GPI screw cap for sealing PET containers from our product range.

The screw cap is equipped with an induction seal. After screwing on the cap, the IHS (Induction Heat Seal) insert is bonded to the container using an induction sealing device. Reliable seal with the rim of the container. Easy to remove when reopening the container. Tamper-evident.

GPI 38 Plastic Screw Cap, Black Ribbed, IHS

The GPI 38 Plastic Screw Cap is a polypropylene screw closure for GPI 38mm necks, designed to provide induction-sealed tamper evidence and reliable performance in liquid filling and packaging applications.

• Screw cap for GPI 38 mm necks
• Made from polypropylene (PP)
• Induction liner for tamper evidence
• Ribbed exterior for secure grip
• Recycling code C/PP for sorting

Consistent closure and production compatibility

The GPI 38 Plastic Screw Cap delivers uniform closure performance for containers with a GPI 38mm finish. Constructed from polypropylene, the cap retains its form under typical production stresses. The design supports both automated capping lines and manual application, ensuring steady throughput and fewer rejects during filling.

Sealing performance that reduces rework

The integrated induction liner forms a heat-activated bond that creates a reliable barrier against leaks and contamination. This sealing method minimizes rework and downtime. As a result, line efficiency improves and quality checks show fewer seal-related issues in standard production runs.

Ergonomic grip for faster handling

The ribbed exterior improves manual handling and torque application on packing lines. Operators obtain a secure grip, reducing slippage during capping and speeding up manual processes. The profile also eases automated tumbling and orientation in high-speed feeders.

Material traceability and sorting benefits

Made of PP with recycling code C/PP, the cap is classified for standard material sorting. The clear coding supports downstream waste handling and facilitates communication with packaging and recycling partners. Material choice also contributes to consistent molding and dimensional stability.

Packaging options for commercial fillers

Packaging units are matched to commercial filler needs and VPE staffels are available for industrial customers. Larger quantities can be supplied on palletized shipments to simplify storage and logistics. This approach supports contract packers and bottlers with predictable replenishment.

For reliable, induction-sealed performance on production lines, specify the induction-sealed GPI 38 screw cap for consistent sealing and handling.

Kernfeatures

Durable polypropylene construction

The cap is molded from polypropylene, offering dimensional stability and resistance to common liquid formulations. This yields consistent fit and reduced deformation during transport and storage.

Induction liner for hermetic seals

The built-in induction liner enables heat-activated bonding to the container rim. The result is immediate tamper evidence and reduced leakage risk after sealing.

Ribbed external design

A ribbed surface improves manual torque control and machine handling. The profile reduces slippage and speeds up both manual and semi-automated capping operations.

Logistics-friendly packaging

Supply units are tailored to industrial workflows and palletized shipments are available for larger orders. This supports efficient warehouse handling and streamlined restocking.
