2. Product Overview
Our Jinqiao Grey Cardboard is a top - notch packaging solution for boxes, designed to meet various industrial and commercial needs. It is made from a carefully selected blend of virgin and recycled pulp, which not only ensures its durability but also reflects our commitment to environmental protection.
2.1 Technical Specifications
Grammage: Ranging from 230 - 450 gsm, providing different levels of thickness and strength to suit various applications. The wide range of grammages allows customers to choose the most appropriate product according to the weight and nature of the items to be packaged.
Thickness: Varies from 0.3 - 1.5 mm. Precise thickness control ensures that the cardboard can maintain its structural integrity while being flexible enough for different box - making processes.
Tensile Strength: With a tensile strength of 8 - 12 kN/m, the Jinqiao Grey Cardboard can withstand a certain degree of pulling force during handling and transportation, effectively protecting the packaged products.
Brightness: It has a brightness of 85 - 90% (ISO 2470), which is beneficial for printing. The relatively high brightness provides a good background for printing various patterns and texts, making the packaging more eye - catching.
2.2 Surface Coating
Clay - Coated (C1S): The clay - coated surface of the cardboard offers a smooth texture. This smoothness is crucial for achieving high - quality printing results. When printing, the ink can be evenly absorbed on the surface, ensuring that the printed patterns, logos, and product information are clear and vivid. It can achieve 95% ink absorption uniformity, enabling vibrant, high - definition prints.
Optional PE - Laminated: For applications that require enhanced moisture resistance, we offer the option of PE - laminated cardboard. The water - based PE coating can effectively resist humidity, which is especially important for products that are sensitive to moisture, such as food, electronics, and some handicrafts.
3. Product Advantages
3.1 Unmatched Durability
High Stiffness: Engineered to withstand handling and transportation, the Jinqiao Grey Cardboard has excellent bending resistance, exceeding 120 mN. This high stiffness ensures that the boxes made from our cardboard can maintain their shape during storage, transportation, and handling, thus protecting the items inside. Whether it is being stacked in a warehouse or transported over long distances, the cardboard boxes can provide reliable protection.
Moisture Resistance: Thanks to the optional water - based PE coatings, the cardboard has good moisture resistance. This feature is critical for preserving the quality of the packaged products, especially in humid environments. For example, when used for food packaging, it can prevent the ingress of moisture, which may cause spoilage or affect the taste and texture of the food.
3.2 Printability and Aesthetics
Smooth Surface: As mentioned above, the coated top layer provides a smooth surface for printing. This not only allows for clear and detailed printing but also enables various post - printing processes. For instance, it can support foil stamping (such as gold/silver), which can add a touch of luxury to the packaging. Embossing can also be easily applied to create a three - dimensional effect, enhancing the tactile experience of the packaging.
Custom Finishes: The cardboard is highly compatible with different custom finishes. Velvet lamination can be used to give the packaging a soft and elegant feel, which is very suitable for high - end products such as jewelry and cosmetics. These custom finishes can effectively align with the brand image and marketing strategies of different products, making the packaging more attractive and competitive in the market.
3.3 Sustainability
Recycled Content: Manufactured with 30 - 50% post - consumer recycled pulp, our Jinqiao Grey Cardboard is an environmentally friendly choice. By using recycled materials, we reduce the demand for virgin pulp, which helps to conserve forests and natural resources. The use of recycled pulp also contributes to reducing waste in landfills.
Eco - friendly Coatings: We use water - based adhesives and coatings in the production process, which significantly reduces VOC (Volatile Organic Compound) emissions. These eco - friendly coatings not only meet EU REACH and US FDA standards for food - contact materials but also demonstrate our company's commitment to environmental protection and sustainable development.
4. Applications
4.1 Jewelry Packaging
Rigid Box Construction: The Jinqiao Grey Cardboard is ideal for making hinged or slide - out jewelry boxes. With a thickness tolerance of ≤ 1.5 mm, it can provide a luxurious feel while ensuring the safety of the jewelry. The high stiffness of the cardboard can prevent the box from being easily deformed, protecting delicate jewelry such as rings, necklaces, and watches during transportation and display.
Insert Integration: It supports die - cut foam or velvet inserts. These inserts can be precisely designed to fit the shape of different jewelry items, providing a secure and elegant placement for the products. The combination of the sturdy cardboard box and the soft inserts can enhance the overall aesthetic and protective function of the jewelry packaging.
4.2 Food Packaging
Structural Integrity: For food packaging, the durability and moisture resistance of the Jinqiao Grey Cardboard are of great significance. It can be used to make food boxes, trays, and cartons that can withstand the weight of food products and protect them from external factors such as moisture and dust. The smooth surface also allows for clear printing of food - related information, such as ingredients, expiration dates, and cooking instructions.
Compliance with Standards: Since our cardboard meets EU REACH and US FDA standards for food - contact materials, it is a reliable choice for food packaging. This compliance ensures the safety of food products and gives consumers confidence in the quality of the packaging.
4.3 General Product Packaging
Versatility: In addition to jewelry and food packaging, the Jinqiao Grey Cardboard can be widely used in the packaging of various other products, such as electronics, handicrafts, and consumer goods. Its excellent printability and customizable finishes make it suitable for creating unique packaging that can attract consumers' attention and effectively promote products. Whether it is a small electronic device or a delicate handicraft, the cardboard can be tailored to meet the specific packaging requirements.
5. Environmental Compliance
Certifications: Our Jinqiao Grey Cardboard has obtained important certifications such as FSC® mix (FSC - C 024388) and SGS (heavy metal free). The FSC certification ensures that the wood raw materials used in the production process come from sustainably managed forests, while the SGS certification guarantees that the product is free of heavy metals, which is in line with international environmental and safety standards.
Closed - loop Manufacturing: We implement closed - loop manufacturing processes in our factory. Water recycling systems are installed to reduce freshwater usage by 30%.

8. Future - proofing Sustainability
We are constantly investing in research and development to improve the sustainability of our products. Currently, we are working on biodegradable variants, such as PLA - coated boards. These biodegradable materials can decompose naturally in the environment, reducing the environmental burden caused by traditional packaging materials. In addition, we are developing lightweight formulations (180 - 200 gsm) to further reduce material consumption while maintaining product performance. By 2026, we aim to achieve 100% renewable energy usage in our Dongguan facility, with the support of provincial subsidies under the 14th Five - Year Plan. This goal reflects our long - term commitment to environmental protection and sustainable development.
