About Gunkapak - Packaging Items & Containers Supplier in Turkey

Turkey hosts Gunkapak with an active catalogue of seven distinct closure products. The supplier lists twist‑off caps in diameters of 38 mm, 43 mm (color printed), 53 mm, 63 mm, 66 mm and 82 mm, as well as metal jar lids sized at 82 mm. All items fall under the broader categories of Packaging Items & Containers and Glass Bottles, Jugs, Jars & Sealings, matching the supplier’s declared top categories. Each product is presented without additional accessories, focusing on the closure itself and its standard size designation.

The catalogue concentrates on caps designed for glass containers, with the twist‑off mechanism covering a range of common bottle neck diameters. The inclusion of a color‑printed 43 mm cap indicates a capability for branding, while the metal 82 mm jar lid suggests service for larger jar applications. No HS codes are attached to the listings, so classification must follow the generic HS chapters for plastic closures (chapter 39) and metal closures (chapter 73).

Product Range and Specialties of Gunkapak

Gunkapak’s product set comprises standard twist‑off caps typically manufactured from polypropylene or high‑density polyethylene, materials favored for their chemical resistance and food‑contact suitability. Common industry grades for these caps include FDA‑compliant and EU‑regulated food‑contact plastics, with specifications such as a minimum melt flow index of 12 g/10 min and a moisture absorption below 0.2 %. The 82 mm metal jar lid is usually supplied in aluminum or tin‑plated steel, featuring an internal sealing liner to provide a moisture‑tight closure for wide‑mouth jars. Buyers often request additional options such as tamper‑evident bands, embossing, or custom color printing, which align with the listed color‑printed 43 mm cap.

Trade and Export Information - Gunkapak

Turkey ranks among the leading exporters of plastic and metal closures in the Eastern Mediterranean, with primary shipment corridors to the European Union, the Middle East and North Africa, and the United States. Caps of the sizes listed are classified under HS chapter 39 for plastics and chapter 73 for metal, and are routinely inspected under the EU’s REACH framework and the United States’ FDA food‑contact regulations. Export packaging commonly involves bulk cartons or shrink‑wrapped pallets, allowing a 20‑foot container to hold roughly 20 000 to 25 000 individual caps depending on size, while metal lids are packed in reinforced boxes to prevent deformation. Standard Incoterms such as FOB Istanbul or CIF Mediterranean ports are typical for Turkish closure exporters.

Sourcing from Gunkapak - Buyer Guidance

When sourcing from Gunkapak, request a material data sheet that confirms the polymer grade, melt flow index and compliance with FDA or EU food‑contact standards. Verify the thread dimensions (e.g., 28‑410 or 38‑400) against the bottle neck specifications, and ask for a sealing test report that documents torque‑off values and leak‑proof performance. Typical minimum order quantities range from 5 000 to 10 000 units per size, with lead times of four to six weeks after sample approval; confirm packaging details such as carton count, pallet configuration and any required moisture barrier liners before finalizing the order.

What material are the twist‑off caps made from?

The caps are generally produced from polypropylene (PP) or high‑density polyethylene (HDPE), both of which meet common food‑contact regulations.

Which thread standards apply to the listed cap sizes?

Standard bottle‑neck threads such as 28‑410 (for 38‑66 mm caps) and 38‑400 (for 82 mm caps) are commonly used; the supplier should confirm the exact thread profile for each size.

Are the caps compliant with food‑safety regulations?

Buyers should request certificates of compliance for FDA food‑contact or EU Regulation 1935/2004; these documents confirm that the material meets required safety standards.

What is the typical packaging format for bulk orders?

Caps are usually packed in bulk cartons or shrink‑wrapped pallets, with a 20‑foot container accommodating approximately 20 000‑25 000 caps depending on the size.

What are the common incoterms used for shipping from Turkey?

Exporters from Turkey frequently use FOB Istanbul or CIF Mediterranean ports, allowing buyers to arrange inland transport from the designated port.

Is a sample available before placing a large order?

Suppliers normally provide a pre‑production sample for dimensional and sealing verification; the sample cost is usually reimbursed against the first purchase order.

What documentation is required for customs clearance?

Customs typically require a commercial invoice, packing list, certificate of origin, and any applicable food‑contact compliance certificates for the closures.

What are the usual lead times for the caps and metal lids?

Lead times are generally four to six weeks after sample approval, with metal lids potentially requiring an additional week due to stamping processes.
