SealCheckDL: total quality assurance for global food manufacturers
Automated seal integrity inspection you can trust
Why SealCheckDL?
As a technology engineering business which specialises in intelligent vision inspection systems, Bytronic understands the risks to manufacturing created by points of failure in a complex and fast-moving environment. These failure modes can be microscopic and undetectable to standard optical inspection cameras. An example is seal integrity on an aluminium foil tray leading to food safety risks and expensive product recalls.
SealCheckDL is a Bytronic Intelligent Inspection Suite product, a multi-layered intelligent automated seal inspection system for manufacturing which analyses every aspect of the production process: from right product right pack to seal integrity inspections and Bill of Materials verification.
Implementing SealCheckDL derisks manufacturing, safeguards product integrity and protects customer trust. A proven and trusted product with leading global manufacturers.

SealCheckDL derisks production and delivers
total quality assurance
- Automated seal inspection at full line speed – every pack checked without slowing throughput
- 100% seal compliance – ensures products are correctly sealed, protecting quality and safety
- Full regulatory confidence – traceable inspection data supports audits and compliance requirements
- Reduced waste and recalls – faulty seals are detected early, cutting costs and reputational risk
- Fast return on investment – typical ROI achieved within 6–12 months through lower defects and higher productivity.
What is SealCheckDL?
SealCheckDL is an advanced industrial vision inspection system designed to verify the integrity of packaging seals in real time at full line speed. It ensures that every pack is correctly sealed, protecting product quality, safety, and compliance across sectors such as food and beverage, pharmaceuticals, and consumer goods.
Its intelligent software uses the latest AI technology and rules-based logic to apply deep learning to machine vision data from high performance vision, thermal or hybrid inspection cameras and sensors, including hyperspectral cameras. The system can detect incomplete, misaligned, or faulty seals at line speed, and trigger immediate quality control interventions for failed products.
SealCheckDL system can be retrofitted as single or multi-modal installation onto multiple lines across sites and is fully compatible with every OEM, software and line partner.
SealCheckDL ensures consistent, high quality, compliant and safe product is delivered at speed.
Improve productivity
Automated seal inspection improves poor seal detection accuracy without impacting speed and flow.
Improve safety
Standards compliant seal integrity inspection protects consumer health, improve shelf life and stops recalls.
Drive quality
Delivers quality assured product at speed to customers. Enhances brand reputation for new product opportunities.
How does SealCheckDL work?
SealCheckDL uses industrial thermal and vision smart cameras and deep learning capabilities to inspect each pack as it moves through the production line. So defects are identified immediately.
- Detection: Cameras capture detailed images of every seal
- Analysis: Deep learning analyses any packaging type from multiple inspection points at a microscope level
- Verification: Faulty packs are flagged or rejected automatically, so only compliant products continue down the line
- Integration: Connects seamlessly with IPC, MES & PLC systems, providing structured inspection data for compliance.
The system is flexible and can be configured for any packaging format, including trays, pouches, cartons, and thermoformed packs.
SealCheckDL for high‑risk food products
Seal integrity is mission‑critical for high‑risk food categories, where even minor seal failures can compromise safety and compliance. SealCheck DL supports manufacturers in meeting rigorous Quality Control Points (QCPs) by delivering automated seal inspection at line speed.
High‑risk food products include:
- Dairy and chilled foods – vulnerable to bacterial growth if seals fail
- Ready‑to‑eat meals and fresh produce – requiring airtight packaging to prevent contamination
- Infant formula and baby food – subject to the strictest safety and regulatory standards
- Meat, poultry, and seafood – where seal integrity is essential to prevent leakage and spoilage.
SealCheckDL ensures the highest standards of product safety, compliance,
and consumer trust for manufacturers.
How does SealCheckDL work in a production environment
SealCheckDL is designed for high‑speed production lines and can be installed as a new system or retrofitted with minimal downtime.
- Scalable deployment: Works across single or multiple lines and can be rolled out globally for consistent quality standards
- Full line speed: Inspections are performed without slowing throughput, protecting productivity
- Audit trail: Every inspection is logged, providing traceable data for compliance and reporting
- User management: Role‑based access ensures secure operation, supported by the Bytronic smart engineering team
- Compatibility: SealCheckDL integrates with OEM hardware to create multi-modular systems with CodeCheck, PackCheckDL and TempComply for complete packaging and product assurance.
The result is end‑to‑end packaging quality control, reduced risk of defective products reaching customers, and measurable ROI through lower waste and fewer recalls.
