The role of logistics packaging is to ensure that products are fully protected in the four major links of first-haul transportation, in-warehouse operations, tail-haul logistics and return reverse logistics. In order to avoid a series of problems such as package loss, package damage, and cargo damage, you need to understand these logistics packaging knowledge. Quick Facts Primer: “Minimum Compliance Size” and “Most Economical Package Size” Practical articles: the selection of logistics outer packaging boxes Tips Getting Started “Minimum Compliant Size” and “Most Economical Package Size” Cross-border e-commerce sellers should pay attention to two logistics packaging concepts in practice, namely “minimum compliance size” and “most economical packaging size”. Minimum compliant size “Minimum Compliance Size” means: The total weight of light and small products including packaging should be greater than or equal to 20 grams The longest side of the package should be greater than or equal to 11 cm The second longest side including the package should be greater than or equal to 8 cm When the weight and size of the shipment reaches this standard, the probability of the package being stuck or lost on the automatic sorting equipment on the logistics channel side will be significantly reduced. Most economical package size “The most economical packaging size” means: when the shipment needs to use a logistics channel that calculates the volumetric weight, the design of the product packaging should fully consider the volumetric weight coefficient of the logistics channel. Without compromising product safety, try to reduce the size of product packaging, and try to avoid the occurrence of the longest side triggering the over-length and over-standard surcharges for tail-haul logistics. Actual combat Selection of logistics outer packaging Most of the logistics outer packaging boxes are corrugated boxes, and their quality is mainly affected by the following three factors (in order of importance): wattage, gram weight, and corrugated type. Typically, when the carton sizes are the same: Double-tile (five-layer) cartons are stronger than single-tile (three-layer) cartons; Under the same wattage, the heavier the paper weight, the heavier the carton and the better the quality; Under the same gram weight, the larger the corrugated shape, the thicker the thickness and the better the load-bearing capacity. corrugated carton There are four types of conventional corrugated boxes: A corrugated, B corrugated, C corrugated, and E corrugated. A corrugation: The number of corrugations per unit length is small, and the corrugation is high, so it has the characteristics of good elasticity and good shock absorption, and is suitable for products that are fragile and have high requirements for impact and collision. Corrugated B: Contrary to Corrugated A, the number of corrugations per unit length is large and the corrugation is low. It is suitable for products that have rigidity and do not require shock absorption and protection properties, such as cans and hardware. C flute: The number of flutes per unit length and the height of flutes are between A flute and B flute. It combines the characteristics of A and B flute types and has sufficient rigidity and shock absorption performance. E flute: Compared with A, B and C flutes, it has the characteristics of being thinner and harder. The surface is flat and the appearance is beautiful, suitable for high-quality printing, and has the effect of commodity display. Small cartons generally use a single tile (three layers), and the flute types are commonly E flute (thickness 1mm), B flute (thickness 2-3mm), and C flute (thickness 3-4mm). Large cartons generally use double tiles (five layers), and the flute types commonly use EB flute (thickness about 4mm), BB flute (thickness about 5-6mm), and BC flute (thickness 6-7mm). In addition, there are three-watt (seven-layer) cartons on the market, which are mainly used for the packaging of heavy goods, such as motorcycles. Carton weight The configuration principle of the weight of the carton is: the weight of the surface paper ≥ the weight of the inner paper ≥ the weight of the C flute ≥ the weight of the B flute ≥ the weight of the core paper. Taking the most commonly used five-layer BC corrugated as an example, the face paper is generally 130g and above, the corrugated paper is generally 120g and above, the inner paper is generally 110g and above, and the core paper is generally 80g and above. Tips The editor reminds cross-border e-commerce companies to pay attention to the following three points when choosing product packaging: 1. The outer packaging should meet the total demand of supply chain operations Cross-border e-commerce companies should fully consider their overall needs in the four major links of first-haul transportation, in-warehouse operations, last-haul logistics and return reverse logistics when choosing outer packaging specifications. Once the outer packaging is cracked, its pressure bearing capacity will be greatly reduced. From the warehouse to the reverse logistics of returns, goods will experience multiple moves, weights, and changes in temperature and humidity. 2. Packaging size is not the bigger the better The goods and the carton are under pressure together to avoid gaps (especially height) in order to maximize the vertical bearing capacity. Specifically: In the process of stacking and stacking, the cartons are not in one-to-one correspondence between the edges and corrugations. If there is a gap in the height, the pressure will be unstable and lead to collapse; In the process of ocean transportation and transshipment, the carton is not in a static state, so the size of the goods and the carton needs to be just right to avoid shaking and increase the parallel tension. 3. The weight of the box is not the heavier the better The outer packaging box is a single consumable item. The heavier the carton, the higher the shipping fee, and it is easy to increase the extra cost. Proper selection of cartons can not only meet the needs of transportation but also save costs.
