5L Extra-Thick Industrial Plastic Pail (1.3mm Wall Thickness + Leak-Proof Seal) | Packaging for Paints, Coatings, Sealants, and High-Viscosity Liquids

This 5L thickened industrial plastic packaging bucket is specially designed for packaging paints, coatings, construction sealants, and various high-viscosity liquids. The bucket is made from 100% brand-new, high-quality virgin PP (polypropylene) material through high-pressure injection molding, with a wall thickness of 1.3 mm (1.3mm thickened design). It offers excellent mechanical rigidity and high impact toughness, easily withstanding multi-layer heavy-duty vertical stacking pressure without cracking or deforming during rigorous factory handling, turnover, and bumpy transportation.

The core advantage of this bucket lies in its precision-matched leak-proof sealing lid system. The bucket mouth and lid rim feature a precision-fit interlocking groove design, forming a reliable airtight and watertight barrier when tightened. It effectively blocks external moisture from entering, prevents paint sloshing and spills, and stops the diffusion of volatile solvent odors, ensuring the chemical stability of the contents throughout its entire life cycle while significantly reducing material waste and pollution risks for paint manufacturers and professional construction contractors. Supports multiple OEM/ODM customization services, including in-mold labeling (IML), hot transfer printing, and screen printing.

Core Product Advantages

• 1.3mm thickened bucket wall, strong pressure resistance and anti-cracking: Made from high-toughness, high-quality virgin PP material through thickened injection molding, it is drop-resistant, impact-resistant, and resistant to environmental pressure loads, adapting to harsh working conditions and long-distance bumpy logistics.
• High-precision leak-proof sealing lid, locks in odors and prevents evaporation: The lid tightly fits and interlocks with the bucket mouth, preventing leaks even when inverted or tilted. It effectively suppresses the emission of organic solvent odors, prevents moisture and skinning, and maintains the best quality of the material.
• Ergonomic handle, convenient and safe handling: The bucket body is equipped with an integrated injection-molded reinforced hanging ear, paired with a comfortable-grip high-strength plastic or rust-resistant metal handle, making it effortless, stable, and secure to carry when full without pinching the hand or detaching.
• Large-diameter wide-mouth design, efficient filling and dispensing: The large-diameter structure is particularly convenient for the rapid mechanical filling and construction dispensing of high-viscosity sealants, thick paste coatings, and adhesives, allowing for smooth pouring without clinging to the walls.
• Multi-layer tight stacking, worry-free storage and transportation: The top of the bucket lid and the bottom groove fit precisely, preventing slipping and tipping when stacked high, greatly improving pallet loading capacity and container shipping space utilization.

Applicable Industries and Packaging Scenarios

• Paints, coatings, and architectural coatings: Interior and exterior wall latex paint, decorative coatings, floor paints, metal anti-rust paint, water-based wood coatings, and waterproof coatings.
• Sealing sealants and adhesives: Construction sealants, sealants, tile grouts, tile backing adhesives, water-based wood panel adhesives, and polyurethane adhesives.
• Industrial high-viscosity fluids and chemicals: Industrial resin emulsions, lubricants and greases, paste materials, concentrated cleaning agents, and additives.

Specifications and OEM/ODM Customization Instructions

Strict Quality Inspection and Factory Testing

All Fono packaging buckets undergo strict industrial-grade quality inspection standards before leaving the factory to ensure load-bearing durability and reliable protection:

01 Brand-new Polypropylene (PP) Virgin Material

Non-toxic and environmentally friendly virgin material, solid and sturdy, with excellent temperature and weather resistance, odorless, and resistant to chemical corrosion.

02 Handle High-Strength Load-Bearing and Swing Test

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

03 Vertical Stacking Pressure Test

The lid and bottom fit together with anti-slip positioning, 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 anti-theft ring and double snap slots interlock precisely for sealing. Even when full of liquid and subjected to severe agitation and 360° inversion tests, it does not leak.

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

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

06 Long-Term Weathering and Aging Test

After being placed at room temperature for several continuous months, the bucket body material properties do not deteriorate, it does not become brittle or leak, and is suitable for long-term storage and turnover.
