Yondo Corrugated Plastic Products Ltd

Thickness and GSM are two important factors that affect the performance, weight, and cost of corrugated plastic sheets. For different applications, customers may require specific thickness and GSM specifications, so consistent production control is essential to achieving reliable quality.

As a direct manufacturer of PP corrugated plastic sheets, we control thickness and GSM throughout the production process. The production starts with carefully selected PP raw materials, followed by extrusion and forming. During production, key parameters such as material flow, temperature, and extrusion speed are monitored and adjusted to help maintain stable sheet thickness and weight.

Thickness and GSM are closely related, but they are not exactly the same. A sheet with the same thickness can have different GSM depending on its structure and material distribution. Therefore, both specifications need to be checked rather than relying on thickness alone. Our quality control process includes measuring sheet thickness and weighing samples to verify the actual GSM against the required specification.

Production conditions can also affect the final result. Factors such as raw material composition, extrusion temperature, machine speed, and sheet structure may cause variations if they are not properly controlled. By monitoring these factors during production, we can reduce unnecessary variation and provide more consistent sheets from batch to batch.

Different applications require different combinations of thickness and GSM. For example, lightweight sheets may be suitable for temporary signs and simple packaging, while higher-GSM sheets can provide additional rigidity and durability for industrial dividers, protective sheets, and reusable packaging.

Mantis provides PP corrugated plastic sheets in different thicknesses, GSM, colors, sizes, and customized specifications. With in-house production and quality control, we can adjust the sheet structure according to specific application requirements and help customers find a suitable balance between performance, weight, and cost.
