BOPP film is a very important soft packaging material. BOPP film is colorless, odorless, tasteless and non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. BOPP thin film surface can be low, coated or before printing needs to conduct corona treatment. However, after the BOPP film has been treated with corona, it has good printing adaptability, and can be used in color printing to obtain a fine appearance effect. Therefore, it is often used as the coating material for composite films. BOPP film is also deficient, such as easy to accumulate static electricity, no heat sealing.

The BOPP film is easy to generate static electricity on the high-speed line, and static remover is installed. For BOPP film can be heat sealed, can be coated after BOPP film surface corona treatment can heat sealing liquid resin adhesive, such as PVDC latex, EVA latex, etc., can also be solvent coating glue, also can adopt the method of extrusion coating or co-extrusion composite heat sealing BOPP film production. The film is widely used in the packaging of bread, clothing, shoes and socks, as well as the cover of cigarettes and books. BOPP film cause tearing strength improved after stretching, but secondary tear strength is low, therefore, two ends can’t leave any incision of BOPP film, otherwise the BOPP film easy to tear off when printing, composite. BOPP coated adhesive can produce sealing tape, which is a large market for BOPP.

We have a production process for Square Bottom Plastic Food Bags.

(2) tension control system.

Paper or film in the rolling process before printing, multicolor printing process or after printing paper in the process of all need to keep a certain tension, tension is too large to produce longitudinal wrinkles, tension is too small to produce transverse furrow, anyhow tension fluctuation influence the accuracy of overprint.

(3) horizontal deviation adjustment device of paper tape.

In order to ensure that the paper tape enters the printing part or the horizontal rule in the same time, it is necessary to have the adjustment device.
