Protection performance: Express foam bags should have good protection performance, which can effectively prevent the damage of external forces such as squeezing, vibration, friction during transportation during transportation. The foam bags should have a certain ability to resist impact and shock absorption to reduce the possibility of damage to items.
Material quality: Express foam bags should be made of high -quality materials. They have good durability and strength, and can withstand greater pressure and friction. At the same time, the materials should have the performance of moisture -proof and waterproof to maintain the drying and cleaning of the items.
Insulation performance: If the express delivery needs to be transported for a long time or is a region with a large difference in temperature, the courier foam bag should have good thermal insulation performance, which can maintain the temperature of the items stable and avoid damage caused by temperature changes.
Environmental performance: Express foam bags should be made of environmentally friendly materials, which can be recovered and reused. At the same time, foam bags should have non -toxic and harmless characteristics, and will not cause harm to items and the human body.
Easy to operate: Express foam bags should be easy to operate, which is convenient for packaging and sealing. At the same time, foam bags should also have the characteristics such as anti -adhesion and self -adhesion, which can ensure the stability and firmness of the packaging.
Cost benefits: The cost of express foam bags should be relatively low, which can meet the needs of large -scale production and use. At the same time, the quality and performance of foam bags should be consistent with its price to achieve good cost benefits.
In summary, the quality and performance standards of express foam bags mainly include protective performance, material quality, thermal insulation performance, environmental protection performance, operating convenience and cost benefits. These standards are of great significance to ensure the safety, stability, fast and environmental protection of express delivery.
