Create long-lasting, low-maintenance container displays with our durable planter liners. These plastic planter inserts offer lightweight performance, versatile sizing, and reliable strength. Explore the Planters Unlimited collection to find the right fit for your project.
A small investment that delivers long-term results, plastic for lining planters helps prevent damage, reduce replacement costs, and keep beautiful planters looking sharp year after year.
The liners in Planters Unlimited’s fiberglass and PVC collection more than deliver on that promise, thanks to their construction from commercial-grade materials. More durable than standard plastic planter inserts, our liners ensure:
• No corrosion
• No mold
• No rot
Planters made of materials that can be susceptible to damage – such as stone, metal, and wood – are fully protected, helping them look new even years after purchase. And with no risk of warping, cracking, or bowing, our plastic planter inserts are built to last.
Whether you purchased your existing containers elsewhere or you’re including new commercial planters in your Planters Unlimited order, we offer plastic planter inserts that fit nearly every type of planting vessel.
• Rectangular and Square: Rectangular lengths reach up to 71”, and squares measure as large as 47” per side.
• Round: Diameter and height ranges extend from 17” to 47”.
• Tapered: Rectangular, square, or round sizes with narrower bottoms to fit comfortably into tapered planters.
• Hanging Basket: From 18” to 42” in diameter, with built-in side straps for easy positioning.
• Window Planter Box: Ideal for lining window boxes in lengths from 24” to 72”, these PVC liners can also be mounted as stand-alone containers.
In addition to lining planters, all of our plastic inserts can also be placed directly in the ground to protect plant roots, control drainage, and reduce erosion.
Choosing the right plastic planter inserts begins with correct sizing. Carefully measure each of your planters’:
• Widths
• Depths
• Tapers
Be sure to take your measurements from the inside of your planter, not the outside. Note that if you have an oversized or oddly shaped planter, you can combine multiple plastic planter inserts to fill out the space.
Plastic for lining planters should fit snugly to achieve peak performance. You’ll find that many of the plastic planter inserts offered by Planters Unlimited are engineered to be just slightly smaller than our most popular planters. If, for instance, you’re ordering a Modern Corten steel planter that measures 36” square, you should order a fiberglass liner measuring 35” on all sides.
From plastic planter inserts that protect your greenery to site amenities that perfectly coordinate with your large-scale planters, we are your full-service resource for any commercial landscaping project. Every item we build is designed to maximize durability, functionality, and beauty.
Designers and facility managers turn to Planters Unlimited when they want exceptional value, short lead times, and impeccable craftsmanship. Virtually everything we offer is customizable – if you don’t see what you’re after online, contact us for a quote.
