What are the specific applications of different types of industrial paper products in logistics scenarios?

In the logistics scene, the core of different types of industrial paper products is to focus on the three goals of "protecting goods, improving efficiency and adapting to the transportation environment", and provide differentiated packaging solutions according to the differences of goods characteristics (weight, vulnerability and form) and logistics links (warehousing, transportation and loading and unloading). The specific applications are as follows:

1. Corrugated paper box: "basic universal" packaging for logistics scenes, suitable for most ordinary goods.

Corrugated paper boxes are the most widely used industrial paper products in logistics because of their low cost, folding and easy customization, and they are suitable for goods with different weights according to their shapes and layers.

1. Single corrugated box (3 layers, mostly B/E corrugated)

Core features: light weight (50-200g per container), low cost (0.5-2 yuan per unit), bursting strength of 1200-1500kPa, suitable for light and small goods.

Specific application scenarios:

E-commerce small logistics: such as clothing, accessories and small household appliances (weight < 5 kg), which can be directly used as transportation packaging, with bubble paper (auxiliary buffering) or kraft paper (filling gaps) in the box;

Factory internal turnover: for example, small hardware parts and plastic components can be reused for 2-3 times in the workshop, and can be recycled after being damaged;

Combined packaging liner: As the internal compartment of large goods (such as household appliances), it separates different accessories (such as remote controllers and manuals) to avoid collision.

2. Double corrugated boxes (5 layers, mostly AB/BC corrugated boxes)

Core features: Strong compression resistance (30-50kn/m for empty containers), impact resistance, bearing 5-20kg, suitable for medium and heavy goods.

Specific application scenarios:

Household appliances logistics: such as rice cookers and microwave ovens (weight 10-15kg), which are used as the outer packaging, and are internally matched with pulp molded lining (to fix the fuselage and cushion the transportation impact);

Transportation of mechanical parts: such as small motors and gearboxes (weight 15-20kg), warning signs of "moisture-proof" and "fragile" can be printed outside the boxes, which is suitable for long-distance road or railway transportation;

E-commerce large packaging: such as treadmills, small furniture (weight 20-30kg, box corners need to be reinforced), and the box body should be reinforced with a strap cross to prevent cracking during loading and unloading.

3. Three corrugated boxes (7 floors, mostly ABC corrugated boxes)

Core features: Super compression resistance (empty container compression resistance 50-80kn/m), puncture resistance, bearing 20-50kg, suitable for heavy goods.

Specific application scenarios:

Industrial equipment logistics: such as small machine tools and generators (weight 30-50kg), the box thickness is ≥15mm, and the bottom of the box is made of reinforced cardboard (bearing double), which is suitable for forklift loading and unloading;

Heavy hardware transportation: such as large bearings and steel structure fittings (weight 20-40kg), which can be stacked in 3-4 layers to save warehouse space;

Cross-border shipping packaging: in the face of long-distance bumps and humid environment, it can be waterproof with plastic film (PE film on the surface) to prevent seawater or rainwater from penetrating.

2. Honeycomb cardboard/honeycomb products: the "heavy+environmental protection" packaging is the first choice for logistics, replacing wood/plastic.

Honeycomb products (honeycomb cardboard, honeycomb pallet and honeycomb carton) are suitable for heavy cargo transportation and scenes with high environmental requirements because of their strong compression resistance, light weight and recyclability.

1. Honeycomb cardboard (thickness 5-50mm)

Core features: It is 30% lighter than corrugated paper with the same thickness, and its plane compressive strength is 2-3 times that of corrugated paper. It can be cut and bent into customized shapes.

Specific application scenarios:

Cushioning of heavy goods: such as transport packaging of refrigerators and washing machines (weight 50-80kg), the periphery of the fuselage is wrapped with 20-30mm thick honeycomb cardboard to replace EPS foam and reduce white pollution;

Pallet pad: as a "buffer layer" of wood/plastic pallets, it is placed under metal plates and glass panels to prevent sliding or scratching during transportation;

Warehouse partition: cut into long honeycomb cardboard, used for partition of goods in warehouse, light and easy to assemble, and can be disassembled repeatedly.

2. Honeycomb tray (bearing 100-500kg)

Core features: the weight is only 1/3 of the wooden pallet (the weight of a single pallet is 5-10kg), and there is no risk of moth (no fumigation), so it is suitable for export logistics.

Specific application scenarios:

Transportation of export goods: if furniture and mechanical parts are exported to the EU and the United States, wooden pallets will be replaced by honeycomb pallets (fumigation-free, saving customs clearance time) with a load of 300-400 kg;

E-commerce promotes warehousing: during the "Double Eleven" and "618" period, household appliances and daily necessities are stacked with honeycomb pallets (stacking height is 2-3 meters), which is light and easy to carry, reducing the intensity of forklift operation;

Logistics in food industry: For example, the whole container transportation of beverages, grain and oil, the honeycomb pallet can be recycled (in line with the environmental protection requirements of the food industry) to avoid sawdust pollution of wooden pallets.

3. honeycomb carton (customized size)

Core features: totally enclosed structure, the compression resistance far exceeds that of corrugated box (the compression resistance of empty box is 80-120 kn/m), and the lining can be customized (fitting the outline of goods).

Specific application scenarios:

Logistics of precision instruments: such as medical equipment and laboratory instruments (weighing 20-30kg, afraid of vibration), with honeycomb carton+custom-made pulp molded lining, which has strong cushioning property, and the displacement of instruments during transportation is ≤ 1 mm;

Exports of heavy household appliances: such as air-conditioning outdoor machines and drum washing machines (weight 30-50kg), honeycomb carton can withstand sea bumps, and honeycomb cardboard partitions are used for lining to prevent internal parts from loosening;

Bulk transportation of fragile articles: such as ceramic tableware and glass lamps (packaged in bulk), and some compartments in honeycomb carton (with one piece of goods in each compartment) are separated and buffered, and the breakage rate can be reduced to below 0.1%.

3. Pulp molded products: the first choice for "fine buffering" of logistics, suitable for abnormal/fragile goods.

Pulp molding takes waste paper as raw material, which can be pressed into any shape, can closely fit goods, and is suitable for protecting abnormal, fragile or high-precision goods without buffer dead angle.

1. Small buffer liner (weight 5-50g)

Core characteristics: the shape matches the goods 1:1, with good cushioning (cushioning coefficient 0.3-0.5), replacing EPS foam, which is environmentally friendly and degradable.

Specific application scenarios:

Logistics of electronic components: such as mobile phone chargers, earphones and chips, are fixed in corrugated boxes with pulp molded liners, and each component has an independent groove to avoid collision and wear during transportation;

Medical device packaging: such as syringes and scalpels (aseptic requirements), pulp molding is used as internal packaging after sterilization to prevent rust or pollution of devices;

Cosmetic logistics: for example, lipstick and essence in glass bottles, the molded paper pulp lining wraps the bottle body, and the top and bottom are provided with raised buffers to prevent the bottle body from breaking when falling.

2. Medium-sized positioning tray (weight 50-200g)

Core features: Multi-groove design can fix multiple small goods at the same time, improving loading and unloading efficiency.

Specific application scenarios:

Automobile parts logistics: such as automobile sensors and connectors (transported to the assembly plant after mass production), molded pallets (20-30 pieces per tray) with accurate positioning and convenient automatic sorting;

Packaging of small household appliances accessories: such as rice cooker liner, soymilk machine blade, paper pulp molded tray partition accessories, to avoid scratches caused by mutual friction during transportation;

E-commerce small package: for example, the "combined order" of multiple pieces of jewelry and stationery, the pulp molding tray is designed with grooves according to the order requirements, and all the small pieces are packed at one time, thus reducing the amount of packaging materials.

3. Large customized lining (weight 200-1000g)

Core features: It is suitable for large-scale special-shaped goods, such as the fuselage of household appliances and furniture accessories, and can be used with honeycomb carton/corrugated boxes.

Specific application scenarios:

Body protection of household appliances: such as TV screen and notebook computer shell, the paper pulp molded lining wraps around the screen, and there are buffer bumps at the top and bottom to prevent the screen from being crushed during transportation;

Logistics of furniture accessories: such as handrails and table legs of solid wood chairs (special-shaped and afraid of scratching), pulp molded lining conforms to the outline of accessories, and the surface is smooth and burr-free, so as to avoid scratching the painted surface;

Lining of precision instruments: such as the fuselage of projectors and printers, the interface and the groove of buttons are reserved for pulp molding lining to prevent the buttons from being damaged by pressing during transportation.

Four, other industrial paper products: logistics "auxiliary support" role, improve process efficiency.

In addition to the core packaging paper products, auxiliary industrial paper products (release paper, label paper and wiping paper) can optimize the logistics process and reduce operational errors, although they do not directly protect the goods.

1. Release paper (for adhesive tape/label carrier)

Application scenario: In the production of logistics labels, release paper, as the carrier of self-adhesive labels, can be peeled off after being attached to the surface of corrugated boxes, which is convenient for scanning (such as the backing paper of express delivery sheets);

Advantages: easy peeling, no residual adhesive layer, adapting to automatic labeling machine, improving the labeling efficiency of e-commerce logistics (labeling 50-100 pieces per minute).

2. Logistics label paper (high temperature/oil resistance)

Application scenario:

Logistics in high-temperature environment: For transportation of automobile parts (engines and exhaust pipes), use high-temperature resistant label paper (resistant to 150℃) to mark the part model and batch to avoid label falling off due to high temperature;

Oil-stained goods packaging: such as mechanical parts and bearings (with anti-rust oil), use oil-resistant label paper, the ink will not smudge, and the scanning recognition rate is ≥ 99%;

Advantages: adapt to different logistics environments, ensure the traceability of goods information, and reduce wrong delivery and missed delivery.

3. Industrial wiping paper (for handling/sorting cleaning)

Application scenario: logistics sorting center and warehouse loading and unloading area are used to wipe the dust and oil stains on the surface of goods (such as antirust oil of metal parts and stains on the surface of cartons) to avoid polluting other goods;

Advantages: strong water absorption (oil absorption is 8-10 times of self-weight), not easy to lose hair, no residue after wiping, and improve the cleanliness of goods delivery.
