This paper aims at the problems of low material reuse rate, low storage space utilization, and insufficient environmental protection in the existing electronic product buffer packaging, to design a green packaging with a film fastening structure for light and small products. A TPU plastic film with good performance is pasted on a piece of corrugated cardboard with water-based adhesive and folded to form a packaging with a film fastening structure. The selection criteria of the substrate is determined by measuring the physical properties of the cardboard and film. Accelerated aging test, drop and vibration test are carried out on the film fastening package to verify the reliability of the film fastening package. The curing process of the glue has a certain effect on the peeling strength of the film. The film composite packaging has good reliability at room temperature, and the bonding strength of the glue will be reduced to varying degrees under the conditions of alternating high and low temperatures. The test results of drop and vibration show that the appearance and function of the sample are not damaged, and the film tight packaging can meet the requirements of vibration and drop impact protection during transportation. High-reliability film fastening packaging needs to meet the requirements that when peeling at 180°, the peeling force is not less than 20 N and when peeling at 0°, the peeling force is not less than 80 N. This film fastening packaging can significantly reduce packaging volume and save storage and logistics costs, has good recyclability and degradable TPU, and is easy to be reprocessed and recycled. It can meet transportation requirements and provide cost-reducing and environmentally-friendly buffer packaging for electronic product design ideas.
