What are SupremeCorqs made of?

A SupremeCorq closure is made of a high-grade thermoplastic elastomer. Because it is made from an elastomer, the product has "elastic" type properties which allow it to expand, contract and rebound. SupremeCorq closures comply with FDA and EU regulations. This type of raw material is currently used in medical and baby products.

Synthetic closures are also made from natural materials. To produce food contact grade quality plastic, a variety of basic compounds such as carbon, hydrogen, oxygen and nitrogen are extracted from natural materials such as petroleum, coal and natural gas. These materials are combined together in a variety of sophisticated ways to produce different types of recyclable plastics.

Why should I select an injection molded closure over an extruded closure?

SupremeCorqs are injection molded because this method of production offers several benefits over extrusion:

•	Each unit is individually manufactured to ensure consistency
•	The outer skin completely seals the closure, protecting the internal cell structure and preventing wine absorption
•	The skin allows the closure to conform more readily to the bottle bore, insuring a proper seal
•	The complete outer skin makes the closure appear more attractive, natural, and finished in the bottle
•	Frayed edges and loose particle ends are eliminated
•	The potential for future product development/improvement is greater
•	Shorter, cost effective production runs are possible

Why are SupremeCorqs chamfered at the ends?

SupremeCorq closures are chamfered (slightly rounded) at the ends. This allows for easier initial insertion and extraction of the closure. The chamfered ends also allow for easier reinsertion for the customer after opening. It also ensures that the closure does not fray at the ends.
