Products Description
Our dark kraft paper is made of high-density virgin wood pulp with an eco-friendly penetrating dyeing process. It features a flat, clean and defect-free surface with uniform batch color and stable color fastness. Effectively avoiding the common defects of ordinary dyed paper such as brittleness, fading and color difference, the paper has excellent toughness and burst resistance. Compatible with white ink printing, hot stamping, embossing and other processing technologies, it is non-toxic, odorless and environmentally compliant, ideal for high-end gift boxes, brand paper bags, cultural and creative tags and premium packaging.

Production Line
We adopt fully automatic integrated production lines for standardized production of dark kraft paper, covering automatic pulp screening, precise color matching, high-temperature color fixation, high-pressure shaping, constant-temperature drying and precision slitting and rewinding. Equipped with professional color calibration and physical performance testing equipment, the production line strictly controls paper gram weight, thickness, chroma and toughness, eliminating batch color difference, uneven thickness and surface defects. It supports stable mass production and continuous supply for foreign trade orders.
Packaging&Shipping
All finished products adopt export-standard moisture-proof and waterproof packaging. Papers are stacked neatly and sealed with film for moisture resistance, and reinforced with thickened kraft paper and cardboard edges to prevent moisture, warping, deformation and damage during transportation. Sheets are palletized and rolls are well protected. All goods are packaged in order with clear specifications and batch marks. We support FCL, LCL and small-batch shipments with stable logistics, ensuring fast and intact delivery for cross-border orders.

FAQ
Q1: Is the dark kraft paper prone to fading or whitening? A: No. Adopting high-temperature penetration color fixing technology, the paper owns high color fastness and stable tone, without fading, whitening or graying under normal use and storage conditions.
Q2: Will dyed dark paper become brittle with poor tensile strength? A: No. With high-density virgin fiber and optimized dyeing formula, it avoids the common brittleness and poor tension problems of ordinary dyed dark paper, maintaining stable toughness and tear resistance.
Q3: Does it support white ink printing, hot stamping and embossing? A: Fully supported. The matte, smooth and flat paper surface ensures even ink absorption and strong adhesion. It presents high-grade and three-dimensional effects for white ink printing, color printing, gold/silver stamping and embossing.
Q4: Does the product meet cross-border export environmental standards? A: Yes. Adopting odor-free and eco-friendly dye materials with zero harmful residues, it complies with international environmental standards and is fully suitable for global export orders.
