PRODUCTS FAQ

Our eco-bags are available in a diverse range of sizes, which are specifically designed to cater to the varying requirements of different industries such as households, industries, and supermarkets. For household use, we offer small-sized eco-bags. These are generally around 20 - 30 cm in width and 30 - 40 cm in height. They are highly convenient for daily tasks like carrying a few groceries from the local store, a small book for leisure reading, or personal essentials like a wallet and a mobile phone. Medium-sized eco-bags, with a width of approximately 30 - 40 cm and a height of 40 - 50 cm, are suitable for both household and light industrial applications. In households, they can hold a couple of clothing items for a short outing or a laptop for work or study. In industrial settings, they can be used to transport small tools or samples. When it comes to supermarkets and industrial applications that demand larger capacity, our large-sized eco-bags are the ideal choice. These typically measure about 40 - 50 cm in width and 50 - 60 cm in height. Supermarkets can utilize them for customers' bulk shopping, while industries can use them to carry heavier and bulkier items such as sports equipment for sports goods manufacturing or for packing materials during a short industrial trip or delivery.

Biodegradable materials are designed to break down naturally over time through the action of microorganisms, fungi, or other biological means. This process typically occurs under specific environmental conditions such as in compost heaps or soil. For example, some biodegradable plastics are made from plant-based polymers like polylactic acid (PLA), which can decompose into carbon dioxide, water, and biomass, reducing the long-term environmental impact compared to traditional plastics.Compostable materials take biodegradability a step further. They not only break down but also can be composted, which means they can turn into nutrient-rich compost that can be used to fertilize soil and support plant growth. Materials like certain types of paper and some bio-based plastics can be composted in industrial composting facilities or in home compost piles if they meet the right criteria. Recyclable materials, on the other hand, can be processed and reused to make new products. For instance, recyclable plastics can be melted down and molded into new plastic items, reducing the need for virgin plastic production and conserving resources. Metals and some types of fabric used in the custom bags may also be recyclable. This gives you the option to choose a material that suits your specific needs and environmental priorities, whether it's minimizing waste, promoting composting, or enabling recycling.

During the raw material procurement process, we have established an extremely strict supplier screening mechanism and only cooperate with suppliers who have an excellent reputation in the industry and can continuously and stably supply high-quality biodegradable raw materials. The selected raw materials must not only fully comply with international authoritative quality and environmental protection standards, such as the composition and performance specifications clearly defined by certification systems like EN13432 and BPI, but also each batch of raw materials has to undergo multiple meticulous inspection procedures before entering the factory. This includes accurate composition analysis, comprehensive physical performance testing, etc. Only raw materials with completely satisfactory inspection results can enter the production process.In the production process, we are equipped with advanced automatic production equipment and have assembled a professional and experienced technical team. To ensure the accuracy and stability of the production process, all production equipment is meticulously maintained and accurately calibrated according to a predetermined schedule. From the precise mixing ratio of raw materials to the perfect forming and clear printing of packaging bags, we have set strict and scientific quality control points for each process. By combining online monitoring and sampling inspection, we conduct real-time and dynamic monitoring of key physical indicators such as product thickness, strength, and dimensional accuracy, and firmly ensure that each production link closely adheres to the preset high-quality standards.In terms of finished product inspection, we implement a comprehensive and rigorous multi-dimensional inspection procedure. In addition to conducting a comprehensive and meticulous inspection of the product's appearance to ensure that there are no flaws and the printing is clear, complete, and with uniform colors, we also use professional simulation testing equipment to deeply verify the degradation performance of the product, simulating whether it can be effectively degraded in the expected time period and ideal degradation mode under different natural environmental conditions (such as different temperatures, humidity, soil types, etc.). At the same time, according to relevant international and domestic standards, advanced testing instruments are used to conduct sampling inspections of the product's physical properties, such as strict mechanical property tests such as tensile strength and tear strength. Only when all inspection items are flawlessly qualified can the finished products be allowed to be packaged and shipped.In addition, we have carefully constructed a complete and efficient quality traceability system. From the detailed batch information of raw material procurement, to the accurate records of production processes, and then to the detailed reports of finished product inspection, the information generated in each link is recorded in full and can be conveniently and quickly queried through a dedicated traceability system. Once any quality problem occurs, with the help of this powerful traceability system, we can quickly and accurately locate the root cause of the problem in a very short time and take corresponding corrective and preventive measures in a timely and decisive manner to effectively ensure the continuous stability and reliability of product quality and maximize customer satisfaction and trust.
