Types of flexible packaging
There are many types of flexible food packaging. They are mainly made of a combination of plastic, aluminum foil, film, and other materials. Common types include Flexible Films: Pouches, Protective Packaging, etc.

There are many types of flexible films. There are stretch film, LDPE Bags, BOPP film, aluminum foil packaging, and so on.
Stretch film can be used to wrap pallets and products tightly together .
BOPP film is ideal for food packaging. Candy, snacks, and chips can be wrapped in it. It works better and costs less. And it is FDA approved and can be used in direct contact with food. It will not produce harmful substances.
Aluminum foil has very good barrier properties, which can well isolate air, light, moisture, odor, and bacteria. It ensures the safety of the products.
Pouches:
There are three main types of pouches: sand-up pouches, lay flat pouches, and roll stock.
Sand-up pouches are one of the most popular types of flexible packaging. It has a very unique design. It can easily stand on top of the shelf.
Sand-up pouches have plenty of space to display product information and brand information. It can be very good to attract users and consumers’ eyes. Wide range of applications. Snacks, personal care products, and pet food all have applications.

A roll is a bag that has not been made into a pouch. It is a continuous roll of printed film. It has a barrier film and a structural film on it. It can be used in a variety of places. For example, candy wrappers. The use of rolls allows for good adaptation to the size and shape of the product.
Protective Packaging:
There are three main types: foam, packaging tapes, and Bubble Wrap.
Foam can be used to package high-end items. The Liner is cut precisely according to the shape of the product. It fits the product well.
Packaging tapes are mainly used for sealing package.

Polyethylene PE
Polyethylene is widely used in the flexible packaging market and is a common type of plastic. It is generally transparent. There are three types: high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene(LLDPE). Polyethylene has strong Chemical Resistance. It can withstand corrosion from acid and alkali solutions. It offers excellent moisture resistance, protecting against humidity. LDPE has higher strength.
Polyethylene Terephthalate (PET)
PET is a resin known for its superior strength and durability. Its high tensile strength and impact resistance make it ideal for products requiring enhanced protection. Being impermeable and waterproof, it is commonly used for packaging beverage bottles. PET maintains stable performance up to 180°C. It is non-toxic and odorless. Which can safely contain hot foods within its temperature tolerance.
Polypropylene (PP)
Polypropylene is a thermoplastic with properties similar to polyethylene. It has a high melting point of 167°C. Its strong chemical stability resists corrosion from most chemical solutions. Polypropylene is typically semi-transparent. It is lightweight and sturdy but has poor oxygen barrier properties. Commonly used for beverage packaging, laundry baskets, and buckets.
Sustainable Materials
Under environmental considerations, optimized materials are also available for flexible packaging films. These include recycled packaging and compostable materials. Using these materials helps reduce environmental pollution associated with manufacturing. They are commonly used for cling film and shopping bags.
Aluminum Foil
Aluminum foil is manufactured from flattened aluminum. In flexible packaging, it is primarily used for food and cosmetic packaging. Aluminum foil can serve as a sealing material over beverage bottle openings. Providing a freshness seal and preventing flavor transfer. It can also be wrapped around cosmetic surfaces to offer oxidation protection and enhance aesthetics.
