Qingdao Mobile Toilet Packing Bags
The packing bags used in Qingdao's mobile toilets are made of biodegradable film and are a core component of waterless, packing-type eco-friendly toilet fixtures. The following provides an explanation from three aspects: technical principles, product characteristics, and market supply.

1. Technical Principles and Functional Implementation
The waterless, packing-type toilet fixtures used in Qingdao's mobile toilets achieve waterless fecal treatment through mechanical transmission devices. When a user steps on the transmission rod, the mechanical structure automatically pulls the packing bag made of biodegradable film downward, wrapping the feces and moving it into the fecal storage tank. Simultaneously, the packing bag on the squatting surface is updated synchronously, forming a new isolation layer. During this process, the sealing device effectively prevents odor leakage through physical sealing, ensuring the hygiene of the usage environment. The entire system does not require water resources and relies solely on the replacement of packing bags to complete fecal collection, making it suitable for water-scarce areas or temporary public places.
2. Environmental Characteristics of the Packing Bags
The core material of the packing bags is biodegradable film, typically made from polylactic acid (PLA), starch-based biodegradable materials, or photodegradable plastics. These materials can gradually degrade in the natural environment through microbial decomposition, photoxidation, or hydrolysis, ultimately transforming into carbon dioxide, water, and inorganic salts, significantly reducing the long-term pollution risk of traditional plastic bags to soil and water bodies. Additionally, the thickness and toughness of the packing bags are optimized to withstand the weight of feces while allowing for smooth breakage and renewal under mechanical traction, avoiding residue or breakage issues.
3. Market Supply and Product Specifications
Currently, there are packing bag products specifically designed for mobile toilets available on the market, such as a brand's "Waterless Scenic Area Eco-Friendly Degradable Toilet Fecal Packing Device for Squat and Sit Toilets Plastic Bags." According to price information updated on May 15, 2026, the minimum order quantity for this product is 1 roll, with a unit price of 202.00 yuan per roll. These packing bags are usually packaged in rolls, with each roll containing hundreds of individual packing bags, with the specific quantity varying by specification. The products have wide adaptability and are compatible with both squat-type and sit-type mobile toilets, and support customized sizes to meet the needs of different toilet fixture models.
Summary: The packing bags for Qingdao's mobile toilets use biodegradable materials as their core, achieving waterless fecal collection and sealing through mechanical transmission, combining environmental friendliness with practicality. Related products on the market have standardized supply, providing key consumables support for the popularization of mobile toilets.
