PerfoTec Flexfresh Liners
PerfoTec introduces an innovative bulk bag, the PerfoTec Flexfresh Liner. Smart plastic bags that can be used in existing crates and boxes. The main benefit of the new bulk bag is that it saves money for traders. The extended shelf life results in less weight loss and better preservation of the quality. Additionally, it enables cheaper transportation methods and new export opportunities. For the new bulk and transportation packaging the grower and/or trader only needs new measuring equipment based on which PerfoTec can supply the micro-perforated bulk bags.

Fast Respiration Meter
The innovative and patented PerfoTec Fast Respiration Meter is developed and designed to measure the respiration rate of fresh produce within just 4 hours. This enables you to effectively respond to seasonal variations.
It measures oxygen consumption and carbon dioxide production and calculates the respiration rate. This information can be uploaded onto a website to convert the data into a required packaging transmission per package.
The Fast Respiration Meter comes in three sizes: FRM S, FRM L and FRM XL. And is therefore suitable for small, medium and large-scale producers and packers.
The online software that comes along with the Fast Respiration Meter easily calculates the required film permeability also known as the oxygen transmission rate (OTR).
The results from the respiration meter can easily be uploaded onto the website. In combination with the packaging and film specifications the data is converted into the number /size of laser perforations required to extend the shelf life.
Laser Perforation System
The patented Laser Perforation System adapts the film permeability during packing. It is specially developed for integration with vertical or horizontal packaging machines as well as film converting machines. The PerfoTec laser makes very consistent round holes, which is essential for AMAP technology.
Also critical is the robustness of the laser perforation system.
We understand that it is very important for the laser system to be extremely reliable. And that the conditions under which the production takes place can be tough. The PerfoTec system is developed with these conditions in mind and is able to work reliably in wet, cold and dusty environments.
The Laser Perforation System comes in 3 different models: PER30-S, PER100-ST, PER/200/300/400.
- The PER30-S is especially suitable for small and large packers and can be installed on VFFS*-, flowpack- and trayseal machines.
- The PER100-ST is most used by small and large packers and small film converters and can be installed on VFFS-, flowpack and trayseal machines. And at film converters also on small film slitters, film rewinders and bag forming machines.
- The PER200/300/400 is particularly suitable for small and large film converters and can be installed on slitting and rewinding machines.
The PerfoTec laser can make very small holes of down to 55 – 60 micron in diameter. This is achieved by a special Laser Beam Equaliser. With this instrument the very small micro perforations can be made with the highest consistency. This is especially of importance for salads and ready meal salads, because of the low respiration of these products.
Automatic OTR Control
The PerfoTec Laser System has an integrated camera to inspect each hole. For quality control purposes but also to be able to check and control the Oxygen Transmission Rate (OTR) of each pack. If necessary the laser is automatically adjusted ‘on the fly’ to balance out any variation in film thickness.
The camera inspects each hole. The camera is located directly behind the laser perforation head and checks each perforation in the film. The holes are analysed for diameter and shape. If there is a repetition of missing holes, the packaging machine will (can) be stopped automatically. In this way, the system guarantees that all your packages have the same exact required number of perforations.
