Three-Hole Plastic Seal Capsule

The three-hole plastic seal capsule guides sealing wire through a defined arrangement to help close sacks, bags and packaging in a controlled way. The standard product is injection-moulded from PP copolymer. Its compact, lightweight form supports handling during manual sealing operations.

Alongside supply of the current product, İdeal Plastik can evaluate new capsules and injection moulds using the sealing wire, packaging type, dimensions or an existing sample. Suitability depends on the complete closing system, not only on the capsule's external appearance.

Product and development options

Different external dimensions, hole diameters, wire-routing arrangements and colours can be assessed against project requirements. Custom packaging, sample-based development and a dedicated injection mould may also be included. The final approach depends on wire type and diameter, packaging construction, the closing method and order volume.

Features and application areas

The three-hole geometry supports controlled wire passage. Injection moulding supports repeatable production of the approved geometry. The capsule can be evaluated for agricultural sacks, industrial bags, raw-material packaging, storage and shipment operations, and other packaging closed with wire.

Opening-control and security requirements must be assessed for the capsule, wire and closing method together. Do not assume universal wire compatibility or guaranteed tamper evidence from the capsule alone. A packaging application involving food does not itself establish approval for direct food contact; any such requirement needs separate review with the relevant material documentation.

Choosing the right capsule

For a quotation, specify the sack or bag construction, wire type and diameter, capsule dimensions, hole arrangement and closing method. Include colour, packaging, storage and exposure conditions, and annual consumption. An automated application requires an additional equipment-compatibility review.

Confirm exact dimensions, hole diameters and tolerances on a technical drawing. Without a drawing, a physical sample and application information can support measurement and manufacturability review. Check wire passage and the complete closing operation on samples before ordering. Where reuse or outdoor exposure matters, specify those conditions rather than assuming the standard capsule is suitable.

From project to series production

For the current product, the supply plan is based on colour, packaging and quantity. If its geometry does not fit the application, the drawing or sample is reviewed and a new capsule can be developed around the wire and routing arrangement. Design approval is followed by mould manufacture, trial moulding and sample checks. Series production is planned after the required application checks are accepted.

A Turkish-manufactured alternative to an imported capsule can be assessed from its sample, material requirements and operating conditions. Where the customer has a suitable injection mould, machine and process compatibility are reviewed before trial or series moulding with PP copolymer or another approved project material. Development work must respect third-party intellectual property rights.
