The four handle scientific layout is the pinnacle of mechanical design for this corpse bag. The double or single handle design of traditional corpse bags can easily cause the bag to tear or the body to slip off due to uneven force when transporting heavy corpses, posing great difficulties and risks to the handlers. The four handle thickened corpse bag innovatively adopts a handle design with symmetrical distribution at four corners, as if building a stable "mechanical framework" for corpse transportation. When four staff members each hold one handle, the force can be evenly distributed to the four key support points of the bag, forming a perfect balance state. In actual rescue scenarios, the four handle design demonstrates astonishing stability when facing the bodies of heavier victims buried due to landslides. During the transportation process, the bag remained flat without any distortion or deformation, and the success rate of a single transportation was increased by more than 40% compared to traditional designs. This not only greatly shortens the rescue time, but also ensures the integrity and dignity of the body during the transportation process, allowing every life to be properly placed in the final journey. Protective Fortress: Thickened Materials Build Safe 'Copper and Iron Walls' The thickened material process endows the four handle corpse bag with unparalleled protective performance. High strength and high-density polyethylene (HDPE) and polypropylene (PP) composite materials are selected, and double-layer composite thickening technology is used to achieve industry-leading bag thickness. This thickened design is like creating a sturdy "protective fortress" for the body, which can effectively resist various external threats. Excellent sealing performance is the core advantage of the four handle thick corpse bag in terms of hygiene protection. When handling infectious disease remains or storing them in special environments, tight sealing performance is the key to blocking the spread of viruses and bacteria and preventing odor leakage. This corpse bag adopts industry-leading multiple sealing technology, building an indestructible hygiene "absolute defense line". The bag opening is equipped with a high-precision and high-strength zipper system, with tightly interlocked zipper teeth. After thousands of pull and close tests, it remains smooth and unobstructed, ensuring a flawless sealing effect. At the same time, a hot melt sealing strip is added on the outside of the zipper, which achieves seamless connection by melting the bag material at high temperature, further enhancing the sealing performance. In addition, the sealing strips around the bag body are made with a special formula, which has good elasticity and viscosity, and can tightly adhere to the edges of the bag body, effectively preventing liquid leakage and odor emission. The strong durability makes the four handle thick corpse bag an "environmental conqueror" that adapts to various extreme environments. Whether in high-temperature and scorching desert areas, cold and frozen polar regions, or industrial accident sites with severe chemical pollution, this body bag can always maintain stable performance and provide reliable support for body handling. The thickened material has excellent anti-aging and UV resistance. When exposed to the sun for a long time outdoors, the bag body will not appear embrittlement, discoloration and other phenomena, and the physical performance is still good. At the same time, it also has the characteristics of acid and alkali resistance and corrosion resistance, which can resist the erosion of various chemical substances. In chemical leakage accidents, when faced with corrosive substances such as strong acids and alkalis, the four thick body bags can still remain intact, ensuring the safe transportation of the body. In addition, the durability of the corpse bag is also reflected in its reusability. After professional cleaning and disinfection, it can be used multiple times for body treatment, greatly reducing the cost of use. Through actual testing, under normal use and maintenance, the service life of this corpse bag can reach more than three times that of ordinary products, truly achieving a perfect combination of economic practicality and high performance. The four handle thick corpse bag has become an all-around guardian in the fields of funeral services and emergency rescue due to its mechanical design stability, protective material technology, excellent sealing technology, adaptability of durability, and humanized operation design. It is not only a manifestation of respect and reverence for life, but also a perfect fusion of professional spirit and technological power, providing the most solid and warm guarantee for the final journey of every life.
