Kertas abu-abu ganda adalah jenis kertas kemasan yang umum digunakan. It is a composite cardboard bonded by two layers of gray board paper. It has high strength and rigidity, and is widely used in packaging, pencetakan, making folders and other fields.

Kinerja deteksi
The performance test of double gray paper usually includes the following aspects:

Detection of base weight: The base weight per square meter is calculated by weighing the weight of a double-gray paper sample of a certain size. Timbangan atau timbangan elektronik presisi biasanya digunakan untuk menimbang.

Deteksi ketebalan dan keseragaman: The thickness of double grey paper is measured by using manual or automatic thickness gauge, and the uniformity is detected by laser measurement or machine measurement method. Alat pengukur ketebalan manual biasanya menggunakan alat ukur ketebalan genggam, pengukur ketebalan otomatis biasanya menggunakan triangulasi laser untuk mengukur ketebalan, dan metode pendeteksian keseragaman dapat dilakukan dengan menggunakan sistem visi mesin.
