Which aluminium alloys do you use for cans, ends and coil?

Can bodies are drawn from 3104-H19 aluminium, easy-open ends from 5182-H48 shell stock and tabs from 5052, while lacquered coil for lids is supplied in 8011 and 3104 tempers. Every coil arrives with a mill certificate stating alloy, temper, thickness tolerance and surface class.

What is the minimum order quantity for aluminium cans and easy-open ends?

Standard bright or plain cans start at one 20 ft container; fully printed cans normally start at 100,000 pieces per design because of plate and lacquer set-up. Easy-open ends in 200#, 202#, 206#, 209#, 211#, 300#, 307#, 401# and 502# are stocked, so trial orders from 200,000 pieces can ship within 15 working days.

Are your lids and cans food-contact compliant for export markets?

Internal lacquers are BPA-NI and are tested against FDA 21 CFR 175.300, EU Regulation 1935/2004 and GB 4806.10 for food-contact migration. We supply migration test reports, food-grade declarations and RoHS/REACH statements with each shipment.

How do you protect aluminium packaging during ocean freight?

Cans travel on bulk pallets with top frames, kraft slip sheets and stretch hood film; ends are packed in polyethylene sleeves inside fibre drums or cartons with desiccant. Loading photos and container seal numbers are sent before vessel departure so quality can be verified on arrival.

Can you match a filling line with specific can and end dimensions?

Yes. Share your seamer model, line speed and target fill volume and our engineers will confirm can height, body wall gauge, neck diameter, end curl and countersink depth, then supply drawings and a sample lot for seam teardown analysis before mass production.

Mumbai Commercial & Industrial Packaging Ecosystem: Engineering for Extreme Humidity

The Greater Mumbai Metropolitan Region (MMR)—stretching from the port industrial clusters of Navi Mumbai and Jawaharlal Nehru Port Trust (JNPT) to the heavy chemical and pharmaceutical belts of Tarapur MIDC, Thane-Belapur, Taloja, and Patalganga—represents India’s most demanding industrial packaging landscape. As the commercial powerhouse of India, Mumbai manufactures, processes, and exports billions of dollars worth of bulk active pharmaceutical ingredients (APIs), specialized nutraceutical powders, infant formulas, fine chemicals, and agrochemical formulations annually.

However, Mumbai’s coastal tropical monsoon climate poses an extreme challenge to powder shelf-life stability. With ambient relative humidity levels exceeding 85% for more than five months of the year, standard packaging closures frequently suffer from micro-cavitations, oxidative degradation, and moisture ingress. Moisture contamination in powdered pharmaceuticals or hygroscopic food powders triggers rapid caking, loss of bio-availability, enzymatic breakdown, and severe package swelling.

Coastal Atmospheric Moisture Isolation

Industrial packaging engineers in Mumbai require Hermetic Barrier Engineering. Our specialized powder lid products utilize 5182-H48 temper aluminum shell stock combined with multi-layer organosol and acrylic-polyester internal lacquers. This provides an absolute zero-permeability shield against water vapor transmission (MVTR < 0.001 g/m²/day), guaranteeing that sensitive milk powders, proteins, and chemical reagents remain free-flowing even during peak Mumbai monsoons.

Non-Magnetic & Anti-Static Compliance

In the pharmaceutical corridors of Navi Mumbai and Thane, active ingredients must undergo cleanroom filling without triboelectric charge build-up. Our Anti-Static & Non-Magnetic 209FA# and 300# Powder Lids eliminate static attraction between fine powders and the lid perimeter during high-speed vacuum dosing, ensuring clean double-seam integrity and zero powder entrapment in the curl zone.

Expert FAQ

Technical & Sourcing Questions Answered by Packaging Engineers

In-depth answers addressing logistics, metallurgy, atmospheric protection, and filling line performance for Indian market buyers.

Q1: How do your powder lids prevent oxidation and moisture clumping during Mumbai's monsoon season?

Our powder lids utilize high-purity AA 5182 aluminum alloy combined with continuous water-based rubber perimeter gaskets. Unlike traditional tinplate lids that can develop pinhole rust under high humidity, aluminum is inherently rust-proof. Combined with a multi-layer impermeable organosol barrier coating, moisture vapor transmission rates (MVTR) are kept below 0.001 g/m²/day, ensuring sensitive infant formulas and APIs remain completely dry and free-flowing.

Q2: What is the typical transit shipping time from your Shanghai facility to JNPT Port in Mumbai?

Direct container shipping from Shanghai Port to Nhava Sheva (JNPT) port in Mumbai takes between 14 and 18 days on direct maritime services. We manage export documentation, including packing lists, commercial invoices, Mill Test Certificates (MTC), and food-contact certificates, allowing your customs broker in Mumbai to clear shipments efficiently under Indian BIS and customs regulations.

Q3: Are these aluminum easy-open ends compatible with existing filling line seamers in India?

Yes. Our ends are manufactured to standard international industry diameter codes (206#, 209#, 300#, 305#, 307#, 401#, and 502#). They seamlessly integrate with standard automatic automatic filling and seaming equipment including Angelus, Ferrum, Somme, and Asian high-speed seamers. We provide complete seam teardown specifications and initial sample lots for trial seaming before mass volume production.

Q4: Why is an anti-static coating necessary for electronic-grade and pharmaceutical powders?

Ultra-fine powders (such as micronized active pharmaceutical ingredients or specialized electronic ceramic powders) build up static charges during high-speed vacuum dosing. Static attracts fine particles to the lid flange and curl area, which can compromise the secondary seal or cause powder puffing upon opening. Our Anti-Static 300# Lid features a specialized conductive lacquer that dissipates electrostatic charges, ensuring clean filling and zero product wastage.

Q5: Can you customize the score opening force for consumer-friendly opening?

Absolutely. Score residual thickness is precisely controlled to within ±0.002 mm using optical sensor profilers. This ensures an optimal balance: high buckle resistance against internal gas pressure or nitrogen flushing during packing, combined with low consumer pop-and-pull forces (< 30N pop force) for effortless opening without smooth-edge injury risk.

Q6: What minimum order quantity (MOQ) applies to trial orders bound for Mumbai?

For standard stocked sizes (such as 206#, 300#, and 401# ends in plain gold or clear lacquer), trial orders start at 100,000 to 200,000 pieces (roughly one LCL or combined FCL pallet shipment). Custom litho-printed tabs or specialized transparent window lids carry MOQs based on coil coating run lengths. Contact our engineering team for customized batch calculations.
