Detailed explanation-1: -Polypropylene is a relatively new film in frozen food packaging, but its clarity, strength at low temperatures, and low WVTR make it useful in laminates, and in coating paper or aluminum foil. It is heat-sealable when it is treated with a variety of coatings.

Detailed explanation-2: -According to the US Department of Agriculture, aluminum foil is a great choice for wrapping frozen food since it’s a food-grade material. It’s also light, flexible, and non-toxic, which ensures that your food stays safe while in the container.

Detailed explanation-3: -When it comes to food packaging, polyolefin is your best choice. Polyolefin shrink film is FDA food-safe approved and can also be made kosher. Polyolefin shrink film is perfect for sealing boxed frozen foods such as pies, pizzas, cakes, baked goods, vegetables, fruit, and almost every other type of frozen food.

Detailed explanation-4: -Laminating is the process through which two or more flexible packaging webs are joined together using a bonding agent. The substrates making up the webs may consist of films, papers, or aluminum foils.
