- Large 100-count bundle ensures low cost per painting project.

The Uiploib 100-Pack Paint Sprayer Cup Liners are disposable protective bags designed for DIY enthusiasts, woodworkers, and painting contractors who want to avoid the tedious chore of scrubbing spray gun canisters. Sized at 7.8 by 11.8 inches, these transparent liners fit inside Wagner sprayers and a wide range of standard paint gun reservoirs.
In practical use, these liners significantly accelerate the painting workflow. Switching between primer and topcoats, or swapping distinct colors, becomes a fast task that requires only pulling out the used liner rather than conducting a full solvent flush of the cup. The durable polypropylene film effectively holds up against both standard latex and harsh oil-based paints without degrading or tearing under pressure.
Each liner is built from resilient plastic that prevents messy leaks inside the spray container. An added advantage of the pliable plastic construction is paint recovery; users can easily snip a corner or squeeze the bag to drain leftover paint directly back into storage cans with minimal waste.
One minor inconvenience is the flat rectangular cut of the bags. Because they are not pre-molded to the contours of a round cup, excess plastic can bunch at the rim, occasionally requiring careful placement to guarantee an airtight lid seal. Overall, these liners offer exceptional time savings and equipment protection, making them a practical addition to any painter's toolkit.
