Side folded bags with aroma protection valve

Optimal protection: side lines with aroma protection valve

The side folding bag is characterized by its side wrinkles on the side walls. The folds serve to open the bag when filling to take up a larger volume and to combine them into flat pages if it is empty or filled with less volume. The side folds therefore offer a lot of flexibility and space. Our side lines are equipped with an aroma protection valve and are ideal for finely ground food. They consist of OPP plastic, are food -safe and welded with a seal seam. The aroma protection valve ensures that the food retains their fragrance and taste. We lead our side lines with aroma protection valve in two colors - in classic black or chic gold. They come easily and can be designed as desired. The bags can be welded after filling or closed with a clip. The right clips can be found in our shop under the menu item Accessories.

Aroma protection valve for long -lasting fragrance and taste

Aroma protection valves are integrated directly into the packaging and serve to preserve the aroma of sensitive products such as coffee, tea or spices. The valve works according to the principle of fermentation. If, for example, coffee beans are roasted, gases such as carbon dioxide can be released subsequently, which inflate the bag and increase the pressure inside. This can lead to damage to the packaging. With the aroma protection valve, the gases released can escape from the packaging. At the same time, the valve prevents the penetration of air humidity and oxygen. The valve is designed in such a way that it is airtight when no pressure is exerted on the packaging from the inside. This prevents air from falling into the bag from the outside and the product contaminates.

What specific properties must side lines with aroma protection valve have?

In order to ensure the function of the aroma protection valve and reliably protect the content, the side lines must have certain properties.

  • Airtightness: The side lines must seal airtight to ensure that no air exchange, except through the valve, takes place between the inside and the outer. The side lines of bag shop are welded and thus offer optimal airtightness.
  • Robust construction: The bag should consist of a robust and tear -resistant material to prevent damage during transport or storage. Our bags are stable, tear -resistant OPP side lines.
  • High quality aroma protection valve: The valve itself must be of good quality so that its function is guaranteed.
  • Optimal placement of the valve: The aroma protection valve must be placed in the right place to facilitate the gas exchange.
  • Compatibility with the filling process: Side fold bags must be designed in such a way that they can be easily integrated into the filling process without the valve being damaged.
