Lightweight, versatile, and tamper-evident, film packaging offers a format that meets the demands of both consumers and operations while directly enabling more innovative food product development.
As foodservice and retail environments evolve to feature more diverse grab-and-go offerings, film is playing a central role in shaping how fresh products are protected and presented to customers. In this article, we explain why.
Film packaging refers to any flexible plastic material used to seal products during storage, transport, and retail display.
Packaging film has become a widely used solution across countless industries. Its adaptability makes it suitable for everything from pharmaceutical products to electronics. For food products, it is commonly used as a barrier layer that is paired with a rigid container to extend shelf life.
In some packaging designs, film lidding is paired with a rigid lid, but film can also function as a standalone seal without the need for rigid lidding. Some film lids are designed for one-time use, while peel-and-reseal designs use scored or flanged packaging to allow customers to re-seal the container for multiple uses.
A variety of plastics are employed in film packaging. Some of the most widely used materials include:
When it comes to food applications, PET and PP are among the most widely used due to their proven safety, barrier performance, and compliance with regulatory standards.
While most food packaging films offer protection against moisture and contaminants, high barrier films are engineered to provide significantly greater resistance to oxygen, vapor, and light. These specialized materials (often used for vacuum-sealed products, shelf-stable meals, and meats) typically incorporate multiple layers or coatings to extend shelf life and preserve sensitive contents. By contrast, standard barrier films are more commonly used for fresh (often refrigerated) foods with comparatively short target shelf lives, where they offer a balance of clarity and protection.
In conjunction with rigid containers, plastic film offers a number of advantages that make it well-suited for fresh and prepared food packaging.

While the fundamentals of film packaging are well understood, new innovations in material use and packaging design are pushing the market forward, even as broader trends continue to elevate the economic value of film seal packaging.
Layering multiple materials (like PET along with paper or aluminum) can add different levels of protection but risks reducing recyclability. Mono-material designs are being increasingly sought after due to their enhanced ease of recyclability; they can be recycled just like any other material made from recyclable polymers. With the right design, a 100% polymer film layer can provide ample protection for fresh food products.
More health-conscious consumers are expecting brands to deliver greater transparency (both literally and figuratively) into the quality of food products and ingredients. Film seal packaging can deliver. Snack Food & Wholesale Bakery notes that “the growing importance of health and wellness has propelled the use of transparent films and windows. See-through packaging enables consumers to see the quality and freshness of the contents, which underscores the promise of a wholesome, healthy product.”
An increasing focus on sustainable packaging design is driving interest in film seal packaging. In an article on new horizons in produce packaging, ProduceBusiness notes that many grocers are increasing their preference for film-based containers for fresh grab-and-go food because film uses less material than traditional alternatives like clamshell containers. As we explore below, new design innovations have the potential to push these savings even further.
The adaptability of plastic film makes it a natural fit for the expanding range of private label, seasonal, and limited-run offerings in today’s grocery market. Whether used by in-store operations or processors serving multiple retail programs, flexible film enables quick format changes, smaller production runs, and a variety of product configurations without requiring major equipment or packaging overhauls.
New approaches to package geometry are reshaping how film-sealed containers balance form and function. Seal N’ Flip is a great example: by relocating the lidding film to the bottom, it not only lowers plastic use but also puts the product front and center for stronger shelf appeal.
Seal N’ Flip reimagines the standard film-sealed container by flipping the lidding film to the bottom, reducing plastic use by up to 50% and lowering packaging costs by as much as 25% compared to traditional clamshells.
This product-forward format enhances product visibility on the shelf, simplifies merchandising, and supports a wide range of fresh food applications. Built for efficiency and visual impact, Seal N’ Flip reflects how film seal food packaging continues to advance in both form and function.
