Shockproof packaging, also called cushioning packaging, occupies an important position in various packaging methods. Products from production to the beginning of use through a series of transport, storage, stacking and loading and unloading process, placed in a different environment. In any environment will have a strong role in the product, and make the product mechanical damage. In order to prevent damage to the product, we must try to reduce the impact of external forces. The so-called shock-proof packaging refers to the package used to slow down the shock and vibration of the contents and protect them against damage. Common cushioning packaging materials include foam plastic, honeycomb paperboard, pulp molding, corrugated board, paper type, air cushion and plant fiber packaging cushioning materials. As modern packaging is slow; many Chinese materials are used once, many countries and regions have made higher regulations for environmental protection, prompting the further development of green buffer packaging, and there are also many green packaging materials, such as: Shredding, crepe paper, corrugated board, pulp molding, degradable plastics, honeycomb paperboard, etc. In the carton structural design, how to use shockproof technology to package products with shockproof requirements? Customer's main requirements When we are conducting research on customers, we will always encounter different shapes of products, existing car parts, and other individual product weights. Very high, there are also fragile items such as glass products. The customer's requirements are also not the same. The main requirements are:
â– Reduce costs (some other packaging, such as wooden boxes, are expected to be replaced by cartons);
â– The storage and transportation cycle is too long and it is necessary to cope with the decay of the strength of the carton in the long-term storage and transportation process;
â– Warehouse environment impact on stacking. Towards, the carton is required to have a higher pressure resistance;
â– Environmental requirements (such as some foam plastics need other environmental protection products instead);
â– Integration of transportation and sales packaging;
â– Influence of packing speed;
â– More specifications, integrated packing boxes and so on. The main aspects of the shockproof design must ensure that the strength of the carton itself can deal with the damage caused in the storage and transportation environment. This requires a comprehensive design and simulation test of the carton in order to effectively protect the product. In the carton structure design, there are mainly the following aspects of carton shockproof: Corrugated gasket: The gasket is the most common one in the carton transport process to deal with resonance and the protective measures that the hitting will cause harm to the product. The gasket has a simple structure and is easy to produce, and is particularly suitable for the protection of some products with a relatively regular shape. Corrugated grille: The grille is used for the separation of small items and is generally used together with cartons. The design of the carton grille must be compact, and the effective fixed product is in the grille so that it does not collide. When used for the packaging of metal coated articles, the effect is remarkable. Proper corrugated louvers can also increase the compressive strength of the carton ensemble. Of course, the slats of the carton are also used to separate the items, which is more cost-effective than packaging individual products. Corner protection: The corners of the development of the carton are various, with folded corners and adhesive corners. It is generally designed according to the shape of the appearance of the product and the product combined with the corner. Many products that use kerfs are high quality products. Therefore, the overall pressure and resistance of the carton must be taken into consideration in the design process; the impact of mid-stroke and resonance should be taken into consideration. Single-sided corrugated paper: It is a kind of packaging paper that is used more often when packaging glass products. Together with carton corners, the shockproof effect is even more pronounced. The use of single-sided corrugated paper's ductility is suitable for packaging cylinder-shaped glass products. When selecting single-faced corrugated paper for product protection, different corrugated types can be adopted according to different product weights, which can effectively prevent resonance from harming the product. Suspended packaging cartons: For this type of packaging, cartons can be made with corners, or can be completely boxed with corrugated cardboard. Due to its unique structural design, this kind of carton can enable the product to get a similar suspended space in the carton, which can effectively deal with the damage caused by the product in the transport environment. This kind of carton can be used both as a transport package for cartons and as a sales package for cartons. Due to its higher cost, it is suitable for packaging of products with higher added value. In the structural design of the carton, no matter which kind of carton shockproof method is used, must follow the carton structure design six-step method. That is to conduct a comprehensive survey of customers, to master the logistics and storage and transportation environment; the use of appropriate materials and types of protection in the design and so on. After the design is completed, it is necessary to perform tests such as resonance, drop and compression on the sample box, calculate the hazard of the product during storage and transportation, and check whether the product can be effectively protected. It is necessary to effectively protect the product while also preventing excessive packaging of the product. Also consider the cost in the design.
