For the Holder Material option, there are typically two types of LED holder on the market: Aluminum and Copper.

What is LED Holder
The LED holder, also known as LED Base, is the base where the LED dies(chips) sit. By encapsulating the tiny chips in to the LED holders, the LEDs can be widely used on various lighting fixtures.

Aluminium Base LED Package
Since Aluminum based LED is Cheap, the regular package for them are Anti-static bags. For factory package, we do 1000pcs/lot package. Since our cart start with 1pcs for all, we will pack them with smaller Anti-static bags for small quantity orders
Copper Base LED Package
For copper based LED, we regular pack them with anti-static tubes. It is also an industrial practice. One anti-static tube can hold up to 50pcs/tube. But in our practical order process, we normally put them in to small anti-static bags too to minimize the length of the package. In the case of you order dozens tubes or your total order package is large enough, we will use the tube packaging.
