🟢A PC portion pot is a small container made of polycarbonate. It offers glass-like clarity and high impact resistance, making it difficult to break. Commonly used in catering and labs, it is ideal for portioning sauces, side dishes, or samples. 🔵It is durable and reusable, making it more economical and eco-friendly than disposable containers. With a wide temperature tolerance, it can be used for freezing and microwave heating. It is also dishwasher-safe, greatly improving work efficiency. 🟡In kitchens, chefs use it for dips or tasting samples. In buffets, it holds nuts, olives, or small snacks. Laboratories use it for storing or observing specimens. Schools also use it for art paints or craft supplies 🟠Heat-resistant at medium to high temperatures, safe, and non-toxic.
🟢A PC black portion pot is a food service container made of polycarbonate with black colorant. It retains the high impact resistance and temperature tolerance of standard PC, while its black appearance helps conceal uneven colors of the contents, making it suitable for specific applications. 🔵The black body effectively masks inconsistent shades of sauces, braised dishes, or semi-finished ingredients, improving visual presentation. It is durable, reusable, and dishwasher-safe, and can withstand freezing and microwave heating. Compared to white or clear pots, black pots look cleaner for longer and resist visible stains. 🟡These pots are widely used in Chinese fast food, delis, and barbecue stalls for dark sauces (such as gravy or black pepper sauce), marinated meats, or cold salads. In buffets, black pots darken the background, making light-colored foods like yogurt or salad dressing stand out more vividly. 🟠Always check that the product is labeled "BPA Free" and made from food-grade PC. Under prolonged UV exposure, black pots may fade slightly, so avoid storing them in direct sunlight. Use neutral detergents for cleaning to maintain their surface gloss and extend service life.
🟢A PPSU portion pot is a high-performance food container made of polyphenylsulfone (PPSU). This advanced engineering plastic is commonly used for baby bottles and medical devices. It offers superior heat resistance and chemical stability compared to PC and PSU. 🔵PPSU pots withstand repeated high-temperature steam sterilization (above 180°C) and microwave heating. They have excellent hydrolysis resistance, so they do not degrade easily from hot water or steam. They also provide high transparency, outstanding impact resistance, and better chemical resistance than PC, resisting yellowing even after long-term use. 🟡These pots are ideal for demanding environments such as medical catering, infant food portioning, sterile laboratories, and airline meal preparation. They are also a great choice for central kitchens or elderly care facilities that require frequent high-temperature disinfection. 🟠PPSU is significantly more expensive than PC or PSU. When purchasing, look for "PPSU" labeling and food-grade certifications such as FDA or LFGB. Although the initial cost is higher, its exceptional durability and BPA-free safety make it well worth the investment for premium applications.
🟢A PP portion pot is a food container made of polypropylene (PP). PP is a common food-grade plastic with low cost, widely used for disposable lunch boxes and microwave-safe tableware. It is opaque, typically appearing in translucent milky white or solid white. 🔵PP portion pots offer excellent chemical resistance against acids, alkalis, and oils, with minimal reaction to foods. They withstand temperatures up to around 120°C, supporting microwave heating and dishwasher cleaning, but are not suitable for high-temperature steam sterilization. The material is naturally BPA-free and safe for food contact. 🟡These pots are widely used in fast food restaurants, canteens, and meal prep services for rice, vegetables, soups, or cold dishes. Due to their low cost, they are also often used as disposable portion pots, replacing aluminum foil or paper containers. 🟠PP pots are opaque, so the contents cannot be seen directly. Their impact resistance is lower than PC pots, and they may crack if dropped hard. Over time, the surface can develop scratches. They are also not freeze-resistant, becoming brittle at low temperatures. Always check for "food-grade PP" labeling and temperature range specifications.
🟢A melamine portion pot is a food container made of melamine resin (melamine-formaldehyde) through high-temperature and high-pressure molding. It has a smooth, ceramic-like appearance, but is lighter and more break-resistant than ceramic. It is widely used in canteens, fast food restaurants, and buffets. 🔵Melamine pots are hard, smooth, and resistant to falling and scratching. Their temperature range is typically -20°C to 120°C, making them suitable for refrigeration and dishwashers, but not for microwaves or high-temperature steaming. Because melamine has low thermal conductivity, the pot does not get hot to the touch when holding hot food. 🟡These pots are commonly used in large canteens, school cafeterias, corporate group meals, and hot pot restaurants for rice, soups, stews, and fruits. With their porcelain-like appearance, they are also popular on Chinese banquet buffets, balancing aesthetics and durability. 🟠Melamine portion pots are not microwave-safe. High temperatures can degrade the material or cause chemical migration. Avoid using them for very hot oily foods (such as frying oil) or highly acidic foods. Always look for food contact material safety certifications (such as China's GB 4806.6) and choose products from reputable manufacturers.
