PP material has a stable molecular structure. It is not easy to decompose harmful substances under normal temperature and general usage conditions, nor does it easily react with ingredients such as acids, alkalis, and oils in food, thus effectively preventing food from being contaminated. Our PP sheets can withstand temperatures ranging from approximately -20℃ to 120℃. The high-temperature resistance of PP boards gives them significant advantages and practical value in food packaging.
Excellent Performance
Firstly, adapting to high-temperature processing links is a core highlight. Many stages in food production involve high-temperature treatments, such as hot filling (for soups, sauces, hot drinks, etc.), pasteurization, or retort sterilization. PP boards can withstand temperatures of 100-120°C without deformation, melting, or releasing harmful substances, ensuring packaging remains structurally stable during processing and preventing food contamination.
Secondly, they extend food shelf life. High-temperature sterilization is key to prolonging the shelf life of perishable foods. PP boards maintain stability in high-temperature sterilization environments, avoiding material aging or reduced sealing due to heat. This effectively blocks external bacterial intrusion, aiding long-term food preservation.
Thirdly, they enhance usability. For foods requiring secondary heating (such as microwaveable pre-prepared meals and ready-to-eat products), packaging made from PP boards can be directly placed in high-temperature environments like microwaves without needing container replacement. This simplifies consumer usage and avoids safety risks from heat-intolerant packaging.
Additionally, they ensure food safety. PP boards have stable chemical properties at high temperatures, without decomposing into toxic or harmful substances that migrate into food. They meet safety standards for food contact materials, providing reliable protection for food quality.
Multiple Applications
In specific applications, the high-temperature resistance of PP boards is widely used. In hot-filled food packaging, they are often used for sauces like tomato paste, jam, and chili sauce, as well as hot drinks such as hot juice and soy milk. Their heat resistance ensures packaging doesn’t deform during filling and maintains a tight seal to prevent leakage.
In retort food packaging, they are suitable for making retort pouches and high-temperature sterilization boxes, used for packaging zongzi, canned meat, and eight-treasure porridge—foods requiring high-temperature retort sterilization. They withstand the heat during retorting, ensuring packaging integrity and food sterility.
In microwave-heatable food packaging, they are made into microwaveable meal boxes and ready-to-eat food trays, allowing consumers to directly heat packaged food in microwaves without concerns about packaging damage or harmful substance release.
Moreover, in industrial food processing turnover, turnover boxes and trays made from PP boards are used for transporting semi-finished or finished food products in high-temperature environments. They tolerate the heat in processing workshops, are reusable and durable, reducing enterprise packaging costs.
Comparison of Different Materials in Food Packaging
| Material | Advantages | Disadvantages |
| PP (Polypropylene) | 1. Good temperature resistance (can withstand 100-120℃, suitable for microwave heating) | 1. Easy to deform at high temperatures, and may release trace harmful substances after long-term use |
| 2. Lightweight, easy to transport and carry | 2. Susceptible to corrosion by strong oxidizing substances, with limited service life | |
| 3. Strong chemical stability and excellent processability, can be made into various shapes (such as lunch boxes, bottles, cans, etc.) | 3. The recycling system is not perfect | |
| Paper Box | 1. Good environmental protection, easy to degrade, and friendly to the environment | 1. Poor water resistance; easy to be damaged by moisture if not compounded with other materials |
| 2. Excellent printing performance, enabling rich patterns and information display | 2. Low strength and weak impact resistance, with limited ability to protect food | |
| 3. Lightweight and low cost | 3. Poor sealing, making it difficult to preserve perishable food for a long time when used alone | |
| 4. Can be compounded with other materials (such as aluminum foil, PE film) to improve barrier and moisture resistance | ||
| Metal | 1. Extremely strong barrier property, effectively isolating oxygen, light and moisture, greatly extending the shelf life of food | 1. Heavy weight, increasing transportation costs |
| 2. High strength and good impact resistance, protecting food from physical damage | 2. High cost, especially uneconomical for small packaging | |
| 3. Recyclable and reusable, with certain environmental value | 3. Susceptible to corrosion (e.g., acidic food may rust tinplate), requiring inner wall treatment | |
| 4. Resistant to high temperature and pressure, suitable for packaging food requiring high-temperature sterilization | 4. Poor transparency, making it impossible for consumers to directly observe the state of internal food | |
| Glass | 1. Excellent chemical stability, no reaction with food at all, high safety | 1. Heavy weight, resulting in high transportation costs |
| 2. Good transparency, convenient for consumers to observe the state of food | 2. Poor impact resistance, easy to break | |
| 3. Reusable with high recycling rate | 3. High cost, especially for glass containers with special shapes | |
| 4. High temperature resistance, suitable for hot-fill food and microwave heating | 4. Strong thermal conductivity, easy to scald hands when containing high-temperature food |
