Minimizing Recalls with Seal Inspection Using Vision AI for FMCG Packaging
Every year, thousands of FMCG items are recalled due to packaging seal failures, which are often caused by tiny defects that escape traditional inspection methods. Sealed integrity directly affects product safety, shelf life, and consumer trust, whether in packaged food, beverages, pharmaceuticals, or personal care items. Even a minor, nearly invisible defect in packaging seals can expose contents to contamination, spoilage, or tampering, leading to costly recalls, regulatory penalties, and brand damage.
A clear example is the Jarritos Coconut Water recall, where seal defects raised contamination concerns. Over 2 million cans across 29 states were affected, prompting an urgent consumer advisory to halt consumption.
Traditional manual inspection methods rely heavily on human judgment, which introduces inconsistency, increases costs, and limits scalability. As FMCG manufacturers face growing demand for secure and reliably sealed packaging, it’s clear that manual inspections alone are not sufficient.
This blog explores how seal inspection using Vision AI for FMCG packaging helps manufacturers proactively detect packaging seal defects, reducing the risk of costly product recalls and protecting brand reputation.

Understanding Packaging in FMCG Distribution
Packaging in product distribution is categorized into three levels, each serving a distinct role in efficiently preserving, protecting, and distributing products.
- Primary packaging directly contacts the product, ensuring containment, protection, and consumer appeal. Examples include a cereal pouch or a beverage bottle.
- Secondary packaging groups multiple primary packages into stock-keeping units (SKUs), facilitating handling and providing additional protection. An example is a corrugated box holding multiple cereal boxes.
- Tertiary or transit packaging consolidates SKUs into bulk units for efficient transportation. A stretch-wrapped pallet of secondary packages ensures safe and easy handling from production to the point of sale.
These packaging levels streamline logistics, enhance product safety, and support efficient distribution.
Packaging in FMCG is More Than Just a Container
Different products require different packaging solutions, and each format plays a role in preserving quality, ensuring usability, and making the product stand out on the shelf .
Pouches have become a go-to option for brands looking for lightweight, flexible packaging. Often made from plastic films, they are easy to store, carry, and reseal, making them ideal for snacks, sauces, and personal care items. Bottles, whether glass or plastic, provide durability and product visibility. Glass bottles carry a more premium image, while plastic bottles offer a practical, shatter-resistant alternative.
Cartons made from paperboard are essential for grouping multiple product units and enhancing retail presentation. Corrugated cardboard boxes provide structural integrity and cushioning for bulk shipments and fragile items. Plastic tubs offer a practical solution for products that need easy access and are ideal for spreads, butter, and cream cheese. Cans, typically made of metal, block light, oxygen, and moisture, making them the top choice for carbonated drinks and canned foods. Blister packaging ensures security and clear product visibility for pills, batteries, and small electronics.
How Do Seal Defects in Packages Occur?
Seal defects in packaging can arise from various factors, each of which can compromise the integrity of the package. Understanding these causes is key to maintaining quality and ensuring a secure seal.
Common causes of seal defects include:
- Product Residue Contamination: Liquids, powders, or grease in the sealing area prevent packaging materials from bonding correctly.
- Improper Sealing Temperature: Too low temperatures result in insufficient bonding, while excessive heat damages materials, making them brittle or weak.
- Incorrect Sealing Pressure: Insufficient pressure leads to incomplete seals, while excessive pressure can distort packaging materials.
- Equipment Issues: Misaligned or worn sealing jaws create uneven seals, increasing leakage risk.
- Material Quality Variations: Inconsistent thickness or poor adhesion properties in packaging materials make achieving strong seals difficult.
- Environmental Contaminants: Dust, moisture, and airborne particles interfere with sealing, especially in high-speed production.
- Insufficient Cooling Time: Inadequate setting time after sealing can compromise bonds when packages are handled or moved.
The Impact of Compromised Seals
Compromised seals in FMCG packaging lead to serious consequences across safety, business, operations, and market position. Even minor defects can cause contamination, regulatory violations, and health risks, resulting in penalties and restricted distribution. Recalls incur significant costs and damage brand reputation and consumer trust. Operationally, manufacturers face increased waste, supply chain disruptions, and rising quality control expenses. In the market, seal failures can push consumers toward more reliable alternatives, weakening a company’s competitive position.
Seal Integrity Testing with Vision AI for FMCG Packaging
High-resolution cameras and Vision AI systems capture detailed images of seals and analyze them with Deep Learning models. These models, trained on diverse datasets, identify real-time inconsistencies, defects, or potential contamination. Image preprocessing techniques such as noise reduction, contrast adjustments, and geometric corrections refine the visual data before analysis to enhance accuracy.
Convolutional Neural Networks (CNNs) then classify each seal based on predefined quality criteria, determining whether it meets production standards. Once the analysis is complete, results are instantly communicated to a Programmable Logic Controller (PLC), which makes programming decisions. Approved seals continue through the production line, while defective ones are immediately rejected.
All inspection data is stored in a database, providing traceability and valuable insights for process optimization. A real-time dashboard allows operators to monitor key metrics, including the number of seals inspected, rejection rates, and critical alerts, enabling swift intervention when necessary.
