PP Plastic Butter Bucket

Polypropylene (PP) plastic butter buckets have become the preferred packaging choice for dairy producers, bakeries, and food service operators demanding reliable performance combined with cost efficiency. Made entirely from food-grade polypropylene, these containers deliver exceptional durability, chemical resistance, and superior moisture barrier properties. The material withstands a wide temperature range from -20°C to 120°C, making it suitable for cold storage, ambient distribution, and even microwave reheating when lids are removed. Unlike traditional polyethylene options, PP offers higher rigidity and excellent resistance to fats and oils, ensuring the structural integrity of the bucket remains intact even when filled with rich butter blends.

Key Product Parameters

• Material: 100% virgin food-grade polypropylene (PP), BPA-free, compliant with FDA 21 CFR 177.1520 and EU Regulation No 10/2011.
• Capacity options: 150g, 250g, 454g (1lb), 500g, 750g, 1kg, 2kg, and 5kg net weight butter content.
• Color: Natural translucent white, custom colors available upon request with minimum order quantities.
• Shape: Round cylindrical design with a slight taper for easy nesting and denesting during automated filling.
• Wall thickness: 0.7mm to 1.2mm depending on capacity, ensuring crush resistance while optimizing material usage.
• Lid type: Snap-on tamper-evident lid with breakaway tab, available in polyethylene or polypropylene, with optional inner sealing membrane.
• Printing: In-mold labeling (IML) for premium decoration, or offset dry printing up to 6 colors for direct container branding.
• Stackability: Interlocking base and lid design allows secure stacking during transport and retail display without additional dividers.
• Temperature resistance: Safe for freezer storage down to -20°C and lid-off microwave usage up to 120°C for softening butter.

Superior Barrier Properties

The polypropylene butter bucket integrates a reliable moisture barrier that prevents butter from picking up off-flavors and protects against oxidation. For extended shelf life requirements, an optional EVOH barrier layer can be incorporated through coextrusion technology, reducing oxygen transmission rates to below 0.5 cc/m²/24h at 23°C and 50% relative humidity. The tight-fitting lid features a silicone-free gasket seal that achieves a leak-proof closure, maintaining freshness during long-distance shipping and on retail shelves.

Manufacturing Precision and Quality Assurance

Every PP butter bucket is injection molded using high-speed automatic lines equipped with robotic part removal and vision inspection systems. Our quality management system is certified under ISO 9001:2015 and BRCGS Packaging Materials standards. Incoming resin undergoes melt flow index testing, and finished containers are subject to drop tests, top load compression analysis, and dimensional checks using coordinate measuring machines. Each batch is sampled for migration testing according to EU Regulation 10/2011 to guarantee food safety. Production lot traceability is maintained through date coding on each container, allowing full backward traceability to raw material batches.

Customization and Branding Options

We offer comprehensive decoration services to align the bucket with your brand identity. In-mold labeling embeds a fully printed polypropylene label during the molding process, making it resistant to scuffing, moisture, and refrigeration condensation. Dry offset printing directly on the container wall delivers vibrant, high-resolution graphics for logo, nutritional information, and usage instructions. Additional custom features include embossed measurement markings inside the bucket, colored lids, and custom-shaped handles for larger 2kg and 5kg formats. Our design team supports full artwork development and 3D mock-up generation within 48 hours of receiving your brief.

Sustainability and Recycling

Polypropylene butter buckets are fully recyclable and classified under resin identification code 5. We encourage a circular economy approach through lightweighting programs that reduce material consumption without sacrificing structural integrity. Post-industrial regrind can be reintroduced into the manufacturing stream for non-food contact layers in multi-layer constructions. All production scrap is collected, ground, and repurposed internally, maintaining a zero-waste-to-landfill operation. The compact nesting design also reduces shipping volume, lowering carbon emissions from logistics by up to 30% compared to heavier glass or non-nestable alternatives.
