YANGRUI Different Lunch Plastic Compartment Boxes for Food Packaging

I. Product Material Characteristics and Specifications Analysis

1.1 Main Material System and Technical Features

YANGRUI lunch prep boxes utilize three core material systems, all made from brand-new, food-grade raw materials. They reject any recycled, regenerated, or miscellaneous materials, fully complying with food safety requirements. Each material possesses unique technical characteristics, adaptable to different takeout and catering scenarios:

• PP (Polypropylene) material is YANGRUI's flagship product and the most commonly used material in takeout delivery and catering wholesale. It boasts excellent heat resistance and chemical stability. PP material has a temperature resistance range of -20℃ to +120℃ and is the only plastic material that can be heated in a microwave oven. After heating, it is odorless, does not easily soften, and maintains its shape. This material complies with FDA 21 CFR 177.1520 standards, is BPA-free, ensuring food safety, and also possesses good toughness and transparency, allowing for clear display of food. It is oil-resistant and leak-proof, suitable for holding various hot foods, staple foods, and side dishes, and adaptable to most takeout and group meal scenarios. Furthermore, PP material is recyclable, meeting basic environmental protection requirements. Its density is approximately 0.9 g/cm³, and its lightweight design facilitates food delivery while reducing transportation costs.
• The MFPP (Modified Filled Polypropylene) series adds 40% natural mineral filler (mainly calcium carbonate) to PP, not only reducing the amount of plastic used and practicing environmental protection, but also improving the product's rigidity and heat resistance. Compared to ordinary PP plastic, it is more resilient and less prone to breakage during transportation. MFPP material retains all the advantages of PP, with a temperature range of -20℃ to +120℃, allowing for microwave heating and refrigerated storage. It also offers better dimensional stability and surface smoothness, resulting in a superior surface texture. It is particularly suitable for customized products requiring intricate printing and is suitable for mid-to-high-end restaurants, brand chain takeout, and other scenarios. Its black version also has oil-resistant properties, making it aesthetically pleasing and stain-resistant, suitable for holding stir-fries, stews, meats, and other oily foods.
• PET (polyethylene terephthalate) packaging is primarily used for transparent packaging products. It boasts extremely high transparency (over 90% light transmittance) and excellent barrier properties, clearly showcasing the original appearance of food and enhancing appetite. With a temperature resistance range of -20℃ to +60℃, while it cannot be heated in a microwave, its superior display effect makes it an ideal choice for packaging fruits, salads, cold dishes, and fresh produce. It is suitable for light meal delivery, fresh food delivery, and cold food wholesale scenarios.

All YANGRUI's plastic compartment boxes for food undergo rigorous quality control, implementing a three-tiered testing standard: mandatory inspection of incoming raw materials, inspection during production, and full inspection of finished products before shipment. Each batch undergoes random sampling for heavy metals and evaporation residue, with zero exceedances. It complies with GB 4806.7-2023 "National Food Safety Standard - Plastic Materials and Products for Food Contact," ensuring product safety and controllability, and meeting the stringent standards of the catering industry.

1.2 Square Plastic Compartment Boxes for Food Series (13-47oz)

The transparent PP material allows for a clear display of the food, enhancing the consumer experience. Suitable for a la carte dishes in catering wholesale.
• The 2-compartment design is one of the most popular sizes in the takeout market, especially suitable for the "one dish, one rice" combination in Chinese cuisine. The compartmentalized design effectively prevents food from mixing flavors. The black base effectively hides stains, keeping the product clean and suitable for the bulk purchasing needs of fast food chains and small takeout shops.
• The 3-compartment option is primarily designed for scenarios requiring more diverse menu options, such as business set meals, fitness meals, and group meals. It packages dishes separately, ensuring a balanced nutritional profile and meeting diverse dining needs. It is suitable for wholesale purchases by mid-to-high-end catering companies and group meal companies.

1.3 Rectangular Plastic Compartment Boxes for Food Series (34-47oz)

This rectangular compartment box series offers greater variety in capacity and number of compartments, providing a complete selection from 1 to 5 compartments. Available in flat and tall lids, it adapts to the packaging needs of different dishes and is one of the most widely used series in food wholesale and takeout delivery. Specific parameters are as follows:

The core advantage of this rectangular compartment box is the choice of flat or tall lids, catering to the packaging needs of different dishes: The flat lid design (standard height 48mm) is suitable for solid foods such as fried rice, fried noodles, pizza, and solid side dishes; stacking saves space and reduces storage costs for catering businesses. The tall lid design (up to 66mm) is suitable for scenarios requiring more soup, sauces, or larger foods, such as set meals with soup, stews, and dishes with sauces; it effectively prevents spills and improves the delivery experience.

Made of PP material, it is microwave-safe and refrigerated. The lid design ensures good sealing, making it suitable for medium to large portion sizes of specialty food.
• Small oval-shaped food containers are available in three sizes: 1 compartment (12-16oz, approx. 350-470ml), 2 compartments (12-24oz, approx. 350-700ml), and 3 compartments (12-32oz, approx. 350-950ml). Made of PP material, the transparent lid allows for the display of food items. Suitable for small portions, snacks, desserts, and light meals.

The core advantage of the oval design is its ergonomic shape, providing a more comfortable grip, making it particularly suitable for delivery scenarios. Its stylish and attractive appearance enhances the visual image of food and beverage brands, distinguishing it from conventional square and rectangular containers. It is ideal for wholesale purchases by specialty restaurants, online celebrity takeout vendors, and dessert shops. YANGRUI's oval products are primarily available in two main sizes: 600ml three-compartment and 650ml two-compartment. The lid is detachable from the container body for easy food storage and cleaning (if reusable), while excellent sealing performance prevents leakage during delivery.

II. Export Compliance Analysis

YANGRUI, as a manufacturer specializing in export-oriented disposable food packaging, strictly adheres to the compliance requirements of major global export markets for its lunchbox plastic dividers. Having passed multiple international certifications, it ensures smooth customs clearance and meets the export needs of commercial procurement, especially for core export markets such as the United States and the European Union, with comprehensive compliance guarantees.

2.1 US Market Compliance Requirements

The US market has extremely stringent regulatory systems for single-use food packaging. YANGRUI's plastic compartment boxes for food fully meet its multi-level compliance requirements, allowing them to smoothly enter the US market and meet the export needs of food service, wholesale, and takeout delivery products:

• FDA (Food and Drug Administration) certification is a fundamental requirement for entering the US market. All YANGRUI lunch plastic compartment boxes for food have passed FDA food contact material certification, complying with 21 CFR 177 standards. Specifically, PP material products comply with 21 CFR 177.1520 standards, and MFPP material products also comply with this standard, ensuring that under normal use conditions (such as microwave heating and holding hot food), no harmful substances will migrate into food, guaranteeing food safety and fully complying with US hygiene requirements for food contact materials.
• State-level environmental regulations are equally important. Since May 2025, the FDA has completely banned greaseproof packaging materials containing PFAS (per- and polyfluoroalkyl substances). All YANGRUI's lunch plastic compartment boxes are PFAS-free, fully complying with this latest requirement and allowing for compliant sales in states with strict plastic restrictions, such as California and New York. Furthermore, YANGRUI's PP and MFPP products are recyclable, aligning with the environmental trends in the US market and eliminating concerns about customs clearance issues due to environmental concerns.

2.2 EU Market Compliance Requirements

The EU market has a similarly stringent regulatory system. YANGRUI's lunch plastic compartment boxes have passed multiple EU certifications, ensuring free circulation in the EU market and meeting the wholesale needs of catering businesses exporting to EU countries:

• LFGB (German Food and Consumer Goods Act) certification is a prerequisite for entering the German and EU markets. All YANGRUI products have passed LFGB certification, one of the strictest food contact material certifications in the EU. This certification not only requires products to comply with overall EU standards but also to meet specific German requirements, including strict limits on heavy metals and bisphenol A (BPA) in materials, ensuring product safety and compatibility with the food service industry standards of various EU countries.
• CE certification is mandatory in the EU market. YANGRUI's lunchboxes have obtained CE certification, complying with EU directives on food contact materials. This ensures the free circulation of the product throughout the EU market and is a crucial indicator of product compliance, providing compliance assurance for commercial procurement orders exported to the EU.

2.3 Other International Market Certifications

Besides the two major markets of the US and EU, YANGRUI's lunchboxes have also obtained other important international certifications, covering multiple export markets globally, providing comprehensive assurance for the export needs of commercial procurement:
