In logistics, warehousing, and industrial transport, choosing the right packaging materials is crucial. Our 5-layer corrugated boxes (also known as double-wall 5-layer boxes) are designed to meet the needs of industrial-grade transport and storage. Their unique structure provides superior compression resistance, cushioning, and durability, making them ideal for protecting heavy, delicate, or high-value items.
What is a 5-Layer Corrugated Box?
A 5-layer corrugated box is constructed by alternating layers of three layers of linerboard (face paper) and two layers of corrugated core paper, forming a composite structure of "face paper-corrugated-core paper-corrugated-face paper." This double-wall design significantly outperforms ordinary single-layer or three-layer corrugated boxes in terms of strength, puncture resistance, and stacking stability.
Core Structural Advantages:
Two Corrugated Layers: Typically employ a combination of different flute types (e.g., B-flute + C-flute) to balance compression resistance and cushioning performance.
Three Flat Paper Layers: Enhance overall rigidity and provide a smooth printing surface.
Total thickness: Approximately 5-7 mm, load-bearing capacity up to 150 kg or more (depending on size and material).
Typical Applications of Five-Layer Corrugated Cardboard Boxes
1. Industrial Parts and Equipment
Heavy items such as auto parts, machine parts, and motors.
Provides impact and moisture protection, suitable for long-distance transportation.
2. Electronic Products and Precision Instruments
Servers, medical equipment, measuring instruments, etc.
Multi-layer structure effectively absorbs vibration, preventing damage during transportation.
3. Warehousing and Logistics
Bulk goods for long-term storage, suitable for high-level stacking.
Standardized dimensions facilitate shelf management and automated handling.
4. E-commerce and Large Items
Large-volume items such as furniture, home appliances, and fitness equipment.
Customizable brand logo printing enhances the unboxing experience.
Six Reasons to Choose Five-Layer Corrugated Cardboard Boxes
1. Superior Compressive Strength
The double-wall structure allows the box to withstand higher stacking pressure, reducing the risk of deformation during warehousing and transportation.
2. Excellent Cushioning Protection: Double-layer corrugated board forms an air damping layer, effectively absorbing impacts and vibrations to protect the contents.
3. Environmentally Friendly and Sustainable: Made with a high proportion of recycled pulp, 100% recyclable and biodegradable, meeting green supply chain requirements.
4. Flexible Customization: Supports customized sizes, logo printing, added carrying handles, or internal compartments to meet brand and functional needs.
5. Cost-Effective: Lighter than wooden or plastic crates, reducing shipping costs and facilitating mass production.
6. Adaptable to Various Climates: Maintains performance in humid environments by adding a moisture-proof coating or using high-strength wet-strength paper.
How to Choose the Right Five-Layer Corrugated Box?
Step 1: Determine the Characteristics of the Contents
Weight: Is the total weight of the box (including contents) within the load-bearing capacity?
Dimensions: Does the volume of the items match the internal dimensions of the box? It is recommended to allow for cushioning space.
Attributes: Is it fragile, susceptible to pressure, or requires moisture protection?
Step 2: Choose the Flute Combination
BC Flute: The most common combination, balancing strength and cushioning, suitable for most industrial transport.
BE Flute: Thinner and with a smoother surface, suitable for printing intricate designs, used for high-end goods.
AC Flute: Extremely strong load-bearing capacity, suitable for heavy machinery or high-level stacking storage.
Step 3: Confirm Carton Specifications
Paper Weight: Face paper commonly ranges from 175-300 g/m², with higher weight resulting in greater strength.
Carton Structure: Standard slotted carton (RSC), full-top carton (FOL), or accessory carton with lining.
Certification Standards: Such as ISTA (Transportation Testing), BURST STRENGTH, etc.
Step 4: Evaluate the Supplier
Do you provide samples for testing?
Minimum Order Quantity (MOQ) and delivery time?
Do you have relevant industry case studies (e.g., automotive, electronics, chemical)?
Frequently Asked Questions
Q1: What is the cost difference between a five-layer carton and a three-layer carton?
Typically 30-50% more expensive, but the overall cost is often lower by reducing breakage rates, filler, and insurance.
Q2: Can it be used for international sea freight?
Yes, but we recommend a fully waterproof coating or lamination, and ensure compliance with the destination country's phytosanitary requirements (such as ISPM 15 if required).
Q3: What is the standard delivery time?
3-5 days for standard sizes in stock; 7-15 days for custom sizes/printed (depending on quantity).
Q4: How to properly dispose of waste cartons?
Remove the tape, flatten, and hand over to the local recycling system. We recommend reusing at least once before recycling.
Q5: What is the maximum customizable size?
The maximum width of a single piece of cardboard is usually 2.5 meters, with no length limit (segmented production). Special sizes require consultation with production line capabilities.
