Key Features of Our Square HDPE Plastic Buckets with Lid
100% Virgin HDPE Construction
Injection-molded from 100% virgin HDPE - no recycled content - with reinforced corner ribs that hold up against acids, alkalis, and rough handling without cracking.
Rubber Gasket Lid Seal
A food-grade rubber gasket sits inside each lid, pressing firmly against the bucket rim to block out moisture, dust, and odors - keeping dry goods and paste materials uncontaminated through storage and transit.
FDA 21 CFR Compliant & BPA-Free
These HDPE plastic buckets contain no BPA and carry no odor, meeting FDA 21 CFR standards for direct food contact. Rated for use between -20°C and 60°C, they hold up in cold storage environments without warping.
Space-Saving Stackable Design
Flat-sided square pails sit flush on pallets, freeing up roughly 20% more shelf space than round buckets of the same volume. Empty buckets nest inside each other, cutting return shipping costs.
Tamper-Evident Lid
An optional tear-tab seal leaves clear visual evidence once broken - meeting traceability requirements for food, agrochemical, and pharmaceutical supply chains.
What Are HDPE Square Buckets Used For?
Food & Dry Goods
These square buckets for food packaging handle flour, sugar, starch, oats, powdered milk, and pet food.
Chemical Storage
Suitable for powdered or paste chemicals including detergents, industrial grease, coatings, and sealants. HDPE resists acids and alkalis without reacting with contents.
Agriculture
Works for fertilizers, seeds, powdered pesticides, and animal feed. The square profile makes full use of pallet space, ideal for high-volume warehouse storage.
Paints & Inks
A go-to plastic square bucket format in the paint, pigment, and ink industry. Four flat sides give more printable area for silk-screen or IML labels than round pails.
Construction
Handles dry-mix mortars, waterproofing powder, and adhesives. UV stabilizers in the material make it suitable for outdoor job sites.
Commercial Storage
Good for cleaning supplies, hardware, and garden materials. Multiple color options support zone-based organization in warehouses.
