Thanks to PP material's advantages such as safety, temperature resistance, moisture resistance and low cost, it has become an ideal choice in the field of food packaging. It is widely used in the packaging of daily food, which not only ensures the safety and quality of food but also brings convenience to production and consumption.
Safety
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℃. They can be used for packaging refrigerated food and are also suitable for short-term heating in microwave ovens, making it highly practical. The molecular structure of PP material is dense with low air permeability, which can effectively block water and moisture, preventing food from getting damp and deteriorating. It is especially suitable for packaging moisture-sensitive foods such as biscuits, grains, and tea. Moreover, PP material has good impact resistance and toughness, is not easy to break, and can withstand a certain degree of extrusion and collision, protecting food from damage during transportation and storage.
portability and Convenience
PP material can be processed into packaging products of different forms through various processes such as injection molding, blow molding, and extrusion, which can meet the packaging specifications and form requirements of various foods. Its surface can be printed, facilitating the marking of food information. The density of PP material is approximately 0.90-0.91g/cm³, which is slightly lower than that of PE (polyethylene). The packaging products made from it are lightweight, which can reduce transportation costs and reduce the overall consumption of packaging materials. The cost of PP material is lower than that of many other food packaging materials (such as PET, glass, metal, etc.), which can reduce packaging costs for enterprises and reduce the purchase burden on consumers.
Environmental Protection
PP material is a thermoplastic. After being discarded, it can be recycled and reprocessed into other plastic products (such as plastic pallets, recycled plastic bottles, etc.), realizing the recycling of resources. Our products can be naturally degraded in specific environments, reducing long-term pollution to the environment.
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 |
