Layered and stapling methods
The difference between single-tile, double-tile, and three-tile tiles can be classified according to their layered, capped, and nailing methods.
Common cardboard boxes are divided into three-layer and five-layer. Products that are not easily damaged by pressure generally choose three-layer boxes (but the quality of the three-layer cardboard box must be good, and it must be sealed and waterproof). Products that are sensitive to pressure and shock, as well as valuable electronic products, generally use five-layer cardboard boxes.
Common cardboard box types include: full-top, half-top, and top-and-bottom box. Factory packaging boxes generally use full-top boxes; merchant goods almost always use half-top boxes; while top-and-bottom box boxes are mostly used for gift packaging boxes, jewelry boxes, shoe boxes, etc.
The most common methods are gluing and stapling. Stapling usually involves three staples. When the paper is not easily damaged, stapling is a very reliable bonding method.

Composition of Corrugated Cardboard
Corrugated cardboard typically consists of face paper, corrugated paper, liner paper, and core paper.
Face paper: The outermost layer of paper laminated to the corrugations; face paper is usually thicker, commonly with a grammage >250g.
Corrugated paper: Also called fluted paper, this is the middle layer of paper with undulating corrugations; commonly A-flute, B-flute, C-flute, or E-flute.
Liner/Bottom paper: The bottom layer, corresponding to the face paper, commonly with a grammage of 100~140a.
Common colors for face paper and liner paper: white, natural color.

F-flute: Extremely thin flute, used for packaging hamburgers, snacks, digital cameras, refrigerated goods, etc.
Corrugated Wave Shapes
U-shaped corrugation: Good elasticity and adhesion, but due to the large amount of paper and adhesive used, it has low flat-press elasticity and can only recover its shape within its elastic limit. Excessive pressure will prevent it from returning to its original shape.
V-shaped corrugation: Approximately triangular in shape, it stands upright well, but has poor recovery and adhesion.
UV-type corrugation: Compared to the previous two, it has higher compressive strength. UV-type corrugation is currently more popular in the market and offers better performance.

Q1: What is the technical difference between Single-Wall, Double-Wall, and Triple-Wall Corrugated Boxes?
A: The configuration of the box determines its ultimate compression strength, its puncture resistance and its payload.
Single-Wall Corrugated Boxes (3-Ply / 三层坑箱): A single wavy fluted medium thickness layer is sandwiched between two flat thickness linerboards. Single-Wall Corrugated Boxes are our standard shipping mailers used for e-commerce, fast-moving consumer goods (FMCG) and inner product packaging in retail environments. They can hold loads of up to 10kg - 15kg and are cost effective for larger volume usage.
Double-Wall Corrugated Boxes (5-Ply / 五层坑箱): The boxes are made up of two layers of fluted mediums in the middle that are split by a center linerboard and both layers are then wrapped by two outer liners such as AB-flute or BC-flute. The recommended use for these types of packaging materials are for heavy electronics, automotive parts, long distance global shipping, and for stacking in maritime containers with payloads of up to 30kg - 40kg.
Triple-Wall Corrugated Boxes (7-Ply / 七层坑箱): triple fluted mediums triple layered, four liners, industrial grade triple wall corrugated box that can substitute for heavy wood crates for very large bulk items such as bulk chemical drums, heavy machinery parts and machinery in general that are very large and heavy weighing up to 100kg+ and above. -
Q2: How do we choose the right flute profile (A, B, C, E, or Combined Flutes) for our packaging contract?
A: There are different profiles. The goal of a profile is to optimize the stacking strength of layers, and the surface smoothness that is required for printing on the layers.
A-Flute (4.8mm) / C-Flute (4.0mm): For vertical top-to-bottom compression and cushioning – ideal for warehouse stack patterns.
B-Flute (approx. 3.2mm) & E-Flute (approx. 1.6mm): These corrugations feature very short and close spaced flutes. They have excellent flat crush resistance and produce a smooth surface liner with minimal “washboarding”. These corrugations are very suitable for crisp printing with flexographic ink or high-definition litho-laminated graphic printing.
Combined Flutes (e.g. BC or AB Flutes): The densest flute, paired with a tall flute to provide the highest structural stacking strength, while providing excellent external puncture resistance to withstand tough shipping environments. -
Q3: What is the difference between Edge Crush Test (ECT) and Mullen Burst Test ratings on corrugated packaging?
A: These two metrics allow to assess different structural safety aspects of a global supply chain.
Edge Crush Test (ECT): The test measures the cross-sectional compression strength of the corrugated board along the vertical edge of the board. This test result is key when boxes are going to be stacked on top of each other in a warehouse pallet arrangement. Therefore we recommend to check for high test results such as 32 ECT, 44 ECT or even 50 ECT.
Mullen Burst Test (Bursting Strength): This test measures the hydrostatic pressure required to rupture or puncture the flat face of corrugated board. It indicates how well the box resists damage from rough handling and from inside shifting of contents as well as puncture damage from outside sources during the shipping process. The standard premium grades of corrugated board have a bursting strength of between 200 lbs/sq.inch and 350 lbs/sq.inch. -
Q4: How does your factory protect corrugated boxes from collapsing or softening during long-distance maritime shipping?
A: Excessive humidity in a container can destroy the fibers in normal grade of paper used in corrugated to cause it to become structurally soft. We prevent this from happening by using High-Sizing Waterproof Liners in our corrugated boxes and by adding moisture-resistant resin compounds into our starch adhesive lines. For shipments that are to be transported as cold-chain products or for agricultural products, we can also apply an Advanced Hydrophobic Poly-Coating or a Wax-Free Eco-Shield Barrier to the inner surface and the outer surface of our liners. This prevents normal ambient sea moisture from penetrating into the flutes of the corrugated box and from causing the corrugated box to become structurally soft thereby allowing the boxes to be stacked to their full ECT ratings while in transit around the world. -
Q5: What is Litho-Lamination (Offset Corrugated), and when should we choose it over standard Flexographic printing?
A: The choice depends on the visual positioning of your retail or e-commerce brand:
Direct Flexographic Printing (High-Speed Eco-Print): The print is directly applied to the corrugated board by the automated inline folder-gluers. This is cost effective and fast print process that can be used for shipping cartons, logistics master cases and simple outer mailers with line logos and/or typography.
Litho-Lamination (High-Definition Offset Printing) We print your artwork of the highest quality using our premium German clay-coated white cardboard face stock in our multi-color Heidelberg offset presses. The printed sheet is then laminated to the open corrugated flutes using a permanent adhesive. This is the Industry Standard method for printing high detail such as photographs, also reproducing the finest halftone and color gradients. It also allows for high end finish such as spot UV, matte lamination and hot foil stamping, ideal for electronics boxes, subscription boxes and countertop point of sale displays.
