مصنع متخصص في تصنيع علب المجوهرات من جلد البولي يوريثان بلون المطر

يودينج artificial leather factory with 37 years of experience specializing in PU synthetic leather, leverages its extensive craftsmanship and mature R&D capabilities to develop a rain-textured PU leather specifically for the jewelry box industry. This material meets the stringent standards of the high-end packaging industry in terms of visual appeal, performance, environmental friendliness, and processability, making it an ideal outer covering material for mid- to high-end jewelry box manufacturers.

The so-called “rain-textured” pattern refers to the fine, vertical, linear lines created on the PU surface through precise roller embossing technology. This texture offers several advantages:

Strong Visual Extension: The rain-textured pattern creates a natural sense of depth, visually stretching the appearance of jewelry boxes and making them appear more slender and refined. It is particularly suitable for rectangular, clamshell, and drawer-style packaging.

Soft Gloss: The texture creates a natural matte finish under refracted light, avoiding the perceived cheapness of high reflectivity and more in line with the high-end market’s aesthetic requirements for a “subtle and refined” look.

Excellent Scratch Resistance: The texture’s concave and convex structure effectively reduces surface scratches caused by daily friction, extending the product’s lifespan.

High Processing Stability: Rain-textured PU performs exceptionally well in hot press forming, lamination, hemming, and crimping processes, preventing blistering, cracking, or springback. It is suitable for both automated and manual laminating processes.

This texture is created using high-precision embossing rollers with a mold accuracy of ±0.01mm, ensuring batch consistency and making it suitable for large-scale production and brand standardization.

Customized service to create brand-exclusive texture

Yudeng understands that packaging designers and brand owners often have highly specific material customization requirements. Therefore, we offer the following comprehensive customization services:

Color System:

• Supports PANTONE and RAL color matching.
• We offer special color finishes such as pearlescent, matte, semi-gloss, metallic, laser, and two-tone gradients.
• All color combinations are double-checked by a computerized color matching system and manual color correction, with a color difference delta E ≤ 0.8.

Thickness and Hand Feel Adjustment:

• Common thicknesses are 0.6mm, 0.8mm, 1.0mm, and 1.2mm.
• We can adjust the foam layer thickness or increase the base fabric weight based on customer requirements for stiffness and fit.
• We offer three hand feel options: soft, medium, and firm, to meet the design requirements of various structures (such as magnetic lids and drawers).

Backing Variety:

Non-woven fabric (cost-effective), knitted fabric (high tensile strength), rayon fabric (for enhanced texture), and microfiber fleece (luxury grade). Supports lamination with flame-retardant or fiber-reinforced backings, making it suitable for gift boxes subject to stringent air travel and transportation requirements.

Surface Finishing:

• The raindrop pattern can be laminated with heat transfer patterns, hot stamping, laser engraving, and other features.
• Waterproof, anti-fingerprint, and oil-repellent coatings are customizable to enhance outdoor and transportation performance.

REACH/ROHS environmental certification

Environmental protection is a key focus of Yudeng’s product development, especially within the international brand packaging supply chain, where compliance with environmental regulations is crucial. Our Rain Silk PU leather boasts a comprehensive green certification system:

TÜV Süd Certification: A leading German testing agency. Products certified by TÜV can be used in high-standard consumer product packaging in the EU and North American markets.

REACH Compliance: Tested for 197 Substances of Very High Concern (SVHC), meeting EU chemical regulations.

ROHS 2.0: Controls the content of 10 hazardous substances, ensuring cadmium-free, lead-free, and mercury-free, making it suitable for electronic packaging extensions.

VOC Emission Control: SGS testing confirms that volatile organic compound emissions are 40% below industry standards, ensuring safety for both production and end users.

Production Application

Rain Silk PU leather is more than just a material; it is part of the jewelry box brand story, conveying both aesthetics and trust. The following are common application scenarios and advantages:

High-end jewelry boxes: Whether for gold or silver jewelry, jewellery, or pendant boxes, the subtle rain-pattern texture combined with the embossed logo lends the box a premium character, helping brands establish a strong first impression.

Watch/glasses collection boxes: The texture enhances the visual sophistication, and the structure resists springback after fitting, making it suitable for multi-layer drawer designs.

Cosmetics and perfume packaging: Velvet lining and metal frames can be paired for an elegant finish.

Art collection boxes/custom gift boxes: Adhering to environmental principles, these boxes offer eco-friendly, high-quality solutions for cultural and creative products or gift-giving.

Customized corporate gift boxes: Supporting large-scale custom colour and texture combinations, enabling rapid implementation of brand-specific packaging.
