Vacuum Bags – Tehran Times

Vacuum bags have become very popular in industrial and household packaging, which makes the vacuum bag would be in a particular place.

The Vacuum bags have been used in different applications: food preservation, compression of cloths, protection of electronic devices, etc. Several sizes, thicknesses and types are available to accommodate a variety of products. Their mechanism is simple: suck the air inside the Bag and ensure that the Bag is a barrier to the diffusion of air.

Three factors are needed to determine the quality of vacuum bags:

• Bag materials

• Layer thickness

• Ribbed profile (embossed)


The material composition of the bags is a critical factor in ensuring that the bags will be waterproof and sealed to a high standard to maintain the vacuum. The best way to make a vacuum bag is to use multi-layer film as it offers various specifications. The inner layer is in direct contact with food or sensitive products, so there is no reaction between the bags and the stored products. The best material for this purpose is polyethylene (PE), which provides quality sealing. The polyamide in the outer layer provides a barrier film which makes a suitable vacuum bag. The bags on the market have the appropriate polyamide thickness and protect the stored products from oxidation or other damage due to air diffusion. 20 to 30 µm of polyamide on the outer layer constitute a barrier layer to the entry of air.


Food vacuum bags should be thick enough as they also protect products from external mechanical damage. The food vacuum bags available have a smooth layer with a thickness of 100 micrometers and a ribbed layer with a thickness of 130 micrometers.

Ribbed profile (embossed)

The final factor that distinguishes premium vacuum bags from inferior bags is the shape and height of the relief profile (channel layer). Both are important for effective vacuuming (removal of air from the bag). When you start sucking the air out of the bag with two smooth layers, the layers stick together even before all the air is removed, and the food would not be stored properly. The unique shape of the channels in the raised profile ensures adequate air circulation during vacuum packaging. Raised profile height provides quality vacuum storage.

Karya Polymer Vacuum bags (with zipper and side valve) or compression bags have become very popular in recent years as more and more people have started compressing clothes and fabrics to save space. The bags reduce packaging volume by up to four times. The possibility of easy air release with an automatic capless valve has made using these bags very simple. Vacuum packaging reduces atmospheric oxygen and limits the growth of aerobic bacteria or fungi. Oxygen removal can often go a long way in extending product life.

You can compress, store, and organize your blankets, pillows, cushions, clothes, and other bulky items with any vacuum. The Karya Polymer bag is optimal for protecting documents, paper supplies and other moisture-sensitive items. It consists of a five-layer barrier film. These bags preserve the quality of paper products by preventing the ingress of moisture.

In most homes, storage space is premium, so it makes sense to conserve as much space as possible. Space Saver Vacuum bags are a great way to store items without taking up too much storage space.

The best vacuum bag should be strong, have tight seals to keep items compressed, and be the right size for the things you want to store.


Reduce the bulk of clothes, blankets and pillows up to 4 times

·Improve layout and increase free space for closet and luggage.
