How China Jumbo Roll Foil Prices Are Built
The ex-factory price of Chinese aluminum foil is essentially the price of aluminum ingot plus a processing fee. Ingot prices move with global and domestic metal markets, so the raw-material component changes frequently, while the processing fee reflects the cost of rolling, annealing, slitting, packaging, and the mill margin. Because of this structure, buyers cannot rely on a fixed price list; suppliers quote one-to-one for each order based on the current ingot price and the specific processing requirements of the customer.
Typical Grades and Specifications
Chinese jumbo roll foil is commonly available in alloys such as 8011, 8021, 3003, and 3004, covering medical foil, pharmaceutical packaging, food-grade foil, and industrial applications. Typical thicknesses range from about 0.01 mm to 0.2 mm, and typical widths range from about 100 mm to 1650 mm, though exact ranges depend on the alloy and the mill equipment. The temper is selected according to the end use, from soft annealed foil for lamination to harder tempers for forming and container applications.
8011 Jumbo Roll Foil and Its Cost Advantage
8011 is the most economical of the common jumbo foil grades, which makes it attractive for high-volume markets. Its typical composition includes about 0.6-1.0% iron and 0.5-0.9% silicon, with small limits on manganese, copper, zinc, titanium, magnesium, and chromium, and the balance aluminum. Foil in this alloy commonly shows tensile strength in the 90-150 MPa range depending on temper, with typical elongation around 13%. Despite the low cost, 8011 offers good strength, toughness, machinability, and forming performance, so it is widely used for food containers, bottle caps, pharmaceutical packaging, household foil, and industrial and electronic applications.
Other Grades: 8021-O, 3003 and 3004
8021-O is a soft annealed grade often chosen for pharmaceutical blister foil and cable wrapping, where flexibility and barrier performance are more important than stiffness. The 3003 and 3004 alloys add manganese, which raises strength while keeping good formability, so they are selected for food containers, trays, and closures that need more rigidity. Each grade carries a different processing cost, so the alloy choice directly affects the quotation. Buyers should specify the grade and its purpose rather than asking for the cheapest option, because using the wrong alloy usually costs more in rejected product and line stoppages.
How to Get an Accurate Quotation
To receive a meaningful price for jumbo foil, provide the supplier with the alloy and temper, thickness, width, inner core diameter, order quantity in metric tons, and the final application. State whether you need plain foil or surface treatment such as printing, embossing, or coating. Ask how the quote is linked to the ingot price, whether it is valid for a defined period, and what happens if the ingot price moves before shipment. A reliable supplier will confirm the specification in writing and provide a sample coil so you can verify gauge, surface, and runnability before production.
FAQ
Why do Chinese jumbo foil prices change so often?
Because the main cost component is aluminum ingot, whose price moves with the metal market. The processing fee is more stable, but the combined quote naturally follows ingot movements.
What is the typical thickness range for jumbo foil?
Chinese jumbo foil is commonly produced from about 0.01 mm to 0.2 mm, with the exact range depending on alloy and mill capability. Household and food foil usually sits at the thinner end.
Why is 8011 jumbo foil cheaper than other grades?
8011 uses economical alloy additions and is produced in very large volumes, which lowers both material and processing cost while still meeting most packaging requirements.
Is the quoted price the final price?
Most Chinese suppliers quote based on ingot price plus processing fee, so the final price is usually adjusted according to the ingot price on the shipment or order date, unless a fixed-price agreement is made.
How long does a jumbo foil quotation remain valid?
Validity typically ranges from one day to one week depending on market volatility. Buyers should confirm the validity period in writing when requesting a quote.
What information should I give to get an accurate quote?
Provide alloy, temper, thickness, width, core size, quantity, and end application. The more precise the specification, the more accurate and stable the quotation will be.
Q: Why do Chinese jumbo foil prices change so often?
Foil price follows the Shanghai Futures Exchange aluminum price plus the foil conversion premium, and both move daily with metal markets. Quotes are usually valid for 1 to 3 days only.
Q: What is the typical thickness range for jumbo foil?
Jumbo rolls range from 0.0055 mm to 0.2 mm. Household foil stock is 0.011 to 0.016 mm; container and lidding stock is 0.02 to 0.09 mm.
Q: Why is 8011 jumbo foil cheaper than other grades?
8011 uses standard feedstock, rolls at high speed and has low scrap loss, so its conversion cost is lowest. Specialty grades like 8079, 8021-O and 3003 or 3004 cost more per ton.
Q: Is the quoted price the final price?
Usually the price is fixed on the deposit date using that day's LME or SHFE price, plus a fixed conversion premium. Confirm the base date, the price basis and the payment terms in writing.
Q: How long does a jumbo foil quotation remain valid?
Typically 24 to 72 hours. A firm quotation for delivery in 30 to 60 days can be locked with a deposit; otherwise the price floats with the metal market.
