Wholesale Recycled Plastic Mason Jar Factories & Factory

Our factory sources certified post-consumer recycled (PCR) resin pellets that have undergone rigorous decontamination and solid-state polycondensation (SSP). These materials carry Letters of No Objection (LNO) issued by the US FDA and formal European Food Safety Authority (EFSA) scientific opinions. Every master production batch is tested by accredited third-party laboratories (such as SGS or TÜV) for non-intentionally added substances (NIAS), overall migration limits (OML), and specific heavy metal migration compliance.

For private-label orders utilizing our existing, factory-owned molds with custom PMS colors, electroplating, gradient finishes, or brand logo printing, our standard MOQ starts at 1,000 to 3,000 units per colorway. For fully bespoke shapes requiring dedicated tooling, injection molds, and blow cavity fabrication, the MOQ is typically 10,000 to 20,000 units. Mold costs are amortized and can be credited back upon reaching designated contractual volume tiers.

While lower-grade recycled plastics exhibit haze and a yellowish-green tint, our use of optical-grade rPET coupled with vacuum thermal desorption preserves optical transmission close to that of virgin resin (haze < 2.5%). Our engineering team compensates for minor polymer base variations by adjusting thermal profiles during the stretch blow molding cycle and dosing precise blue-violet toner matrices. Structural rigidity and intrinsic viscosity (IV) are maintained at ≥ 0.80 dL/g to ensure drop-impact toughness identical to virgin polymers.

Standard food-grade rPET mason jars have a heat deflection temperature threshold of 65°C to 70°C and are designed for cold-brew coffee, smoothies, and room-temperature beverages. If your project mandates boiling water resistance and commercial high-heat dishwasher resilience, we produce jars using Tritan™ Renew (molecularly recycled copolyester) or engineered recycled polypropylene (rPP), which comfortably withstand continuous temperatures up to 98°C–100°C without dimensional deformation or chemical leaching.

We operate an extensive in-house decoration workshop including vacuum electroplating (mirror metallic finishes), automated gradient and matte UV spraying, automated silk-screen printing, rotary multi-color heat transfer, water-transfer decals, laser etching on metal lids, and hand-applied rhinestone drill sticker wraps. We perform cross-hatch adhesion testing and solvent rub tests on all coatings to ensure long-term durability.

Pre-production rapid 3D prototypes can be delivered in 3 to 5 business days. Pilot mold creation and functional sample dispatch take approximately 10 to 14 days. Once pre-production samples are approved in writing and deposit terms are met, standard containerized mass production (20GP/40HQ) typically takes 25 to 35 days, subject to the complexity of the chosen surface decorations and packaging specifications.
