Inside the Factory: How Batch Coding, Sealing & QC Keep Products Safe

Aug 26, 2025Darren Fleury

When it comes to chemical manufacturing, the process doesn’t stop once the liquid is mixed. The final steps — batch coding, sealing, and quality control (QC) — are what ensure your product is not only ready for shelves but also safe, compliant, and trusted by customers.

At Innovation Chem, these finishing touches are built into every run we complete. Here’s why they matter and how we handle them in-house.


Batch Coding: Traceability from Start to Finish

Every product leaving our factory carries a unique batch code linked directly to its production record. This allows us (and you) to:

  • Trace exactly when and where the product was made.
  • Match the batch to raw material records and QC test data.
  • Investigate or recall with precision if an issue ever arises.

Batch codes are printed automatically on the line using high-speed inkjet coders. This isn’t just compliance — it’s peace of mind for both brand owners and end-users.


Induction Seals & Tamper Protection

After filling and capping, products are sealed using induction heat technology. This creates an airtight bond under the cap, preventing leaks in transit and providing visible tamper protection.

  • Helps prevent leaks and courier damage during shipping.
  • Supports shelf life by limiting oxygen and moisture ingress.
  • Gives customers confidence the product hasn’t been opened.

Where appropriate, we add secondary protections such as shrink bands or trigger locks, so the packaging is truly retail-ready.


Quality Control: Every Batch Checked, Every Time

QC is more than a tick-box. For each batch we manufacture, we carry out:

  • Laboratory checks: pH, viscosity, appearance and odour against specification.
  • On-line checks: fill weight verification, torque checks, seal integrity and label accuracy.
  • Documentation: full batch records, material traceability and sign-offs.
  • Retains: we hold a reference sample from every production run for future verification.

This ensures every bottle leaving our site meets the same standard — consistently.


What It Means for Your Brand

  • Safety: tamper-evidence and leak prevention protect end users.
  • Reputation: consistent product quality builds trust and repeat purchase.
  • Scalability: robust coding and documentation support retail, export and audits.
