1 – Flexible Plastic Films: Plastic films are widely used for pouch packaging due to their versatility, durability, and barrier properties. Common types of plastic films include:

• Polyethylene (PE): PE films are lightweight and have good moisture resistance. They are commonly used for packaging products like snacks, frozen food, and produce.

• Polypropylene (PP): PP films offer excellent clarity and heat resistance. They are commonly used for packaging products like confectionery, snacks, and baked goods.

• Polyethylene terephthalate (PET): PET films have excellent strength, clarity, and gas barrier properties. They are commonly used for packaging products like beverages, sauces, and personal care items.
• Nylon (PA): Nylon films have high puncture resistance and are commonly used in applications where strength and durability are critical, such as packaging meat and cheese.

2 – Aluminum Foil: Aluminum foil is used as a barrier layer in pouches to provide excellent protection against oxygen, light, and moisture. It is commonly used for packaging products that require high barrier properties, such as coffee, snacks, and pharmaceuticals.

3 – Laminated Films: Laminated films are composed of multiple layers of different materials, combining their respective properties. For example, a common structure is a combination of plastic film and aluminum foil, which provides both barrier properties and flexibility. Laminated films are used for various products, including food, beverages, and personal care items.

4 – Paperboard: Paperboard pouches offer a more sustainable and eco-friendly option compared to purely plastic-based pouches. They are commonly used for packaging products like cereals, powders, and dry goods.
