For which applications are flat bags suitable?

Flat bags are made of PE film and are individually welded to the size required by our customers. They are a great choice for many flat goods such as foodstuffs or medical technology products. The level of protection that plastic bags provide makes them suitable for a wide range of industries and products. They are also odorless and tasteless, so the packaged goods always maintain their quality.

While our main customers are companies from the food and packaging sectors, other business avenues benefit from the durable Krus flat bags as well, including the electrical and automotive industry, medical technology, and even agriculture.

What types of flat bags does Krus produce?

We manufacture flat bags from approx. 70 mm up to a width of 1350 mm. Our products are available in the following types: knurled, punched, needled, and perforated.

What materials are used in the production of flat bags?

We use the following materials to make our flat bags: LDPELD, COEX, MDPE, HDPE REGRANULATE, OPP, and CPP

  1. LDPE: This is a low-density polyethylene that is tough and ductile even at low temperatures. It does not contain plasticizers or slags.
  2. COEX: With the COEX film, we offer our customers a very versatile composite film that combines the properties of different materials. (e.g., barrier and welding properties)
  3. MDPE: MDPE is a blend of LDPE and HDPE, and is characterized by high impact and drop resistance.
  4. REGRANULATE: LDPE Since 2007, we have been producing regranulate, a recycled thermoplastic material. This helps our company contribute to the protection of our natural environment. Although the material comes from recycling, the film made that way does not lose its quality.

Don’t worry: if you feel overwhelmed by the number of material choices, make sure to get in touch with us. We are confident that together we will find a film with the best possible price-performance ratio for your goods!

Are flat bags also suitable if the goods need to be protected from moisture?

Yes, definitely. In addition to protecting against environmental influences such as toxins and dirt, flat bags made of PE film are also moisture repellent.

How do the individual designs of flat bags differ in detail?

The differences between our flat bag designs are as follows:

  1. Knurled: the knurling is used to make the flat bags more grippy.
  2. Punched: such bags are especially suitable for goods that produce condensation water
  3. Needled: the needled film allows air to escape during packaging, which helps goods such as foodstuffs stay fresh longer
  4. Perforated: the perforation in the film ensures that any moisture inside can escape.

Our flat bags can be supplemented with antistatic, UV-stabilizing, anti-fog, and anti-block agents – depending on the requirements. This prevents the flat bags from becoming electrostatically charged or the packaged goods from being damaged by UV radiation. Anti-fog additives also ensure that the transparency of our flat bags is maintained despite condensation. Anti-blocking agents prevent the flat bags from sticking to each other.

What must be considered when disposing of flat bags made of PE film?

Disposing of flat bags is not a major challenge. You or your customers can dispose of the PE flat bags similar to other packaging materials via the yellow bag and the yellow garbage can.
