Plastic liners:

• cost less.
• will flex so that unloading a sample is easier.
• may be cut with a carpet knife to unload saturated clay samples.
• also may be cut to shorter lengths as desired.

Stainless steel liners:

• are far more durable than plastic. Can be reused many times.
• satisfy the most stringent sampling protocols.
• do not flex. Unloading some saturated samples may be very difficult.
      (We recommend using the shortest liner you can.)
• can not be cut to shorter lengths in the field.
