15L Square Plastic Pail with Liner (Tamper-Evident Seal + Reinforced Handle) | Stone-Finish Paint, Coatings, Seeds, and Multipurpose Industrial Packaging

This 15L In-Mold Labeled Square Plastic Bucket is specially developed for a wide range of industries, including stone-effect paint, stone-imitation paint, thick-paste artistic lime coatings, crop seeds, fertilizers, agrochemicals, and fine chemicals. The bucket body uses high-end In-Mold Labeling (IML) high-definition full-coverage film molding technology, where the label is tightly fused with the square bucket body. It features rich, vivid colors and high-definition graphics, with excellent scratch and abrasion resistance, water and chemical corrosion resistance, no peeling edges, and no fading, perfectly showcasing the brand image and premium texture.

The bucket body is precision injection-molded using 100% brand-new, high-impact copolymer polypropylene (PP) virgin material. The classic large-capacity square structure improves storage and pallet loading space utilization by more than 20% compared to traditional round buckets. It is equipped with a precision tamper-evident sealing lid and an ergonomic, high-toughness handle. The tight sealing prevents leaks, moisture, and clumping, while the even load distribution makes it easy to carry when full. It widely meets the high standards of building coating brands, seed companies, and industrial manufacturing customers for pressure resistance, impact resistance, stable stacking, and long-distance logistics transportation, and supports full OEM/ODM customization services.

Core Product Advantages

• High-definition four-sided panoramic display with In-Mold Labeling (IML): The flat square sides combined with the IML process provide a wider and flatter visual display area. The label is fused with the plastic base material, offering moisture, water, and scratch resistance, and staying as new as ever.
• Compact square structure saves storage and shipping costs: The regular square appearance allows pallets to be stacked tightly without gaps, significantly improving container loading rates and logistics space utilization, thereby reducing overall transportation costs.
• 100% brand-new high-strength PP virgin material: Selected high-toughness, high-impact polypropylene granules make the bucket body thicker and reinforced, offering impact and drop resistance, freeze and heat resistance, and excellent resistance to acids, alkalis, and solvents.
• Precision tamper-evident sealing lid, tightly preserving freshness and preventing leaks: The tightly interlocking tamper-evident sealing ring design leaves a trace upon opening for anti-counterfeiting, and the bucket can be inverted without dripping, effectively blocking external moisture and dust from entering.
• Ergonomic handle and non-slip stacking design: The reinforced integrated hanging ear combined with a tough handle makes it easy to carry 15 kg when full without cutting into the hand; the non-slip recessed top supports stable multi-layer vertical stacking.

Applicable Industries and Packaging Fields

• Building coatings and exterior wall projects: Stone-effect paint, stone-imitation paint intermediate coats, thick-paste artistic lime, texture coatings, exterior wall latex paint, waterproof coatings, and interface mortar.
• Seed industry and agricultural chemicals: Crop seed packaging, vegetable seeds, water-soluble fertilizer granules, powdered additives, pesticide formulations, and soil conditioners.
• Fine chemicals and industrial bulk packaging: Adhesives, industrial powders, water-based resins, grease, paste materials, and special chemical additives.

Specifications and OEM/ODM Customization Instructions

Strict Quality Inspection and Factory Testing

Before leaving the factory, Fono packaging buckets strictly undergo multiple industrial-grade quality inspection standards to ensure durable load-bearing and reliable protection:

01 Brand-new Polypropylene (PP) Virgin Material

Non-toxic and environmentally friendly virgin material with a solid and sturdy texture, excellent temperature and weather resistance, no odor, and resistance to chemical corrosion.

02 Handle High-Strength Load-Bearing and Sway Test

The thickened hanging ear supports heavy loads, and the handle undergoes tens of thousands of full-load sway and tensile tests without breaking or detaching, ensuring safe and stable carrying.

03 Vertical Stacking Compression Test

The recessed non-slip bottom provides precise interlocking, and the bucket body features multiple reinforcing rings. It does not deform or collapse when stacked full, ensuring safe high-level storage.

04 Inverted Tilted Sealing Leak Test

The tamper-evident ring and double card slots interlock precisely for a tight seal. Even when filled with liquid and subjected to severe shaking and 360° inversion tests, it does not leak.

05 6-Meter High Drop Impact Test (20 kg Load)

Test height: 6 meters | Filled weight: 20 kg. After a high-altitude drop impact, the bucket lid remains tightly sealed, and the bucket body absorbs energy with its toughness without breaking or cracking.

06 Long-Term Weathering and Aging Test

After being placed at room temperature for several continuous months, the bucket body material shows no performance degradation, does not become brittle, and does not leak, making it suitable for long-term storage and turnover.
