1. First of all, it is necessary to investigate whether the manufacturer is standard and reliable.
In fact, the hollow board industry is not as high in brand value as other FMCG products, so it has no uniform price standard. Therefore, it is important to look at the pre-sales and after-sales service and credibility. If there is a problem, can the manufacturer solve it in time.

2. Compare the samples based on price.
Many of our customers like to compare prices in the first place. The correct approach should be to inform the manufacturer of the size, thickness, weight, color, and use, and then let the manufacturer send you the appropriate sample. After seeing the actual samples, you can compare price with the same size, thickness, gram/m2 and color.

3. How to identify the quality of hollow board
First, pinch: The poor quality board is also lower in hardness The edge is easy to be depressed when gently pinched by hand.
Second, See: look at the gloss of the board surface, and the condition of the cross section.
Third, Test: you can weigh the sample, the weight per square meters is the GSM of the board.
