Food-grade Filter Paper

Bofeng New Materials' food-grade filter paper is specifically engineered for precision filtration in the food and beverage industries. Manufactured strictly from food-safe materials, it delivers precise filtration accuracy, superior wet strength, and rapid flow rates. This makes it the ideal filtration medium for enhancing product clarity while safeguarding flavor and safety.

Product Features

• 100% Food Safety Assurance
  • Crafted from premium virgin food-grade fiber materials, free from fluorescent whitening agents, dyes, and any other harmful migratory substances.
  • Fully compliant with national standards, ensuring a safe and worry-free filtration process.
• Precise Filtration Accuracy and High Efficiency
  • By controlling fiber ratios and production processes, we offer multiple precision ranges from coarse to fine filtration (e.g., 10μm - 50μm), effectively intercepting impurities of varying particle sizes such as tea dust, coffee grounds, oil suspensions, yeast, and fruit pulp fibers.
  • Optimized pore structure achieves faster filtration flow rates while maintaining precision, enhancing production efficiency.
• Superior Wet Strength
  • Maintains excellent mechanical strength even when fully saturated, resisting damage or tearing.
  • Ensures filter paper integrity during pressurized filtration or prolonged immersion, preventing filtration failure and product loss due to leaks.
• High Porosity and Low Resistance
  • The paper's fluffy structure provides high porosity and large dust-holding capacity, enabling it to load more impurities, extend effective filtration time, and reduce replacement frequency.
  • Low filtration resistance facilitates rapid filtration under natural gravity or low-pressure conditions, saving energy consumption.
• Exceptional Flavor Retention
  • Made from inert fiber materials that do not adsorb or extract flavor compounds from food and beverages. Ensures the smooth passage of active components like tea polyphenols, caffeine, and aromatic compounds, perfectly preserving the original flavor and quality of the product.
• Excellent Compatibility
  • Highly compatible with various acidic, neutral, and weakly alkaline food liquids. Maintains stable performance without causing chemical reactions.

Primary Applications

Bofeng Food-Grade Filter Paper is an indispensable key consumable in numerous food and beverage processing applications.

• Tea Industry:
  • Tea Bags: Used in various shaped tea bags for rapid brewing and exceptional infusion clarity.
  • Tea Extract Filtration: Filters tea extracts during industrial beverage production, removing tea residue to ensure sediment-free products.
• Coffee Industry:
  • Drip Coffee Pouches: Serves as the core material for drip coffee pouches, preventing coffee grounds leakage during brewing while allowing full release of coffee oils and aromatic compounds.
  • Coffee Liquid Fine Filtration: Used for final filtration in products like cold brew coffee and espresso concentrates.
• Edible Oil and Fat Industry:
  • Primary filtration of crude oils (e.g., rapeseed oil, peanut oil) to remove phospholipids, saponins, and other solid impurities.
• Wine and Brewing Industry:
  • Beer: Filters residual yeast and proteins to enhance beer clarity and biological stability.
  • Sake, rice wine, and other fermented alcoholic beverages: Used for clarification filtration of the liquor.
• Juice and Beverage Industry:
  • Used for filtering clarified juices (e.g., apple juice, grape juice) to remove pulp fibers and suspended solids, yielding clear, transparent juice products.
  • Used for filtering various syrups and concentrated juices.
• Condiments and Food Additives:
  • Used for clarifying filtration of condiments like soy sauce, vinegar, and monosodium glutamate solutions, as well as food additives such as gelatin and pectin.
