Material and Process Details

Made of high-strength medical-grade polymer material, with main components being specially modified high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE), adding special enhancers and anti-chemical corrosion agents. The material thickness is precisely controlled at 0.08±0.002mm, far exceeding the thickness of ordinary laboratory waste bags, providing more reliable physical protection.

The product is manufactured using advanced three-layer co-extrusion technology, forming a multi-layer functional structure: the outer layer is high-strength HDPE, providing basic mechanical strength and chemical stability; the middle layer is a special barrier layer, adding nano-level barrier materials, significantly enhancing anti-penetration performance; the inner layer is modified LLDPE, with good flexibility and chemical resistance, resistant to common laboratory chemicals and disinfectants.

The biosafety performance is achieved through multiple designs, the material passing ASTM F1671 viral penetration testing, effectively blocking microorganism particles as small as 27nm in diameter. Leak-proof rate as high as 99.9%, no leakage in 60-minute liquid penetration testing under 65kPa pressure (approximately 6.5 meters of water column pressure), providing reliable biosafety barriers.

The puncture resistance is enhanced through special "grid reinforcement" technology, forming microscopic grid structures in the material, significantly enhancing anti-puncture performance. Puncture resistance ≥400g, passing ASTM F1342 puncture testing, effectively preventing laboratory sharp waste (such as broken glassware, blades, etc.) from penetrating the bag.

The bag heat-sealing adopts high-precision ultrasonic heat-sealing technology, with a heat-sealing width of 12mm, heat-sealing temperature precisely controlled at 190±2°C, pressure 0.65MPa, forming a firm seal with a strength of 22N/15mm. The bag bottom corner design is specially reinforced, adopting "trapezoidal reinforcement" structure, corner strength improved by 60%, solving the problem of laboratory waste bags most easily damaged at the corners.

The biohazard symbol is printed using chemical corrosion-resistant ink, complying with FDA indirect food contact material standards, free from heavy metals and harmful substances. The symbol design complies with ISO 7010 and WHO biosafety standards, including internationally recognized biohazard symbols and "Biohazardous Waste" Chinese-English bilingual warning text, symbol size of 12×12cm, maintaining high identifiability under various lighting conditions in laboratories.

The product is produced in a class 10,000 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, tensile strength testing, puncture resistance testing, chemical stability testing, and viral penetration testing, ensuring stable and reliable product performance, meeting laboratory biosafety requirements.

Usage Steps

Preparation Work: Before starting experiments, place the red laboratory specialized bag in a convenient position, ensure the bag is intact, symbols clearly visible.
Correct Unfolding: Gently unfold the specialized bag, being careful not to use excessive force causing static electricity or bag damage, reserving enough space for waste collection.
Safe Installation: Based on laboratory settings, can fold the bag opening outward and place on dedicated waste containers, ensuring stability without slipping, bag opening exposed about 15cm, facilitating subsequent sealing.
Standard Disposal: According to laboratory waste management procedures, put biohazardous waste, injurious waste, or chemical contaminants into red specialized bags, note to control the amount not exceeding 2/3 of the bag's capacity, reserving enough space for safe sealing.
Avoid Sharp Objects: Do not directly place sharp objects (such as needles, slides, broken glass, etc.) into specialized bags, should first place in puncture-resistant sharps containers, then place the sealed sharps containers into red specialized bags, preventing sharp objects from penetrating the bag.
Chemical Treatment: For high-risk biological waste, appropriate chemical disinfection can be performed before sealing according to laboratory procedures, such as adding appropriate amounts of bleach or other approved disinfectants.
Safe Sealing: When the waste reaches an appropriate amount, carefully lift the bag opening, avoiding touching internal waste, use high-strength ties to tightly seal at a position 10cm from the bag opening, ensuring firm sealing. For double sealing design versions, first tighten the top sealing rope and tie a knot, then use ties to close, forming double protection.
Information Marking: Mark laboratory name, date, waste type, responsible person, and other information in the designated area of the bag using waterproof marker, facilitating traceability management, ensuring information is clear and identifiable.
Correct Storage: Place the sealed laboratory waste bags in the designated biohazardous waste temporary storage area, following laboratory waste management procedures, waiting for centralized processing by professional personnel. Do not mix with ordinary waste, avoiding cross-contamination.
