Material and Process Details

Made of medical-grade high-density polyethylene (HDPE) material, with a density of 0.96g/cm³, specific gravity higher than water, featuring excellent chemical stability and mechanical strength. The raw material undergoes special formula modification, adding anti-UV agents and antioxidants, enhancing material stability in laboratory environments. The material has passed FDA indirect food contact material standards and USP Class VI biocompatibility testing, ensuring safety and non-toxicity.

The product is manufactured using advanced biaxial orientation technology (BOPE), precisely stretched in both longitudinal and transverse directions, making molecular chains highly oriented and arranged, forming a denser structure. The thickness is precisely controlled at 0.075±0.003mm, far exceeding national standard requirements, providing more reliable physical protection. Specially adopting double-layer structure design at the bag bottom, with a total thickness of 0.15mm, providing double assurance for liquid waste.

The bag adopts innovative "double-bottom" structure, with inner and outer layers separately heat-sealed, heat-sealing widths of 10mm and 12mm respectively, forming staggered sealing areas. The outer layer heat-sealing temperature is 190±2°C, inner layer heat-sealing temperature is 185±2°C, both with pressure of 0.65MPa, forming a firm seal with a strength of 22N/15mm, 2 times that of ordinary heat-sealing.

The product has undergone strict chemical compatibility testing, able to withstand common laboratory chemicals, including: acids (concentration ≤30%), bases (concentration ≤20%), alcohols (ethanol, methanol, etc.), formaldehyde (concentration ≤10%), glutaraldehyde (concentration ≤2%), etc. After 24-hour exposure to these chemicals, material strength retention rate ≥90%, ensuring safe and reliable use in laboratory environments.

The bag printing uses special chemical corrosion-resistant ink, complying with RoHS environmental standards, with high printing firmness, remaining clearly identifiable after contact with common laboratory solvents. The symbol design complies with international biosafety standards, including biohazard symbols and "Laboratory Medical Waste" warning text, with conspicuousness 45% higher than ordinary medical waste bags.

Each batch of products undergoes strict quality control testing, including thickness uniformity testing, tensile strength testing, liquid penetration testing, viral penetration testing, and chemical compatibility testing, ensuring stable and reliable performance, meeting the stringent requirements of laboratories.

Color/Style Display

Standard Yellow Version: Yellow complying with international biosafety standards, printed with conspicuous biohazard symbols and "Laboratory Medical Waste" warning text, the most basic style commonly used in laboratories.
Transparent Bottom Observation Version: Innovative design, with the lower half of the bag using transparent high-density material, while the upper half maintains yellow warning area, facilitating laboratory personnel observation of contents, particularly suitable for experimental scenarios requiring confirmation of waste types.
Enhanced Anti-Chemical Version: On the basis of standard anti-leakage, adding special chemical-resistant coating, resistance enhanced to a broader spectrum of laboratory chemicals, including organic solvents (toluene, xylene, etc.) and higher concentrations of acids and bases, suitable for chemical laboratories.

Application Scenarios

PCR Laboratory: Conducts nucleic acid amplification and detection, generating waste liquid containing nucleic acids and primers, high-density HDPE material anti-leakage medical waste bags can completely seal these waste liquids, leak-proof rate of 99.95% ensuring no contamination of the experimental environment, avoiding false positives and cross-contamination.
Microbiology Laboratory: Cultivates and studies various microorganisms, generating waste with biosafety risks, laboratory medical waste bags passing ASTM F1671 viral penetration testing, effectively blocking pathogen spread, ensuring laboratory personnel safety and environmental hygiene.
Pathology Laboratory: Handles tissue samples and fixatives, generating waste containing chemicals such as formaldehyde and xylene, high-density material medical waste bags with excellent chemical stability, safely collecting these chemical wastes, preventing harmful substance evaporation and leakage.
Laboratory Department Laboratory: Analyzes various clinical samples, generating waste containing blood, body fluids, etc., double-bottom design and thickened protection ensuring no leakage even with liquid concentrated at the bag bottom, maintaining a clean experimental environment, reducing biological contamination risk.
BSL-2/BSL-3 Laboratory: Operates with medium-risk or high-risk pathogens, with strict requirements for waste handling, medical waste bags passing WHO laboratory biosafety assessment providing compliance assurance, meeting the strict standards of biosafety laboratories.

Usage Steps

Choose Appropriate Specification: Based on laboratory waste type and quantity, select appropriate specification laboratory medical waste bags, common specifications include 40×50cm (small), 55×70cm (medium), 70×90cm (large).
Pre-Use Check: Check if the bag body is intact before use, ensuring no damage, pinholes, or poor heat-sealing, to avoid affecting anti-leakage performance.
Correct Unfolding: Gently shake the medical waste bag to completely unfold it, note gentle movements, avoiding generating airflow causing laboratory contamination material spread.
Appropriate Installation: Place the medical waste bag on a laboratory waste container, fold the bag opening outward covering the container edge by about 12-15cm, ensuring stability without slipping.
Standard Disposal: According to laboratory waste management procedures, put the corresponding category of waste into the bag, liquid waste should be controlled within 1/3 of the total capacity, avoiding excessive weight causing too much pressure at the bottom.
Avoid Sharp Objects: Do not directly place glass fragments, needles, and other sharp objects, should first place in dedicated sharps containers, then place the sharps containers into the medical waste bag, preventing puncture.
Chemical Compatibility Check: Before placing special chemical waste, consult the chemical compatibility table, confirming the medical waste bag material can withstand that chemical, use enhanced anti-chemical version if necessary.
Safe Sealing: When the waste reaches an appropriate amount (not exceeding 2/3 of the bag's capacity), carefully lift the bag opening, avoiding touching internal waste, use high-strength ties to tightly seal at a position 10cm from the bag opening.
Double Sealing: For waste with more liquid or higher risk, it is recommended to use double ties, tying again at a position 5cm above the first tie, forming double sealing, further enhancing safety.
Correct Marking: Use waterproof marker to mark laboratory name, date, waste type, responsible person, and other information in the designated area of the bag, ensuring waste traceability management.

Maintenance Guide

Storage Conditions: Store in a dry, well-ventilated, and shaded environment, temperature controlled between -5~40°C, relative humidity not exceeding 80%, avoiding direct sunlight and high-temperature environments, preventing material aging.
Chemical Environment Precautions: The storage area should be away from volatile chemicals and strong oxidizers, avoiding long-term exposure to organic solvent vapors, to prevent affecting material performance.
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 limit may affect anti-leakage performance and material strength.
Regular Inspection: Laboratories should regularly sample and inspect the performance of inventory medical waste bags, can evaluate anti-leakage function through simple water testing (filling with appropriate amount of water and observing if there is leakage), ensuring safe and reliable use.
Emergency Handling: Develop laboratory waste leakage emergency handling plan, equip spare medical waste bags, absorbent materials, disinfectants, and other emergency supplies, regularly train laboratory personnel, ensuring prompt and effective handling in case of accidents.
