Food Grade Insulation 3mm Polypropylene PP Sheet For Chopping Board Manufacturing​

PP sheets (polypropylene sheets) are used in manufacturing food-safe trays and cutting boards, with core advantages of strong chemical stability, impact resistance, and easy cleaning. They can simultaneously meet the safety requirements for food contact and the durability needs for daily use. The specific benefits are categorized into four types as follows.

1. Core Advantage

• Food-contact-grade material: Complies with international safety standards such as FDA (U.S. Food and Drug Administration) and EU 10/2011 (EU Regulation on Food Contact Materials). It does not release toxic substances (e.g., plasticizers, heavy metals) at room temperature and medium-low temperatures (usually -20°C to 120°C), thus preventing food contamination.
• Odorless and non-odor-absorbing: The material itself is odorless and does not absorb grease, fishy smells, or other odors from food. This avoids cross-taste between different ingredients, making it particularly suitable for trays or cutting boards used in scenarios like fresh food, cooked food, and baking.

2. Durability and Damage Resistance

• Impact-resistant and unbreakable: PP sheets have good toughness and are not prone to cracking or breaking when subjected to external impacts (e.g., tray stacking, chopping on cutting boards). Their service life is much longer than that of traditional wooden, ceramic cutting boards or ordinary plastic sheets.
• Wide temperature resistance range: They can withstand low temperatures of -20°C (suitable for refrigerator cold storage/freezing trays) and high temperatures of 120°C (can be briefly cleaned with hot water, and some modified PP can withstand higher temperatures). They are not easily deformed under high temperatures, adapting to the temperature requirements of various food processing scenarios.

3. Easy Cleaning and Low Maintenance

• Smooth surface and non-water-absorbent: The surface of PP sheets is dense and non-porous, so they do not absorb water or trap dirt like wooden cutting boards, nor do they easily breed bacteria (e.g., E. coli, Salmonella), reducing food safety risks.
• Easy to rinse and chemical-resistant: They can be directly rinsed with clean water or food-grade detergents, and are even compatible with dishwasher cleaning. Meanwhile, they are resistant to most weak acid and alkali detergents (e.g., dish soap) and will not suffer surface damage or material aging due to chemical corrosion.

4. Lightweight and Processing Flexibility

• Lightweight: The density of PP material is approximately 0.9g/cm³ (lower than water), so the trays made from it are lightweight, facilitating manual handling or automated assembly line transportation and reducing logistics costs.
• Easy to process and shape: Through processes such as injection molding, cutting, and welding, it can be made into trays (e.g., with partitions, non-slip patterns) or cutting boards (e.g., round, square) of different sizes and shapes, adapting to the storage and processing needs of different foods.
