Heavy-duty for landscaping materials. Plain or custom printed up to 3 colors.
Rock bags are heavy-duty polyethylene bags engineered for the demanding requirements of landscaping supply yards, garden centers, nurseries, and building material distributors. Built from 3-4 mil LDPE, these bags withstand the weight, sharp edges, and abrasive surfaces of decorative rock, gravel, pebbles, river stone, bark, mulch, and soil products without puncturing or tearing during filling, handling, and retail display.
The landscaping materials market requires packaging that can handle extreme conditions. A 50-pound bag of river rock puts tremendous stress on seam integrity, and sharp-edged gravel can slice through thinner poly in seconds. Our rock bags are manufactured with reinforced heat seals and thick-gauge LDPE specifically to survive these conditions. The seal strength is calibrated for the weight capacity of each bag size, so you get reliable performance from the filling station through palletization, shipping, and retail handling.
Available in capacities from 10 lbs to 50 lbs, our rock bags come in plain and custom printed versions. Printed rock bags are essential for branded landscaping products sold at retail — your company name, rock type, weight, coverage area, installation instructions, and decorative product photos can all be printed directly on the bag. We offer up to 3-color printing on rock bags, which is the industry standard for landscaping product packaging.
Plain rock bags are the economical choice for landscape supply yards that sell bulk materials bagged on site. These yards typically fill and label bags themselves, so an unprinted heavy-duty bag is all they need. For companies distributing bagged landscaping products to retail garden centers, printed bags are the standard and serve as both packaging and point-of-sale marketing.
We supply landscaping companies, garden centers, rock yards, and building material distributors across Southern California and nationwide. Southern California is one of the largest markets for decorative landscaping rock in the country, and we understand the specific demands of this industry. From small local rock yards to large regional distributors shipping pallets of bagged product, Flexible Poly Industries has the rock bags you need.

Custom sizes, gauges, and print designs are available for products that do not fit our standard configurations. If you need a bag sized for a specific weight of a particular material, we can manufacture it. Rock density varies widely — pea gravel is much lighter per volume than river rock — so bag dimensions must match both the weight and volume of the specific product being bagged.
Contact us at (626) 250-2030 for pricing on stock or custom rock bags. We offer volume discounts for pallet quantities and can work with your design team on printed bag artwork.
Decorative rock, gravel, pebbles, river rock, and crushed stone bagged for retail sale or job site delivery. Heavy-gauge poly withstands sharp edges and the weight of dense stone materials. The most common sizes are 20 lb and 50 lb bags for residential landscaping projects.
Retail-ready bagged stone, mulch, bark, and decorative ground cover sold at nurseries, garden centers, and home improvement stores. Custom printed bags with product photos and coverage information help customers select the right material and calculate quantities for their project.
Sand, aggregate, construction gravel, and specialty building materials packaged for contractors and construction supply distributors. The 4 mil gauge handles the heaviest materials without blowouts, and the bags stack cleanly on pallets for warehouse storage and jobsite delivery.
Soil amendments, fertilizer, seed, and growing media bagged for retail or wholesale distribution. Rock bags work for any dense, granular material that requires a heavy-duty poly bag. Available in sizes appropriate for both consumer retail quantities and commercial bulk bags.
Same-day shipping on stock sizes from our LA warehouse. Rush production available.

We offer rock bags in 10 lb (~10" x 15"), 20 lb (~12" x 18"), 40 lb (~14" x 22"), and 50 lb (~16" x 24") capacities. These dimensions are based on average decorative rock density. Custom sizes are available for materials with different density or volume requirements.
Yes. Rock bags are available with up to 3-color custom printing. This typically includes your company name, logo, product type, weight, coverage area per bag, and installation or usage instructions. Printed rock bags serve as both packaging and point-of-sale marketing at retail garden centers. Contact us with your design for a printing quote.
Standard rock bags are 3 mil for loads up to 20 lbs and 4 mil for heavier loads (40-50 lbs). The thicker gauge prevents punctures from sharp rock edges and provides the strength needed to support the weight of dense materials like river rock, gravel, and crushed stone. We can manufacture heavier gauges for specialty applications.
Rock bag sizing depends on both the weight and the bulk density of your material. Pea gravel is lighter per cubic inch than river rock, so the same weight of pea gravel requires a larger bag. Tell us the material type and the target weight per bag, and we will recommend the right dimensions. We can also send sample bags for you to test with your product.
Yes. We are based in Pasadena, CA and supply landscaping companies, rock yards, and garden centers throughout the greater Los Angeles area and Southern California. Local customers benefit from fast delivery and the ability to pick up orders directly. We also ship nationwide via freight for pallet quantities.
Yes. Our rock bags are manufactured from 3-4 mil LDPE specifically engineered for the abrasive, sharp-edged conditions of landscaping materials. The thick gauge and reinforced seals withstand the stress of sharp rock edges during filling, handling, and stacking. For extremely sharp materials like lava rock or crushed glass, we recommend the 4 mil gauge regardless of weight.
Custom printed rock bags require a minimum order to cover the cost of flexographic plate production and press setup. The minimum varies by bag size and number of print colors. Contact us at (626) 250-2030 for specific minimums on your project. Plain (unprinted) rock bags are available in smaller quantities with low minimums.
We manufacture rock bags to your exact specifications. Any size, gauge, material, or print.
