Core Material Advantages: Why Resin Code #5 PP Leads the Range
Most of our meal prep, fresh-keeping and fast food containers use food-grade polypropylene (PP, resin code #5). PP has a melting point of about 165 °C and a heat deflection temperature of up to 130 °C. It is the plastic most widely recognized as suitable for short microwave heating, it resists oils and mild acids, and it does not release Bisphenol A (BPA). Where display clarity matters more than heat resistance, such as cold dessert boxes and clear cups, we also supply PET (resin code #1), which gives the highest transparency but is intended for ambient and refrigerated use only.
Common Food-Contact Plastics Compared
| Resin Code | Material | Approx. Heat Resistance | Microwave | Typical Use |
|---|---|---|---|---|
| #1 | PET | ~70 °C | Not recommended | Clear cups, cake boxes, salad containers |
| #2 | HDPE | ~130 °C | Generally safe | Milk bottles, yogurt cups |
| #3 | PVC | ~80 °C | Not safe | Cling film |
| #4 | LDPE | ~90 °C | Not safe | Bags, film |
| #5 | PP | ~130 °C | Safe (short heating) | Meal prep, storage and fast food boxes |
| #6 | PS | ~80 °C | Not safe | Instant noodle cups, foam trays |
| #7 | Other / PC | Varies | Not safe | Some bottles; may contain BPA |
Choosing the Right Container by Application
Start from the food, the filling temperature and the sales channel, then match the product family and resin. The table below summarizes how our five families map to the most common programs.
| Application | Recommended Family | Typical Material | Key Selection Point |
|---|---|---|---|
| Food delivery and takeaway | Fast Food Box | PP | Snap-lock seal, leak resistance, stackable for carriers |
| Meal prep and school lunch | Fast Food Box (bento) | PP | Compartment layout, microwave-safe marking, lid venting |
| Refrigerator and leftovers | Fresh-keeping Box | PP | Airtight lid, freezer-to-fridge range, easy cleaning |
| Pantry, retail and display | Storage Box | PP or clear resin | Stackability, handle and lid design, transparency |
| Beverages and events | Cups & Plates | Food-grade clear resin | Clarity, rim strength, hot or cold use |
| Bakery and dessert | Cake Box | PET or PP | Display clarity, top-load strength, closure type |
Key Product Features
-
Snap-lock seal design: precise lid and body fit with sealing ribs to reduce leakage during transport.
Microwave-safe PP models: look for the microwave symbol on the base and follow the heating guidance below.
UV anti-yellowing option: transparent models can include UV stabilizers to keep clarity under indoor light.
Lightweight walls: thin-wall injection molding keeps unit weight low and reduces freight cost.
Nesting and stacking: standardized profiles let empty containers nest to save warehouse and container space.

PP vs PET at a Glance
Indicative relative rating (1 to 5) of the two main resins; PP leads on heat and toughness, PET on clarity.
Lightweight, Nestable and Carton-Efficient
Standard PP meal prep sizes keep wall weight low and carton counts high, which lowers freight cost per container.

Unit Weight by Capacity
Unit weight rises steadily with capacity in our PP meal prep range.
Customization, Tooling and the OEM / ODM Workflow
As an OEM and ODM factory with in-house mold development, we adjust capacity, size, color (white, black, transparent or Pantone matching), logo printing, lid structure, compartment layout and carton packing to each project. Injection molding and thermoforming run on the same site, and in-mold labeling is available for premium retail finishes.

Usage and Selection Recommendations
- Check the resin code on the base and prefer products marked #5 PP or Microwave Safe for reheating.
- Inspect samples for smooth surfaces, even color and no odor or impurities.
- Heat in short intervals at medium-low power, no more than 3 minutes per session.
- Avoid storing strongly acidic or alkaline foods for long periods.
- Stop using any container that shows cracks, deformation or discoloration.
Frequently Asked Questions
Are your plastic food containers microwave safe?
Our PP containers (resin code #5) are suitable for short microwave heating. Confirm the microwave-safe symbol on the base, loosen or remove the lid to vent steam, use medium-low power and heat for 1 to 3 minutes at a time. PET products such as clear cake boxes and cups are for ambient and refrigerated use only.
Will the lids leak when carrying soup or sauces?
Snap-lock models use precisely fitted lid and body profiles with sealing ribs, tested for vibration and tilt. Press the lid fully until it clicks to complete the seal.
Will transparent containers turn yellow?
Under normal indoor use, clear containers keep their transparency well, and UV-stabilized grades are available for longer display life. Avoid prolonged direct sunlight and storage near heat sources.
Do you support custom sizes, colors and printing?
Yes. We customize capacity, size, color, logo printing, compartment layout and carton packing, backed by in-house mold development for new cavity designs. Contact our sales team for minimum order quantities and sampling lead times.
Which certifications and standards do your products meet?
Our containers are produced to FDA, EU 10/2011 and GB 4806.7-2016 food-contact requirements, with SGS migration testing, ISO 9001 quality management, and BSCI and ICS certification. Batch reports are available on request.
Can PP containers be reused and how should they be cleaned?
Structurally intact PP containers can be washed and reused. Use warm water below 60 °C and neutral detergent, avoid steel wool, and dry fully before storage. Disposable-grade containers are designed for short-term use.
Sustainability and Global Service
We use virgin food-grade resin, optimize molding to reduce energy and scrap, and design stackable structures that lower transport emissions per container. PP is recyclable and reusable, and the real difference comes from correct use and responsible disposal. From needs analysis and sample prototyping to mass production and logistics, our team provides one-to-one service for each market.
