Qorpak offers a variety ways to purchases caps
Things to consider
The first number refers to the cap diameter (in millimeters). The second number refers to the height and thread configuration of the closure or finish. Below is a selection of commonly used caps and finishes. Click here to see our guide to How to Select the Right Size Cap for Your Bottle.
Closure Material & Liners
Cap Materials
Thermoset and Phenolic (Bakelite) - These caps are known for providing the widest range of chemical compatibility and for being the most temperature tolerant of plastic closures. They also provide the most consistent adherence to close dimensional tolerances. Thermoset and Phenolic caps are suggested for pharmaceutical applications. Thermoset closures cannot be re-melted after they are formed. Common resins include urea, phenolic and melamine.
Polypropylene (Thermoplastic) - Polypropylene caps are known for good impact strength, cost effectiveness and pliability. They can be re-melted after they are formed.
Metal - Metal caps offer the widest range of temperature tolerances and are very resistant to fracture from impact. Metal caps are great for industrial and food applications. A metal closure is manufactured from either steel (coated with anti-corrosive coating of either chrome-plate or tinplate) or aluminum.
