EVA storage packaging box customized shock resistant and pressure resistant multi specification electronic product instrument protection box

Description :

  EVA storage packaging box is a high-density cushioning packaging container made of ethylene vinyl acetate copolymer (EVA) material, which is molded or cut into shape. It mainly solves the problem of damage caused by collision and vibration during transportation and storage of precision instruments, electronic products, hardware tools, etc. Typical operating conditions include express logistics transfer, internal factory turnover, and terminal retail display. This category has the characteristics of lightweight, high rebound, and chemical corrosion resistance, and is suitable for packaging various small and medium-sized items with high requirements for shock and moisture resistance. It can effectively improve the integrity rate of product delivery.

  The specifications and dimensions of EVA storage packaging boxes can be customized according to the shape of the contents. The common thickness range is between 10mm and 50mm, and the hardness is usually controlled at 35-55 degrees to balance cushioning and support. The surface of the material can be treated with processes such as flocking, embossing, and screen printing to enhance its appearance texture and brand recognition. The executive standards refer to GB/T 6343 Density Measurement of Foam Plastics and GB/T 8813 Compression Performance Test of Rigid Foam Plastics. High quality products should have no odor, no falling debris, neat edge cutting, and a tight fit between the inner groove and the product to ensure a fixed effect.

  When selecting EVA storage packaging boxes, it is necessary to clarify the weight, size, and fragility of the contents. High density EVA is suitable for heavy or sharp objects, while low-density is suitable for lightweight electronic components. If waterproof and dustproof are required, it is recommended to choose a one-piece box shell with zipper or buckle and EVA lining. Compared with ordinary pearl cotton (EPE), EVA has higher hardness and better shaping effect, but the cost is slightly higher; Compared to sponge, EVA is more wear-resistant and less prone to deformation. For irregularly shaped items, it is recommended to provide 3D drawings or physical samples for precise mold opening to avoid large gaps that may cause shaking.

  EVA storage packaging box is easy to install and use, simply insert items into the preset groove. In daily maintenance, prolonged direct sunlight should be avoided to prevent material aging and yellowing. When cleaning, wipe the surface dust with a damp cloth and do not use strong solvents. The typical usage cycle depends on the frequency of use and environment, and can generally be reused dozens to hundreds of times. Common faults include lining collapse or edge cracking, often caused by overloading or severe drops. If damage is found, it should be replaced in a timely manner to ensure protective performance. When stored, it should be placed in a cool and dry place to prevent moisture and mold.
