After the plastic sheet material such as polyvinyl chloride (PVC), polystyrene (PS), polyethylene (PE), and polypropylene (PP) is heated and softened, it is cooled and shaped by using vacuum adsorption principle and cutting. It provides good protection against shock, collision and scratching. It is convenient to display the appearance of the product due to high transparency, which is beneficial to sales. The production process is simple, the raw material cost is low, and the weight of the blister tray itself is light, which can reduce the production and logistics cost. Some materials can be recycled, which meets the environmental protection trend. Blister tray has a wide range of applications. In the field of electronic appliances, it can prevent static electricity and collision to protect components and small electronic products. In the hardware tool industry, it can ensure that the tools are neat and orderly, and avoid wear and tear. In the toy and food industries, it can protect the products and facilitate display. In the packaging field, it realizes personalized packaging, improves product added value and competitiveness, and reduces loss. In logistics and transportation, lightweight and standardized design improve efficiency and reduce cost. In the aspect of environmental protection, recyclable materials help resource recycling. When displaying products, its beautiful design attracts consumers and promotes sales. With its unique performance and wide application, blister tray plays a key role in various industries and brings important value to production, circulation and consumption.
