Carton shockproof packaging, also known as cushioning packaging, plays an important role in various packaging methods. The product is placed in a different environment from the production to the start of use through a series of transportation, storage, stacking and loading and unloading processes. In any environment, it will force the product and cause mechanical damage. In order to prevent damage to the product, it is necessary to reduce the impact of external forces. The so-called shockproof packaging refers to the packaging to reduce the shock and vibration of the contents and protect them from damage. Common cushioning packaging materials are foam plastic, honeycomb paperboard, pulp molding, corrugated cardboard, paper, air cushion and vegetable fiber packaging cushioning materials. Due to the modern packaging slowdown; many of the materials are single-use, many countries and regions have made higher regulations on environmental protection, which has led to the further development of green buffer packaging, and there have also been many green packaging materials, such as: Shredded paper, crepe paper, corrugated board, pulp molded, degradable plastic, honeycomb paperboard, etc. In the design of the carton structure, how do products with anti-vibration requirements use shock-proof technology for packaging? The main requirements of customers When investigating customers, we will always encounter different shapes of products, such as auto parts and other individual product weights. Very high, there are also fragile items such as glass products. The requirements of the customers are also different. The main requirements are as follows:
Reduce costs (some other packaging such as wooden boxes are expected to be replaced by cartons);
The storage and transportation cycle is too long, and it is necessary to cope with the decay of the strength of the carton during long-term storage and transportation;
The impact of the warehouse environment on the stacking code. To, require the carton to have a higher pressure resistance;
Environmental protection requirements (such as some foamed plastics need other environmentally friendly products to replace);
Transportation and sales packaging are integrated;
The effect of packing speed;
More specifications, integrated packaging and so on. The main aspects of the seismic design are to ensure that the strength of the carton itself can cope with the damage caused in the storage and transportation environment, which requires a comprehensive design and simulation test of the carton to achieve effective protection of the product. When designing the carton structure, there are mainly the following aspects in dealing with the carton shockproof:
Corrugated gaskets: Gaskets are the most common type of protection against resonance and damage caused by medium impact during carton transportation. And the gasket structure is simple, easy to produce, and is especially suitable for the protection of some regular shape products.
Corrugated grille: The grille is used for the separation of small items and is generally used together with cartons. The design of the carton barrier must be compact, and the effective product is fixed in the grille so that it does not collide. When used for packaging metal coated articles, the effect is remarkable. A suitable corrugated barrier can also increase the compressive strength of the carton. Of course, the grille of the carton is also used to separate the items, which is more cost-effective than packaging the individual products.
Corner protection: The corners of the carton are developed in a wide variety of styles, with folded corners and bonded corners. Generally, the corners are combined with the product according to the appearance of the product. Many products that use corner protectors are of higher quality, so the overall pressure and resistance of the carton, the impact of the medium impact and resonance should be considered in the design.
Single-faced corrugated paper: It is a type of packaging paper that is used more when packaging glass products. Used together with the carton corners, the shockproof effect is more significant. It is suitable for the packaging of cylindrical glass products by utilizing the ductility of single-faced corrugated paper. When selecting single-face corrugated paper for product protection, different corrugated types can be adopted according to different product weights, which can effectively prevent the damage caused by resonance to the product.
Hanging packaging carton: For this type of packaging, it can be made of carton with corners, or it can be completely made of corrugated cardboard. Due to its unique structural design, this type of carton can provide a similar suspension space in the carton, which can effectively deal with the damage caused by the product in the transportation environment.
This type of carton can be used both as a shipping package for cartons and as a sales package for cartons. Because of its high cost, it is suitable for the packaging of products with higher added value.
When designing the structure of the carton, no matter which type of carton is used, the six-step method of carton structure design must be followed. That is to conduct a comprehensive survey of customers, master the logistics and storage and transportation environment; use appropriate materials and types of protection in the design. After the design is completed, the sample box needs to be tested such as resonance, drop and compression. The simulation simulates the environmental hazard of the product during storage and transportation, and checks whether the product can be effectively protected. Both the product must be effectively protected and the product must be over-packaged. Also consider the cost in the design.
