1. reasonable

1-1. Considering the pressure of pportation process.

1-2. Assembly problem. It can be assembled simply and quickly.

1-3. The load point is loaded with heavy uniformity.

1-4. Size and location of buckle position

Compressive properties of 2-1. materials

Water absorption of 2-2. materials

The physical properties of 2-3. materials are different from the base paper produced by each base paper mill.

Selection of 2-4. material weight

3-1. printing, to minimize pressure on the cardboard, to avoid collapse of corrugated, reduce compression and deformation rate.

The water should be appropriate.

3-2. after printing, surface treatment as far as possible after printing 12 hours later.

The pressure adjustment of die cutting should be appropriate.

After bonding, press firmly and lay aside for a period of time until the glue is dry.

It is also necessary to avoid unstandardized factors such as folding and so on during the production and pportation process.
