Aluminum-plastic Screw Closure GPI 28 Flat, Copper — Screw closure for spirits bottles

The Aluminum-plastic Screw Closure GPI 28 Flat, Copper is a hand-twist screw closure for spirits bottles with a GPI 28 continuous-thread mouth, offering a low-profile Flat-Line look and decorative metallic appearance.

  • Screw closure for GPI 28 bottle mouths
  • Flat-Line low-profile design
  • Decorative copper aluminum outer shell
  • Hand-twist application, quick and simple
  • Food-contact conformity documents available

Precision fit for GPI 28 mouths

The Aluminum-plastic Screw Closure GPI 28 Flat, Copper is engineered for GPI 28 continuous-thread necks. It seals via the plastic core engaging the bottle land and supports glass or PET bottles. Recommended target torque ranges around 12–21 in-lb (≈1.4–2.4 Nm) for a reliable seal.

Flat-Line design improves presentation

The low-profile Flat-Line geometry reduces shoulder height and creates a flush cap silhouette. The copper aluminum outer shell provides a warm, handcrafted look that improves shelf impact and supports premium positioning without adding bulk to the bottle.

Durable aluminum-plastic construction

A polypropylene-like plastic core with an aluminum outer wrap combines reliable sealing performance and metallic haptics. Typical mass is ≈3.8 g per piece, with a full retail pack weight around 0.19 kg for a VPE of 50, keeping transport and storage compact.

Fast hand application for small batches

Designed for manual closure, each cap applies in seconds. Adding a shrink sleeve for tamper-evident appearance takes an extra 2–5 seconds per unit depending on the process. No roll-on or ROPP equipment is required for hand or semi-automatic filling.

Economic option for craft and small-scale fillers

Low unit cost and no need for specialized roll-seaming machines reduce upfront investment. Packaging units and tiered pricing are aligned with commercial fillers, and larger pallet quantities are available for scale-ups without changing the filling workflow.

Designed for craft distillers and fillers

Target users are craft distilleries, small bottlers, farm shops, and contract fillers seeking a premium look with simple application. The cap supports non-carbonated, ethanol-based spirits and complements gift and sample bottlings.

Consider Etivera’s aluminum-plastic screw closure to enhance product appearance while keeping hand-filling efficient and scalable

Kernfeatures

GPI 28 compatibility and fit

The cap matches GPI 28 continuous-thread necks used across common spirit bottle lines. Compatibility is ensured by the plastic core geometry and CT standard threading, facilitating interchangeability with standard GPI 28 bottles.

Flat-Line copper finish and shelf impact

The copper-colored aluminum wrap creates a premium metal look and a warm tactile impression. The flat, low profile preserves label visibility and contributes to a refined unboxing experience.

Hand-fit application and process guidance

Hand-twist closure requires no specialized machinery. Keep the bottle neck clean and apply evenly to reach target torque. For TE appearance, pair with a Ø34 × H27 mm shrink sleeve and a brief heat-shrinking step.

Compliance documentation and materials

Food-contact conformity documents and producer part number (GPI-F28CU#P50Z) are available. The aluminum outer shell and plastic core combination is specified for non-carbonated spirit applications.

    Mit Einschränkung zu empfehlen
    Manche rutschen beim Draufschrauben durch, dadurch kann der Verschluss nicht ganz festgezogen werden. Betrifft Ca. jeden 10ten einer Packung. Egal ob bronze oder silber.
