For example, food packaging demands boards that meet strict hygiene and safety standards. Consumer goods often require packaging that looks attractive and supports high-quality printing.
Tip: List your product’s weight, size, and storage conditions before choosing a duplex board.
Major packaging companies use several criteria to define the “best” duplex board with grey back. The table below summarizes these key features:
| Criteria/Feature | Description |
|---|---|
| Quality Assurance | Rigorous testing and certifications ensure consistent superiority and compliance with industry standards. |
| Strength and Durability | Boards provide protection during transportation and handling, ensuring package security. |
| Printability | Smooth surface and glossy finishes enable high-quality reproduction of logos, graphics, and text. |
| Versatility | Suitable for various packaging and printing applications across sectors. |
| Cost-effectiveness | Offers maximum performance at reasonable prices, balancing quality and expense. |
| Eco-friendliness | Sustainable production practices appeal to environmentally conscious consumers. |
| GSM Range | Wide options from 180 to 500 GSM to meet different packaging thickness and strength needs. |
| Coating Types | Includes LWC, HWC, and uncoated options to suit printing and packaging requirements. |
| Pulp Quality | Use of virgin or recycled pulp affects board quality and sustainability. |
| Surface Smoothness | Ensures print quality and aesthetic appeal. |
| Thickness Variations | Custom sizes and weights available to meet specific packaging demands. |
Determine Essential Board Properties
Selecting the right duplex board means matching its properties to your packaging goals. High-quality packaging in the consumer goods sector relies on several essential board characteristics:
- Visual appeal: Whiteness, smoothness, and a glossy or silky finish help packaging stand out on shelves.
- Functional strength: Compression strength, folding endurance, and shape stability keep products safe during shipping and handling.
- Manufacturing qualities: Flatness, dust-free surfaces, and good absorption support efficient production and printing.
- Sustainability: Boards made from fresh fibers or recycled materials, with certifications like FSC, show environmental responsibility.
Industry standards help measure these properties. For example, basis weight (GSM) typically ranges from 230 to 500, with a tolerance of ±5%. Brightness on the coated side should reach at least 82%, and smoothness should meet or exceed 55 Sheffield units. These benchmarks ensure the board delivers both protection and visual quality for any packaging application.
Hot Selling Duplex Board with Grey Back/Grey Card Board in Roll and Sheet: Key Quality Indicators
Surface Smoothness and Print Quality
Surface smoothness plays a vital role in the print quality of hot selling duplex board with grey back/grey card board in roll and sheet. Manufacturers design the coated side to be smooth and white, which supports high-resolution printing. The optimal surface smoothness measures at least 120 seconds, allowing for sharp images and vivid colors. Offset printing works well on this surface, making it ideal for packaging that needs to stand out on store shelves.
| Property | Value/Description |
|---|---|
| Surface Smoothness | ≥120 seconds (s) |
| Surface Type | Coated and smooth on one side, grey on the back |
| Printing Method | Suitable for offset printing (high-resolution) |
| Brightness | ≥82% |
| Surface Gloss | ≥45% |
The coated side of hot selling duplex board with grey back/grey card board in roll and sheet provides a clear advantage over recycled or corrugated boards. It delivers better print clarity and a neater appearance. This makes it a preferred choice for packaging chocolates, cosmetics, electronics, and other products that require both durability and attractive graphics.
Tip: Always request a sample print on the actual board to check color vibrancy and image sharpness before placing a large order.
Strength and Durability
Strength and durability ensure that packaging protects products during shipping and storage. Hot selling duplex board with grey back/grey card board in roll and sheet undergoes several tests to measure its performance. These include bursting strength, bending resistance, and moisture resistance. A typical bursting strength value is 310 kPa, while bending resistance reaches 155 mN. The board maintains its shape and strength even in humid conditions, with moisture resistance between 94% and 97%.
| Test Type | Typical Value | Significance |
|---|---|---|
| Bursting Strength | 310 kPa | Resists pressure and rupture |
| Bending Resistance | 155 mN | Maintains flexibility and shape |
| Burst Factor | 28–31 | High resistance to pressure |
| Moisture Resistance | 94–97% | Withstands humid environments |
| GSM Density | 220–250 GSM | Consistent thickness and weight |
Manufacturers also test for compression strength using the Ring Crush Test and Short-Span Compressive Test. These tests confirm that hot selling duplex board with grey back/grey card board in roll and sheet can handle stacking and rough handling. The board’s durability reduces product loss and damage claims during transport.
Consistency and Uniformity
Consistency and uniformity are essential for reliable packaging performance. Manufacturers use advanced technology, such as AI-driven calendering and machine vision systems, to control thickness and reduce defects. These systems help achieve thickness uniformity within ±1%, which is important for die-cutting and automated packaging lines.
Strict quality control procedures check each batch for moisture content, thickness, and strength. Advanced coating machines ensure a uniform finish, giving hot selling duplex board with grey back/grey card board in roll and sheet a consistent look and feel. This uniformity supports efficient production and ensures that every box or package meets the same high standard.
Note: Consistent quality reduces waste and improves the efficiency of packaging operations.
Environmental and Cost Considerations
Sustainability and cost-effectiveness are major factors in choosing packaging materials. Hot selling duplex board with grey back/grey card board in roll and sheet often contains recycled fibers, making it a more environmentally friendly option. The board is recyclable and supports packaging solutions that prioritize environmental responsibility.
Key environmental certifications include FSC and ISO 14001, which show responsible sourcing and sustainable production. These certifications help companies meet global standards for eco-friendly packaging.
From a cost perspective, hot selling duplex board with grey back/grey card board in roll and sheet offers a balance between price and performance. Recycling in the production process can reduce costs by 20–30%. The board is positioned in the mid-range price bracket, making it more affordable than premium packaging boards but still offering excellent print quality and durability.
| Material Type | Price Range (USD per ton) | Notes |
|---|---|---|
| Grey Board | $380 – $480 | Price varies by quantity and supplier |
| Duplex Board with Grey Back | Mid-range | Similar to grey board |
