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.

Our company supports the following six payment methods:T/T It's a direct bank transfer. The importer remits the money to the exporter through the bank. It's divided into front T/T and back T/T. Before T/T, the importer pays first, and the exporter delivers the goods, which has lower risk to the exporter. After T/T, the exporter first delivers the goods, and the importer pays after receiving the goods. The exporter may face a certain risk of collection, but this method is more beneficial to the importer. L/C A conditional payment promise made by a bank acting as an intermediary. The importer applies to the bank and the bank notifies the exporter after examination. The exporter delivers the goods according to the terms of the L/C and presents the documents. The bank will pay as long as the documents meet the requirements. This method has certain guarantees for both sides, but the procedures are relatively complex and the cost is high. Collection This includes documents against payment (D/P) and documents against acceptance (D/A). D/P means that the importer can only get the shipping documents after payment. D/A means that the importer can obtain the documents after accepting the bill of exchange, the former risk is relatively small. Collection depends on the commercial credit of the importer, and the bank only assists in collection. Escrow It is an online payment guarantee service. The buyer first pays to the third-party platform, and after confirming the receipt of the goods, the money will be transferred to the seller, which protects the interests of both buyers and sellers, and is suitable for cross-border e-commerce small transactions. Western Union Money can be quickly transferred, generally after the buyer pays, the seller relies on the remittance monitoring number and other information to withdraw money. Its advantage is that it is fast, but the cost may be higher, and there is a certain limit on the transaction amount, which is suitable for small emergency remittances. PayPal It is a world-renowned online payment platform. The buyer pays through a PayPal account, and the seller can withdraw the money after receiving it. It is convenient and fast, but there are risks of account freezing and higher fees, and it is often used for cross-border e-commerce transactions.

We accept any form of packaging, which gives our clients a wide range of options to best suit their specific needs and the nature of their products. Card Head Bag The card head bag is a popular choice for many. It combines the functionality of a bag with the sturdiness of a cardstock header. This header can be printed with detailed product information, brand logos, and attractive graphics, making it excellent for retail display purposes. It's often used for items like small accessories, handicrafts, or even food products in a smaller quantity. The bag part provides convenient storage and easy access for consumers, while the cardstock header adds a touch of professionalism and helps in product identification at a glance. Paper Box Paper boxes are highly versatile and offer great protection for the contents inside. They can be customized in various shapes, sizes, and designs. For delicate items such as electronics, glassware, or high-end cosmetics, paper boxes with appropriate cushioning materials can safeguard the products from impacts during transportation and handling. Additionally, they can be beautifully decorated with embossing, foil stamping, or colorful printing to enhance the brand image and create an appealing unboxing experience for customers, which is especially important in the e-commerce industry where the first impression matters a lot. Colored Paper Coloured paper is not just about adding a visual appeal but also serves practical purposes. It can be used as wrapping paper to give a simple yet charming look to gifts or individual products. It's available in a vast array of colors and textures, allowing for creative and customized packaging solutions. For example, during festive seasons, using coloured paper with corresponding holiday-themed prints can make the products stand out on the shelves and create a festive atmosphere for the consumers. Moreover, coloured paper can also be used as an inner lining in boxes or bags to add an extra layer of protection and a pop of color. Vacuum Formed Packaging Vacuum formed packaging is ideal for products that need to be protected from moisture, air, or other environmental factors. It involves creating a custom-shaped plastic mold that tightly conforms to the product's shape once the air is removed. This packaging method is commonly used for food items like meats, cheeses, and processed foods to extend their shelf life by reducing oxygen exposure. It's also utilized for industrial parts or electronic components to keep them free from dust and contaminants, ensuring their quality and functionality remain intact during storage and transportation. Self-Adhesive Bag Self-adhesive bags are extremely convenient and user-friendly. They usually come with an adhesive strip that allows for easy sealing, which is very handy for packaging small items like stationery, jewelry, or samples. The transparency of many self-adhesive bags enables the contents to be clearly visible, which is beneficial for both inventory management and customer inspection. They can also be customized with printed labels or logos on the front, adding a branded touch to the packaging while maintaining its simplicity and ease of use. Shrink Film Shrink film is a cost-effective packaging solution that offers excellent protection and a professional look. When heat is applied, the film shrinks tightly around the product, creating a snug and secure wrap. It's widely used for bundling multiple items together, like sets of books, toys, or beverage bottles. It not only keeps the products in place but also acts as a barrier against dust and light. For products that need to be displayed on shelves, shrink film with printed designs can enhance the visual appeal and make the products more eye-catching to potential customers. In summary, our acceptance of all these packaging forms allows us to cater to diverse client requirements and product characteristics, ensuring that every item is packaged in the most appropriate and appealing way possible.
