Product Definition:
White cardboard refers to a single or multi-layer combination of paper that is entirely produced from bleached chemical pulp and fully sized. It typically has a grammage exceeding 150g/㎡.
1.Product Characteristics:
Appearance Quality:
- High Whiteness: White cardboard exhibits exceptional whiteness, providing a clean and bright surface that serves as an ideal background for printing. This enhances the clarity and brightness of printed patterns and text, improving overall visual appeal.
- High Smoothness: The paper's surface undergoes fine treatment, resulting in excellent smoothness and a refined tactile experience. This effectively minimizes dot deformation and ink diffusion during printing, ensuring print clarity and layering.
- Good Evenness: The fiber distribution is uniform, with consistent paper thickness that avoids localized thickness variations or spots. This stability enhances the reliability of the printing and packaging processes while contributing to the product's overall quality.
2.Physical Properties:
- Good Stiffness: The texture is robust and thick, offering high stiffness and hardness. This resistance to bending and deformation allows it to withstand significant pressure and weight, making it suitable for various packaging and printed materials requiring shape retention, such as packaging boxes and hardcover book covers.
- High Strength: White cardboard demonstrates excellent tensile and tear strength, reducing the likelihood of breakage during processing, transportation, and use. This ensures the protection of contents within the packaging.
- Good Dimensional Stability: With minimal expansion and contraction, white cardboard remains largely unaffected by environmental humidity and temperature changes, maintaining stable dimensions to ensure precise printing and packaging.
3.Product Use:
Packaging Field:
White cardboard is extensively utilized in the production of high-end packaging boxes for tobacco, pharmaceuticals, cosmetics, food, liquids, and other industries. Its superior stiffness and printing performance elevate the packaging grade of products, attracting consumer attention. For instance, cosmetic packaging using white cardboard can effectively showcase brand image and product features through intricate printing. Additionally, white cardboard for food packaging ensures safety and hygiene while enhancing product appeal through vibrant printed designs.
4.Printing Field:
Suitable for producing business cards, invitations, certificates, trademarks, postcards, greeting cards, monthly calendars, and other printed materials. The high whiteness and excellent ink absorption properties of white cardboard result in vivid and realistic print colors, delivering a premium and sophisticated appearance. For example, white cardstock business cards reflect a professional image for individuals or enterprises, while invitation cards made from white cardstock add gravitas to formal events.
5.Production Technology:
White cardboard is generally manufactured using a bleached chemical pulping process, with high-quality wood pulp as the primary raw material. The production involves beating, sizing, filling, copying, drying, pressing, and other processes. Strict control of process parameters at each stage ensures consistent paper quality. For instance, precise control of fiber cutting and spinning during the beating process enhances paper strength and printing performance. Sizing improves water resistance and ink absorption, further optimizing the material's functionality.
6.Product Advantages:
- High Cost-Effectiveness: Despite its relatively higher price, white cardboard's superior performance reduces losses during printing and packaging, improves production efficiency, and increases product value. From an overall perspective, it offers excellent cost-effectiveness.
- Good Environmental Performance: Utilizing natural wood pulp as a renewable resource, the production process emphasizes environmental protection by minimizing pollutant emissions, aligning with modern society's demand for eco-friendly products.
- Wide Range of Applications: Due to its outstanding characteristics, white cardboard is applicable across nearly all sectors requiring high-quality paper, whether for high-end product packaging or the production of fine prints.
