TONLI's Double-Sided Black Pearl Series is developed for this purpose. It is produced from natural wood pulp material and finished with imported pearlescent materials, providing an even double-sided pearlescent look as well as high stiffness and resistance to scratches, peeling, water, tearing and sunlight. Available in various grammages and finishes.
Coated on two sides = C2S. Both sides are coated, which makes the paper smoother and more beautiful than uncoated paper.
Depending on the use, the amount of weight required varies. Lighter grades are suitable for cards and tags, and heavier grades for packaging and covers.
The coating brings another element: Pearlescent C2S paper is coated to make it look pretty. The pearlescent effect from the surface allows light to reflect, adding a gentle shimmer to dark packaging and dark print designs, which makes them stand out more.
The Black Pearl Series features three main attributes: a double-sided look, a long-lasting coating, and versatility of processing.
Imported synthetic mica titanium pearlescent powder and a symmetrical coating process are used on the paper. The resulting effect is the same pearlescent look on both sides. Deep black base is achieved by full pulp dyeing, which helps ensure a uniform black tone and helps minimize whitening at the folded edges.
The surface is so pearlescent because an acrylic polyurethane baking coating with a stated 5B adhesion level is used. It is meant to be resistant to peeling, abrasion, and scratches.
The paper is also indicated to be waterproof, tear-resistant, and sun-resistant, ensuring extra protection for the final products.
Premium packaging can use a number of finishing methods. This C2S paper is designed to help with processes such as:
● The hot stamping of gold and silver.
● UV printing and coating
● Deep embossing.
● Debossing
● Lamination
● Die-cutting
The selection of the proper gramage is of importance because the number of grams per square meter of paper has an impact on product thickness, stiffness, and type of finished product it can support.

Heavy grades are ideal for boxes for gifts, jewellery, cosmetics, cigar boxes, tea boxes and other high quality product packaging.
The lighter grades can be used for hang tags, price tags, greeting cards, invitations, envelopes and creative product inserts. These applications can be applied to a specialty surface, but do not need a heavy board.
For notebook/brochure covers, as well as hardcover book covers, a higher grammage can be used. The appearance is decorative, as well as stiff for covers.
Medium weight grades can be used for shopping bags and presentation bags where good looks and structural strength are both essential.
Higher grades offer a sturdier construction for collector's editions, commemorative boxes and deluxe gift packaging.
For certain specialty papers, special print equipment or a converting process or design may be required. The Black Pearl Series can be customized in a number of ways.
Grammage and Format: They can be supplied in various weights and cut into sheets or rolls.
Pearlescent effect: Finishes can be provided in a high-gloss mirror finish, a soft matte pearlescent, or an iridescent finish.
Processing: Coating may be optimized for various processes like hot stamping, UV coating, embossing, and die-cutting.
Color consistency: Only special formulas can be created that will ensure that the blackness and pearlescent effect remain uniform throughout the production runs.
If it is a bigger project, then it may proceed from the sample stage to the confirmation stage and then the small batch trial production stage to the mass production stage.
For large orders, it is important that the product be consistent from one batch to the next.
The specifications provided give a value of ΔE ≤ 0.5, moisture content of 6–8%, and batch fluctuation of no more than 3%. The blackness, gloss, and pearlescent effect are controlled by pearlescent powder and coating materials.
This becomes crucial for brands making the packaging several times, as they might see noticeable differences between the batches, which can impact the overall presentation.
Another consideration in choosing packaging paper is the environment.
The Black Pearl Series is made with 100% natural wood pulp and a water-based baking coating system. The product information indicates that it is 100% FSC certified, free of heavy metals and fluorescent agents, and can be recycled. The product information also mentions REACH compliance.
Buyers of export projects should ensure they make their own checks as to the particular certificates and documentation needed in their respective export market.
The best paper will vary with the actual product and the production requirements.
Before ordering, consider:
● Application: Determine if it is going to be used for tags, cards, bags, covers or boxes.
● Grammage: Select the weight that will give the desired thickness and stiffness.
● Finishing: Ensure that the appropriate stamping, embossing, UV or cutting process can be used.
● Surface effect: Choose the desired pearlescent effect in line with the product design.
● Repeat or large orders: Batch consistency and quality controls are checked for production volume.
● Compliance: Ensure compliance with your market's certifications.
