Plastic can

When sourcing plastic cans for food or beverage use, the primary material choice is PET (Polyethylene Terephthalate) due to its high transparency and excellent moisture barrier properties. It is essential to ensure the material is BPA-free and complies with FDA (U.S.) or EFSA (EU) food contact regulations. For hot-fill applications, you must specify Heat-Resistant PET, as standard PET may deform at temperatures above 60°C.

Sealing performance depends on the combination of the can body and the lid type. For long-term storage, Easy-Open Ends (EOE) made of aluminum or tinplate provide the best hermetic seal but require a seaming machine. For reusable options, screw caps with PE liners or induction foil seals are recommended. You should request vacuum leak tests and drop tests from the supplier to verify that the cans maintain their seal during pressurized transport.

To prevent jamming in automated lines, ensure a dimensional tolerance of ±0.5mm. The neck finish (e.g., 38mm, 55mm) must be standardized to fit your filling nozzles and capping heads. Additionally, specify the gram weight of the preform; a higher gram weight results in thicker walls, which increases top-load strength and prevents the cans from collapsing under the weight of stacked pallets.

Global markets are increasingly demanding sustainable options. Look for suppliers who can provide rPET (recycled PET) content, typically ranging from 25% to 100%. Ensure the products are marked with the Resin Identification Code (RIC) #1 for easy recycling. Compliance with the EU Single-Use Plastics Directive or local Extended Producer Responsibility (EPR) schemes is vital for legal market entry in many regions.

Plastic cans are lightweight but high-volume (high 'dim weight'). The main risk is thermal deformation in shipping containers crossing the equator. You should request heavy-duty 5-layer corrugated outer cartons and consider sea freight with temperature monitoring. For large orders, shipping preforms instead of finished cans can significantly reduce shipping costs, though this requires a blow-molding machine at the destination.

Start by verifying the supplier's Audited Supplier status on Made-in-China.com to ensure they have undergone third-party onsite inspections. Negotiate based on Total Cost of Ownership (TCO) rather than just the unit price. Ask for tiered pricing (e.g., 10k, 50k, 100k units) and request that mold costs be amortized or refunded once a certain order volume is reached.

Always use Secured Trading Services offered by the platform to protect your payments until the goods are shipped. Before the final payment, hire a third-party agency (like SGS or Intertek) to conduct a Pre-Shipment Inspection (PSI). Focus the inspection on wall thickness consistency, clarity (haze levels), and brimful capacity accuracy.

Check the HS Code (typically 3923.30) for specific import duties in your country. Be aware of Anti-Dumping Duties that some regions apply to plastic products from specific origins. Ensure the supplier provides a Certificate of Origin (CO) to benefit from potential Free Trade Agreements (FTA) which can reduce or exempt import tariffs.
