The right packaging film can ensure that your products are shipped in great condition, stay fresh and healthy during transit, and save you money. But if you’re unfamiliar with the different types of packaging films available, it can be hard to determine which one is right for your business. In this article, we’ll explore the most popular types of packaging film and compare their raw materials, similarities, differences, and applications so you can choose the best option for your needs.

A plastic film is a continuous sheet of thin polymer material used to wrap or seal items. These plastic membranes are often coated with a printing ink to make them more attractive or functional. Films are used for a wide variety of purposes, including protecting items from moisture and other contaminants, providing rigidity and retaining heat, and creating a barrier to oxygen and gas.

Typically made of polyethylene (PE), flexible packaging films can be divided into a number of categories based on their material composition and application. High-density PE (HDPE) and low-density PE (LDPE) are the most common materials used to make flexible packaging, but other options include polypropylene, polyester, and EVOH. In addition to determining the type of film needed, factors such as thickness, printability, and barrier properties are important when selecting the right film for a specific product.

Some of the most popular uses for packaging film are food and beverage packaging, medical and pharmaceuticals, and industrial and consumer goods. The global market for flexible packaging films is growing rapidly due to a rise in e-commerce sales, which requires more packaged goods. High-quality, flexible films are also an excellent way to protect goods from external contaminants and keep them fresh.

Other benefits of flexible packaging include increased durability, ease of handling, and better storage space. Some flexible films are even resistant to puncturing and tearing, which makes them ideal for shipping heavy or fragile goods. Foil packaging is also an excellent choice for many industries because it provides a solid barrier to external contamination and odors, keeping products safe and prolonging their shelf life.

Lastly, some flexible packaging films are designed to improve machine performance by offering more rigidity and greater heat resistance, allowing them to be used in microwave and hot-filled foods. These films often include layers of HDPE, LDPE, or LLDPE combined with an aroma barrier.

As sustainability becomes increasingly important for CPG businesses, it’s essential to consider the environmental impact of your packaging choices. Fortunately, many of today’s polyolefin and flexible food packaging films are recyclable. These films also do not release harmful vapors during the heat-sealing process and are FDA-approved to be food-safe. Some companies are even experimenting with biodegradable or compostable alternatives to plastics for flexible packaging.
