I use Duck brand smooth top non-adhesive liner. It stays put and cushions as well as lines. It doesn't tear and can be washed, so lasts a very long time. Costs a bit more than paper, but if you factor in how long it lasts, it actually costs less. Duck brand liner

Ikea sells a nice thick clear liner. Be sure and know the size of what you need before you go shopping.

I use Life Liner from BB&B, as I like that it's ribbed, can be hosed/wiped down easily, and is non-adhesive. I have lined everything: drawers, cabinets, and the sectioned tray/cookie sheet cabinet over my ovens. Life Liner

Others swear by Cushy Cupboards: Cushy Cupboard Liners

That one has mildew and mold protection which is important since we had the flood I know there's none in the house now and I want to avoid any problems from moisture.

I also use plastomat

Never used anything with new, never had any scratches or discoloration.

New cabinets generally don't need any liner except

Any drawers/cupboards where the contents may be put away damp

The contents are scratchy like a box grater

The contents are sticky/oily like oils or molasses or teriyaki sauce

We used the IKEA liner and the liner from Costco; very similar stuff. Nonadhesive.

Another another vote for the IKEA liner. Love it!

I had drawers that stored my big pots in a previous house . They had been used with out a good protective liner and they were very badly scratched from the movement of the pots and pans across the bottom so over time it definitely takes a toll . To try to lessen that I will be using a good heavy protective liner .

I like Life Liner best also.

I have both cushy cupboards and the Ikea liners. Both work fine.

Life Liner for dishes, glasses, pots & pans etc; cork for anything that small that will clank and make a racquet.

The only drawers that I line are the ones that I keep my oils in, or the one under the sink. I have the opaque ridged liner from Costco.

Another vote for Life Liner at BB&B. The ribs work great.

Is there such a think as a rubber/plastic liner for under the kitchen sink? I had the garbage disposal leak on the last cabinets and I didn't catch it for some time.

Yes there sure is saw some just the other day at Lowe's. I am sure Google will find a good selection.

@runs_with_scissors6 Yes, there is a great one for under the kitchen sink. It is made of silicone and mine held 2 gallons of water when my faucet disconnected under the sink during a party I had with caterers in the kitchen. It was a lifesaver during an inconvenient time. They vary depending on the measurements of the floor of the base cabinet under your sink. Here’s the link to mine:
