Superslim 122mm Size Cigarette BOPP Film Static-Free

Due to the molecular orientation, the crystallinity is improved, the tensile strength, impact strength, rigidity, toughness, moisture resistance and transparency are all improved, and the cold resistance of the film is also improved.
Good gas barrier and moisture resistance
High transparency, good gloss, good printability
It is non-toxic, odorless and tasteless, and can be directly used in contact with food and medicine.

Biaxially oriented polypropylene (BOPP) film is film stretched in both machine and transverse directions, producing molecular chain orientation in two directions. BOPP film is produced by a tubular process, in which a tubular bubble is inflated, or a tenter frame process, in which a thick extruded sheet is heated to its softening point (not to the melting point) and is mechanically stretched by 300–400%.

Oriented films can be used as heat-shrinkable films in shrink-wrap applications or can be heat set to provide dimensional stability. Heat sealing is difficult in BOPP films, but can be made easier by either coating the film after processing with a heat-sealable material (such as polyvinylidene chloride) or by co-extrusion with one or more copolymers before processing to produce layers of film. Copolymers used in sealing layers must have high gloss and clarity and should have low sealing temperatures to prevent distortion of the oriented polymer during sealing. Random copolymers containing 3–7% ethylene are often used as sealing layers; the lower melting point (<132°C; <270°F) results in a 30% increase in line speeds, and they can be recycled with no significant loss of strength or clarity. Coating or co-extrusion increases the barrier properties of BOPP film, decreasing its permeability to gases. Common barrier polymers are ethylene vinyl alcohol, polyvinylidene chloride, and polyamide; five or more layers may be co-extruded or laminated, or the barrier polymer can be dispersed in the matrix polymer.
