Materials of Packaging of Fruit and Vegetables
PS (Polystyrene):
Polystyrene is known for its clarity, rigidity, and excellent thermoforming properties, making it ideal for creating various packaging shapes. It is lightweight and offers good insulation properties, which helps maintain the temperature of packaged fruits and vegetables. Additionally, PS is easy to dye and mold, allowing for a wide range of colors and designs.
PET (Polyethylene Terephthalate):
PET is recognized for its excellent barrier properties against gases and moisture, which is crucial for extending the shelf life of fruits and vegetables. It has a high melting point, ensuring that it can withstand high temperatures without deforming, making it suitable for hot-fill applications. PET is also known for its good mechanical strength and chemical stability, which means it can protect the contents from external factors.
PLA (Polylactic Acid):
PLA is a bio-based and biodegradable material derived from renewable resources like corn starch. It is an environmentally friendly alternative to traditional plastics. PLA has gained popularity for its ability to break down under industrial composting conditions, reducing environmental impact. It offers good transparency and a natural, matte finish, which can be appealing for eco-conscious consumers. PLA is also known for its ease of processing and ability to create clear and detailed packaging, suitable for a variety of fruits and vegetables
