals and harmful substances, resistant to disinfectant corrosion. The symbol size is 12×12cm, 50% larger than standard requirements, maintaining good identifiability under various lighting conditions.

The product is produced in a class 100,000 clean room, with fully automated process, reducing the risk of human contamination. Each batch of products undergoes strict quality control testing, including thickness uniformity testing, penetration prevention testing, tensile strength testing, heat-sealing strength testing, and drop testing, ensuring stable and reliable product performance.

Color/Style Display

Standard Yellow Version: Standard yellow (PMS 109C) complying with GB 19217-2011 regulations, printed with black biohazard symbols and "Infectious Waste" warning text, the most basic style commonly used in hospitals.
Special Red Version: Bright red warning, printed with sharp object warning symbols and "Injurious Waste" warning text, specially designed for secondary packaging of sharps containers, providing an extra safety protection layer.
Transparent Bottom Yellow Bag Version: Innovative design, with the lower half of the bag using transparent material, while the upper half maintains yellow warning area, facilitating medical staff observation of contents, confirming waste type and volume.

Application Scenarios

Hospital Operating Room: The surgical process generates a large amount of medical waste, 70×90cm large capacity anti-biohazard bags can collect waste generated from an entire operation at once, with a capacity of approximately 110L, sufficient to accommodate various dressings, disposable surgical supplies, and materials contaminated with body fluids, reducing replacement frequency, improving work efficiency.
Isolation Ward: Treats infectious disease patients, generating high-risk medical waste, the high penetration prevention rate (99.9%) of anti-biohazard bags ensures pathogens do not spread, ensuring the safety of medical staff and the environment, meeting the strict requirements of infectious disease prevention and control.
Hospital Laboratory Department: Handles various samples and waste potentially containing pathogens, anti-biohazard bags provide reliable biological barriers, preventing laboratory waste liquid leakage and aerosol diffusion, meeting laboratory biosafety management specifications.
Medical Waste Temporary Storage Room: Medical waste needs temporary storage before final disposal, the premium material and reinforced heat-sealing of large capacity anti-biohazard bags ensure no easy damage during stacking, preventing cross-contamination between different batches of waste.
Fever Clinic: Screens potential infectious disease patients, generating medical waste with infection risks, standardized biohazard symbols remind staff to handle with care, anti-biohazard design providing support for epidemic prevention and control.

Usage Steps

Take Out and Check: Take out an anti-biohazard bag from the packaging, confirm the bag body is intact, symbols are clear, with no damage or poor heat-sealing.
Correct Unfolding: Gently shake the bag to completely unfold it, avoid using excessive force causing static electricity or bag damage.
Appropriate Installation: Place the bag on a medical waste container, fold the bag opening outward covering the container edge by about 10-15cm, ensuring stability without slipping.
Standard Disposal: According to medical waste classification management requirements, put the corresponding category of medical waste into the bag, not exceeding 3/4 of the bag's capacity, reserving enough space for safe sealing.
Avoid Sharp Objects: Do not directly place sharp objects (such as needles, blades, etc.) into the bag, should first place in dedicated sharps containers, then place the sharps containers into the anti-biohazard bag.
Safe Sealing: When the waste reaches an appropriate amount, carefully lift the bag opening, avoiding touching internal waste, use ties to tightly seal at a position 8-10cm from the bag opening, ensuring firm sealing.
Information Marking: Mark department, date, waste type, responsible person, and other information in the designated area of the bag using a marker, facilitating traceability management.
Correct Transfer: Grab the upper safe area of the bag for carrying, avoid the bag being close to the body, handle with care, preventing squeezing or collisions causing damage.
Standard Storage: Place the sealed medical waste bags in the designated medical waste temporary storage area, stored according to classification requirements, waiting for centralized processing by professional personnel.

Maintenance Guide

Storage Conditions: Store in a dry, well-ventilated, and shaded environment, temperature controlled between 5-35°C, relative humidity not exceeding 75%, avoiding direct sunlight and high-temperature environments, preventing material aging.
Protection Measures: The storage area should be away from heat sources, fire sources, and chemicals, avoiding contact with sharp objects, preferably equipped with dedicated medical waste bag storage racks or containers, reducing the risk of accidental damage.
Shelf Life: Under recommended storage conditions, unopened products have a shelf life of 36 months, and opened products should be used within 24 months, exceeding the limit may affect anti-biohazard performance.
Batch Management: Medical institutions should establish an anti-biohazard bag usage registration system, recording batch numbers and usage situations, adopt a "first-in-first-out" principle for inventory management, avoiding performance degradation due to long-term storage.
Emergency Handling: If bag damage is found during use, immediately completely wrap the damaged bag with another intact anti-biohazard bag, and appropriately disinfect the leakage area.
