Complete Container Loading & Cubic Calculation Guide for Road Marking Materials Export Shipment

 For foreign trade importers and project contractors who purchase road marking materials from Chinese factories in bulk, container cubic volume calculation, pallet stacking layout, mixed loading of different products and container space utilization rate are very practical core procurement knowledge. Unreasonable loading scheme will lead to two major losses: one is that the calculated CBM volume is inaccurate, resulting in the need to book additional small containers and increase ocean freight costs; the other is irregular pallet stacking during loading, which causes the collapse of goods during long-distance sea transportation, resulting in product package breakage, paint damp agglomeration and glass bead bag breakage loss. Road marking supporting products involve multiple categories including bulk powdery hot melt paint, liquid undercoat primer, granular reflective glass beads, barreled MMA two-component paint and bulky construction equipment such as hand push marking machines and heating kettles. The physical state, packaging form, single package size and weight of each product are completely different, and the mixed loading requirements of dangerous goods and ordinary goods also need to be strictly followed to avoid customs declaration risks. As a long-term export road marking material manufacturer, Lumei summarizes the mature and stable container loading scheme of 20GP small containers and 40GP large containers based on thousands of container shipment cases, provides accurate CBM cubic calculation reference data, wooden pallet standard stacking rules and sea freight packaging protection standards, which can be directly used for your container volume budget before ordering and on-site loading supervision during shipment. All products adopt export-grade moisture-proof and tear-resistant packaging, support 1.2m*1.2m standard fumigated wooden pallet stacking, and can flexibly match the mixed loading proportion of various materials according to project construction dosage.

1. Basic Packaging Parameters of All Exportable Road Marking Products (Calculation Basis for CBM) Before container volume calculation, we first clarify the unified outer packing size, single package weight and net content of each product exported by the factory, all data are actual measured values of finished export packaging, which can be directly used for cubic volume accumulation calculation. All packaging is lined with thick plastic inner bags to prevent sea freight damp and rainwater infiltration during transshipment. 1.1 Thermoplastic Road Marking Paint (Powder Solid Coating) Conventional outer package: 25kg per woven bag, outer bag size 0.55m0.45m0.15m, single bag volume 0.037125 CBM. Tropical high temperature resistant upgraded version hot melt paint adopts the same packaging specification, only the internal formula is adjusted, and the outer volume and weight are completely consistent, which is convenient for unified pallet stacking and volume statistics. For OEM customized orders, we can print the customer’s English brand information on the outer woven bags without changing the packaging size, which will not affect the subsequent container loading calculation data.

Each set of MMA paint is matched with one A barrel and one B barrel, and the barrels are placed vertically on the pallet during loading to avoid tipping and liquid leakage caused by horizontal extrusion during transportation. Scratch type and spray type MMA products have the same barrel packaging size, and the volume calculation standard is unified.

The barrel mouth is equipped with anti-leakage pressure-resistant sealing cover, and the outer barrel is wrapped with stretch film to prevent collision and cracking during container loading and unloading. As a liquid auxiliary material, the primer is usually mixed in a small amount in the container with hot melt paint and glass beads, and the occupied volume is small, which can be flexibly arranged in the gap of the pallet. Corresponding page: https://chnlumei.com/products/road-marking-thermoplastic-primer.html. 1.4 Reflective Glass Beads Series Three specifications of glass beads all adopt 25kg woven bag packaging, the outer bag size is completely consistent with hot melt paint bags: 0.55m0.45m0.15m, single bag volume 0.037125 CBM. The granular glass beads have strong fluidity, so the bags need to be stacked flatly on the pallet during loading, and excessive high stacking is prohibited to prevent the bottom packaging bag from being broken by heavy pressure, resulting in bead leakage and container bottom dirt. Internal mixing beads, surface spreading beads and high refractive index rainy night reflective beads can be mixed and stacked on different pallets for easy port sorting by the destination warehouse. Product cluster: https://chnlumei.com/products/reflective-glass-beads-series.html. 1.5 Construction Supporting Equipment Hand push thermoplastic road marking machine and heating preheating stirring kettle adopt carton + wooden frame shockproof packaging, single set overall outer size about 1.1m0.75m0.62m, single set volume about 0.5115 CBM. The equipment belongs to irregular large-volume goods, with heavy dead weight, so it needs to be fixed on the bottom layer of the pallet with binding belts during loading, and the upper layer cannot stack heavy powder bags to avoid extrusion deformation of the metal structure of the equipment. Two types of equipment can be placed at the rear corner of the container, which is convenient for the consignee to unload the pallet first after arriving at the port.

2. Standard Wooden Pallet Stacking Rules (1.2m1.2m Export Fumigated Pallet) All bulk powder bags and barreled liquid materials use international common 1.2m1.2m four-way fork entry fumigated wooden pallets, which meet the port quarantine requirements of all countries and can be directly loaded into containers without quarantine re-inspection. The unified stacking limit rules are formulated according to the bearing capacity of the pallet and the pressure resistance of the packaging: 2.1 Powder Bag Products (Hot Melt Paint + Glass Beads) Single Pallet Stacking Each layer of 1.2*1.2 pallet can horizontally place 6 woven bags neatly, with a total of 6 layers of safe stacking height, a total of 36 bags per pallet. Total weight per pallet: 36 bags 25kg=900kg, which is within the safe load range of the wooden pallet; Total volume per pallet: 360.037125=1.3365 CBM. Each pallet is wrapped with 3 layers of stretch film around the whole circle, and fixed with plastic binding belts at four corners to prevent the bag stack from sliding and collapsing during the container’s bumpy long-distance transportation on the sea. This stacking method is the most commonly used for hot melt paint bulk export orders, with the highest space utilization rate. 2.2 Barreled Liquid Products (MMA Paint + Primer) Pallet Stacking Each layer of the pallet can place 9 round plastic barrels neatly, with a maximum of 2 layers stacked vertically, a total of 18 barrels per pallet, to prevent the upper barrel from collapsing and leaking due to excessive height. Each barrel is clamped with a cardboard partition between layers, and the whole pallet is wrapped tightly with stretch film to fix the barrel body, avoiding mutual collision and breakage during transportation. 2.3 Equipment Wooden Frame Packaging Pallet Placement Each pallet only places one set of marking machine or heating kettle, fixed with iron binding belts on the pallet surface, wrapped with anti-collision bubble film around the wooden frame, and placed at the stable position of the container bottom layer, no other goods are stacked on the upper part of the equipment pallet.

4. Key Precautions for Container Loading to Avoid Sea Freight Losses Many goods damage problems in the process of export sea transportation are caused by non-standard loading operation, and we summarize 8 core loading control points that must be strictly implemented during on-site container stuffing: 4.1 Classify ordinary goods and liquid goods separately for pallet grouping Powder hot melt paint and glass beads are ordinary solid goods, which can be stacked in large quantities in the front and middle of the container; barreled liquid MMA paint and primer are placed in the rear half area of the container, even if a small amount of leakage occurs during transportation, it will not pollute a large number of powder bag goods, reducing the scope of loss. 4.2 Strictly control the stacking height of all pallets The highest point of the pallet stack must be 5cm lower than the inner top height of the container, to avoid the goods being squeezed and damaged by the container top beam during road bumping and sea vessel rolling. 4.3 Fill the gap between pallets with cardboard and wooden blocks Use waste hard cardboard and small wooden strips to plug the loose gaps between adjacent pallets, eliminate the left and right shaking space of the pallet group in the container, and prevent the pallet from shifting and collapsing during the voyage. 4.4 The whole container is reinforced with tension binding belts After all pallets are placed, use heavy-duty tension belts to horizontally and vertically fix the entire pallet group on the container ring fixed points, which is the most effective anti-slip measure for long-distance sea transportation. 4.5 Equipment goods are placed in the rear corner position Irregular heavy equipment such as marking machines and heating kettles are fixed at the two inner corners of the container door, which can be unloaded preferentially when the destination port opens the container door, avoiding the need to move a large number of front pallets first to take out the equipment. 4.6 Do not mix other prohibited dangerous goods in the container Road marking paint belongs to ordinary chemical coatings, which can be declared as general cargo for export, but it is prohibited to mix batteries, flammable solvents and other dangerous goods in the same container, so as not to affect customs clearance and shipping company acceptance. 4.7 Waterproof treatment for container door bottom gap Lay a whole roll of waterproof plastic film on the bottom of the container before pallet entry, and stick the waterproof adhesive strip on the inner side of the container door to prevent rainwater from splashing into the container during port loading and unloading and sea voyage heavy weather. 4.8 Take full photos and videos of the whole loading process Our factory will shoot the whole process video and photos from empty container inspection, pallet entering the container to final door closing and sealing, and send them to the customer for filing, which can be used as claim evidence if goods damage occurs during logistics transportation.
