CZVB is a heat sealable, high barrier metalized CPP film.
CZVB film contains the following critical properties:
- Excellent moisture barrier property
- Excellent gas barrier property
- High light barrier property
- Heat sealable on the non metalized side with very high heat seal strength
To ensure protection of the packed food products against environmental conditions and to provide a longer shelf-life, the seal integrity of the pack must be good enough to prevent leakage and/or prevent entry of the air or moisture through the seal areas. The excellent seal integrity of CZVB film not only prevents the micro leakages through the sealed area but also helps the “gas flushing” of the packaging – gas flushing is where the atmosphere within the package is vacuumed entirely. The oxygen is replaced with an inert gas such as Nitrogen (or Carbon Dioxide) that enables fresh and minimally processed packaged food products to maintain visual, textural and nutritional appeal.
The controlled environment (inside the package) enables the food packaging to provide an extended shelf life without requiring the addition of chemical preservatives or stabilizers. The high barrier metalized CPP (CZVB) film has the excellent moisture barrier (0.2 – 0.3g/mtr2/d) and Oxygen barrier (<30cc/mtr2/d) in comparison with the normal metalized CPP film (WVTR: 0.8- 1.0g/mtr2/d & OTR: 100 – 150cc/mtr2/d). CZVB film has the seal strength in the range of 2000g/in – 2400g/in which is almost double of the heat seal strength of the normal CPP film.The laminate produced with CZVB film provides improved functional properties (e.g. high moisture barrier, high oxygen barrier, light barrier, very high seal strength & excellent hot tack) along with crush & puncture resistance and good machine ability, making the laminate the ideal packaging material for snacks (Potato chips) and bakery products (specially croissants) in order to get an extended shelf life. Taghleef Industries in close collaboration with Al Behar Industries successfully completed the qualification of CZVB at Lora Croissant.
