Corrugated carton shockproof design

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 structural design of carton, how to use shockproof technology to package products with shockproof requirements?

The main requirements of the customer

When conducting research on customers, we will always encounter products with various shapes, such as parts and components of automobiles that have high weight, as well as 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 seismic design

To ensure that the strength of the carton itself can deal with the harm caused by the storage and transportation environment, it is necessary to conduct a comprehensive design and simulation test on the carton so as to effectively protect the product. In the design of the carton structure, there are mainly the following aspects in response to carton shockproof:

Corrugated gasket:

Gaskets are the most common type of response to resonance in cartons, and protection against damage 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:

Grids are used for the separation of small items and are generally used 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 carton are developed in a wide variety of shapes, including folded corners and bonded 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.

Hanging empty carton:

For this type of packaging, it can be made of cartons with protective corners, or it 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.
