Spray packaging

The choice of material depends heavily on the chemical compatibility of the contents. PET (Polyethylene Terephthalate) is ideal for cosmetics and personal care due to its high clarity and recyclability. HDPE (High-Density Polyethylene) is preferred for industrial cleaners and chemicals because of its superior chemical resistance and durability. For premium products or those sensitive to light, Amber Glass or Aluminum containers provide the best UV protection and barrier properties to prevent product degradation.

The 'output' or 'dosage' (measured in ml or cc) is critical. For water-like liquids, a Fine Mist Sprayer with a dosage of 0.1cc to 0.2cc is standard. For thicker liquids like lotions or gels, a Treatment Pump is required. If the product contains oils or harsh solvents, ensure the internal gaskets and O-rings are made of Viton or NBR (Nitrile Rubber) to prevent swelling and mechanical failure.

Ensure the supplier complies with ISO 9001 for quality management. For food or cosmetic contact, FDA or EC 1935/2004 certifications are mandatory. Crucial quality tests include the Vacuum Leak Test (to ensure no leakage during air transport), Dip Tube Length Accuracy, and Actuation Force Testing to guarantee the pump doesn't jam after repeated use.

Yes, professional suppliers on Made-in-China.com offer extensive customization. This includes Silk Screen Printing, Hot Stamping, and UV Coating for aesthetics. Functional customization includes Custom Dip Tube Lengths to fit specific bottle heights and Color Matching via Pantone codes for the pump actuators and overcaps.

The primary risk is leakage or breakage during transit. Always request double-wall corrugated export cartons and palletization. Another risk is component incompatibility; always perform a compatibility test by filling the sample bottles with your actual formula for at least 4 weeks to check for reactions like bottle collapsing or pump clogging.

Focus on the Defect Rate Agreement. A standard AQL (Acceptable Quality Level) for packaging is 1.0 for critical defects and 2.5 for major defects. Negotiate a spare parts ratio (usually 1-2% extra pumps) to be included in the shipment at no extra cost to cover potential functional failures.

Since empty bottles have high volume but low weight, you are often charged by Volumetric Weight. To optimize costs, consider nesting packaging or sourcing bottles and pumps from the same region to consolidate shipping. For international trade, clarify the Incoterms; FOB (Free On Board) is generally recommended for buyers who want control over their freight forwarder and shipping costs.

Utilize the Secured Trading Services provided by Made-in-China.com. Always verify if the supplier is an Audited Supplier, which indicates their business license and production capabilities have been verified by third-party institutions like SGS or Bureau Veritas. Never wire full payments upfront; use a 30% deposit and 70% balance against the Bill of Lading (B/L) structure.
