Flexible packaging refers to any packaging material that you can bend and manipulate to a desired shape. A good example is a skincare sample that you get in sachets when you shop from makeup retailers. In contrast, rigid packaging materials cannot be changed after they are formed.
Flexible packaging has found many use cases in a wide range of industries, including but not limited to food and beverage and personal care. Below, we discuss flexible packaging in detail.
What is Flexible Packaging
Any packaging that is made of materials that can be easily deformed or changed into a different shape is called flexible packaging. It could be made of materials like paper, foil, film, and plastic. These materials are then printed on and laminated together to form a pouch, bag, or wrapping.
Examples of flexible packaging include stand-up pouches, flat pouches, bags with zippers, shrink wrap, and more. The main advantage of this versatile packaging is its ability to conform to the product’s shape while still providing protection and preserving freshness.
It is also lightweight, cost-effective, and offers various design options for branding and product information. Like other packaging types, flexible packaging may also be made of recyclable materials, making it an environmentally sustainable choice.
Some key characteristics of flexible packaging are as follows:
- Barrier Properties: The materials used in flexible packaging have excellent barrier properties, which means they can safeguard the contents from external factors like moisture, oxygen, contaminants, and light.
- Versatility: Since flexible packaging can be easily manipulated and customized, it provides a variety of usage options for both product manufacturers and consumers.
- Durability: Just because it’s not rigid doesn’t mean flexible packaging is not sturdy. It can withstand various transportation and handling conditions without compromising the product’s integrity or safety.
More importantly, flexible packaging also requires less material, resulting in less waste and a smaller carbon footprint. It also minimizes the use of secondary packaging, which lowers the overall packaging volume and weight.
Flexible Packaging Materials
Some common materials used in making flexible packaging are foil, plastic film, paper, and laminated combinations of these materials. Each material has its unique properties and is suitable for different types of products.
Depending on the use case, the material may be used alone or combined with other materials to achieve the desired barrier and aesthetic properties.
For example, pharmaceutical industries may require a combination of foil and plastic film to create airtight and light-resistant packaging for medicines. In contrast, food companies opt for paper or plastic films for their products.
Paper is usually a popular choice for dry food products such as chips, while plastic films are commonly used for liquids or semi-liquid items like sauces and dressings. Retail products such as cosmetics and personal care items often use a combination of plastic films for the main packaging and paper for the external label or design.
The choice of material ultimately depends on the product’s requirements. How protected you want the item to be also determines the type of flexible packaging you use.
In recent years, sustainable product packaging has become a prominent trend in both developed and developing countries. Consumers are even willing to pay more for it. In flexible packaging, sustainable options like biodegradable plastic films and compostable materials are gaining popularity.
Types of Flexible Packaging
Flexible packaging is available in many types. Here are some common types that are used in various industries:
- Pouches: These are the most common type of flexible packaging and are usually made of plastic films. You would have seen them in various sizes and shapes at your local grocery store, holding products like snacks, beverages, and frozen foods.
- Bags: Custom paper bags are widely used packaging for retail products, especially in the fashion and luxury industry. They are also used as gift bags during special occasions. Plastic bags are still widely used in grocery stores, but there has been a growing shift towards more sustainable options like biodegradable bags.
- Wraps and Films: These are used for primary packaging, which is the layer that directly touches the product. They are commonly seen in food products like cheese and meats.
- Sachets: A ketchup sachet or a single-use shampoo packet are examples of this type of flexible packaging. They are convenient for consumers and also maintain appropriate portion control, reducing food waste.
- Form-Fill Seal: It is used for liquids and powders like detergents and juices. The packaging material is formed, filled with the product, and sealed in one continuous process.
- Tubes: Packaging for products like toothpaste, creams, and gels often come in a tube form. They are lightweight, easy to use, and can be manufactured with sustainable materials like biodegradable plastic.
Flexible Packaging vs. Rigid Packaging
While both rigid and flexible packaging are used in retail and other applications, their distinct features make them suitable for different products. The table below compares the two in different aspects.
| Aspect | Flexible Packaging | Rigid Packaging |
|---|---|---|
| Cost | Generally more cost-effective due to lower material use | Higher production costs due to heavier materials |
| Transportation | Reduces transportation costs due to lightweight design | Increased shipping expenses due to bulkiness |
| Versatility | Highly adaptable to various product sizes and shapes | Limited flexibility in design and shape |
| Environmental Impact | More sustainable with recyclable, compostable, and lightweight options | Often less eco-friendly due to higher material use |
| Performance | Excellent barrier properties for preserving freshness and protecting products from contaminants | Extremely durable and robust, ideal for heavy or fragile products. |
| Customization | Offers a wide range of customization options (design, closures, etc.) | More suitable for standardized products |
Benefits of Flexible Packaging
Compared to its rigid alternatives, flexible packaging has a lot of benefits. To start, it is quite cost-effective. When you use rigid packaging products, you’re wasting a lot of material, especially when you’re using complex shapes. With flexible packaging, there’s relatively little waste, and the packages are easier to transport.
Besides lower packaging costs, you can also enjoy higher customization. There are many ways to create colorful and engaging designs on flexible packaging. At the same time, you can incorporate different features like zippers, spouts, and windows to make it stand out.
Flexible packaging is also lightweight, which means lower transportation costs. During transportation, fuel consumption will be relatively less if your product has flexible packaging compared to rigid ones. Also, there’ll be less CO2 emissions.
Compared to rigid packaging, the barrier properties of flexible packages are incredibly high. The packaging keeps out moisture and oxygen, keeping the product fresh for a long time. Since there are no seams or joints, it’s difficult for any external elements to break in.
In terms of waste management, flexible packaging is more favorable compared to rigid alternatives. It takes up less space in landfills due to its compact and lightweight nature, reducing the overall environmental impact.
As for retail spaces, such as supermarkets and grocery stores, flexible packaging offers more efficient use of shelf space. Its adaptability to different shapes and sizes allows for better organization and display of products, attracting more consumers.
Plus, it enhances product and shelf life. Its barrier properties keep the products fresh for longer. There’s also less risk of spoilage or waste. It also means lower product loss for manufacturers and retailers, leading to increased profits.
The versatility of flexible packaging extends to a wide range of industries, from pharmaceuticals and cosmetics to food and beverage. Its ability to cater to the diverse needs of different industrial sectors makes it a popular choice for businesses of all sizes.
