Can

"Can" in foreign trade specifically refers to a packaging method in which goods are sealed in metal cans (such as tinplate cans or aluminum cans). It is commonly used for food (luncheon meat, canned fruit), chemicals (paints, inks), and certain dangerous goods. Usage scenarios: 1) Suitable for products requiring long shelf life, moisture protection, oxidation prevention, or leakage prevention; 2) In sea or air transport, canned goods often need to be combined with pallets and carton outer packaging to meet transport and stacking requirements; 3) Canned dangerous goods must comply with rules such as IMDG and IATA, use UN-certified cans, and bear dangerous goods labels. Precautions: 1) The can body material, capacity, sealing grade, and whether an inner coating is required must be specified; 2) Attention must be paid to regulations in the destination country on food-contact materials and heavy metal migration (such as FDA, EU 1935/2004); 3) Cans may swell due to temperature changes, so headspace must be reserved. Difference from "Drum": cans have small capacity (usually ≤20L), while drums have large capacity (often 200L); difference from "Bottle": cans are mostly made of metal, while bottles are mostly glass or plastic, and cans have stronger sealing and pressure resistance.
