Compared with traditional single-layer paper tubes, this shockproof packaging tube has a three-layer composite structure, with the corrugated paper core providing good buffer performance and the EPE pearl cotton lining further enhancing shock absorption, with a shock absorption efficiency of up to 85%. It meets the ISTA 3A transportation safety standard, effectively protecting products from damage caused by drop and extrusion during transportation. The foam plug sealing design provides good dust resistance, and the smooth inner wall will not scratch the surface of precision instruments. It is made of non-toxic and odorless materials, cause pollution to precision instruments, and can be recycled after use.
The product has an optional inner diameter range of 30-150mm, standard length of 200-1500mm, and wall thickness of 3-6mm. The shock absorption efficiency can be adjusted up to 90% according to customer needs, and the EPE pearl cotton lining thickness can be customized from 5mm to 10mm. It meets the ISTA 3A transportation testing standard, and the outer layer can be coated with anti-static coating to prevent static damage to electronic components. The size precision is ±1mm, ensuring that the packaged product fits tightly in the tube, avoiding shaking and displacement during transportation. The product can be customized with printing patterns and anti-static treatment according to customer needs.
This shockproof packaging paper tube is mainly applicable to the transportation and storage of optical lenses, circuit boards, precision hardware, laboratory instruments and other precision products. It is widely used in electronic manufacturing, aerospace accessories, optical equipment manufacturing and precision instrument maintenance industries. It can also be used as a protective sleeve for precision rods and slender products, providing efficient protection during transportation and storage.
