20L Food-Grade Square Plastic Pail (Tamper-Evident Sealable Lid + Reinforced Handle) | Multipurpose Packaging for Food Ingredients, Additives, and Fine Chemicals
This 20L food-grade square plastic packaging bucket is specially designed to meet the high-standard storage and transportation needs of premium brand customers. It strictly complies with food-contact safety standards and is precision injection-molded from 100% brand-new, high-impact-resistant, food-grade virgin polypropylene (PP). The pure, odor-free material offers excellent temperature and weather resistance, as well as chemical corrosion resistance, making it widely suitable for high-requirement food ingredients, fine chemical additives, high-value animal feed, household chemicals, and other industries.
The bucket features a classic regular square high-capacity design, which increases pallet stacking efficiency and warehouse space utilization by over 20% compared to traditional round buckets, while providing more stable long-distance transportation. Equipped with a tightly fitting tamper-evident pull-off sealing lid and reinforced ergonomic handles, it offers a tight, moisture-proof, and leak-proof seal, with tamper-evident opening for traceability. It is easy and safe to carry when fully loaded and supports comprehensive OEM/ODM branding and appearance customization.
Core Product Advantages
- Strictly compliant food-grade virgin material: Made from premium food-grade polypropylene (PP), it is non-toxic, odorless, environmentally friendly, durable, and resistant to acids, alkalis, and salts. It fully passes rigorous physical and chemical migration tests.
- Regular square design significantly optimizes transportation and storage: The square structure allows pallets and shelves to be stacked tightly without wasted gaps, greatly improving container loading efficiency and reducing overall ocean freight and warehousing logistics costs.
- Precision tamper-evident sealing lid, drip-proof: The high-sealing lid with a tamper-evident tear-off ring features strong locking slots, remains leak-proof when inverted 360°, and effectively prevents moisture and dust from entering, keeping the contents pure and stable.
- Reinforced ergonomic handles and non-slip stacking design: The thickened and widened hanging loops and handles have undergone high-frequency load-bearing swing tests, making them comfortable and secure to carry when fully loaded with 20 kg. The bucket lid features non-slip grooves and supports stable high-level vertical stacking.
- Comprehensive branding customization and large-format display: The flat square exterior provides ample visual display space and supports in-mold labeling (IML), hot transfer printing, and screen printing. The bucket and lid colors can be customized according to international Pantone color codes.
Suitable Industries and Applications
- Food ingredients and brewing seasonings: Food-grade edible syrups, essences and flavorings, liquid food additives, seasoning sauces, baking ingredients, and fruit concentrates.
- Fine chemicals and industrial additives: Specialty chemical additives, water-based resin additives, surfactants, latex preservatives, and liquid cleaning agents.
- Animal nutrition and modern agriculture: Premium concentrated animal feed, aquaculture health additives, veterinary medicine premixes, fermented probiotics, and trace element fertilizers.

Strict Quality Testing and Factory Inspection
All Fono packaging buckets undergo strict industrial quality inspection before leaving the factory to ensure durability under load and reliable protection:
01 Brand-new Polypropylene (PP) Virgin Material
Non-toxic, environmentally friendly virgin material with a solid and sturdy texture, excellent temperature and weather resistance, no odor, and resistance to chemical corrosion.
02 High-Strength Handle Load-Bearing and Swing Test
The thickened hanging loops support heavy loads, and the handles have undergone tens of thousands of full-load swing and tensile tests without breaking or detaching, ensuring safe and secure carrying.
03 Vertical Stacking Compression Test
The lid and base fit together with non-slip positioning, and the bucket body features multiple reinforcing rings. It does not deform or collapse when stacked full, ensuring safe high-level warehousing.
04 Inverted Tilted Leak-Proof Test
The tamper-evident ring and dual slots fit together precisely to create a tight seal. The bucket remains leak-proof even when filled with liquid and subjected to severe shaking and 360° inversion.
05 6-Meter High Drop Impact Test (20 kg Load)
Test Height: 6 meters | Contents Weight: 20 kg. After a high-altitude drop impact, the bucket lid remains tightly sealed, and the bucket body absorbs the impact with its toughness without breaking or cracking.
06 Long-Term Weathering and Aging Test
After being left at room temperature for several continuous months, the bucket material properties do not deteriorate, it does not become brittle or leak, and is suitable for long-term storage and transportation.
