Food plastic jar

When sourcing food plastic jars, the material choice is paramount. PET (Polyethylene Terephthalate) is the industry standard for its high clarity, impact resistance, and excellent moisture barrier properties, making it ideal for dry goods and cold-fill liquids. For products requiring hot-filling or microwave use, PP (Polypropylene) is preferred due to its higher heat resistance (up to 120°C). Always ensure the material is 100% Virgin Food Grade and free from recycled contaminants to prevent chemical leaching.

To ensure legal entry into global markets, buyers must verify that suppliers hold FDA (U.S. Food and Drug Administration) or EU Framework Regulation (EC) No 1935/2004 certifications. Additionally, look for BPA-Free declarations and ISO 22000 (Food Safety Management) or HACCP certifications at the manufacturing site. For the European market, compliance with REACH and RoHS regarding heavy metals in colorants is also mandatory.

The integrity of the seal determines the product's shelf life. You should request information on the liner type, such as Induction Heat Seals (IHS) for tamper evidence and airtightness, or Pressure Sensitive (PS) liners for ease of use. Evaluate the neck finish (e.g., 400-series threads) to ensure compatibility with closures. For high-moisture or oxygen-sensitive foods, ask for Oxygen Transmission Rate (OTR) and Water Vapor Transmission Rate (WVTR) test reports.

Professional suppliers on Made-in-China.com typically offer OEM/ODM services including custom mold development for unique shapes, color masterbatch matching (Pantone), and various decoration techniques like silk-screen printing, heat transfer labeling, or UV coating. For branding, embossing or debossing logos directly onto the jar or lid is a common high-end customization strategy.

Plastic jars are lightweight but voluminous and susceptible to crushing. Require the supplier to use 5-layer corrugated export cartons and palletize the shipment with plastic wrap and corner protectors. For thin-walled jars, specify internal dividers to prevent friction scratches. It is highly recommended to hire a third-party inspection service to conduct a Drop Test (ISTA 1A) before the final balance payment is made.

Start by requesting a tiered pricing structure (e.g., 5k, 20k, 50k units) to understand the manufacturer's economies of scale. If your initial volume is low, negotiate a higher unit price in exchange for a lower MOQ, or ask to use existing public molds to waive the Tooling/Mold Fee (which can range from $2,000 to $5,000). Always clarify if the quoted price is FOB (Free On Board) to avoid unexpected local logistics charges.

Utilize the Secured Trading services provided by Made-in-China.com to protect your payment until shipping documents are verified. To ensure quality consistency, request a Pre-Production Sample (PPS) for signed approval. During mass production, insist on an AQL 2.5/4.0 inspection standard. Ensure the Proforma Invoice (PI) explicitly states the material grade, weight (in grams), and tolerance levels to provide legal recourse in case of disputes.

Due to the high 'volumetric weight' of plastic jars, Sea Freight (FCL - Full Container Load) is the most economical method. If you cannot fill a 20GP container, LCL (Less than Container Load) is an option, but be aware of higher handling risks. For urgent samples, International Express (DHL/FedEx) is best, but for bulk, always calculate the CBM (Cubic Meters) carefully, as shipping air can often cost more than the product itself.
