GPI 38 Plastic Screw Cap (Bottle Closure)

The GPI 38 Plastic Screw Cap is a black, ribbed polypropylene closure with an EPE sealing insert, designed for secure closure of bottles with a GPI 38 mm neck.

• GPI 38 screw cap for GPI 38mm neck
• Black ribbed PP design for secure grip
• EPE sealing insert for leak protection
• Compatible with PET containers and bottlers
• Packed in practical 50-piece units

Durable material for repeated use and handling

The cap is molded from PP (polypropylene) for consistent dimensions and mechanical stability. PP resists common chemicals used in bottling and keeps threads precise over long production runs. The ribbed surface improves manual handling and automated feeding reliability.

Reliable seal performance under fill-line stresses

An EPE sealing insert provides a resilient, compressible barrier that compensates for minor neck tolerances. This reduces leakage risk during transport and storage. Sealing performance maintains headspace integrity and supports carbonation or non-carbonated fills.

Designed for straightforward integration in lines

Thread form and outer geometry match the standard GPI 38mm neck interface. Caps feed cleanly in capping machines and stack reliably in hoppers. Consistent neck fit minimizes downtime from rejected threads or misfeeds.

Supply options for commercial fillers and logistics

Packaging is arranged in practical 50-piece units for easy handling. VPE tiers are aligned with commercial fillers, and larger quantities can be supplied on palletized batches to simplify warehousing and line replenishment.

Targeted at bottlers and industrial packers

This closure suits PET bottlers and beverage fill lines that require repeatable closures and predictable torque. The GPI 38 Plastic Screw Cap supports high-throughput environments where thread accuracy and seal consistency impact OEE.

Technical documentation and traceability

Technical data and the secure product file are available for inspection to verify dimensions and material details. Recycling code 05: PP is applied to the material specification for downstream sorting and processing.

Kernfeatures

Sturdy PP construction

Made from PP, the cap offers dimensional stability and chemical resistance. The material selection supports mass production and reduces deformation under capping torque.

EPE sealing insert

The integrated EPE insert adapts to minor neck variations and preserves seal integrity. This feature reduces rework and lowers the incidence of leaks during distribution.

GPI 38mm compatibility and handling

Thread geometry matches the GPI 38mm neck standard. The ribbed exterior enhances grip during manual application and improves orientation in automated feeders.
