Key Product Advantages
1.Superior Food-Grade Safety
The PVF coating ensures full compliance with international food contact standards. It is non-toxic, solvent-free, and odorless, preventing any chemical migration into food or pharmaceutical products.
2.Outstanding Chemical and Corrosion Resistance
The fluoropolymer layer exhibits strong resistance to acids, oils, alcohols, and alkaline substances. It maintains performance stability even under extreme storage or transport conditions.
3.Non-Stick and Easy-Clean Surface
The PVF surface prevents residue buildup, making the drum interior easy to clean and reusable. This is particularly useful for edible oils, flavorings, or pharmaceutical ingredients.
4.Enhanced Temperature and UV Durability
The coating’s fluoropolymer structure withstands high curing temperatures and ultraviolet exposure without discoloration or degradation, ensuring long-term coating stability.
5.Distinct Medium Green Identification
The unique medium green tone clearly identifies the drum as food-grade or high-purity safe, allowing for easy visual inspection in production or logistics environments.
6.Eco-Friendly Manufacturing
Using phosphorus-free pretreatment and water-based exterior paints, the production process meets modern environmental standards while maintaining full recyclability of the drum.
Product Composition and Structure
1.Each Medium Green PVF Coating Steel Drum consists of the following main components

Cosmetics & Personal Care: Creams, essential oils, and emulsions requiring non-reactive containers.
Fine Chemicals: High-value reagents and materials needing inert storage conditions.
Export Packaging: Fully compliant with international standards for food contact and transport.
These drums are ideal for long-term storage, cross-border shipping, and bulk transport where contamination-free performance is essential.
Quality Assurance
Every drum undergoes strict quality control procedures to ensure international compliance and durability:
Coating adhesion and uniformity testing
Chemical resistance verification (acids, alcohols, oils)
Food contact migration testing (FDA & EU standards)
Pressure and leak-proof testing
Salt spray corrosion testing
Visual and color uniformity inspection
All tests are conducted under ISO 9001 certified systems, with complete traceability of production batches.
Frequently Asked Questions (FAQ)
Q1: Why use PVF coating instead of epoxy or phenolic coatings?
PVF provides higher chemical inertness, purity, and long-term stability, ensuring no taste or odor contamination in food-grade applications.
Q2: Is the medium green color food-safe?
Yes. The pigment and polymer composition are certified for food contact, serving as a visual identification of compliant food-grade coating.
Q3: Can these drums be reused?
Yes. The non-stick surface allows easy cleaning and reuse without compromising coating integrity.
Q4: Are they suitable for export to Europe and North America?
Absolutely. The PVF drums comply with FDA and EU food packaging standards and are widely accepted internationally.
Q5: Can I customize exterior design or markings?
Yes. Wuxi Sifang provides custom painting, labeling, and logo services upon request.
