Block bottom bags with sealed bottoms are made of 40 micron thick OPP film, transparent (unprinted). Thanks to the sealed bottom, the bags are 100% closed, making them impermeable. The sealed bottom is stronger than a glued bottom. The bags are without pre-printed weight.
Because the bags are made entirely of OPP, they are very suitable for packaging greasy or oil-containing foods, such as roasted nuts.
The bags can be closed with a clip or label, which you can also find in our offer. Since the bags are made entirely of OPP, it is no problem to use sealing as a method of closing the bags.
The abbreviation PP stands for polypropylene. Polypropylene was developed in the 1950s and is resistant to chemical solvents, alkaline substances, acids, and bacterial growth. Technically, OPP-PP film is stretched in the longitudinal direction.
All our bags are made from the best materials (BPA-free) and are suitable for food packaging in accordance with EU regulations and safety standards (EG 1935/2004, EG 2002/72, and EG 10/2011).
Bottom-sealed bags are:
- unmarked weight
- food safe
- stable (when filled)
- odorless and tasteless
