PLITEK® manufactures one-way degassing valves and vents for a wide range of product packaging applications including coffee, pet food, vitamins, fruits and vegetables, products with yeast, and other products requiring gas and head space gas evacuation from sealed packaging. PLI-VALV® one-way degassing valves and vents enable head-space gases from inside of sealed packaging to escape while providing an effective barrier to environmental oxygen, moisture, and contamination keeping products intact and preserving its quality.  

With billions used worldwide, PLI-VALV® one-way degassing valve technology effectively releases internal gas build-up while sealing-out environmental oxygen, moisture, and contaminants. What’s more, PLI-VALV® vent technology efficiently evacuates air required for packaging and palletizing. 

We design, manufacture, install and service valve applicator systems for customers that want to use our leading-edge degassing technology within their facilities. PLI-VALV® applicator systems are installed on existing or new vertical or horizontal form fill seal equipment. Our applicators can apply from 50 to 300+ valves per minute, making it an efficient degassing solution. In order to truly understand the issues our customers face when packaging their product, we replicate their processes to better understand their unique requirements and challenges.  For instance, we have a small coffee roaster where we over roast green coffee to achieve highest levels of CO2 off-gassing. Coffee is immediately ground and packed into premade bags with a PLI-VALV® one-way degassing valve. Our engineering and quality teams then conduct a series of tests to validate the performance of each valve.
