Fully Biodegradable Flat-Mouth Garbage Bags Suppliers

Product structure and material technology: a balance between environmental performance and practicality
Taizhou Huangyan Zeyu New Material Technology Co., Ltd., as a leading domestic biodegradable new material research and development and production enterprise, has long been committed to applying sustainable material technology to consumer goods. Its fully biodegradable flat-mouth garbage bags has demonstrated a high degree of professionalism and foresight in terms of product structure, material selection and production process.
The "flat-mouth" structure refers to the design of eight equidistant folding lines on the bag body by machine in the garbage bag making process, so that the bag has a larger internal volume and better three-dimensional structural support after unfolding. This structure can enhance the capacity without increasing the cost of raw materials. Traditional flat bags or round-bottom bags are prone to forming "dead corners" when loading garbage due to bulging at the bottom and the inability to open the two sides, and the actual loading volume is far lower than the theoretical volume. The fully biodegradable flat-mouth garbage bags is unfolded through structural guidance, effectively utilizing every inch of space, allowing users to load more garbage with the same bag size.
The unfolded eight-fold structure enhances the three-dimensional sense and shape stability of the bag body, and it is not easy to "collapse" or shrink the bag mouth due to excessive or heavy objects, so that the bag can be naturally stretched in the trash can, which is convenient for garbage placement and replacement. It is especially suitable for scenes such as kitchens, offices, and commercial areas where garbage bags need to be frequently replaced.
Compared with the common vest bag or drawstring bag design, the flat-mouth garbage bag has a simpler structure, more intuitive use, and has great advantages in environmental protection and material saving. Although the traditional vest bag is easy to carry, it has a small opening and limited opening, which is easy to spill, especially when handling large pieces of garbage or liquid garbage. The flat bag has a wider and neater cross-section of the bag opening, which provides more operating space when placing garbage and has higher efficiency. Since the bag opening has no fixed shape or handle restrictions, the flat-mouth design can be adapted to various types of trash cans, including square, round, rectangular openings, etc., regardless of size, and users are easier to buy and replace.
In the process of garbage disposal, the closing method of the bag mouth directly affects the sealing, hygiene and convenience of the garbage. The flat-mouth 20%-off garbage bag provides a highly free sealing option, and users can flexibly handle it according to their own scenarios.

Material compounding advantages: PBAT+PLA+starch-based synergistic degradation system
In terms of raw materials, Zeyu New Materials uses polybutylene adipate/terephthalate, polylactic acid and bio-based starch to compound three materials to build a comprehensive material system that is both strong and heat-resistant, and has rapid degradation capabilities:
PBAT provides toughness and elasticity, so that the garbage bag has excellent tensile and load-bearing capacity, and can carry wet heavy garbage or sharp objects without being easily torn;
PLA provides structural rigidity and thermal stability, ensuring that the bag remains stiff and does not deform in high-temperature garbage bins or hot weather;
Starch-based materials accelerate the degradation process, enhance the reaction affinity with microorganisms, and make the bag decompose into harmless substances faster under soil or composting conditions.
Through advanced blending technology and modification treatment, the three materials are fused to reinforce each other, overcoming the shortcomings of previous single biodegradable materials in certain performances, so that the product has degradability, mechanical strength and cost adaptability at the same time.
Zeyu New Materials has an independent and complete R&D system, equipped with advanced film blowing production lines and quality inspection equipment, and has passed GB/T19001-2016 and ISO9001:2015 quality management system certification. It strictly controls from material ratio to finished product delivery to ensure product batch stability and market delivery capabilities.
The company maintains a stable industry-university-research cooperation relationship with many universities and research institutions, and continues to promote the optimization of material degradation performance and the innovation of new environmentally friendly structures, providing customers with product solutions with greater technical depth and market competitiveness.

Multi-scenario adaptation
Against the background of the "dual carbon" strategy and increasingly stringent environmental regulations, the fully biodegradable garbage bag market is ushering in a period of rapid expansion. In particular, daily life garbage management, as one of the most widely used areas for plastic bags, is a key breakthrough in achieving large-scale replacement applications of degradable materials.
The fully biodegradable flat-mouth 20% off garbage bags launched by Zeyu have been widely used in the following scenarios:
Home kitchens and bathrooms: The bags have excellent impermeability and sealing properties, suitable for daily treatment of wet garbage and odorous garbage;
Office areas: Loading dry garbage such as waste paper, plastic film, beverage cups, high strength and no cracking;
Commercial places: Garbage collection in public areas such as supermarkets, cafes, hotels, etc., which is environmentally friendly and easier to build brand image;
Government and environmental protection project support: Environmentally friendly streets, park renovations, and urban composting pilot projects have gradually adopted fully degradable garbage bags as standard configurations.
Many provinces and cities in my country have issued policies to restrict or prohibit the use of non-degradable plastic bags, while providing subsidies or tax incentives for degradable plastics. The increase in public environmental awareness has also prompted end consumers to be willing to pay for green products.
According to the "2024 China Degradable Plastics Industry Research Report", the domestic fully biodegradable garbage bag market size will maintain a compound growth rate of more than 20% in the next five years, and the market size is expected to exceed 20 billion yuan by 2028.
Zeyu New Materials' fully biodegradable products have international certification support and have been successfully exported to Europe, Southeast Asia, the Middle East and other regions. In Europe and the United States, countries with extremely high environmental standards, biodegradable garbage bags have become "standard products" in the purchase lists of large supermarkets and public institutions. With high performance and high degradation rate, Zeyu products have the hard power to compete with major international brands.
