Flexible packaging is a type of packaging made with materials that can easily change shape or form, such as stand-up pouches, resealable bags, and three-sided pouches.
Unlike rigid packaging, flexible packaging includes materials like plastics, paper, and foil that can be folded, bent, or molded to fit the product they are enclosing.
Flexible packaging has emerged as a versatile and eco-friendly solution for a wide range of products, including snacks, household products, skincare, and more.
The Components of Flexible Packaging
While every flexible packaging design is unique and customized to fit your product, they typically contain a few similar components.
Film
Flexible packaging often begins with thin film substrates, which can be made from various materials like polyethylene and polypropylene. These films are highly adaptable and can be customized to meet specific product requirements.
Most flexible packaging includes layers of film. Typically the top layer is the outer layer where your branding is printed. The middle layer provides a barrier against moisture and oxygen. And the inner layer is what comes in contact with your product and needs to be food-grade.
Common films include:
- Polyethylene terephthalate (PET)
- Oriented polypropylene (OPP)
- Nylon (NY)
- metallized PET (MPET)
- Polyethylene (PE)
- Linear Low Density Poly Ethylene
- Ethylene Vinyl Alcohol (EVOH)
- Cosmetic Web
Closures & Seals
Depending on your needs, there are a variety of different closure and seal options to make the product easy to access and use. Zippers, pourable spouts, resealable seals, and other structural components can be integrated into the packaging to enhance user convenience and product preservation.
Printing and Lamination
Flexible packaging is known for its vibrant and detailed graphics. Advanced printing and lamination techniques allow manufacturers to create visually appealing and informative designs on different areas of the packaging. Some designs even allow for printing on all four sides. This makes flexible packaging an excellent choice for branding and marketing purposes.
Barrier Properties
Many flexible packaging materials are designed to provide excellent barrier properties, protecting the product from factors such as moisture, oxygen, and light. This extends the shelf life of products, making it an ideal choice for perishable goods.
Benefits of Flexible Packaging
In today’s competitive market, maximizing convenience and cost-effectiveness while having packaging that offers the protection and customization you need is crucial for any business. Flexible packaging offers all that and more.
Convenience
The flexibility of the packaging makes products easy for both retailers and customers to handle, use, and store.
Because they’re not heavy or rigid like boxes, retailers can fit more of them on shelves and displays. Plus, pouches and sealed bags are easy for consumers to throw in a backpack or take on the go.
Plus, the packaging works with a variety of resealable closures and easy-to-open features that enhance the user experience.
Cost-Effective
Flexible packaging is much smaller than traditional corrugated packaging, meaning it takes up less space and can ship flat, making it cost-efficient in terms of production, transportation, and storage.
Flexible packaging often requires less material and fillers, which saves energy and material costs during the manufacturing process.
Then because it weighs less than transitional packaging materials, you’ll save money on transportation and shipping costs, which are usually based on weight. In addition, you can fit more flexible packaging in one trailer, since it ships flat.
Customization
Manufacturers can tailor flexible packaging to meet the unique needs of their products, ensuring a perfect fit for various industries,
Product Protection Barriers
The barrier properties of flexible packaging are designed to preserve the quality and freshness of different types of products, ensuring they reach consumers in the best possible condition.
Depending on your products, specific requirements, and regulations, flexible packaging can offer:
- Moisture barriers to protect products against humidity and prevent spoilage, mold growth, and product degradation.
- Oxygen barriers that create an oxygen-free environment inside the package to prevent spoilage and flavor degradation.
- Light protection to shield the product from light, preserving the color, flavor, and nutrient content.
- Temperature resistance for products that need to be stored or transported in challenging conditions. This ensures that the product remains intact and safe, even in freezing or high-temperature environments.
- Physical protection ensures the product remains intact and resists punctures, tears, and compression. This is crucial for products that are fragile or have irregular shapes.
- Odor control properties to trap odors within the package. This is particularly important for products with strong scents, like perfumes and chemicals.
By providing these essential barrier properties, flexible packaging ensures that products maintain their quality, taste, appearance, and safety throughout their entire shelf life. This not only benefits consumers by delivering a better product experience but also reduces food waste and product spoilage, contributing to a more sustainable and environmentally responsible approach to packaging.
Sustainability
If you’re looking for a sustainable packaging option, flexible packaging is a great solution. It is designed to do more with less and typically requires fewer raw materials during production compared to rigid packaging options. The reduction in material use conserves valuable resources and minimizes the environmental footprint associated with resource extraction and processing.
Using less plastic or paper in the manufacturing of flexible packaging means fewer trees need to be cut down or less petroleum-based plastic is needed, thereby reducing the overall environmental impact.
Reduced weight means less fuel consumption during shipping, resulting in lower greenhouse gas emissions and a smaller carbon footprint. This makes it a sustainable choice for companies aiming to reduce their carbon emissions.
Plus, many flexible packaging materials are reusable and recyclable, and manufacturers are increasingly using sustainable materials such as bio-based plastics and paper from responsibly managed forests. Ultimately, flexible packaging can help your organization meet sustainability and circular economy goals.
Applications Across Industries
Flexible packaging is incredibly versatile and finds applications in a wide array of industries. A few common industries that benefit from flexible packaging include:
- Food and beverage: Snacks, coffee, condiments, and pet food often come in flexible packaging, providing excellent protection against external factors that cause spoilage or contamination.
- Health & wellness: Medications, medical devices, and hygiene products benefit from flexible packaging’s ability to maintain product integrity and freshness.
- Personal care: Shampoos, lotions, and other toiletries use flexible packaging for their convenience and branding opportunities. Pouches with seals and pour spouts prevent spillage and are easy to use.
- Household products: Detergents, cleaning supplies, and gardening products rely on flexible packaging for user-friendly designs and to prevent cross-contamination with other products.
