Frequently Asked Questions

Can these pouches be utilized for answer applications?

Yes. We use high-spec materials like RCPP with specialized adhesives. These can withstand temperatures up to 121°C. Your retorted products remain shelf-stable throughout processing.

What causes pouches to curl?

Curling typically results from improper tension control during lamination. Substrates with different thermal expansion coefficients require precise tension management. Our experienced team avoids this issue through strict process control.

Are these pouches recyclable?

Traditional multi-layer pouches present recycling challenges. However, we now offer Mono-material (Mono-PE) versions. These meet industry 'Recycle Ready' standards and support your sustainability goals.

Why might seals fail?

Seal failure usually happens due to contamination in the seal area. Product powder or liquids can interfere with the bond. Incorrect calibration of heat, dwell time, and pressure on the sealing jaw also causes issues. We provide detailed sealing parameters to ensure seal integrity.

We offer flexible MOQ options. This makes our packaging accessible for new companies and small batch production. Contact us to discuss your specific needs.

Do you offer samples before bulk orders?
