PP/EVOH/PP or PE food packaging is a type of packaging that uses a multilayer film structure to provide superior barrier properties. The multilayer structure typically consists of a layer of PP (polypropylene), a layer of EVOH (ethylene vinyl alcohol), and another layer of PP (polypropylene).
The PP layers provide strength and stiffness, while the EVOH layer provides a gas barrier, which helps to extend the shelf life of food products. The PE layer on the outside of the film provides a barrier against water and oil.
PP/EVOH/PP or PE food packaging is used for a variety of food products, including fresh produce, meat, poultry, seafood, and dairy products. It is also used for non-food products, such as cosmetics and toiletries.
The main advantage of PP/EVOH/PP or PE food packaging is its ability to extend the shelf life of food products. This is due to the EVOH layer, which provides a gas barrier that helps to prevent food from spoiling.
Another advantage of PP/EVOH/PP or PE food packaging is its ability to maintain the quality of food products. This is due to the PP layers, which provide strength and stiffness, and the PE layer, which provides flexibility and toughness.
PP/EVOH/PP or PE food packaging is also a sustainable option. This is because it is made from renewable resources, such as PP and PE.
Overall, PP/EVOH/PP or PE food packaging is a versatile and sustainable option for packaging food products. It offers a number of advantages, including an extended shelf life, the ability to maintain the quality of food products, and the use of renewable resources.
Here are some of the benefits of using PP/EVOH/PP or PE food packaging:
- Increased shelf life: The EVOH layer in PP/EVOH/PP or PE food packaging provides a gas barrier that helps to prevent food from spoiling. This can lead to an increase in shelf life of up to 50%.
- Improved quality: The PP layers in PP/EVOH/PP or PE food packaging provide strength and stiffness, while the PE layer provides flexibility and toughness. This helps to maintain the quality of food products, even when they are exposed to rough handling or extreme temperatures.
- Reduced waste: PP/EVOH/PP or PE food packaging is a sustainable option because it is made from renewable resources, such as PP and PE. This helps to reduce the amount of waste that is produced each year.
- Increased safety: PP/EVOH/PP or PE food packaging is a safe option because it is free from harmful chemicals and toxins. This makes it a good choice for packaging food products that are intended for consumption by children or pregnant women.
Here are some of the challenges of using PP/EVOH/PP or PE food packaging:
- Cost: PP/EVOH/PP or PE food packaging is more expensive than other types of packaging, such as PP or PE.
- Availability: PP/EVOH/PP or PE food packaging is not as widely available as other types of packaging, such as PP or PE.
- Complexity: PP/EVOH/PP or PE food packaging is more complex to manufacture than other types of packaging, such as PP or PE.
- Environmental impact: The production of PP/EVOH/PP or PE food packaging can have a negative environmental impact, as it requires the use of fossil fuels.
Overall, PP/EVOH/PP or PE food packaging is a versatile, sustainable, and safe option for packaging food products. It offers a number of benefits, including an increased shelf life, improved quality, reduced waste, and increased safety. However, it is also more expensive, less available, and more complex to manufacture than other types of packaging.
