عربىWhen designing paper carton, reasonable cushioning materials and structural design are essential, especially in preventing items from being shaken and impacted during transportation. During transportation, the items in the carton may be subjected to external forces such as vibration, compression, and impact. If these forces are not effectively buffered, they may cause damage to the items. Therefore, by selecting suitable cushioning materials and optimizing the carton structure design, the items can be effectively protected.
The main function of cushioning materials is to absorb and disperse impact forces, reduce the pressure on items, and avoid damage. Common cushioning materials are:
EPS foam is widely used to protect fragile items such as electronic products, glass products, etc. Its advantages are lightness, pressure resistance, and heat insulation, and it can effectively absorb impact forces and prevent vibration. Its disadvantage is that it is non-degradable, so it is less environmentally friendly.
Polyurethane foam is more elastic than EPS foam, can better relieve vibration and impact, and is suitable for the packaging of high-value products. It does not harden when under pressure and maintains a good protective effect.
Bubble film is a transparent plastic film containing small bubbles that can provide good cushioning protection for items. It is suitable for packaging items with smooth and easily scratched surfaces, such as electronic products, mirrors, ceramic products, etc.
By using structures such as corrugated paper sheets or paper tubes, cushioning protection can be provided for items in the carton. The strength and elasticity of corrugated paper can effectively disperse external impact forces. Corrugated paper of different thicknesses and types can provide different compression resistance and cushioning effects according to needs.
Paper scraps or shredded paper are also widely used as cushioning materials, especially for the packaging of lightweight items. Paper scraps can fill gaps, reduce the movement of items in the carton, and avoid the impact of impact and vibration on items.
This material is often used for the packaging of high-end or heavy items. It is formed by soaking pulp and forming a mold with a specific shape. Pulp molding has strong elasticity, can absorb external impact forces and provide stable support.
Air cushion bags are a kind of film bags that can provide cushioning protection for products by sealing gas. It is characterized by being light and easy to customize, suitable for the packaging of small items. Air cushion bags have good impact resistance and can effectively reduce shock and prevent damage to items.
Air bags are made of soft plastic materials and are filled with air inside. Its cushioning effect is similar to that of air cushion bags, which is suitable for packaging most electronic products or small items, and has high recyclability and environmental protection.
In addition to the choice of cushioning materials, the structural design of the carton itself also plays an important role in alleviating vibration and impact. The following are some common design methods:
The number of layers of the corrugated box determines its compression resistance and cushioning effect. Single-wall corrugated boxes are suitable for packaging light items, while double-wall and triple-wall corrugated boxes are suitable for packaging heavy items. The middle part of each layer of corrugated paper is filled with air, which can absorb part of the impact force, so thicker corrugated boxes usually have better impact resistance.
The thicker the carton, the stronger its compression resistance. When designing, according to the weight of the items and the mode of transportation, the thickness of the carton should be reasonably selected to improve its protection against vibration and compression.
Adding paper dividers or interlayers inside the carton can separate the items and prevent them from colliding with each other. This design is particularly suitable for packaging fragile or irregularly shaped items. The interlayer not only prevents items from contacting each other, but also reduces the impact of vibration on the items.
Some cartons can also be designed with lining structures, such as lining foam, foam board or bubble film. Through these lining materials, the items in the carton can get more cushioning protection when they are subjected to external impact.
The corners and edges of the carton are the most vulnerable to impact. Adding reinforcement design (such as thickened cardboard, foam corner pads, etc.) to these parts can effectively increase the strength of the carton and avoid damage during handling and transportation.
The bottom is the main part of the carton that bears gravity and pressure, and usually requires reinforcement design. Adding extra layers or using thickened materials at the bottom can improve the carton's ability to resist pressure and reduce damage during transportation.
For some items that need ventilation (such as food, electronic products, etc.), vents can be added to the carton design to help air circulation. This not only helps keep the items dry, but also reduces the risk of damage to the items when the humidity changes.
Using cardboard materials with good air permeability can help regulate the temperature and humidity inside the carton and reduce the impact of climate change on the items during transportation.
The cushioning material and structural design in the carton design are important factors to ensure that the items are not shaken and impacted during transportation. By rationally selecting cushioning materials (such as foam, air cushion, corrugated paper, etc.) and optimizing the structural design of cartons (such as partitions, reinforced corners, etc.), the protective performance of cartons can be effectively improved to ensure that items arrive safely at their destination. At the same time, in combination with environmental protection requirements, recyclable and degradable materials can be selected to further improve the sustainability of packaging.
