Film covered pearl cotton printing bag Custom LOGO shockproof packaging White EPE foam bag

Description :

  Coated pearl cotton printing bag is a composite packaging material that combines the cushioning performance of EPE foam material with the surface printing function of woven bags or films. It mainly solves the problems of shock protection and brand display for fragile items, precision instruments, and products with high appearance requirements in logistics transportation. Typical working conditions include electronic product assembly line packaging, hardware accessory export packing, and e-commerce express delivery. This category provides excellent impact resistance through the inner layer of pearl cotton, while the outer layer is coated with waterproof, moisture-proof, and high-definition pattern printing, which not only protects the physical safety of the product, but also enhances the overall beauty and recognition of the packaging. It is a common choice in modern logistics packaging that balances practicality and marketing.

  The core specifications of this product involve substrate thickness, density, and coating process. The thickness of EPE pearl cotton is usually between 1mm and 5mm, with a density range of 18-30kg/m ³. The specific value needs to be adjusted according to the load-bearing requirements. The outer layer of the film is often made of Po or PE material, which is firmly combined with pearl cotton through hot melt composite technology to ensure no delamination or delamination. In terms of printing, it supports gravure printing or silk screen printing, with high color reproduction, and can customize multi-color logos and product information. The implementation standards usually refer to GB/T related packaging material specifications, which have good tear resistance and tensile properties. Edge treatment often uses hot cutting or ultrasonic sealing, with a smooth and lint free cut that meets the environmental testing requirements of most export products, such as the ROHS directive.

  When selecting, it is necessary to clearly distinguish the application differences between ordinary pearl cotton bags and laminated printed bags. If only internal buffering is required and there is no need for external display, the cost of ordinary white pearl cotton bags is lower; If you need an external wear-resistant, waterproof, and branded product, you must choose a laminated version. For heavy mechanical components, it is recommended to increase the thickness of pearl cotton or adopt a multi-layer composite structure; For lightweight electronic components, a thickness of 1-2mm is sufficient to meet protection requirements. Pay attention to the friction coefficient of the film coating layer. If it is used for automated assembly line packaging, it is necessary to confirm whether the surface smoothness is suitable for mechanical grasping. In addition, long-term storage in high temperature environments should be avoided to prevent deformation or adhesion between the film layer and the substrate, which may affect the subsequent use experience.

  In terms of installation and maintenance, laminated pearl cotton printing bags are usually finished bags that can be directly inserted into the product without the need for additional folding or assembly. When using, attention should be paid to the risk of piercing with sharp objects. Although pearl cotton has resilience, sharp objects may still damage the film layer and cause moisture resistance failure. Daily storage should be placed in a cool and dry place, avoiding direct sunlight that can cause the film to age and become brittle or the printed patterns to fade. If layering, damage or severe stains are found on the bag body, it should be replaced in a timely manner to ensure the protective effect. After disposal, due to the presence of plastic film and foam materials, it is recommended to recycle according to local garbage classification standards. Some materials can be professionally processed and reused to reduce environmental burden.
