White Cardboard: A Benchmark Analysis of Premium Paper Bag Material
2025-10-28
1、 Material characteristics: The perfect combination of thickness, stiffness, and printing adaptability
White cardboard is made of 100% bleached chemical wood pulp, with thick and firm paper. The weight range is usually between 210-400g/㎡, and the surface smoothness, whiteness, and ink absorption are all better than ordinary paper. Its core features include:
（1）High stiffness and durability: White cardboard has a tight fiber structure and strong bending resistance. The paper bags made from it can be placed upright with a load-bearing capacity of 3-5kg, making them suitable for storing heavy goods such as clothing and electronic products.
（2）Excellent color reproduction: The paper surface has high whiteness (A grade whiteness ≥ 92%), even ink absorption, high color saturation and clear layering after printing, and can accurately reproduce brand logos, patterns, and text details.
（3）Moisture resistance and folding resistance: After calendering or embossing treatment, a dense protective layer is formed on the surface of the white cardboard, which can effectively block the penetration of water vapor. At the same time, it has excellent folding resistance and is suitable for making gift bags or food packaging that need to be opened and closed repeatedly.
2、 Technological advantages: from basic models to functional upgrades
The process flexibility of white cardboard bag material is extremely high, and functionalization and personalized customization can be achieved through processes such as lamination, embossing, and hot stamping
（1）Film coating process: Covering the surface of white cardboard with sub film (BOPP or PET) or glossy film to enhance glossiness and wear resistance. After lamination, the surface of the bag is smooth, waterproof and stain resistant, suitable for high-end gift packaging or outdoor use.
（2）Embossing process: By using an embossing machine to press three-dimensional textures (such as cloth and leather) onto paper, the tactile experience is enhanced.
（3）Hot stamping and relief: Combining hot stamping and relief techniques to create a three-dimensional brand logo or pattern.
3、 Environmental Value: Benchmark Selection for Sustainable Packaging
（1）Sustainable raw materials: using FSC certified sustainable forest wood pulp to reduce dependence on primary forests.
（2）High recovery rate: After recycling, it can be re beaten into recycled paper or cardboard with a recovery rate of over 90%.
（3）Degradability: Unplasticized white cardboard bags can naturally degrade within 6-12 months. If a biobased coating (such as PLA) is used for the laminated version, it can also achieve industrial composting degradation and reduce microplastic pollution.
（4）Low carbon footprint: Compared to plastic bags, the carbon emissions of producing 1 ton of white cardboard are about 40% lower, and it can be reused more than 5 times. The total lifecycle carbon emissions are only 1/5 of plastic bags.
Conclusion:
The material of white cardboard bags has become a benchmark choice in the field of high-end bag customization due to its thick and firm texture, excellent printing effect, flexible process customization, and sustainable environmental attributes. Whether it's conveying tone through retail brands, creating emotions in gift scenes, or balancing safety and aesthetics in the food industry, white card paper bags can meet diverse needs through innovative processes.
