Our paper bag production line consists of paper tube forming machine(Tuber) and bottom pasting machine(Bottomer). The products-Valve bags are used for a vast number of applications, primarily in the building materials and food industries, to filling goods such as:cement,chemical material, feeds, fertilizers,tea,rice etc. Valve paper Bags:
Bags can be made of 2~4 layers kraft paper or paper with one layer of PE/PP film.2~4 colors printing available in Tuber line.
The bags opening or valve in one corner through which the sack is filled. The valve is made with an inner flap which functions as a self-closing check valve after filling. It is available with a plain valve or with an extended inner sleeve of paper or film.
Different models can produce different kinds of bags,like standard cement bags,chemical/cement bags with bottom strengthen sheet,tea bag with PP Liner to enhanced moisture protection.
