How many layers does a typical packaging box have?
Published Time:
2025-07-14
The number of layers in a packaging box is not fixed, mainly depending on its functional requirements (such as protection, load-bearing, display, etc.), the characteristics of the packaged product (weight, fragility, value, etc.), and the cost budget. Common layer classifications and application scenarios are as follows: I. Classification by structural layers (taking paper packaging boxes as an example, the most common) Single-layer structure Made directly from a single material board, such as single-layer cardboard, thin corrugated board (such as E flute, F flute). Features: Lightweight, low cost, suitable for packaging lightweight and non-easily damaged products, such as small cosmetic samples, small snacks, cards, etc. Double-layer/Multi-layer composite structure Made by superimposing and bonding two or more materials, such as "cardboard + corrugated board", "kraft paper + plastic film", etc. Features: Combines certain rigidity and cushioning, often used for medium-sized products, such as toys, stationery, and inner boxes of ordinary electronic products. Three-layer corrugated structure Composed of two layers of face paper (outer layer and inner layer) and one layer of corrugated core paper (corrugated shapes include U-shaped, V-shaped, etc.), which is the most commonly used corrugated packaging box structure. Features: High cost performance, moderate cushioning and load-bearing capacity, widely used in food, daily necessities, clothing, etc., for transportation packaging or sales packaging. Five-layer corrugated structure Composed of two layers of face paper, two layers of core paper, and one layer of corrugated core paper (structure: face paper + corrugation + core paper + corrugation + face paper). Features: Strong load-bearing and impact resistance, suitable for packaging heavy or fragile products, such as transportation packaging of home appliances, furniture, and large mechanical parts. Seven-layer and above corrugated structure Multiple layers of corrugation are superimposed, rarely used for ordinary packaging, mainly used in scenarios with ultra-heavy weight and high protection requirements, such as long-distance transportation packaging of large industrial equipment and precision instruments.

I. Classification by structural layers (taking paper packaging boxes as an example, the most common one)
Single-layer structure
Made directly from a single material board, such as single-layer cardboard, thin corrugated board (such as E flute, F flute).
Features: Lightweight, low cost, suitable for packaging lightweight and non-easily damaged products, such as small cosmetic samples, small snacks, cards, etc.
Double-layer / Multi-layer composite structure
Made by superimposing and bonding two or more materials, such as "cardboard + corrugated board" and "kraft paper + plastic film".
Features: It combines a certain degree of rigidity and cushioning, and is often used for medium-sized products, such as toys, stationery, and inner boxes of ordinary electronic products.
Three-layer corrugated structure
It consists of two layers of face paper (outer layer and inner layer) and a layer of corrugated core paper (the corrugated shape is U-shaped, V-shaped, etc.), which is the most commonly used corrugated packaging box structure.
Features: High cost performance, moderate cushioning and load-bearing capacity, widely used in food, daily necessities, clothing, etc., for transportation packaging or sales packaging.
Five-layer corrugated structure
It consists of two layers of face paper, two layers of core paper, and one layer of corrugated core paper (structure: face paper + corrugation + core paper + corrugation + face paper).
Features: Strong load-bearing and impact resistance, suitable for packaging heavy or fragile products, such as the transportation packaging of home appliances, furniture, and large mechanical parts.
Seven-layer and above corrugated structure
Multiple layers of corrugation are superimposed, rarely used in ordinary packaging, mainly used in scenarios with ultra-heavy weight and high protection requirements, such as long-distance transportation packaging of large industrial equipment and precision instruments.
