Common Failures In Pouch Packaging
Pouches are a go-to for flexibility and convenience, but they can fail in critical ways—from poor seals to punctures and delamination—that hurt performance and brand reputation. Understanding these failure points helps packaging teams design for real-world reliability.
Seal Failures
- Improper Seal Parameters: Inadequate temperature, pressure, or dwell time can lead to seal weakness or gaps.
- Contamination in Seal Area: Oils, powders, or debris interrupt adhesive bonding.
- Technology-Specific Issues: For example, cold-seal adhesives may struggle with migration in warm environments.
Key Tests:
- Seal Strength – ASTM F88/F88M-23: Measures the force needed to peel a seal.
- Dye Penetration – ASTM F1929-23: Reveals micro-channel leaks with colored dye application.
Punctures & Tears
- Thin Films: Save on cost but vulnerable to rough handling.
- Product Content: Granular or sharp-edged items can degrade film integrity.
- Transit Damage: Handling, stacking, or abrasion increases vulnerability.
Tip: For rougher applications, consider reinforced films or nylon layers.
Delamination
- Poor Adhesion Between Layers: Causes separation and weakened barrier performance.
- Environmental Stress: High humidity or heat can undermine lamination.
- Material Mismatch: Some layers simply don’t bond well together.
Tip: Match adhesives to substrate properties and test under realistic conditions.
Barrier Degradation
- OTR and WVTR Drift: EVOH’s oxygen barrier weakens under humidity, while metallized films can develop pinholes over time.
- Inconsistent PCR Film Quality: While desirable for sustainability, PCR variants may introduce variability in barrier integrity.
Tip: Define target OTR and WVTR values and validate using ASTM F1249 (WVTR) and ASTM D3985 (OTR).
Why This Matters
- For food, compromised seals mean spoilage and recalls.
- In pharma, even small leaks can breach sterility and regulatory compliance.
- Pet products can lose freshness and consumer trust fast.
Preventing these failures starts with engineered material selection, precise sealing validation, and in-line quality testing—not guesswork.

Packaging plays a crucial role in marketing a product. The packaging material and design not only protect the product but also influence the customer’s purchasing decision. Roll stock and pouches are two popular types of flexible packaging used widely across various industries. In this blog post, we will dive deeper into roll stock and pouches and compare and contrast them to help you decide which one is the best option for your packaging needs. What is Roll Stock? Roll stock, also known as roll-fed packaging, is a type of flexible packaging material that comes in a roll form. It is commonly made of plastic materials such as polypropylene, polyethylene, and polyester. Roll stock is a popular choice for packaging products such as snacks, pet food, candy or similar products. Roll stock can be customized to meet the specific needs of a product. It can be printed with high-quality graphics, which is great for branding and marketing purposes. Roll stock can also be made in different sizes, thicknesses, and colors to suit different packaging requirements. Roll stock is produced in large rolls and then cut and formed into the final shape by the packaging manufacturer or co-packer. The manufacturing process is cost-effective, making it a good choice for companies looking to save money on packaging costs. Roll stock takes up less storage space than pre-made pouches because it is produced in large rolls. This makes it easier to store and transport. What are Pouches? Pouches, also known as pre-made bags, are another popular type of flexible packaging. Unlike roll stock, pouches are pre-made and come in various sizes, shapes, and styles. They are commonly made of materials such as plastic films, laminates, and aluminum foil. Pouches can be customized with high-quality graphics and designs, making them a popular choice for branding and marketing purposes. They are used to package a wide range of products such as supplements, powders, foods, beverages and personal care items. Pouches are made by sealing the edges of pre-made bags to create a sealed container. This process creates a tight seal that prevents air and moisture from entering the package, providing better product protection than roll stock. However, because pouches are pre-made and come in standard sizes and shapes, they can be more expensive than roll stock. Differences between Roll Stock and Pouches Here are the key differences between roll stock and pouches: Manufacturing Process Roll stock is produced in large rolls and then cut and formed into the final shape by the packaging manufacturer or co-packer. Pouches, on the other hand, are pre-made and formed into the final shape during the manufacturing process. Roll stock require either vertical or horizontal 4-fill seal machine also known as a vertical or horizontal wrapper. Size and Shape Roll stock can be made in any size or shape, depending on the product’s packaging requirements. Pouches, on the other hand, come in standard sizes and shapes. Printing Roll stock offers more flexibility when it comes to printing. The entire surface of the roll stock can be printed with high-quality graphics, while pouches have limited space for printing. Cost Roll stock tends to be more cost-effective than pouches because it is produced in bulk and is customizable. Pouches, on the other hand, are pre-made in stock and come in standard sizes and shapes, custom pouches can be made for specific sizes, making them more expensive. Storage Space Roll stock takes up less storage space than pouches because it is produced in large rolls, while pouches take up more storage space because they are pre-made and cannot be stacked. Product Protection Pouches provide better product protection than roll stock because they are pre-made and have sealed edges that prevent air and moisture from entering the package. Which One Should You Choose? Both roll stock and pouches have their advantages and disadvantages. The choice ultimately depends on the specific needs of your product. Roll stock is a good choice if you need a flexible packaging material that can be customized in terms of size, shape, and printing. It is also cost-effective and takes up less storage space, making it a good choice for companies with limited storage capacity. Roll stock is ideal for products that don’t require a specific shape or size and don’t need the extra protection provided by a pre-made pouch. Pouches, on the other hand, provide better product protection and are a good choice for products that are sensitive to air and moisture. They are also a good choice for products that require a specific size or shape. Pouches are an excellent option for products that need to stand out on shelves and grab the attention of customers due to their customizable printing options. When deciding which packaging material to use, consider factors such as cost, size, shape, printing, and product protection.

The flexible packaging industry is experiencing a significant evolution as it leans into more sustainable practices. Amid growing environmental concerns, there’s a strong movement within the sector towards developing innovative, eco-friendly packaging solutions. This blog will delve into the most recent sustainable trends impacting the flexible packaging sector, pointing to a future where sustainability and innovation walk hand in hand. Adoption of Biodegradable and Compostable Materials Advancements in Recyclable Packaging Increased Use of Post-Consumer Recycled (PCR) Content Reduction in Packaging Sizes and Weights Innovation in Barrier Materials Investing in Sustainability Education and Transparency Adoption of Biodegradable and Compostable Materials As the world gradually moves away from single-use plastics, one trend that has taken center stage is the use of biodegradable and compostable materials in packaging. These materials are designed to break down naturally in the environment, minimizing their long-term impact on the ecosystem. For instance, some companies are turning to materials like Polyhydroxyalkanoates (PHA), which are fully biodegradable polymers derived from renewable resources. The aim is to make packaging that doesn’t just look good and protect the product, but also contributes positively to the planet. Advancements in Recyclable Packaging Recyclable materials offer another route towards more sustainable packaging. As recycling technologies improve, we are seeing a rise in the use of mono-material packaging — packaging composed of a single type of material, such as all-paper or all-polyethylene structures. This is a game-changer in the recycling process as it eliminates the need for separation, significantly simplifying the recycling process and ensuring that more waste is effectively recycled. Increased Use of Post-Consumer Recycled (PCR) Content Another trend making waves in the flexible packaging sector is the increased use of Post-Consumer Recycled (PCR) content. This involves using materials that have been previously used by consumers and then recycled. Using PCR content helps to lower the demand for new material production, reducing the overall environmental footprint of the packaging. Many companies are setting ambitious goals to incorporate a certain percentage of PCR content into their packaging within the coming years. Reduction in Packaging Sizes and Weights The drive towards sustainability is also encouraging brands to rethink the size and weight of their packaging. By reducing these aspects, companies can decrease the amount of raw material required in the packaging production process, leading to substantial environmental benefits. Furthermore, lighter packaging results in lower transportation emissions, another significant advantage in terms of reducing the carbon footprint. Innovation in Barrier Materials Traditionally, many flexible packaging options have relied on multi-layer structures to provide adequate barrier properties, protecting the contents from moisture, oxygen, and other damaging elements. However, these multi-layer formats can be difficult to recycle. As a response, the industry is innovating to develop high-performing, recyclable barrier materials. These new structures aim to maintain the same high level of protection for the packaged goods while also being easier to recycle, striking a balance between product protection and environmental responsibility. Investing in Sustainability Education and Transparency Many companies in the flexible packaging industry are investing in educating consumers about their sustainable efforts. They are providing information on their packaging about the materials used and how to recycle the packaging correctly. The idea is to involve consumers in the sustainability journey, allowing them to make informed decisions about the products they purchase. Conclusion: Flexible Packaging and Sustainable Trends With these sustainable trends, the future of the flexible packaging industry looks promising. While there are still challenges to overcome, significant strides are being made towards a more sustainable packaging landscape. As technology continues to advance and more innovative solutions are developed, it’s clear that sustainability is more than just a buzzword — it’s a commitment to our planet and future generations. So, in 2024, we can expect these trends to continue driving the flexible packaging industry toward a more sustainable and environmentally responsible future.
