Which materials is better for Plastic Sushi Box?
When it comes to plastic sushi boxes, there are several materials commonly used, each with its own advantages and considerations:
-
Polypropylene (PP): PP is a popular choice for sushi boxes due to its durability, clarity, and heat resistance. It provides good protection for the sushi and is microwave-safe. PP is also recyclable, making it an environmentally friendly option.
-
Polystyrene (PS): PS is lightweight and has good insulation properties, keeping the sushi fresh for a longer time. It offers excellent clarity, allowing the visual appeal of the sushi to shine through. However, PS is not as heat-resistant as PP and may not be suitable for microwave use.
-
PETE (Polyethylene Terephthalate): PETE is a transparent and lightweight material that offers good barrier properties, keeping the sushi fresh and preventing any flavors from transferring. It is also recyclable and widely accepted for recycling.
-
PLA (Polylactic Acid): PLA is a biodegradable and compostable material made from renewable resources such as cornstarch or sugarcane. It is an environmentally friendly option, but it may have slightly lower heat resistance compared to other plastics.
