Since 2016, Ningbo Panfeng Mould Plastic Co., Ltd. has been dedicated to the research, development, and production of food-grade plastic meal prep containers. With over 10 years of industry experience and an export network spanning more than 90 countries and regions, we have become a trusted global partner for food packaging solutions. We utilize 100% food-grade PP (polypropylene) raw materials combined with advanced injection molding processes to deliver safe, durable, and eco-friendly food packaging solutions for our clients. All products have passed international certifications including FDA, EU 10/2011, and SGS heavy metal migration testing, ensuring that every container meets the most stringent food safety standards.
Our containers are manufactured using food-grade PP (polypropylene, resin code #5), widely recognized as one of the safest plastics for microwave heating. PP has a melting point as high as 165 degrees Celsius and a heat deflection temperature of up to 130 degrees Celsius, making it safe for short-term microwave heating (recommended heating time not exceeding 3 minutes). Compared to PS (polystyrene) and PET (polyethylene terephthalate), PP offers superior heat resistance and chemical stability, and does not release harmful substances such as Bisphenol A (BPA) during heating.

Understanding the resin identification codes on the bottom of plastic food containers is the first step in ensuring food safety. As a professional manufacturer with over 10 years of industry experience, Ningbo Panfeng Mould Plastic Co., Ltd. always prioritizes material safety. Our entire product line uses resin code #5 PP material, ensuring that every stage from raw materials to finished products meets international food safety standards.
| Resin Code | Material Name | Heat Resistance | Microwave Safe | Typical Applications | Usage Notes |
|---|---|---|---|---|---|
| #1 | PET / PETE | ~70 degrees Celsius | Not Safe | Beverage bottles, salad containers | Avoid hot drinks, alcohol, oily foods |
| #2 | HDPE | ~130 degrees Celsius | Generally Safe | Milk bottles, yogurt cups | Difficult to clean thoroughly, not recommended for reuse |
| #3 | PVC | ~80 degrees Celsius | Not Safe | Cling film | Avoid contact with high-temperature, high-fat foods |
| #4 | LDPE | ~90 degrees Celsius | Not Safe | Cling film, plastic bags | Low heat resistance, do not use in microwave |
| #5 | PP (Polypropylene) | ~130 degrees Celsius | Safe | Microwave containers, food storage boxes | Only microwave-safe plastic, reusable after cleaning |
| #6 | PS (Polystyrene) | ~80 degrees Celsius | Not Safe | Instant noodle cups, fast food containers | Do not microwave, avoid high-temperature foods |
| #7 | Other / PC | Depends on material | Not Safe | Water bottles, baby bottles | May contain BPA, use with caution |
All Ningbo Panfeng Mould Plastic Co., Ltd. products use resin code #5 PP material, currently the only food-grade plastic universally recognized as safe for microwave heating. PP offers excellent chemical resistance, heat resistance, and mechanical strength, is free of Bisphenol A (BPA), and does not release harmful substances under normal use conditions. Ningbo Panfeng Mould Plastic Co., Ltd. operates a modern injection molding production base equipped with fully automated injection molding lines, precision mold processing centers, and dust-free workshops. Annual capacity exceeds hundreds of millions of containers. We strictly implement the ISO9001 quality management system, ensuring a product qualification rate of over 99.5%.
A: Ningbo Panfeng Mould Plastic Co., Ltd. containers feature a patented snap-lock seal structure. The lid and body are designed with precision mold fitting, with dual sealing ribs around the perimeter. Verified through laboratory vibration testing (simulating transportation conditions) and tilt leakage testing, even when holding soup-based dishes (such as spicy hot pot or porridge), they maintain zero leakage during normal use and transportation. Ensure the lid is fully snapped into place during use; a "click" sound indicates a complete seal.
A: Ningbo Panfeng Mould Plastic Co., Ltd. transparent containers contain UV anti-yellowing stabilizers in the raw material. Under normal indoor lighting conditions for 6 months of continuous use, transparency retention remains above 90%. To extend the lifespan of transparent containers, avoid prolonged direct sunlight exposure and store away from high-temperature heat sources. If significant yellowing or clouding occurs, replace the container to ensure optimal food presentation.
A: As a professional plastic container manufacturer with over 10 years of industry experience, Ningbo Panfeng Mould Plastic Co., Ltd. is not merely a manufacturer but a trusted global partner for our clients. We provide full-chain customization services, including body/lid color customization (white, black, transparent, and Pantone color matching), size and capacity customization (adjustable according to client requirements), surface printing customization (Logo printing, brand patterns, usage instructions), and packaging customization (carton quantities and outer box printing per client request). Minimum order quantities and sampling lead times can be obtained by contacting our sales team.
A: All Ningbo Panfeng Mould Plastic Co., Ltd. products have passed multiple international authoritative certifications, including U.S. FDA food contact material certification, EU Regulation 10/2011 compliance, SGS heavy metal migration testing, and China GB 4806.7-2016 National Food Safety Standard. All raw materials come with complete traceability reports and test reports, ensuring that every step from raw material procurement to finished product dispatch meets food safety requirements. Ningbo Panfeng Mould Plastic Co., Ltd. maintains an independent product research and development center, continuously investing in the development of new eco-friendly materials, lightweight structures, and intelligent packaging technologies. We have obtained multiple utility model patents and design patents.
A: Ningbo Panfeng Mould Plastic Co., Ltd. PP containers can be cleaned and reused provided they remain structurally intact without cracks or deformation. We recommend washing with warm water (not exceeding 60 degrees Celsius) and neutral detergent, avoiding abrasive scrubbers such as steel wool. Dry thoroughly after cleaning before storage to prevent bacterial growth. If deformation, discoloration, or odor occurs after microwave heating, discontinue use immediately. Note that disposable containers are designed for short-term use; for long-term reuse, dedicated reusable food storage containers are recommended.
A: When using Ningbo Panfeng Mould Plastic Co., Ltd. PP containers for microwave heating, please observe the following: 1) Confirm the container bottom bears a microwave-safe symbol (three wavy lines or "Microwave Safe" text); 2) Slightly open or remove the lid before heating to allow steam venting and prevent lid deformation from pressure buildup; 3) Use medium-low power and limit each heating session to 1 to 3 minutes, with multiple short heating intervals if needed; 4) Avoid heating empty containers or high-fat foods for extended periods at high temperatures; 5) Container surfaces will be hot after heating; use oven mitts or thick cloth when removing.
Ningbo Panfeng Mould Plastic Co., Ltd. actively responds to global environmental initiatives by implementing a green production model: at the raw material stage, we use 100% food-grade virgin materials and reject recycled materials; at the production stage, we optimize injection molding processes to reduce energy consumption and waste generation; at the product stage, we design stackable structures to minimize transportation carbon footprints; and at the recycling stage, we promote the recyclability and reuse of PP materials. We believe that plastic itself is not the problem — the key lies in scientific management and proper usage.
Ningbo Panfeng Mould Plastic Co., Ltd. understands that different markets and scenarios demand different container functionalities — food delivery requires leak-proof and compression-resistant designs, airline catering demands lightweight and high-temperature resistance, and central kitchens need large-capacity stackable solutions. Accordingly, we provide full-cycle one-on-one services from needs analysis, solution design, sample prototyping to mass production and logistics delivery, ensuring each product precisely matches the client's actual application scenario. Ningbo Panfeng Mould Plastic Co., Ltd. is committed to working alongside global customers to advance sustainable development in the packaging industry while ensuring food safety.
