CPET trays generally have good resistance to grease and oils. This resistance to grease is one of the factors that makes CPET a popular choice for packaging a variety of food items, especially those that contain oils or fats. Here are some key points regarding CPET's grease resistance:
Non-Porous Material: CPET is a non-porous material, which means that it does not have tiny openings or pores that can absorb liquids, including grease. This non-porous nature helps prevent the penetration of oils and fats into the tray's structure.
Oil and Fat Resistance: CPET trays are designed to resist the effects of oils and fats commonly found in foods. They do not react with or absorb these substances, ensuring that the packaging remains intact and does not become weakened or compromised.
Food Compatibility: CPET trays are suitable for packaging a wide range of food items that contain oils and fats, such as fried foods, baked goods with butter or oils, roasted meats, and other similar products. The trays help maintain the quality and appearance of the food by preventing grease from seeping through.
Ease of Cleaning: The grease-resistant properties of CPET trays also make them relatively easy to clean, especially when compared to porous materials that can absorb grease and become difficult to clean thoroughly.
CPET trays are generally grease-resistant, the specific performance may vary depending on the formulation and any additional coatings or barrier layers applied to the trays. Manufacturers often conduct compatibility testing with specific food products to ensure that their packaging materials meet regulatory and safety standards and maintain their integrity when exposed to greasy or oily foods.
