290g 白面涂布灰底白板纸卷供应

Answer: The core difference is the base material and cost. White top coated paperuses recycled pulp (grey back) with single-sided white coating, featuring high cost-performance and basic stiffness. Art paper uses full wood pulp with double-sided coating, offering better printing texture but higher price. Choose based on budget and packaging/printing requirements.

Answer: Yes. Its smooth white coating ensures good ink adhesion and color reproduction, making it fully compatible with offset printing (for high-precision posters, gift boxes) and flexographic printing (for packaging bags, cartons). For best results, select the appropriate basis weight (140-200g/㎡ recommended for printing).

Answer: Match basis weight to usage scenarios:
- 120-140g/㎡: Lightweight packaging (snack liners, thin cartons).
- 160-180g/㎡: General packaging (express boxes, food boxes, shopping bags).
- 200-300g/㎡: High-end/high-load packaging (cosmetics boxes, electronic product boxes, large gift boxes).

Answer: Yes. It uses recycled pulp as the base material, reducing resource waste. The coating meets environmental standards (no harmful residues). Waste paper can be recycled as general paper waste, conforming to green packaging concepts.

Answer: Common reasons: ① Insufficient ink adaptation (use ink suitable for coated paper). ② Uneven paper thickness (choose products with strict thickness control). ③ Improper printing pressure (adjust printer parameters according to basis weight).

Answer: Yes. Regular sheet sizes (787×1092mm, 889×1194mm) are available. Custom sheet sizes, special shapes, or roll forms are also supported to meet specific packaging/printing needs (e.g., roll paper for continuous printing of labels).

Answer: Store in a cool, dry, well-ventilated environment (temperature 15-30℃, humidity 40%-60%). Avoid direct sunlight and high humidity (to prevent deformation or moisture absorption). Stack neatly and avoid heavy pressure on the paper edges.
