Wholesale Shaker Cocktail RPET Cup Manufacturers & Factory

A standard cup is designed exclusively for atmospheric containment and passive drinking. A wholesale shaker cocktail cup is a dynamic hydraulic device engineered to withstand aggressive manual agitation without leaking or lid displacement. It requires reinforced hoop-strength wall profiles (minimum 1.2–1.8 mm thickness), a high-pitch sealing thread, an internal ice/pulp separation strainer, and a calibrated air-tight gasket capable of handling alcohol solubility and thermal shrinkage during chilling.

Yes. Premium bottle-grade RPET displays high chemical resistance against ethanol solutions up to 55% ABV, as well as organic citrus acids (citric and malic acids from limes, lemons, and grapefruits). Unlike polystyrene (PS), which clouds and micro-crazes upon alcohol contact, our optical RPET maintains crystal clarity without leaching polymers or phthalate plasticizers into the spirit.

For existing tooling models in standard transparent RPET with custom logo silk-screen printing, our starting MOQ is 1,000 to 3,000 units. For fully bespoke shapes requiring dedicated tooling molds or custom Pantone body color tints, the MOQ is 5,000 to 10,000 units. Digital 3D SLA physical prototypes are dispatched in 3–5 days, while production-grade samples with custom graphics ship within 7–12 days.

Wuyi Ronchine Industry & Trade Co., Ltd. is the integrated export manufacturing group representing our drinkware production plants in Tongqin Industrial Park, Wuyi County, Jinhua, Zhejiang. By consolidating molding, UV painting, electroplating, drill stickering, and cleanroom packaging under one roof, international buyers work directly with our engineering department, bypassing intermediary trading margins.

We provide an exhaustive finishing suite: 360-degree cylindrical UV silk-screen printing, multi-color heat transfer printing, in-mold labeling (IML), robotic automated gradient color spraying, metal-luster vacuum metallization/electroplating, and manual rhinestone (drill sticker) hand-setting. Custom Pantone color-matching is verified via spectrophotometer to match your brand style guide.

Standard RPET has a glass transition temperature (Tg) of approximately 65°C (149°F), making it best suited for cold to ambient beverage service and top-rack gentle washing. For venues requiring high-temperature 85°C industrial sanitizing dishwashers, our engineers offer heat-stabilized modified RPET formulations or our reusable Tritan™ / 304 stainless steel tumbler series.

The client retains 100% proprietary ownership of custom injection and blow molds developed under our OEM tooling agreements. Tooling contracts include strict non-disclosure and exclusivity covenants guaranteeing that your proprietary geometry will never be shared, repurposed, or cataloged for third-party procurement.

Every shipment of raw recycled resin is backed by an authentic Global Recycled Standard (GRS) Certificate and batch-coded supply manifests. We verify feedstock purity via Differential Scanning Calorimetry (DSC) and intrinsic viscosity testing to prevent virgin resin substitution, supplying clients with an audited Certificate of Analysis (CoA) per production lot.
