1. Full Analysis of the Core Characteristics of MFPP, PP, And PET Materials
PP (Polypropylene)
PP is suitable for hot food packaging and microwave heating. It is a thermoplastic material widely used in the food packaging industry. It can withstand high temperatures up to 120°C, has strong toughness, can effectively withstand certain mechanical shocks, and will not deform easily. This type of material has a moderate cost and is suitable for mass-produced fast food packaging boxes.
- Advantages: high temperature resistance, safety, and non-toxicity, and high structural stability.
- Disadvantages: low transparency, easy to become brittle after refrigeration or long storage.
- Common applications: food box with compartments (such as double bento, three-compartment hot food box).
MFPP (Modified PP)
MFPP is modified polypropylene, which is usually improved by adding mineral fillers to improve its rigidity and heat resistance. The lunch box made of MFPP has a more textured appearance, often in black or matte surface design, with strong pressure resistance and high stability, suitable for use in high-end occasions, such as high-end catering, high-speed rail, aviation, conference catering, etc.
- Advantages: certain pressure resistance and heat resistance, oil-proof and anti-seepage, not easy to deform.
- Disadvantages: opaque, MFPP material cost is slightly higher.
- Common applications: custom to go food boxes, such as cabin bento, high-end takeaway meals.
PET (Polyethylene Terephthalate)
PET plastic is highly transparent, environmentally friendly, non-toxic, and recyclable, so it is very popular. It has good cold resistance, is very suitable for low-temperature storage, can be stored in the refrigerator, but does not support microwave heating. The display effect is excellent, and the food can be presented in bright colors. It is the first choice for all kinds of salads, fruit cups, and beverage boxes.
- Advantages: high transparency, environmentally friendly and recyclable, good display effect.
- Disadvantages: Cannot be heated, and the lunch boxes made of PET are more brittle than PP and MFPP.
- Common applications: salad boxes, fruit platters, PET plastic containers, supermarket refrigerated packaging.
3. How to Balance Price and Environmental Protection?
In addition to functionality, the unit cost, environmental performance, and recyclability of different materials are also important considerations for purchasers. The following is a cost-effectiveness comparison table of common disposable food box materials:
| Material | Cost | Recyclable | Whether heatable | Recommended scenario |
| PP | Low | Medium recycling rate | Support microwave heating | Fast food lunch, batch packaging |
| MFPP | Medium | Partially recyclable | Microwave-usable | Business packages, high-end customized takeaways |
| PET | High | High recyclability | Does not support heating | Salad, fruit, cold drink packaging |
If you value sustainable development and brand environmental protection concepts, then PET is a good choice, because PET is not only recyclable, but also can convey the brand's modernity and environmental awareness at the visual level.

2. How to Accurately Match Materials for Different Products?
The core logic of selecting materials is to make the material characteristics highly match the food properties to ensure safety, aesthetics, and user experience.
Scenario 1: Hot Food → PP or MFPP Is More Resistant to High Temperatures
Foods that need to be heated in a microwave or insulated are usually hot rice, baked rice, and soup powder. The key to choosing the right products for this type of product is heat resistance. As an economical and practical material, PP can be used in batches for fast food packaging, while MFPP is suitable for takeaway merchants who pursue brand sense and high-end user experience. The recommended product is custom to go food boxes, which are suitable for microwave heating, have strong sealing, and no leakage.
Scenario 2: Cold Food → PET Has the Best Display Effect
If cold food takeaways such as fruits, cold noodles, sushi, and salads are the products you need to sell, then PET transparent boxes can maximize the color and layering of the food. High transparency can enhance consumers' appetite, and the stackable performance is also more suitable for display in display refrigerators. This type of PET product is recommended to cold food box suppliers who focus on visual display and environmental protection.
Scenario 3: Multi-compartment Lunch Box → Choose PP or MFPP for Better Sealing
For lunch boxes that need to separate dishes, such as double rice, soup, and rice separation boxes, three-compartment business lunch boxes, etc., the structural strength and sealing of the material are very important. PP and MFPP both perform well in this regard and support mold diversification. Both molds, colors, and sizes can be customized, which is suitable for batch customization. It is recommended to be used in food boxes with compartments, which can improve food partitioning and avoid odor contamination.
4. How to Choose the Right Material and Structure When Customizing Food Boxes?
Customized lunch boxes not only need to choose the right material, but also need to combine product structure and brand positioning for overall design, so as to stand out from the competition of many lunch box brands.
- Lunch box shape: PP/MFPP is suitable for round or multi-grid structure, with a stable structure and resistant to stacking. PET is suitable for transparent display design, mostly used for salad and fruit boxes.
- Lid design: PP/MFPP is a mostly split lid, which is convenient for packaging and stacking. PET is often made into an integrated hinged lid to enhance the display sense and facilitate opening and closing.
- LOGO and brand printing: MFPP is suitable for embossing LOGO or matte texture to highlight the brand texture; PET is suitable for labeling or color printing, and transparent material makes LOGO clearer; PP is suitable for mass printing and is used for chain brand fast food customization.
Customized custom to go food boxes should be planned uniformly from structure, material, to packaging method, so as to take into account practicality, beauty, and brand communication.
