Costs of Corrugated Paper Boxes

Several factors influence the cost of our corrugated paper boxes:

Material Quality

Higher quality materials, such as premium white or kraft paper, and some special texure color paper, increase costs but provide better durability and strength.

Customization

Custom designs, sizes, and prints can add to the cost. Detailed graphics, special coatings, and unique structures typically result in higher prices.

Order Volume

Ordering in bulk reduces the cost per unit due to economies of scale. Larger orders spread fixed costs over more units, lowering the price for each box.

Shipping

The destination and shipping method impact overall costs. Shipping costs vary based on distance, weight, and shipping speed.

Corrugated Color Boxes

About 0.25~1.00 USD/pcs for reference.

Flatbed paper packaging

About 0.20~1.00 USD/pcs for reference.

Cartons

Here’s a simple way to calculate the cost of your cartons:

Formula: (L + W + 5) * (W + H + 3) * 2 * 0.155/1000 * Material Cost = Box Price

Example: Given values:

Length (L): 50 cm
Width (W): 40 cm
Height (H): 30 cm
Material Cost: $2.90

Calculation: (50 + 40 + 5) * (40 + 30 + 3) * 2 * 0.155/1000 * 2.90 = $0.90 per box

Calculation: $0.90 per box

To calculate for different sizes, just replace L, W, and H with your own measurements. Note, this is a rough estimate.

Response Time

Minimum 2 weeks for fully designed packaging.
Usually 1 week for samples arranged directly or with minor modifications based on the customer’s profile.

Step 2: Raw Material Preparation

The first step in mass production for corrugated color boxes is preparing the raw materials. This involves cutting the face paper to size, producing corrugated board as per the sample, and entering this information into the company’s system. Additionally, materials are inspected, and the edges of the face paper are trimmed to prevent debris on the printing surface.

Response Time

Normally 3-5 days.

Step 3: Printing

Printing on paper using offset, flexographic, or other methods according to a confirmed sample or artwork.

Response Time

Normally 2-4 days.

Step 4: Surface Treatment

The surface treatment process typically takes 2 to 3 days. If special coatings are applied, such as spot UV, hot foil-stamping, embossing, or debossing, the total process time extends to 4 to 6 days. Please consider this when planning your production schedule.

Response Time

Normal Coating Method: 2-3 days.
With Special Varnish (spot UV, hot foil-stamping, embossing, debossing): 4-6 days total.

Step 5: Corrugated Board Laminating

The lamination process for corrugated board typically takes 2 to 3 days, including a natural drying time of 12-24 hours. If the box requires two sheets of printing paper laminated with the corrugated board, an additional 3 to 4 days is needed for natural drying before proceeding to the next step. Please consider this when planning your timeline.

Response Time

Normal Lamination: 2-3 days.
With Two Sheets of Printing Paper: 5-7 days total to ensure proper drying time.

Step 6: Die-cutting

The die-cutting process for paper boxes typically takes around 2 to 3 days. This timeframe is accurate once the sample has been confirmed. This is a crucial step in production, ensuring the dimensions and shape of the final product.

Response Time

Normally 2-3 days.

Step 7: Folding and Gluing

Assemble the boxes by folding along the creases and gluing the necessary parts.

Response Time

Normally 2-3 days.

Testing-Ensuring Quality and Durability

Our comprehensive testing ensures the highest quality and durability for our color corrugated paper boxes. Each box undergoes rigorous testing to meet industry standards and customer requirements. Testing Timeline: Normally 2-3 days.

Edge Crush Test (ECT)

Measures the box's ability to withstand edgewise compression.

The ECT is performed by compressing a sample of corrugated material until it collapses. This test evaluates the stacking strength and durability of the boxes, with results expressed in pounds per inch (lb/in) or kilonewtons per meter (kN/m). Proper ECT-rated corrugated board provides equivalent strength using less material, promoting sustainability.

Bursting Strength Test

Determines the box's resistance to bursting under pressure.

This test involves applying pressure to the corrugated board until it bursts, measured in pounds per square inch (psi). It ensures the box can handle internal and external pressure without failing, providing essential data for packaging heavy or awkwardly shaped items.

Drop Test

Assesses the box's ability to protect contents from impacts.

The drop test simulates real-world handling by dropping the box from a specified height to evaluate its structural integrity and protective capability during transit.

The international standard for drop test is shown below:

Ink Decolorization Test

Ensures printing content and patterns are resistant to scratching.

This test involves rubbing the printed area with a specified force to check for any ink decolorization, ensuring durable and legible branding.

Humidity Testing

Verifies the packaging's moisture content before shipping.

The finished product is tested for moisture to ensure proper drying, preventing softness and maintaining the box’s hardness during transit.

Pantone Colorimeter Test

Ensures color consistency across different batches.

A colorimeter measures the LAB values of the printed boxes to minimize color differences and maintain brand consistency.

Constant Temperature and Humidity Chamber

Tests the box's performance under extreme conditions.

Boxes are placed in a controlled environment to simulate extreme conditions, ensuring they don’t deform, delaminate, or lose adhesion.

Adhesive Tension Test

Verifies the strength of adhesive bonds.

This test measures the tension strength of adhesive bonds to ensure they can withstand required forces without failing.

Gloss Test

Ensures the glossiness of materials and some coatings meets specifications.

The surface gloss level is measured to ensure it meets the specified standards for appearance and quality.

Paper Thickness Testing

Confirms the correct basis weight of the paper used.

The thickness of the paper is measured to verify it meets the specified requirements for strength and durability.
